+Subject: ACPICA: Fix exception code class checks
+
+From: Maximilian Luz <luzmaximilian@gmail.com>
+
+[ Upstream commit 3dfaea3811f8b6a89a347e8da9ab862cdf3e30fe ]
+
+ACPICA commit 1a3a549286ea9db07d7ec700e7a70dd8bcc4354e
+
+The macros to classify different AML exception codes are broken. For
+instance,
+
+ ACPI_ENV_EXCEPTION(Status)
+
+will always evaluate to zero due to
+
+ #define AE_CODE_ENVIRONMENTAL 0x0000
+ #define ACPI_ENV_EXCEPTION(Status) (Status & AE_CODE_ENVIRONMENTAL)
+
+Similarly, ACPI_AML_EXCEPTION(Status) will evaluate to a non-zero
+value for error codes of type AE_CODE_PROGRAMMER, AE_CODE_ACPI_TABLES,
+as well as AE_CODE_AML, and not just AE_CODE_AML as the name suggests.
+
+This commit fixes those checks.
+
+Fixes: d46b6537f0ce ("ACPICA: AML Parser: ignore all exceptions resulting from incorrect AML during table load")

+Subject: amba: Fix resource leak for drivers without .remove
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
+
+[ Upstream commit de5d7adb89367bbc87b4e5ce7afe7ae9bd86dc12 ]
+
+Consider an amba driver with a .probe but without a .remove callback (e.g.
+pl061_gpio_driver). The function amba_probe() is called to bind a device
+and so dev_pm_domain_attach() and others are called. As there is no remove
+callback amba_remove() isn't called at unbind time however and so calling
+dev_pm_domain_detach() is missed and the pm domain keeps active.
+
+To fix this always use the core driver callbacks and handle missing amba
+callbacks there. For probe refuse registration as a driver without probe
+doesn't make sense.

+Subject: ARM: 9046/1: decompressor: Do not clear SCTLR.nTLSMD for ARMv7+ cores
+
+From: Vladimir Murzin <vladimir.murzin@arm.com>
+
+[ Upstream commit 2acb909750431030b65a0a2a17fd8afcbd813a84 ]
+
+It was observed that decompressor running on hardware implementing ARM v8.2
+Load/Store Multiple Atomicity and Ordering Control (LSMAOC), say, as guest,
+would stuck just after:
+
+Uncompressing Linux... done, booting the kernel.
+
+The reason is that it clears nTLSMD bit when disabling caches:
+
+ nTLSMD, bit [3]
+
+ When ARMv8.2-LSMAOC is implemented:
+
+ No Trap Load Multiple and Store Multiple to
+ Device-nGRE/Device-nGnRE/Device-nGnRnE memory.
+
+ 0b0 All memory accesses by A32 and T32 Load Multiple and Store
+ Multiple at EL1 or EL0 that are marked at stage 1 as
+ Device-nGRE/Device-nGnRE/Device-nGnRnE memory are trapped and
+ generate a stage 1 Alignment fault.
+
+ 0b1 All memory accesses by A32 and T32 Load Multiple and Store
+ Multiple at EL1 or EL0 that are marked at stage 1 as
+ Device-nGRE/Device-nGnRE/Device-nGnRnE memory are not trapped.
+
+ This bit is permitted to be cached in a TLB.
+
+ This field resets to 1.
+
+ Otherwise:
+
+ Reserved, RES1
+
+So as effect we start getting traps we are not quite ready for.
+
+Looking into history it seems that mask used for SCTLR clear came from
+the similar code for ARMv4, where bit[3] is the enable/disable bit for
+the write buffer. That not applicable to ARMv7 and onwards, so retire
+that bit from the masks.
+

+
+From: Tony Lindgren <tony@atomide.com>
+
+[ Upstream commit 44f416879a442600b006ef7dec3a6dc98bcf59c6 ]
+
+We have gpio_86 wired internally to the bandgap thermal shutdown
+interrupt on 4430 like we have it on 4460 according to the TRM.
+This can be found easily by searching for TSHUT.
+
+For some reason the thermal shutdown interrupt was never added
+for 4430, let's add it. I believe this is needed for the thermal
+shutdown interrupt handler ti_bandgap_tshut_irq_handler() to call
+orderly_poweroff().

+Subject: arm64: Add missing ISB after invalidating TLB in __primary_switch
+
+From: Marc Zyngier <maz@kernel.org>
+
+[ Upstream commit 9d41053e8dc115c92b8002c3db5f545d7602498b ]
+
+Although there has been a bit of back and forth on the subject, it
+appears that invalidating TLBs requires an ISB instruction when FEAT_ETS
+is not implemented by the CPU.
+
+From the bible:
+
+ | In an implementation that does not implement FEAT_ETS, a TLB
+ | maintenance instruction executed by a PE, PEx, can complete at any
+ | time after it is issued, but is only guaranteed to be finished for a
+ | PE, PEx, after the execution of DSB by the PEx followed by a Context
+ | synchronization event
+
+Add the missing ISB in __primary_switch, just in case.

+
+From: Andre Przywara <andre.przywara@arm.com>
+
+[ Upstream commit 948c657cc45e8ce48cb533d4e2106145fa765759 ]
+
+In contrast to the H6 (and later) manuals, the A64 datasheet does not
+specify any limitations in the maximum possible frequency for eMMC
+controllers.
+However experimentation has found that a 150 MHz limit similar to other
+SoCs and also the MMC0 and MMC1 controllers on the A64 seems to exist
+for the MMC2 controller.
+
+Limit the frequency for the MMC2 controller to 150 MHz in the SoC .dtsi.
+The Pinebook seems to be the an odd exception, since it apparently seems
+to work with 200 MHz as well, so overwrite this in its board .dts file.
+
+Tested on a Pine64-LTS: 200 MHz HS-200 fails, 150 MHz HS-200 works.

+
+From: Andre Przywara <andre.przywara@arm.com>
+
+[ Upstream commit cc72570747e43335f4933a24dd74d5653639176a ]
+
+In recent Allwinner SoCs the first USB host controller (HCI0) shares
+the first PHY with the MUSB controller. Probably to make this sharing
+work, we were avoiding to declare this in the DT. This has two
+shortcomings:
+- U-Boot (which uses the same .dts) cannot use this port in host mode
+ without a PHY linked, so we were loosing one USB port there.
+- It requires the MUSB driver to be enabled and loaded, although we
+ don't actually use it.
+
+To avoid those issues, let's add this PHY link to the A64 .dtsi file.
+After all PHY port 0 *is* connected to HCI0, so we should describe
+it as this. Remove the part from the Pinebook DTS which already had
+this property.
+
+This makes it work in U-Boot, also improves compatiblity when no MUSB
+driver is loaded (for instance in distribution installers).

+Subject: arm64: dts: allwinner: Drop non-removable from SoPine/LTS SD card
+
+From: Andre Przywara <andre.przywara@arm.com>
+
+[ Upstream commit 941432d007689f3774646e41a1439228b6c6ee0e ]
+
+The SD card on the SoPine SoM module is somewhat concealed, so was
+originally defined as "non-removable".
+However there is a working card-detect pin (tested on two different
+SoM versions), and in certain SoM base boards it might be actually
+accessible at runtime.
+Also the Pine64-LTS shares the SoPine base .dtsi, so inherited the
+non-removable flag, even though the SD card slot is perfectly accessible
+and usable there. (It turns out that just *my* board has a broken card
+detect switch, so I originally thought CD wouldn't work on the LTS.)
+
+Drop the "non-removable" flag to describe the SD card slot properly.

+Subject: arm64: dts: allwinner: H6: Allow up to 150 MHz MMC bus frequency
+
+From: Andre Przywara <andre.przywara@arm.com>
+
+[ Upstream commit cfe6c487b9a1abc6197714ec5605716a5428cf03 ]
+
+The H6 manual explicitly lists a frequency limit of 150 MHz for the bus
+frequency of the MMC controllers. So far we had no explicit limits in the
+DT, which limited eMMC to the spec defined frequencies, or whatever the
+driver defines (both Linux and FreeBSD use 52 MHz here).
+
+Put those maximum frequencies in the SoC .dtsi, to allow higher speed
+modes (which still would need to be explicitly enabled, per board).
+
+Tested with an eMMC using HS-200 on a Pine H64. Running at the spec'ed
+200 MHz indeed fails with I/O errors, but 150 MHz seems to work stably.

