+Subject: 6lowpan: Off by one handling ->nexthdr
+
+From: Dan Carpenter <dan.carpenter@oracle.com>
+
+[ Upstream commit f57c4bbf34439531adccd7d3a4ecc14f409c1399 ]
+
+NEXTHDR_MAX is 255. What happens here is that we take a u8 value
+"hdr->nexthdr" from the network and then look it up in
+lowpan_nexthdr_nhcs[]. The problem is that if hdr->nexthdr is 0xff then
+we read one element beyond the end of the array so the array needs to
+be one element larger.

+Subject: ALSA: usb-audio: update quirk for B&W PX to remove microphone
+
+From: Nicolas Huaman <nicolas@herochao.de>
+
+[ Upstream commit c369c8db15d51fa175d2ba85928f79d16af6b562 ]
+
+A quirk in snd-usb-audio was added to automate setting sample rate to
+4800k and remove the previously exposed nonfunctional microphone for
+the Bowers & Wilkins PX:
+commit 240a8af929c7c57dcde28682725b29cf8474e8e5
+https://lore.kernel.org/patchwork/patch/919689/
+
+However the headphones where updated shortly after that to remove the
+unintentional microphone functionality. I guess because of this the
+headphones now crash when connecting them via USB while the quirk is
+active. Dmesg:
+
+snd-usb-audio: probe of 2-3:1.0 failed with error -22
+usb 2-3: 2:1: cannot get min/max values for control 2 (id 2)
+
+This patch removes the microfone and allows the headphones to connect
+and work out of the box. It is based on the current mainline kernel
+ and successfully applied an tested on my machine (4.18.10.arch1-1).

+Subject: ARM: 8847/1: pm: fix HYP/SVC mode mismatch when MCPM is used
+
+From: Marek Szyprowski <m.szyprowski@samsung.com>
+
+[ Upstream commit ca70ea43f80c98582f5ffbbd1e6f4da2742da0c4 ]
+
+MCPM does a soft reset of the CPUs and uses common cpu_resume() routine to
+perform low-level platform initialization. This results in a try to install
+HYP stubs for the second time for each CPU and results in false HYP/SVC
+mode mismatch detection. The HYP stubs are already installed at the
+beginning of the kernel initialization on the boot CPU (head.S) or in the
+secondary_startup() for other CPUs. To fix this issue MCPM code should use
+a cpu_resume() routine without HYP stubs installation.
+
+This change fixes HYP/SVC mode mismatch on Samsung Exynos5422-based Odroid
+XU3/XU4/HC1 boards.

+Subject: ARM: dts: ls1021: Fix SGMII PCS link remaining down after PHY
+ disconnect
+
+From: Vladimir Oltean <olteanv@gmail.com>
+
+[ Upstream commit c7861adbe37f576931650ad8ef805e0c47564b9a ]
+
+Each eTSEC MAC has its own TBI (SGMII) PCS and private MDIO bus.
+But due to a DTS oversight, both SGMII-compatible MACs of the LS1021 SoC
+are pointing towards the same internal PCS. Therefore nobody is
+controlling the internal PCS of eTSEC0.
+
+Upon initial ndo_open, the SGMII link is ok by virtue of U-boot
+initialization. But upon an ifdown/ifup sequence, the code path from
+ndo_open -> init_phy -> gfar_configure_serdes does not get executed for
+the PCS of eTSEC0 (and is executed twice for MAC eTSEC1). So the SGMII
+link remains down for eTSEC0. On the LS1021A-TWR board, to signal this
+failure condition, the PHY driver keeps printing
+'803x_aneg_done: SGMII link is not ok'.
+
+Also, it changes compatible of mdio0 to "fsl,etsec2-mdio" to match
+mdio1 device.

+Subject: ARM: OMAP2+: Fix potentially uninitialized return value for
+ _setup_reset()
+
+From: Tony Lindgren <tony@atomide.com>
+
+[ Upstream commit 7f0d078667a494466991aa7133f49594f32ff6a2 ]
+
+Commit 747834ab8347 ("ARM: OMAP2+: hwmod: revise hardreset behavior") made
+the call to _enable() conditional based on no oh->rst_lines_cnt. This
+caused the return value to be potentially uninitialized. Curiously we see
+no compiler warnings for this, probably as this gets inlined.
+
+We call _setup_reset() from _setup() and only _setup_postsetup() if the
+return value is zero. Currently the return value can be uninitialized for
+cases where oh->rst_lines_cnt is set and HWMOD_INIT_NO_RESET is not set.