+Subject: arm64: dts: allwinner: H6: properly connect USB PHY to port 0
+
+From: Andre Przywara <andre.przywara@arm.com>
+
+[ Upstream commit da2fb8457f71138d455cba82edec0d34f858e506 ]
+
+In recent Allwinner SoCs the first USB host controller (HCI0) shares
+the first PHY with the MUSB controller. Probably to make this sharing
+work, we were avoiding to declare this in the DT. This has two
+shortcomings:
+- U-Boot (which uses the same .dts) cannot use this port in host mode
+ without a PHY linked, so we were loosing one USB port there.
+- It requires the MUSB driver to be enabled and loaded, although we
+ don't actually use it.
+
+To avoid those issues, let's add this PHY link to the H6 .dtsi file.
+After all PHY port 0 *is* connected to HCI0, so we should describe
+it as this.
+
+This makes it work in U-Boot, also improves compatiblity when no MUSB
+driver is loaded (for instance in distribution installers).

+
+The partition called "u-boot" in reality contains TF-A and U-Boot, and
+TF-A is before U-Boot.
+
+Rename this parition to "a53-firmware" to avoid confusion for users,
+since they cannot simply build U-Boot from U-Boot repository and flash
+the resulting image there. Instead they have to build the firmware with
+the sources from the mox-boot-builder repository [1] and flash the
+a53-firmware.bin binary there.

+Subject: ASoC: cpcap: fix microphone timeslot mask
+
+From: Sebastian Reichel <sre@kernel.org>
+
+[ Upstream commit de5bfae2fd962a9da99f56382305ec7966a604b9 ]
+
+The correct mask is 0x1f8 (Bit 3-8), but due to missing BIT() 0xf (Bit
+0-3) was set instead. This means setting of CPCAP_BIT_MIC1_RX_TIMESLOT0
+(Bit 3) still worked (part of both masks). On the other hand the code
+does not properly clear the other MIC timeslot bits. I think this
+is not a problem, since they are probably initialized to 0 and not
+touched by the driver anywhere else. But the mask also contains some
+wrong bits, that will be cleared. Bit 0 (CPCAP_BIT_SMB_CDC) should be
+safe, since the driver enforces it to be 0 anyways.
+
+Bit 1-2 are CPCAP_BIT_FS_INV and CPCAP_BIT_CLK_INV. This means enabling
+audio recording forces the codec into SND_SOC_DAIFMT_NB_NF mode, which
+is obviously bad.
+
+The bug probably remained undetected, because there are not many use
+cases for routing microphone to the CPU on platforms using cpcap and
+user base is small. I do remember having some issues with bad sound
+quality when testing voice recording back when I wrote the driver.
+It probably was this bug.

+Subject: ASoC: SOF: debug: Fix a potential issue on string buffer termination
+
+From: Hui Wang <hui.wang@canonical.com>
+
+[ Upstream commit 9037c3bde65d339017ef41d81cb58069ffc321d4 ]
+
+The function simple_write_to_buffer() doesn't add string termination
+at the end of buf, we need to handle it on our own. This change refers
+to the function tokenize_input() in debug.c and the function
+sof_dfsentry_trace_filter_write() in trace.c.

+
+[ Upstream commit 10340f8d7b6dd54e616339c8ccb2f397133ebea0 ]
+
+While reworking the resources management and departing from using
+ahci_platform_enable_resources() which did not allow a proper step
+separation like we need, we unfortunately lost the ability to control
+AHCI regulators. This broke some Broadcom STB systems that do expect
+regulators to be turned on to link up with attached hard drives.

+
+The "REG_READ(ah, AR_PHY_AGC_CONTROL)" in ath9k_hw_loadnf() does not
+like being called when the hardware is asleep, leading to this crash.
+
+The easiest way to reproduce this is trying to set nf_override while
+the hardware is down:
+
+ $ ip link set down dev wlan0
+ $ echo "-85" > /sys/kernel/debug/ieee80211/phy0/ath9k/nf_override
+
+Fixing this crash by waking the hardware up before trying to set the
+noise floor. Similar to what other ath9k debugfs files do.
+
+Tested on a Lima board from 8devices, which has a QCA 4531 chipset.

+
+In btusb_mtk_wmt_recv if skb_clone fails, the alocated skb should be
+released.
+
+Omit the labels “err_out” and “err_free_skb” in this function
+implementation so that the desired exception handling code

+Subject: Bluetooth: hci_uart: Fix a race for write_work scheduling
+
+From: Claire Chang <tientzu@chromium.org>
+
+[ Upstream commit afe0b1c86458f121b085271e4f3034017a90d4a3 ]
+
+In hci_uart_write_work, there is a loop/goto checking the value of
+HCI_UART_TX_WAKEUP. If HCI_UART_TX_WAKEUP is set again, it keeps trying
+hci_uart_dequeue; otherwise, it clears HCI_UART_SENDING and returns.
+
+In hci_uart_tx_wakeup, if HCI_UART_SENDING is already set, it sets
+HCI_UART_TX_WAKEUP, skips schedule_work and assumes the running/pending
+hci_uart_write_work worker will do hci_uart_dequeue properly.
+
+However, if the HCI_UART_SENDING check in hci_uart_tx_wakeup is done after
+the loop breaks, but before HCI_UART_SENDING is cleared in
+hci_uart_write_work, the schedule_work is skipped incorrectly.
+
+Fix this race by changing the order of HCI_UART_SENDING and
+HCI_UART_TX_WAKEUP modification.

+Subject: bpf: Fix bpf_fib_lookup helper MTU check for SKB ctx
+
+From: Jesper Dangaard Brouer <brouer@redhat.com>
+
+[ Upstream commit 2c0a10af688c02adcf127aad29e923e0056c6b69 ]
+
+BPF end-user on Cilium slack-channel (Carlo Carraro) wants to use
+bpf_fib_lookup for doing MTU-check, but *prior* to extending packet size,
+by adjusting fib_params 'tot_len' with the packet length plus the expected
+encap size. (Just like the bpf_check_mtu helper supports). He discovered
+that for SKB ctx the param->tot_len was not used, instead skb->len was used
+(via MTU check in is_skb_forwardable() that checks against netdev MTU).
+
+Fix this by using fib_params 'tot_len' for MTU check. If not provided (e.g.
+zero) then keep existing TC behaviour intact. Notice that 'tot_len' for MTU
+check is done like XDP code-path, which checks against FIB-dst MTU.
+
+V16:
+- Revert V13 optimization, 2nd lookup is against egress/resulting netdev
+
+V13:
+- Only do ifindex lookup one time, calling dev_get_by_index_rcu().
+
+V10:
+- Use same method as XDP for 'tot_len' MTU check

+Subject: bpf_lru_list: Read double-checked variable once without lock
+
+From: Marco Elver <elver@google.com>
+
+[ Upstream commit 6df8fb83301d68ea0a0c0e1cbcc790fcc333ed12 ]
+
+For double-checked locking in bpf_common_lru_push_free(), node->type is
+read outside the critical section and then re-checked under the lock.
+However, concurrent writes to node->type result in data races.
+
+For example, the following concurrent access was observed by KCSAN:
+
+ write to 0xffff88801521bc22 of 1 bytes by task 10038 on cpu 1:
+ __bpf_lru_node_move_in kernel/bpf/bpf_lru_list.c:91
+ __local_list_flush kernel/bpf/bpf_lru_list.c:298
+ ...
+ read to 0xffff88801521bc22 of 1 bytes by task 10043 on cpu 0:
+ bpf_common_lru_push_free kernel/bpf/bpf_lru_list.c:507
+ bpf_lru_push_free kernel/bpf/bpf_lru_list.c:555
+ ...
+
+Fix the data races where node->type is read outside the critical section
+(for double-checked locking) by marking the access with READ_ONCE() as
+well as ensuring the variable is only accessed once.

+

+
+When someone is silly enough to have the same underlying uid as the

+Subject: certs: Fix blacklist flag type confusion
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: David Howells <dhowells@redhat.com>
+
+[ Upstream commit 4993e1f9479a4161fd7d93e2b8b30b438f00cb0f ]
+
+KEY_FLAG_KEEP is not meant to be passed to keyring_alloc() or key_alloc(),
+as these only take KEY_ALLOC_* flags. KEY_FLAG_KEEP has the same value as
+KEY_ALLOC_BYPASS_RESTRICTION, but fortunately only key_create_or_update()
+uses it. LSMs using the key_alloc hook don't check that flag.
+
+KEY_FLAG_KEEP is then ignored but fortunately (again) the root user cannot
+write to the blacklist keyring, so it is not possible to remove a key/hash
+from it.
+
+Fix this by adding a KEY_ALLOC_SET_KEEP flag that tells key_alloc() to set
+KEY_FLAG_KEEP on the new key. blacklist_init() can then, correctly, pass
+this to keyring_alloc().
+
+We can also use this in ima_mok_init() rather than setting the flag
+manually.
+
+Note that this doesn't fix an observable bug with the current
+implementation but it is required to allow addition of new hashes to the
+blacklist in the future without making it possible for them to be removed.

+
+[ Upstream commit 9e717285f0bd591d716fa0e7418f2cdaf756dd25 ]
+
+The error codes returned by meson_clk_get_pll_settings() are all
+negative. Make "ret" a signed integer in meson_clk_pll_set_rate() to
+make it match with the clk_ops.set_rate API as well as the data type
+returned by meson_clk_get_pll_settings().

+Subject: clk: qcom: gcc-msm8998: Fix Alpha PLL type for all GPLLs
+
+From: AngeloGioacchino Del Regno <angelogioacchino.delregno@somainline.org>
+
+[ Upstream commit 292f75ecff07e8a07fe2e3e19b4b567d0b698842 ]
+
+All of the GPLLs in the MSM8998 Global Clock Controller are Fabia PLLs
+and not generic alphas: this was producing bad effects over the entire
+clock tree of MSM8998, where any GPLL child clock was declaring a false
+clock rate, due to their parent also showing the same.
+
+The issue resides in the calculation of the clock rate for the specific
+Alpha PLL type, where Fabia has a different register layout; switching
+the MSM8998 GPLLs to the correct Alpha Fabia PLL type fixes the rate
+(calculation) reading. While at it, also make these PLLs fixed since
+their rate is supposed to *never* be changed while the system runs, as
+this would surely crash the entire SoC.
+
+Now all the children of all the PLLs are also complying with their
+specified clock table and system stability is improved.

+
+[ Upstream commit 756650820abd4770c4200763505b634a3c04e05e ]
+
+The CEC clock on the H6 SoC is a bit special, since it uses a fixed
+pre-dividier for one source clock (the PLL), but conveys the other clock
+(32K OSC) directly.
+We are using a fixed predivider array for that, but fail to use the right
+flag to actually activate that.

+Subject: clk: sunxi-ng: h6: Fix clock divider range on some clocks
+
+From: Andre Przywara <andre.przywara@arm.com>
+
+[ Upstream commit 04ef679591c76571a9e7d5ca48316cc86fa0ef12 ]
+
+While comparing clocks between the H6 and H616, some of the M factor
+ranges were found to be wrong: the manual says they are only covering
+two bits [1:0], but our code had "5" in the number-of-bits field.
+
+By writing 0xff into that register in U-Boot and via FEL, it could be
+confirmed that bits [4:2] are indeed masked off, so the manual is right.
+
+Change to number of bits in the affected clock's description.

+From: Arnd Bergmann <arnd@arndb.de>
+
+[ Upstream commit 7a3b8758bd6e45f7b671723b5c9fa2b69d0787ae ]
+
+Compile-testing the ixp4xx timer with CONFIG_OF enabled but
+CONFIG_TIMER_OF disabled leads to a harmless warning:
+
+arm-linux-gnueabi-ld: warning: orphan section `__timer_of_table' from `drivers/clocksource/timer-ixp4xx.o' being placed in section `__timer_of_table'
+
+Move the select statement from the platform code into the driver
+so it always gets enabled in configurations that rely on it.

+[ Upstream commit 9bc3dd24e7dccd50757db743a3635ad5b0497e6e ]
+
+With the recent kmap change, some tests which were conditional on
+CONFIG_DEBUG_HIGHMEM now are enabled by default.
+This permit to detect a problem in sun4i-ss usage of kmap.
+
+sun4i-ss uses two kmap via sg_miter (one for input, one for output), but
+using two kmap at the same time is hard:
+"the ordering has to be correct and with sg_miter that's probably hard to get
+right." (quoting Tlgx)
+
+So the easiest solution is to never have two sg_miter/kmap open at the same time.
+After each use of sg_miter, I store the current index, for being able to
+resume sg_miter to the right place.

+Subject: crypto: sun4i-ss - linearize buffers content must be kept
+
+From: Corentin Labbe <clabbe@baylibre.com>
+
+[ Upstream commit 583513510a7acd2306787865bcd19ebb2f629d42 ]
+
+When running the non-optimized cipher function, SS produce partial random
+output.
+This is due to linearize buffers being reseted after each loop.
+
+For preserving stack, instead of moving them back to start of function,
+I move them in sun4i_ss_ctx.

+Subject: crypto: talitos - Work around SEC6 ERRATA (AES-CTR mode data size
+ error)
+
+From: Christophe Leroy <christophe.leroy@csgroup.eu>
+
+[ Upstream commit 416b846757bcea20006a9197e67ba3a8b5b2a680 ]
+
+Talitos Security Engine AESU considers any input
+data size that is not a multiple of 16 bytes to be an error.
+This is not a problem in general, except for Counter mode
+that is a stream cipher and can have an input of any size.
+
+Test Manager for ctr(aes) fails on 4th test vector which has
+a length of 499 while all previous vectors which have a 16 bytes
+multiple length succeed.
+
+As suggested by Freescale, round up the input data length to the
+nearest 16 bytes.

+
+[ Upstream commit 2355a6773a2cb0d2dce13432dde78497f1d6617b ]
+
+The Max imm data size in cxgb4 is not similar to the max imm data size
+in the chtls. This caused an mismatch in output of is_ofld_imm() of
+cxgb4 and chtls. So fixed this by keeping the max wreq size of imm data
+same in both chtls and cxgb4 as MAX_IMM_OFLD_TX_DATA_WR_LEN.
+
+As cxgb4's max imm. data value for ofld packets is changed to
+MAX_IMM_OFLD_TX_DATA_WR_LEN. Using the same in cxgbit also.

+
+[ Upstream commit 035b73b2b3b2e074a56489a7bf84b6a8012c0e0d ]
+
+On Intel Tangier B0 and Anniedale the interrupt line, disregarding
+to have different numbers, is shared between HSU DMA and UART IPs.
+Thus on such SoCs we are expecting that IRQ handler is called in
+UART driver only. hsu_pci_irq was handling the spurious interrupt
+from HSU DMA by returning immediately. This wastes CPU time and
+since HSU DMA and HSU UART interrupt occur simultaneously they race
+to be handled causing delay to the HSU UART interrupt handling.
+Fix this by disabling the interrupt entirely.

+From: Andrea Parri (Microsoft) <parri.andrea@gmail.com>
+
+[ Upstream commit e3fa4b747f085d2cda09bba0533b86fa76038635 ]
+
+When channel->device_obj is non-NULL, vmbus_onoffer_rescind() could
+invoke put_device(), that will eventually release the device and free
+the channel object (cf. vmbus_device_release()). However, a pointer
+to the object is dereferenced again later to load the primary_channel.
+The use-after-free can be avoided by noticing that this load/check is
+redundant if device_obj is non-NULL: primary_channel must be NULL if
+device_obj is non-NULL, cf. vmbus_add_channel_work().

+Subject: drm/amd/display: Fix 10/12 bpc setup in DCE output bit depth
+ reduction.
+
+From: Mario Kleiner <mario.kleiner.de@gmail.com>
+
+[ Upstream commit 1916866dfa4aaceba1a70db83fde569387649d93 ]
+
+In set_clamp(), the comments and definitions for the COLOR_DEPTH_101010
+and COLOR_DEPTH_121212 cases directly contradict the code comment which
+explains how this should work, whereas the COLOR_DEPTH_888 case
+is consistent with the code comments. Comment says the bitmask should
+be chosen to align to the top-most 10 or 12 MSB's on a 14 bit bus, but
+the implementation contradicts that: 10 bit case sets a mask for 12 bpc
+clamping, whereas 12 bit case sets a mask for 14 bpc clamping.
+
+Note that during my limited testing on DCE-8.3 (HDMI deep color)
+and DCE-11.2 (DP deep color), this didn't have any obvious ill
+effects, neither did fixing it change anything obvious for the
+better, so this fix may be inconsequential on DCE, and just
+reduce the confusion of innocent bystanders when reading the code
+and trying to investigate problems with 10 bpc+ output.