+Subject: arm64: dts: juno: Fix UART frequency
+
+From: Andre Przywara <andre.przywara@arm.com>
+
+[ Upstream commit 39a1a8941b27c37f79508426e27a2ec29829d66c ]
+
+Older versions of the Juno *SoC* TRM [1] recommended that the UART clock
+source should be 7.2738 MHz, whereas the *system* TRM [2] stated a more
+correct value of 7.3728 MHz. Somehow the wrong value managed to end up in
+our DT.
+
+Doing a prime factorisation, a modulo divide by 115200 and trying
+to buy a 7.2738 MHz crystal at your favourite electronics dealer suggest
+that the old value was actually a typo. The actual UART clock is driven
+by a PLL, configured via a parameter in some board.txt file in the
+firmware, which reads 7.37 MHz (sic!).
+
+Fix this to correct the baud rate divisor calculation on the Juno board.

+A stream may specify a rate range using 'rate_min' and 'rate_max', so a
+stream may be valid and not specify any rates. However, as stream cannot
+be valid and not have any channel. Let's use this condition instead to

+From: Brian Masney <masneyb@onstation.org>

+[ Upstream commit d3f48ec0954c6aac736ab21c34a35d7554409112 ]
+
+lm3630a_bank_a_update_status() and lm3630a_bank_b_update_status()
+both return the brightness value if the brightness was successfully
+updated. Writing to these attributes via sysfs would cause a 'Bad
+address' error to be returned. These functions should return 0 on
+success, so let's change it to correct that error.

+An earlier commit re-worked the setting of the bitmask and is now

+
+[ Upstream commit 1a67356e9a4829da2935dd338630a550c59c8489 ]
+
+It is wrong to use bio->bi_vcnt to figure out how many segments
+there are in the bio even though CLONED flag isn't set on this bio,
+because this bio may be splitted or advanced.
+
+So always use bio_segments() in blk_recount_segments(), and it shouldn't
+cause any performance loss now because the physical segment number is figured
+out in blk_queue_split() and BIO_SEG_VALID is set meantime since

+Subject: Btrfs: fix hang when loading existing inode cache off disk
+
+From: Filipe Manana <fdmanana@suse.com>
+
+[ Upstream commit 7764d56baa844d7f6206394f21a0e8c1f303c476 ]
+
+If we are able to load an existing inode cache off disk, we set the state
+of the cache to BTRFS_CACHE_FINISHED, but we don't wake up any one waiting
+for the cache to be available. This means that anyone waiting for the
+cache to be available, waiting on the condition that either its state is
+BTRFS_CACHE_FINISHED or its available free space is greather than zero,
+can hang forever.
+
+This could be observed running fstests with MOUNT_OPTIONS="-o inode_cache",
+in particular test case generic/161 triggered it very frequently for me,
+producing a trace like the following:
+

+If the clock tree is not fully populated when the timer-sun5i init code
+is called, attempts to get the clock rate for the timer would fail and
+return 0.
+
+Make the init code for both clock events and clocksource check the

+Subject: dmaengine: axi-dmac: Don't check the number of frames for alignment
+
+From: Alexandru Ardelean <alexandru.ardelean@analog.com>
+
+[ Upstream commit 648865a79d8ee3d1aa64aab5eb2a9d12eeed14f9 ]
+
+In 2D transfers (for the AXI DMAC), the number of frames (numf) represents
+Y_LENGTH, and the length of a frame is X_LENGTH. 2D transfers are useful
+for video transfers where screen resolutions ( X * Y ) are typically
+aligned for X, but not for Y.
+
+There is no requirement for Y_LENGTH to be aligned to the bus-width (or
+anything), and this is also true for AXI DMAC.
+
+Checking the Y_LENGTH for alignment causes false errors when initiating DMA
+transfers. This change fixes this by checking only that the Y_LENGTH is
+non-zero.

+
+Illegal memory will be touch if SDMA_SCRIPT_ADDRS_ARRAY_SIZE_V3

+ saddr_arr[i] = addr_arr[i]; /* memory corrupt here */
+That issue was brought by commit a572460be9cf ("dmaengine: imx-sdma: Add

+Using dma_dev->dev for mappings before it's assigned with the correct

+will at least make the current code operate as intended.