+Subject: drm/amd/display: Fix HDMI deep color output for DCE 6-11.
+
+From: Mario Kleiner <mario.kleiner.de@gmail.com>
+
+[ Upstream commit efa18405baa55a864c61d2f3cc6fe4d363818eb3 ]
+
+This fixes corrupted display output in HDMI deep color
+10/12 bpc mode at least as observed on AMD Mullins, DCE-8.3.
+
+It will hopefully also provide fixes for other DCE's up to
+DCE-11, assuming those will need similar fixes, but i could
+not test that for HDMI due to lack of suitable hw, so viewer
+discretion is advised.
+
+dce110_stream_encoder_hdmi_set_stream_attribute() is used for
+HDMI setup on all DCE's and is missing color_depth assignment.
+
+dce110_program_pix_clk() is used for pixel clock setup on HDMI
+for DCE 6-11, and is missing color_depth assignment.
+
+Additionally some of the underlying Atombios specific encoder
+and pixelclock setup functions are missing code which is in
+the classic amdgpu kms modesetting path and the in the radeon
+kms driver for DCE6/DCE8.
+
+encoder_control_digx_v3() - Was missing setup code wrt. amdgpu
+and radeon kms classic drivers. Added here, but untested due to
+lack of suitable test hw.
+
+encoder_control_digx_v4() - Added missing setup code.
+Successfully tested on AMD mullins / DCE-8.3 with HDMI deep color
+output at 10 bpc and 12 bpc.
+
+Note that encoder_control_digx_v5() has proper setup code in place
+and is used, e.g., by DCE-11.2, but this code wasn't used for deep
+color setup due to the missing cntl.color_depth setup in the calling
+function for HDMI.
+
+set_pixel_clock_v5() - Missing setup code wrt. classic amdgpu/radeon
+kms. Added here, but untested due to lack of hw.
+
+set_pixel_clock_v6() - Missing setup code added. Successfully tested
+on AMD mullins DCE-8.3. This fixes corrupted display output at HDMI
+deep color output with 10 bpc or 12 bpc.

+leads to shift wrapping. The undefined behavior will lead to a

+From: Iskren Chernev <iskren.chernev@gmail.com>
+
+[ Upstream commit 68e4f01fddb4ead80e8c7084db489307f22c9cbb ]
+
+Before the offending commit in msm_atomic_commit_tail wait_flush was
+called once per frame, after the commit was submitted. After it
+wait_flush is also called at the beginning to ensure previous
+potentially async commits are done.
+
+For cmd panels the source of wait_flush is a ping-pong irq notifying
+a completion. The completion needs to be notified with complete_all so
+multiple waiting parties (new async committers) can proceed.

+Subject: drm/sun4i: tcon: fix inverted DCLK polarity
+
+From: Giulio Benetti <giulio.benetti@micronovasrl.com>
+
+[ Upstream commit 67f4aeb2b41a0629abde3794d463547f60b0cbdd ]
+
+During commit 88bc4178568b ("drm: Use new
+DRM_BUS_FLAG_*_(DRIVE|SAMPLE)_(POS|NEG)EDGE flags") DRM_BUS_FLAG_*
+macros have been changed to avoid ambiguity but just because of this
+ambiguity previous DRM_BUS_FLAG_PIXDATA_(POS/NEG)EDGE were used meaning
+_SAMPLE_ not _DRIVE_. This leads to DLCK inversion and need to fix but
+instead of swapping phase values, let's adopt an easier approach Maxime
+suggested:
+It turned out that bit 26 of SUN4I_TCON0_IO_POL_REG is dedicated to
+invert DCLK polarity and this makes things really easier than before. So
+let's handle DCLK polarity by adding SUN4I_TCON0_IO_POL_DCLK_DRIVE_NEGEDGE
+as bit 26 and activating according to bus_flags the same way it is done
+for all the other signals polarity.

+Subject: ext4: fix potential htree index checksum corruption
+
+From: Theodore Ts'o <tytso@mit.edu>
+
+[ Upstream commit b5776e7524afbd4569978ff790864755c438bba7 ]
+
+In the case where we need to do an interior node split, and
+immediately afterwards, we are unable to allocate a new directory leaf
+block due to ENOSPC, the directory index checksum's will not be filled
+in correctly (and indeed, will not be correctly journalled).
+
+This looks like a bug that was introduced when we added largedir
+support. The original code doesn't make any sense (and should have
+been caught in code review), but it was hidden because most of the
+time, the index node checksum will be set by do_split(). But if
+do_split bails out due to ENOSPC, then ext4_handle_dirty_dx_node()
+won't get called, and so the directory index checksum field will not
+get set, leading to:
+
+EXT4-fs error (device sdb): dx_probe:858: inode #6635543: block 4022: comm nfsd: Directory index failed checksum

+
+From: Yi Chen <chenyi77@huawei.com>

+[FSCK] next block offset is free [Ok..]
+[FSCK] fixing SIT types
+[FSCK] other corrupted bugs [Fail]
+
+The root cause is:
+If we open file w/ readonly flag, disk quota info won't be initialized
+for this file, however, following mmap() will force to convert inline
+inode via f2fs_convert_inline_inode(), which may increase block usage
+for this inode w/o updating quota data, it causes inconsistent disk quota
+info.
+
+The issue will happen in following stack:
+open(file, O_RDONLY)
+mmap(file)
+- f2fs_convert_inline_inode
+ - f2fs_convert_inline_page
+ - f2fs_reserve_block
+ - f2fs_reserve_new_block
+ - f2fs_reserve_new_blocks
+ - f2fs_i_blocks_write
+ - dquot_claim_block
+inode->i_blocks increase, but the dqb_curspace keep the size for the dquots
+is NULL.
+
+To fix this issue, let's call dquot_initialize() anyway in both
+f2fs_truncate() and f2fs_convert_inline_inode() functions to avoid potential
+inconsistent quota data issue.

+From: Randy Dunlap <rdunlap@infradead.org>
+
+[ Upstream commit c6c90c70db4d9a0989111d6b994d545659410f7a ]
+
+It looks like SPARC64 requires FB_ATY_CT to build without errors,
+so have FB_ATY select FB_ATY_CT if both SPARC64 and PCI are enabled
+instead of using "default y if SPARC64 && PCI", which is not strong
+enough to prevent build errors.
+
+As it currently is, FB_ATY_CT can be disabled, resulting in build
+errors:

+Mark the memory region with NOMAP flag instead of completely removing it
+from the memory blocks. That makes the FDT handling consistent with the EFI

+
+The left shift of int 32 bit integer constant 1 is evaluated using 32 bit
+arithmetic and then assigned to a signed 64 bit integer. In the case where
+l2nb is 32 or more this can lead to an overflow. Avoid this by shifting

+
+From: Dan Carpenter <dan.carpenter@oracle.com>
+
+[ Upstream commit 15ccc39b3aab667c6fa131206f01f31bfbccdf6a ]
+
+The main problem with this error handling was that it didn't clean up if
+i2c_add_numbered_adapter() failed. This code is pretty old, and doesn't
+match with today's checkpatch.pl standards so I took the opportunity to
+tidy it up a bit. I changed the NULL comparison, and removed the
+WARNING message if kzalloc() fails and updated the label names.

+Subject: HID: core: detect and skip invalid inputs to snto32()
+
+From: Randy Dunlap <rdunlap@infradead.org>
+
+[ Upstream commit a0312af1f94d13800e63a7d0a66e563582e39aec ]
+
+Prevent invalid (0, 0) inputs to hid-core's snto32() function.
+
+Maybe it is just the dummy device here that is causing this, but
+there are hundreds of calls to snto32(0, 0). Having n (bits count)
+of 0 is causing the current UBSAN trap with a shift value of
+0xffffffff (-1, or n - 1 in this function).
+
+Either of the value to shift being 0 or the bits count being 0 can be
+handled by just returning 0 to the caller, avoiding the following
+complex shift + OR operations:
+
+ return value & (1 << (n - 1)) ? value | (~0U << n) : value;

+If the hardware is still accessing memory after SMMU translation

+
+From: Rayagonda Kokatanur <rayagonda.kokatanur@broadcom.com>
+
+[ Upstream commit 545f4011e156554d704d6278245d54543f6680d1 ]
+
+Handle only slave interrupts which are enabled.
+
+The IS_OFFSET register contains the interrupt status bits which will be
+set regardless of the enabling of the corresponding interrupt condition.
+One must therefore look at both IS_OFFSET and IE_OFFSET to determine
+whether an interrupt condition is set and enabled.

+Subject: i2c: qcom-geni: Store DMA mapping data in geni_i2c_dev struct
+
+From: Roja Rani Yarubandi <rojay@codeaurora.org>
+
+[ Upstream commit 357ee8841d0b7bd822f25fc768afbc0c2ab7e47b ]
+
+Store DMA mapping data in geni_i2c_dev struct to enhance DMA mapping
+data scope. For example during shutdown callback to unmap DMA mapping,
+this stored DMA mapping data can be used to call geni_se_tx_dma_unprep
+and geni_se_rx_dma_unprep functions.
+
+Add two helper functions geni_i2c_rx_msg_cleanup and
+geni_i2c_tx_msg_cleanup to unwrap the things after rx/tx FIFO/DMA
+transfers, so that the same can be used in geni_i2c_stop_xfer()
+function during shutdown callback.

+
+[ Upstream commit 28b1208e7a7fa3ddc9345b022bb93e53d9dcc28a ]
+
+Fix addition of VLAN filter for PF after enabling FW LLDP agent.
+Changing LLDP Agent causes FW to re-initialize per NVM settings.
+Remove default PF filter and move "Enable/Disable" to currently used
+reset flag.
+Without this patch PF would try to add MAC VLAN filter with default
+switch filter present. This causes AQ error and sets promiscuous mode
+on.

+Subject: i40e: Fix flow for IPv6 next header (extension header)
+
+From: Slawomir Laba <slawomirx.laba@intel.com>
+
+[ Upstream commit 92c6058024e87087cf1b99b0389d67c0a886360e ]
+
+When a packet contains an IPv6 header with next header which is
+an extension header and not a protocol one, the kernel function
+skb_transport_header called with such sk_buff will return a
+pointer to the extension header and not to the TCP one.
+
+The above explained call caused a problem with packet processing
+for skb with encapsulation for tunnel with I40E_TX_CTX_EXT_IP_IPV6.
+The extension header was not skipped at all.
+
+The ipv6_skip_exthdr function does check if next header of the IPV6
+header is an extension header and doesn't modify the l4_proto pointer
+if it points to a protocol header value so its safe to omit the
+comparison of exthdr and l4.hdr pointers. The ipv6_skip_exthdr can
+return value -1. This means that the skipping process failed
+and there is something wrong with the packet so it will be dropped.

+From: Sylwester Dziedziuch <sylwesterx.dziedziuch@intel.com>
+
+[ Upstream commit dc8812626440fa6a27f1f3f654f6dc435e042e42 ]
+
+When creating VFs they were sometimes not getting resources.
+It was caused by not executing i40e_reset_all_vfs due to
+flag __I40E_VF_DISABLE being set on PF. Because of this
+IAVF was never able to finish setup sequence never
+getting reset indication from PF.
+Changed test_and_set_bit __I40E_VF_DISABLE in
+i40e_sync_filters_subtask to test_bit and removed clear_bit.
+This function should not set this bit it should only check
+if it hasn't been already set.

+Subject: IB/cm: Avoid a loop when device has 255 ports
+
+From: Parav Pandit <parav@nvidia.com>
+
+[ Upstream commit 131be26750379592f0dd6244b2a90bbb504a10bb ]
+
+When RDMA device has 255 ports, loop iterator i overflows. Due to which
+cm_add_one() port iterator loops infinitely. Use core provided port
+iterator to avoid the infinite loop.

+
+From: Tom Rix <trix@redhat.com>

+
+fs/jffs2/summary.c:794:31: warning: Use of memory after it is freed
+ c->summary->sum_list_head = temp->u.next;
+ ^~~~~~~~~~~~
+
+In jffs2_sum_write_data(), in a loop summary data is handles a node at
+a time. When it has written out the node it is removed the summary list,
+and the node is deleted. In the corner case when a
+JFFS2_FEATURE_RWCOMPAT_COPY is seen, a call is made to
+jffs2_sum_disable_collecting(). jffs2_sum_disable_collecting() deletes
+the whole list which conflicts with the loop's deleting the list by parts.
+
+To preserve the old behavior of stopping the write midway, bail out of
+the loop after disabling summary collection.

+
+From: Jacopo Mondi <jacopo@jmondi.org>
+
+[ Upstream commit dc1eb7c9c290cba52937c9a224b22a400bb0ffd7 ]
+
+The driver currently reports a single supported value for
+V4L2_CID_PIXEL_RATE and initializes the control's minimum value to 0,
+which is very risky, as userspace might accidentally use it as divider
+when calculating the time duration of a line.
+
+Fix this by using as minimum the only supported value when registering
+the control.

+Subject: media: imx: Fix csc/scaler unregister
+
+From: Ezequiel Garcia <ezequiel@collabora.com>
+
+[ Upstream commit 89b14485caa4b7b2eaf70be0064f0978e68ebeee ]
+
+The csc/scaler device private struct is released by
+ipu_csc_scaler_video_device_release(), which can be called
+by video_unregister_device() if there are no users
+of the underlying struct video device.
+
+Therefore, the mutex can't be held when calling
+video_unregister_device() as its memory may be freed
+by it, leading to a kernel oops.
+
+Fortunately, the fix is quite simple as no locking
+is needed when calling video_unregister_device(): v4l2-core
+already has its own internal locking, and the structures
+are also properly refcounted.

+From: Ezequiel Garcia <ezequiel@collabora.com>
+
+[ Upstream commit bb2216548a2b13cf2942a058b475438a7a6bb028 ]
+
+The csc/scaler device pointer (imxmd->m2m_vdev) is assigned
+after the imx media device v4l2-async probe completes,
+therefore we need to check if the device is non-NULL

+
+The Renkforce RF AC4K 300 Action Cam 4K reports invalid bFormatIndex and
+bFrameIndex values when negotiating the video probe and commit controls.
+The UVC descriptors report a single supported format and frame size,
+with bFormatIndex and bFrameIndex both equal to 2, but the video probe
+and commit controls report bFormatIndex and bFrameIndex set to 1.
+
+The device otherwise operates correctly, but the driver rejects the
+values and fails the format try operation. Fix it by ignoring the
+invalid indices, and assuming that the format and frame requested by the
+driver are accepted by the device.

+Commit 866b6a89c6d1 ("MIPS: Add DWARF unwinding to assembly") added
+-fno-asynchronous-unwind-tables to KBUILD_CFLAGS to prevent compiler
+from emitting .eh_frame symbols.
+However, as MIPS heavily uses CFI, that's not enough. Use the
+approach taken for x86 (as it also uses CFI) and explicitly put CFI
+symbols into the .debug_frame section (except for VDSO).
+This allows us to drop .eh_frame from DISCARDS as it's no longer
+being generated.

+Subject: misc: eeprom_93xx46: Add module alias to avoid breaking support for
+ non device tree users
+
+From: Aswath Govindraju <a-govindraju@ti.com>
+
+[ Upstream commit 4540b9fbd8ebb21bb3735796d300a1589ee5fbf2 ]
+
+Module alias "spi:93xx46" is used by non device tree users like
+drivers/misc/eeprom/digsy_mtc_eeprom.c and removing it will
+break support for them.
+
+Fix this by adding back the module alias "spi:93xx46".