+
+From: Jon Hunter <jonathanh@nvidia.com>
+
+[ Upstream commit b53611fb1ce9b1786bd18205473e0c1d6bfa8934 ]
+
+Commit f33e7bb3eb92 ("dmaengine: tegra210-adma: restore channel status")
+added support to save and restore the DMA channel registers when runtime
+suspending the ADMA. This change is causing the kernel to crash when
+probing the ADMA, if the device is probed deferred when looking up the
+channel interrupts. The crash occurs because not all of the channel base
+addresses have been setup at this point and in the clean-up path of the
+probe, pm_runtime_suspend() is called invoking its callback which
+expects all the channel base addresses to be initialised.
+
+Although this could be fixed by simply checking for a NULL address, on
+further review of the driver it seems more appropriate that we only call
+pm_runtime_get_sync() after all the channel interrupts and base
+addresses have been configured. Therefore, fix this crash by moving the
+calls to pm_runtime_enable(), pm_runtime_get_sync() and
+tegra_adma_init() after the DMA channels have been initialised.

+Subject: dmaengine: tegra210-adma: restore channel status
+
+From: Sameer Pujar <spujar@nvidia.com>
+
+[ Upstream commit f33e7bb3eb922618612a90f0a828c790e8880773 ]
+
+Status of ADMA channel registers is not saved and restored during system
+suspend. During active playback if system enters suspend, this results in
+wrong state of channel registers during system resume and playback fails
+to resume properly. Fix this by saving following channel registers in
+runtime suspend and restore during runtime resume.
+ * ADMA_CH_LOWER_SRC_ADDR
+ * ADMA_CH_LOWER_TRG_ADDR
+ * ADMA_CH_FIFO_CTRL
+ * ADMA_CH_CONFIG
+ * ADMA_CH_CTRL
+ * ADMA_CH_CMD
+ * ADMA_CH_TC
+Runtime PM calls will be inovked during system resume path if a playback
+or capture needs to be resumed. Hence above changes work fine for system
+suspend case.

+Subject: drm/dp_mst: Skip validating ports during destruction, just ref
+
+From: Lyude Paul <lyude@redhat.com>
+
+[ Upstream commit c54c7374ff44de5e609506aca7c0deae4703b6d1 ]
+
+Jerry Zuo pointed out a rather obscure hotplugging issue that it seems I
+accidentally introduced into DRM two years ago.
+
+Pretend we have a topology like this:
+
+|- DP-1: mst_primary
+ |- DP-4: active display
+ |- DP-5: disconnected
+ |- DP-6: active hub
+ |- DP-7: active display
+ |- DP-8: disconnected
+ |- DP-9: disconnected
+
+If we unplug DP-6, the topology starting at DP-7 will be destroyed but
+it's payloads will live on in DP-1's VCPI allocations and thus require
+removal. However, this removal currently fails because
+drm_dp_update_payload_part1() will (rightly so) try to validate the port
+before accessing it, fail then abort. If we keep going, eventually we
+run the MST hub out of bandwidth and all new allocations will start to
+fail (or in my case; all new displays just start flickering a ton).
+
+We could just teach drm_dp_update_payload_part1() not to drop the port
+ref in this case, but then we also need to teach
+drm_dp_destroy_payload_step1() to do the same thing, then hope no one
+ever adds anything to the that requires a validated port reference in
+drm_dp_destroy_connector_work(). Kind of sketchy.
+
+So let's go with a more clever solution: any port that
+drm_dp_destroy_connector_work() interacts with is guaranteed to still
+exist in memory until we say so. While said port might not be valid we
+don't really care: that's the whole reason we're destroying it in the
+first place! So, teach drm_dp_get_validated_port_ref() to use the all
+mighty current_work() function to avoid attempting to validate ports
+from the context of mgr->destroy_connector_work. I can't see any
+situation where this wouldn't be safe, and this avoids having to play
+whack-a-mole in the future of trying to work around port validation.

+Subject: drm/msm/dsi: Implement reset correctly
+
+From: Jeffrey Hugo <jeffrey.l.hugo@gmail.com>
+
+[ Upstream commit 78e31c42261779a01bc73472d0f65f15378e9de3 ]
+
+On msm8998, vblank timeouts are observed because the DSI controller is not
+reset properly, which ends up stalling the MDP. This is because the reset
+logic is not correct per the hardware documentation.
+
+The documentation states that after asserting reset, software should wait
+some time (no indication of how long), or poll the status register until it
+returns 0 before deasserting reset.
+
+wmb() is insufficient for this purpose since it just ensures ordering, not
+timing between writes. Since asserting and deasserting reset occurs on the
+same register, ordering is already guaranteed by the architecture, making
+the wmb extraneous.
+
+Since we would define a timeout for polling the status register to avoid a
+possible infinite loop, lets just use a static delay of 20 ms, since 16.666
+ms is the time available to process one frame at 60 fps.