+Subject: mm/compaction: fix misbehaviors of fast_find_migrateblock()
+
+From: Wonhyuk Yang <vvghjk1234@gmail.com>
+
+[ Upstream commit 15d28d0d11609c7a4f217b3d85e26456d9beb134 ]
+
+In the fast_find_migrateblock(), it iterates ocer the freelist to find the
+proper pageblock. But there are some misbehaviors.
+
+First, if the page we found is equal to cc->migrate_pfn, it is considered
+that we didn't find a suitable pageblock. Secondly, if the loop was
+terminated because order is less than PAGE_ALLOC_COSTLY_ORDER, it could be
+considered that we found a suitable one. Thirdly, if the skip bit is set
+on the page block and we goto continue, it doesn't check nr_scanned.
+Fourthly, if the page block's skip bit is set, it checks that page block
+is the last of list, which is unnecessary.

+
+[ Upstream commit 90a3e375d324b2255b83e3dd29e99e2b05d82aaf ]
+
+Since commit 42e4089c7890 ("x86/speculation/l1tf: Disallow non privileged

+Andi said:
+
+ "While the fix is correct, I'm not sure if it actually is a real bug.

+From: Miaohe Lin <linmiaohe@huawei.com>
+
+[ Upstream commit 5d5d19eda6b0ee790af89c45e3f678345be6f50f ]
+
+For PMD-mapped page (usually THP), pvmw->pte is NULL. For PTE-mapped THP,
+pvmw->pte is mapped. But for HugeTLB pages, pvmw->pte is not mapped and
+set to the relevant page table entry. So in page_vma_mapped_walk_done(),
+we may do pte_unmap() for HugeTLB pte which is not mapped. Fix this by
+checking pvmw->page against PageHuge before trying to do pte_unmap().

+In the case of failure while parsing the partitions, the iterator should

+
+[ Upstream commit 186edbb510bd60e748f93975989ccba25ee99c50 ]

+The current driver calls netif_carrier_off() late in the link tear down

+
+Calling netif_carrier_off() immediately after netif_tx_stop_all_queues()
+avoids the warning.

+
+From: Shyam Sundar S K <Shyam-sundar.S-k@amd.com>
+
+[ Upstream commit 84fe68eb67f9499309cffd97c1ba269de125ff14 ]
+
+Normally, auto negotiation and reconnect should be automatically done by
+the hardware. But there seems to be an issue where auto negotiation has
+to be restarted manually. This happens because of link training and so
+even though still connected to the partner the link never "comes back".
+This needs an auto-negotiation restart.
+
+Also, a change in xgbe-mdio is needed to get ethtool to recognize the
+link down and get the link change message. This change is only
+required in a backplane connection mode.

+
+From: Robert Hancock <robert.hancock@calian.com>
+
+[ Upstream commit 57baf8cc70ea4cf5503c9d42f31f6a86d7f5ff1a ]
+
+This driver is set up to use a clock mapping in the device tree if it is
+present, but still work without one for backward compatibility. However,
+if getting the clock returns -EPROBE_DEFER, then we need to abort and
+return that error from our driver initialization so that the probe can
+be retried later after the clock is set up.
+
+Move clock initialization to earlier in the process so we do not waste as
+much effort if the clock is not yet available. Switch to use
+devm_clk_get_optional and abort initialization on any error reported.
+Also enable the clock regardless of whether the controller is using an MDIO
+bus, as the clock is required in any case.

+
+These pernet operations may depend on stuff set up or torn down in the
+module init/exit functions. And they may be called at any time in
+between. So it makes more sense for them to be the last to be
+registered in the init function, and the first to be unregistered in the
+exit function.
+
+In particular, without this, the drc slab is being destroyed before all
+the per-net drcs are shut down, resulting in an "Objects remaining in
+nfsd_drc on __kmem_cache_shutdown()" warning in exit_nfsd.

+Subject: nvmem: core: skip child nodes not matching binding
+
+From: Ahmad Fatoum <a.fatoum@pengutronix.de>
+
+[ Upstream commit 0445efacec75b85c2a3c176957ee050ba9be53f0 ]
+
+The nvmem cell binding applies to all eeprom child nodes matching
+"^.*@[0-9a-f]+$" without taking a compatible into account.
+
+Linux drivers, like at24, are even more extensive and assume
+_all_ at24 eeprom child nodes to be nvmem cells since e888d445ac33
+("nvmem: resolve cells from DT at registration time").
+
+Since df5f3b6f5357 ("dt-bindings: nvmem: stm32: new property for
+data access"), the additionalProperties: True means it's Ok to have
+other properties as long as they don't match "^.*@[0-9a-f]+$".
+
+The barebox bootloader extends the MTD partitions binding to
+EEPROM and can fix up following device tree node:
+
+ &eeprom {
+ partitions {
+ compatible = "fixed-partitions";
+ };
+ };
+
+This is allowed binding-wise, but drivers using nvmem_register()
+like at24 will fail to parse because the function expects all child
+nodes to have a reg property present. This results in the whole
+EEPROM driver probe failing despite the device tree being correct.
+
+Fix this by skipping nodes lacking a reg property instead of
+returning an error. This effectively makes the drivers adhere
+to the binding because all nodes with a unit address must have
+a reg property and vice versa.

+Subject: of/fdt: Make sure no-map does not remove already reserved regions
+
+From: Nicolas Boichat <drinkcat@chromium.org>
+
+[ Upstream commit 8a5a75e5e9e55de1cef5d83ca3589cb4899193ef ]
+
+If the device tree is incorrectly configured, and attempts to
+define a "no-map" reserved memory that overlaps with the kernel
+data/code, the kernel would crash quickly after boot, with no
+obvious clue about the nature of the issue.
+
+For example, this would happen if we have the kernel mapped at
+these addresses (from /proc/iomem):
+40000000-41ffffff : System RAM
+ 40080000-40dfffff : Kernel code
+ 40e00000-411fffff : reserved
+ 41200000-413e0fff : Kernel data
+
+And we declare a no-map shared-dma-pool region at a fixed address
+within that range:
+mem_reserved: mem_region {
+ compatible = "shared-dma-pool";
+ reg = <0 0x40000000 0 0x01A00000>;
+ no-map;
+};
+
+To fix this, when removing memory regions at early boot (which is
+what "no-map" regions do), we need to make sure that the memory
+is not already reserved. If we do, __reserved_mem_reserve_reg
+will throw an error:
+[ 0.000000] OF: fdt: Reserved memory: failed to reserve memory
+ for node 'mem_region': base 0x0000000040000000, size 26 MiB
+and the code that will try to use the region should also fail,
+later on.
+
+We do not do anything for non-"no-map" regions, as memblock
+explicitly allows reserved regions to overlap, and the commit
+that this fixes removed the check for that precise reason.
+
+[ qperret: fixed conflicts caused by the usage of memblock_mark_nomap ]

+Subject: PCI: Align checking of syscall user config accessors
+
+From: Heiner Kallweit <hkallweit1@gmail.com>
+
+[ Upstream commit ef9e4005cbaf022c6251263aa27836acccaef65d ]
+
+After 34e3207205ef ("PCI: handle positive error codes"),
+pci_user_read_config_*() and pci_user_write_config_*() return 0 or negative
+errno values, not PCIBIOS_* values like PCIBIOS_SUCCESSFUL or
+PCIBIOS_BAD_REGISTER_NUMBER.
+
+Remove comparisons with PCIBIOS_SUCCESSFUL and check only for non-zero. It
+happens that PCIBIOS_SUCCESSFUL is zero, so this is not a functional
+change, but it aligns this code with the user accessors.

+From: Nathan Lynch <nathanl@linux.ibm.com>
+
+[ Upstream commit 768d70e19ba525debd571b36e6d0ab19956c63d7 ]
+
+dlpar_configure_connector() has two problems in its handling of
+ibm,configure-connector's return status:
+
+1. When the status is -2 (busy, call again), we call
+ ibm,configure-connector again immediately without checking whether
+ to schedule, which can result in monopolizing the CPU.
+2. Extended delay status (9900..9905) goes completely unhandled,
+ causing the configuration to unnecessarily terminate.
+
+Fix both of these issues by using rtas_busy_delay().

+If rockchip_pwm_probe() fails to register a PWM device it calls
+clk_unprepare() for the device's PWM clock, without having first disabled

+[ Upstream commit a4db1072e1a3bd7a8d9c356e1902b13ac5deb8ef ]
+
+When checking corrupted quota file we can bail out and leak allocated
+info structure. Properly free info structure on error return.

+From: Bob Pearson <rpearsonhpe@gmail.com>
+
+[ Upstream commit 8fc1b7027fc162738d5a85c82410e501a371a404 ]
+
+rxe_rcv_mcast_pkt() in rxe_recv.c can leak SKBs in error path code. The
+loop over the QPs attached to a multicast group creates new cloned SKBs
+for all but the last QP in the list and passes the SKB and its clones to
+rxe_rcv_pkt() for further processing. Any QPs that do not pass some checks
+are skipped. If the last QP in the list fails the tests the SKB is
+leaked. This patch checks if the SKB for the last QP was used and if not
+frees it. Also removes a redundant loop invariant assignment.

+Subject: RDMA/siw: Fix calculation of tx_valid_cpus size
+
+From: Kamal Heib <kamalheib1@gmail.com>
+
+[ Upstream commit 429fa9698957d1a910535ce5e33aedf5adfdabc1 ]
+
+The size of tx_valid_cpus was calculated under the assumption that the
+numa nodes identifiers are continuous, which is not the case in all archs
+as this could lead to the following panic when trying to access an invalid
+tx_valid_cpus index, avoid the following panic by using nr_node_ids
+instead of num_online_nodes() to allocate the tx_valid_cpus size.

+Subject: RDMA/siw: Fix handling of zero-sized Read and Receive Queues.
+
+From: Bernard Metzler <bmt@zurich.ibm.com>
+
+[ Upstream commit 661f385961f06f36da24cf408d461f988d0c39ad ]
+
+During connection setup, the application may choose to zero-size inbound
+and outbound READ queues, as well as the Receive queue. This patch fixes
+handling of zero-sized queues, but not prevents it.
+
+Kamal Heib says in an initial error report:
+
+ When running the blktests over siw the following shift-out-of-bounds is
+ reported, this is happening because the passed IRD or ORD from the ulp
+ could be zero which will lead to unexpected behavior when calling
+ roundup_pow_of_two(), fix that by blocking zero values of ORD or IRD.
+
+ UBSAN: shift-out-of-bounds in ./include/linux/log2.h:57:13
+ shift exponent 64 is too large for 64-bit type 'long unsigned int'

+Subject: regmap: sdw: use _no_pm functions in regmap_read/write
+
+From: Bard Liao <yung-chuan.liao@linux.intel.com>
+
+[ Upstream commit d288a5712ef961e16d588bbdb2d846e00b5ef154 ]
+
+sdw_update_slave_status will be invoked when a codec is attached,
+and the codec driver will initialize the codec with regmap functions
+while the codec device is pm_runtime suspended.
+
+regmap routines currently rely on regular SoundWire IO functions,
+which will call pm_runtime_get_sync()/put_autosuspend.
+
+This causes a deadlock where the resume routine waits for an
+initialization complete signal that while the initialization complete
+can only be reached when the resume completes.
+
+The only solution if we allow regmap functions to be used in resume
+operations as well as during codec initialization is to use _no_pm
+routines. The duty of making sure the bus is operational needs to be
+handled above the regmap level.

+Subject: regulator: core: Avoid debugfs: Directory ... already present! error
+
+From: Hans de Goede <hdegoede@redhat.com>
+
+[ Upstream commit dbe954d8f1635f949a1d9a5d6e6fb749ae022b47 ]
+
+Sometimes regulator_get() gets called twice for the same supply on the
+same device. This may happen e.g. when a framework / library is used
+which uses the regulator; and the driver itself also needs to enable
+the regulator in some cases where the framework will not enable it.
+
+Commit ff268b56ce8c ("regulator: core: Don't spew backtraces on
+duplicate sysfs") already takes care of the backtrace which would
+trigger when creating a duplicate consumer symlink under
+/sys/class/regulator/regulator.%d in this scenario.
+
+Commit c33d442328f5 ("debugfs: make error message a bit more verbose")
+causes a new error to get logged in this scenario:
+
+[ 26.938425] debugfs: Directory 'wm5102-codec-MICVDD' with parent 'spi-WM510204:00-MICVDD' already present!
+
+There is no _nowarn variant of debugfs_create_dir(), but we can detect
+and avoid this problem by checking the return value of the earlier
+sysfs_create_link_nowarn() call.
+
+Add a check for the earlier sysfs_create_link_nowarn() failing with
+-EEXIST and skip the debugfs_create_dir() call in that case, avoiding
+this error getting logged.
+

+Subject: sched/eas: Don't update misfit status if the task is pinned
+
+From: Qais Yousef <qais.yousef@arm.com>
+
+[ Upstream commit 0ae78eec8aa64e645866e75005162603a77a0f49 ]
+
+If the task is pinned to a cpu, setting the misfit status means that
+we'll unnecessarily continuously attempt to migrate the task but fail.
+
+This continuous failure will cause the balance_interval to increase to
+a high value, and eventually cause unnecessary significant delays in
+balancing the system when real imbalance happens.
+
+Caught while testing uclamp where rt-app calibration loop was pinned to
+cpu 0, shortly after which we spawn another task with high util_clamp
+value. The task was failing to migrate after over 40ms of runtime due to
+balance_interval unnecessary expanded to a very high value from the
+calibration loop.
+
+Not done here, but it could be useful to extend the check for pinning to
+verify that the affinity of the task has a cpu that fits. We could end
+up in a similar situation otherwise.

+From: Randy Dunlap <rdunlap@infradead.org>

+Subject: soc: aspeed: snoop: Add clock control logic
+
+From: Jae Hyun Yoo <jae.hyun.yoo@intel.com>
+
+[ Upstream commit 3f94cf15583be554df7aaa651b8ff8e1b68fbe51 ]
+
+If LPC SNOOP driver is registered ahead of lpc-ctrl module, LPC
+SNOOP block will be enabled without heart beating of LCLK until
+lpc-ctrl enables the LCLK. This issue causes improper handling on
+host interrupts when the host sends interrupt in that time frame.
+Then kernel eventually forcibly disables the interrupt with
+dumping stack and printing a 'nobody cared this irq' message out.
+
+To prevent this issue, all LPC sub-nodes should enable LCLK
+individually so this patch adds clock control logic into the LPC
+SNOOP driver.

+Subject: soundwire: cadence: fix ACK/NAK handling
+
+From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>
+
+[ Upstream commit db9d9f944f95e7f3aa60ac00cbd502415152c421 ]
+
+The existing code reports a NAK only when ACK=0
+This is not aligned with the SoundWire 1.x specifications.
+
+Table 32 in the SoundWire 1.2 specification shows that a Device shall
+not set NAK=1 if ACK=1. But Table 33 shows the Combined Response
+may very well be NAK=1/ACK=1, e.g. if another Device than the one
+addressed reports a parity error.
+
+NAK=1 signals a 'Command_Aborted', regardless of the ACK bit value.
+
+Move the tests for NAK so that the NAK=1/ACK=1 combination is properly
+detected according to the specification.

+
+From: Pratyush Yadav <p.yadav@ti.com>
+
+[ Upstream commit ceeda328edeeeeac7579e9dbf0610785a3b83d39 ]
+
+The controller can only support up to 31 dummy cycles. If the command
+requires more it falls back to using 31. This command is likely to fail
+because the correct number of cycles are not waited upon. Rather than
+silently issuing an incorrect command, fail loudly so the caller can get
+a chance to find out the command can't be supported by the controller.

+Subject: staging: rtl8723bs: wifi_regd.c: Fix incorrect number of regulatory
+ rules
+
+From: Chen-Yu Tsai <wens@csie.org>
+
+[ Upstream commit 61834c967a929f6b4b7fcb91f43fa225cc29aa19 ]
+
+The custom regulatory ruleset in the rtl8723bs driver lists an incorrect
+number of rules: one too many. This results in an out-of-bounds access,
+as detected by KASAN. This was possible thanks to the newly added support
+for KASAN on ARMv7.
+
+Fix this by filling in the correct number of rules given.