+
+[ Upstream commit fc19cbb785d7bbd1a1af26229b5240a3ab332744 ]
+
+If mdp5_cfg_init fails because of an unknown major version, a null pointer

+From: Sam Bobroff <sbobroff@linux.ibm.com>
+
+[ Upstream commit 62d91dd2851e8ae2ca552f1b090a3575a4edf759 ]
+
+The INTERRUPT_CNTL2 register expects a valid DMA address, but is
+currently set with a GPU MC address. This can cause problems on
+systems that detect the resulting DMA read from an invalid address
+(found on a Power8 guest).
+
+Instead, use the DMA address of the dummy page because it will always
+be safe.

+
+[ Upstream commit 66e31a72dc38543b2d9d1ce267dc78ba9beebcfd ]
+
+Removing the drm_bridge_remove call should avoid a NULL dereference
+during list processing in drm_bridge_remove if the error path is ever
+taken.
+
+The more natural approach would perhaps be to add a drm_bridge_add,
+but there are several other bridges that never call drm_bridge_add.
+Just removing the drm_bridge_remove is the easier fix.

+
+First, we read from "vgdev->capsets[idx].max_size" before checking

+From: Guenter Roeck <linux@roeck-us.net>
+
+[ Upstream commit 7d82fcc9d9e81241778aaa22fda7be753e237d86 ]
+
+Writes into limit registers fail if the temperature written is negative.
+The regmap write operation checks the value range, regmap_write accepts
+an unsigned int as parameter, and the temperature value passed to
+regmap_write is kept in a variable declared as long. Negative values
+are converted large unsigned integers, which fails the range check.
+Fix by type casting the temperature to u16 when calling regmap_write().

+
+The QP transition optional parameters for the various transition for XRC
+QPs are identical to those for RC QPs.
+
+Many of the XRC QP transition optional parameter bits are missing from the

+For example, when trying to change the response timer of an XRC receive QP
+via the RTS2RTS transition, the new timer value was ignored because
+MLX5_QP_OPTPAR_RNR_TIMEOUT bit was missing from the optional params mask
+for XRC qps for the RTS2RTS transition.
+
+Fix this by adding the missing XRC optional parameters for all QP
+transitions to the opt_mask table.

+Subject: inet: frags: call inet_frags_fini() after unregister_pernet_subsys()

+From: Eric Dumazet <edumazet@google.com>
+
+[ Upstream commit ae7352d384a552d8c799c242e74a934809990a71 ]
+
+Both IPv6 and 6lowpan are calling inet_frags_fini() too soon.
+
+inet_frags_fini() is dismantling a kmem_cache, that might be needed
+later when unregister_pernet_subsys() eventually has to remove
+frags queues from hash tables and free them.
+
+This fixes potential use-after-free, and is a prereq for the following patch.

+Subject: iw_cxgb4: use tos when finding ipv6 routes
+
+From: Steve Wise <swise@opengridcomputing.com>
+
+[ Upstream commit c8a7eb554a83214c3d8ee5cb322da8c72810d2dc ]
+
+When IPv6 support was added, the correct tos was not passed to
+cxgb_find_route6(). This potentially results in the wrong route entry.

+Subject: iwlwifi: mvm: fix A-MPDU reference assignment
+
+From: Johannes Berg <johannes.berg@intel.com>
+
+[ Upstream commit 1f7698abedeeb3fef3cbcf78e16f925df675a179 ]
+
+The current code assigns the reference, and then goes to increment
+it if the toggle bit has changed. That way, we get
+
+Toggle 0 0 0 0 1 1 1 1
+ID 1 1 1 1 1 2 2 2
+
+Fix that by assigning the post-toggle ID to get
+
+Toggle 0 0 0 0 1 1 1 1
+ID 1 1 1 1 2 2 2 2

+
+[ Upstream commit a5fdd713d256887b5f012608701149fa939e5645 ]

+A statement was originally added in 2006 to shut up a gcc warning,
+now but now clang warns about it:

+Modern versions of gcc are fine without the silly assignment, so just
+drop it. Tested with gcc-4.6 (released 2011), 4.7, 4.8, and 4.9.