+Subject: tcp: fix SO_RCVLOWAT related hangs under mem pressure
+
+From: Eric Dumazet <edumazet@google.com>
+
+[ Upstream commit f969dc5a885736842c3511ecdea240fbb02d25d9 ]
+
+While commit 24adbc1676af ("tcp: fix SO_RCVLOWAT hangs with fat skbs")
+fixed an issue vs too small sk_rcvbuf for given sk_rcvlowat constraint,
+it missed to address issue caused by memory pressure.
+
+1) If we are under memory pressure and socket receive queue is empty.
+First incoming packet is allowed to be queued, after commit
+76dfa6082032 ("tcp: allow one skb to be received per socket under memory pressure")
+
+But we do not send EPOLLIN yet, in case tcp_data_ready() sees sk_rcvlowat
+is bigger than skb length.
+
+2) Then, when next packet comes, it is dropped, and we directly
+call sk->sk_data_ready().
+
+3) If application is using poll(), tcp_poll() will then use
+tcp_stream_is_readable() and decide the socket receive queue is
+not yet filled, so nothing will happen.
+
+Even when sender retransmits packets, phases 2) & 3) repeat
+and flow is effectively frozen, until memory pressure is off.
+
+Fix is to consider tcp_under_memory_pressure() to take care
+of global memory pressure or memcg pressure.

+Subject: tracepoint: Do not fail unregistering a probe due to memory failure
+
+From: Steven Rostedt (VMware) <rostedt@goodmis.org>
+
+[ Upstream commit befe6d946551d65cddbd32b9cb0170b0249fd5ed ]
+
+The list of tracepoint callbacks is managed by an array that is protected
+by RCU. To update this array, a new array is allocated, the updates are
+copied over to the new array, and then the list of functions for the
+tracepoint is switched over to the new array. After a completion of an RCU
+grace period, the old array is freed.
+
+This process happens for both adding a callback as well as removing one.
+But on removing a callback, if the new array fails to be allocated, the
+callback is not removed, and may be used after it is freed by the clients
+of the tracepoint.
+
+There's really no reason to fail if the allocation for a new array fails
+when removing a function. Instead, the function can simply be replaced by a
+stub function that could be cleaned up on the next modification of the
+array. That is, instead of calling the function registered to the
+tracepoint, it would call a stub function in its place.

+Link: https://lkml.kernel.org/r/20201118093405.7a6d2290@gandalf.local.home
+
+[ Note, this version does use undefined compiler behavior (assuming that
+ a stub function with no parameters or return, can be called by a location
+ that thinks it has parameters but still no return value. Static calls
+ do the same thing, so this trick is not without precedent.
+
+ There's another solution that uses RCU tricks and is more complex, but
+ can be an alternative if this solution becomes an issue.

+Subject: usb: dwc2: Abort transaction after errors with unknown reason
+
+From: Guenter Roeck <linux@roeck-us.net>
+
+[ Upstream commit f74b68c61cbc4b2245022fcce038509333d63f6f ]
+
+In some situations, the following error messages are reported.
+
+dwc2 ff540000.usb: dwc2_hc_chhltd_intr_dma: Channel 1 - ChHltd set, but reason is unknown
+dwc2 ff540000.usb: hcint 0x00000002, intsts 0x04000021
+
+This is sometimes followed by:
+
+dwc2 ff540000.usb: dwc2_update_urb_state_abn(): trimming xfer length
+
+and then:
+
+WARNING: CPU: 0 PID: 0 at kernel/v4.19/drivers/usb/dwc2/hcd.c:2913
+ dwc2_assign_and_init_hc+0x98c/0x990
+
+The warning suggests that an odd buffer address is to be used for DMA.
+
+After an error is observed, the receive buffer may be full
+(urb->actual_length >= urb->length). However, the urb is still left in
+the queue unless three errors were observed in a row. When it is queued
+again, the dwc2 hcd code translates this into a 1-block transfer.
+If urb->actual_length (ie the total expected receive length) is not
+DMA-aligned, the buffer pointer programmed into the chip will be
+unaligned. This results in the observed warning.
+
+To solve the problem, abort input transactions after an error with
+unknown cause if the entire packet was already received. This may be
+a bit drastic, but we don't really know why the transfer was aborted
+even though the entire packet was received. Aborting the transfer in
+this situation is less risky than accepting a potentially corrupted
+packet.
+
+With this patch in place, the 'ChHltd set' and 'trimming xfer length'
+messages are still observed, but there are no more transfer attempts
+with odd buffer addresses.

+From: Guenter Roeck <linux@roeck-us.net>
+
+[ Upstream commit 415fa1c7305dedbb345e2cc8ac91769bc1c83f1a ]
+
+The DWC2 documentation states that transfers with zero data length should
+set the number of packets to 1 and the transfer length to 0. This is not
+currently the case for inbound transfers: the transfer length is set to
+the maximum packet length. This can have adverse effects if the chip
+actually does transfer data as it is programmed to do. Follow chip
+documentation and keep the transfer length set to 0 in that situation.

+
+From: Guenter Roeck <linux@roeck-us.net>
+
+[ Upstream commit 1a9e38cabd80356ffb98c2c88fec528ea9644fd5 ]
+
+With some USB network adapters, such as DM96xx, the following message
+is seen for each maximum size receive packet.
+
+dwc2 ff540000.usb: dwc2_update_urb_state(): trimming xfer length
+
+This happens because the packet size requested by the driver is 1522
+bytes, wMaxPacketSize is 64, the dwc2 driver configures the chip to
+receive 24*64 = 1536 bytes, and the chip does indeed send more than
+1522 bytes of data. Since the event does not indicate an error condition,
+the message is just noise. Demote it to debug level.

+Subject: usb: gadget: u_audio: Free requests only after callback
+
+From: Jack Pham <jackp@codeaurora.org>
+
+[ Upstream commit 7de8681be2cde9f6953d3be1fa6ce05f9fe6e637 ]
+
+As per the kernel doc for usb_ep_dequeue(), it states that "this
+routine is asynchronous, that is, it may return before the completion
+routine runs". And indeed since v5.0 the dwc3 gadget driver updated
+its behavior to place dequeued requests on to a cancelled list to be
+given back later after the endpoint is stopped.
+
+The free_ep() was incorrectly assuming that a request was ready to
+be freed after calling dequeue which results in a use-after-free
+in dwc3 when it traverses its cancelled list. Fix this by moving
+the usb_ep_free_request() call to the callback itself in case the
+ep is disabled.

+Subject: VMCI: Use set_page_dirty_lock() when unregistering guest memory
+
+From: Jorgen Hansen <jhansen@vmware.com>
+
+[ Upstream commit 5a16c535409f8dcb7568e20737309e3027ae3e49 ]
+
+When the VMCI host support releases guest memory in the case where
+the VM was killed, the pinned guest pages aren't locked. Use
+set_page_dirty_lock() instead of set_page_dirty().
+
+Testing done: Killed VM while having an active VMCI based vSocket
+connection and observed warning from ext4. With this fix, no
+warning was observed. Ran various vSocket tests without issues.
+
+Fixes: 06164d2b72aa ("VMCI: queue pairs implementation.")

+Subject: vxlan: move debug check after netdev unregister
+
+From: Taehee Yoo <ap420073@gmail.com>
+
+[ Upstream commit 92584ddf550ae72d492858c19d1f9025e07a9350 ]
+
+The debug check must be done after unregister_netdevice_many() call --
+the hlist_del_rcu() for this is done inside .ndo_stop.
+
+This is the same with commit 0fda7600c2e1 ("geneve: move debug check after
+netdev unregister")
+
+Test commands:
+ ip netns del A
+ ip netns add A
+ ip netns add B
+
+ ip netns exec B ip link add vxlan0 type vxlan vni 100 local 10.0.0.1 \
+ remote 10.0.0.2 dstport 4789 srcport 4789 4789
+ ip netns exec B ip link set vxlan0 netns A
+ ip netns exec A ip link set vxlan0 up
+ ip netns del B
+
+Splat looks like:

+Subject: xen/netback: fix spurious event detection for common event case
+
+From: Juergen Gross <jgross@suse.com>
+
+[ Upstream commit a3daf3d39132b405781be8d9ede0c449b244b64e ]
+
+In case of a common event for rx and tx queue the event should be
+regarded to be spurious if no rx and no tx requests are pending.
+
+Unfortunately the condition for testing that is wrong causing to
+decide a event being spurious if no rx OR no tx requests are
+pending.
+
+Fix that plus using local variables for rx/tx pending indicators in
+order to split function calls and if condition.