+Subject: libertas_tf: Use correct channel range in lbtf_geo_init
+
+From: YueHaibing <yuehaibing@huawei.com>
+
+[ Upstream commit 2ec4ad49b98e4a14147d04f914717135eca7c8b1 ]
+
+It seems we should use 'range' instead of 'priv->range'
+in lbtf_geo_init(), because 'range' is the corret one
+related to current regioncode.

+Subject: llc: fix sk_buff refcounting in llc_conn_state_process()
+
+From: Eric Biggers <ebiggers@google.com>
+
+[ Upstream commit 36453c852816f19947ca482a595dffdd2efa4965 ]
+
+If llc_conn_state_process() sees that llc_conn_service() put the skb on
+a list, it will drop one fewer references to it. This is wrong because
+the current behavior is that llc_conn_service() never consumes a
+reference to the skb.
+
+The code also makes the number of skb references being dropped
+conditional on which of ind_prim and cfm_prim are nonzero, yet neither
+of these affects how many references are *acquired*. So there is extra
+code that tries to fix this up by sometimes taking another reference.
+
+Remove the unnecessary/broken refcounting logic and instead just add an
+skb_get() before the only two places where an extra reference is
+actually consumed.

+Subject: m68k: Call timer_interrupt() with interrupts disabled
+
+From: Finn Thain <fthain@telegraphics.com.au>
+
+[ Upstream commit 1efdd4bd254311498123a15fa0acd565f454da97 ]
+
+Some platforms execute their timer handler with the interrupt priority
+level set below 6. That means the handler could be interrupted by another
+driver and this could lead to re-entry of the timer core.
+
+Avoid this by use of local_irq_save/restore for timer interrupt dispatch.
+This provides mutual exclusion around the timer interrupt flag access
+which is needed later in this series for the clocksource conversion.

+
+[ Upstream commit 0ca7ce7db771580433bf24454f7a1542bd326078 ]

+This resolves some bugs that affect VIA timer counter accesses.
+Avoid lost interrupts caused by reading the counter low byte register.
+Make allowance for the fact that the counter will be decremented to
+0xFFFF before being reloaded.

+Subject: media: davinci-isif: avoid uninitialized variable use
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+[ Upstream commit 0e633f97162c1c74c68e2eb20bbd9259dce87cd9 ]
+
+clang warns about a possible variable use that gcc never
+complained about:
+
+drivers/media/platform/davinci/isif.c:982:32: error: variable 'frame_size' is uninitialized when used here
+ [-Werror,-Wuninitialized]
+ dm365_vpss_set_pg_frame_size(frame_size);
+ ^~~~~~~~~~
+drivers/media/platform/davinci/isif.c:887:2: note: variable 'frame_size' is declared here
+ struct vpss_pg_frame_size frame_size;
+ ^
+1 error generated.
+
+There is no initialization for this variable at all, and there
+has never been one in the mainline kernel, so we really should
+not put that stack data into an mmio register.
+
+On the other hand, I suspect that gcc checks the condition
+more closely and notices that the global
+isif_cfg.bayer.config_params.test_pat_gen flag is initialized
+to zero and never written to from any code path, so anything
+depending on it can be eliminated.
+
+To shut up the clang warning, just remove the dead code manually,
+it has probably never been used because any attempt to do so
+would have resulted in undefined behavior.

+
+From: Dan Carpenter <dan.carpenter@oracle.com>
+
+[ Upstream commit dd6e2a981bfe83aa4a493143fd8cf1edcda6c091 ]
+
+The "b->index" is a u32 the comes from the user in the ioctl. It hasn't
+been checked. We aren't supposed to use it but we're instead supposed
+to use the value that gets written to it when we call videobuf_dqbuf().
+
+The videobuf_dqbuf() first memsets it to zero and then re-initializes it
+inside the videobuf_status() function. It's this final value which we
+want.
+
+Hans Verkuil pointed out that we need to check the return from
+videobuf_dqbuf(). I ended up doing a little cleanup related to that as
+well.

+Subject: media: ov6650: Fix .get_fmt() V4L2_SUBDEV_FORMAT_TRY support
+
+From: Janusz Krzysztofik <jmkrzyszt@gmail.com>
+
+[ Upstream commit 39034bb0c26b76a2c3abc54aa28c185f18b40c2f ]
+
+Commit da298c6d98d5 ("[media] v4l2: replace video op g_mbus_fmt by pad
+op get_fmt") converted a former ov6650_g_fmt() video operation callback
+to an ov6650_get_fmt() pad operation callback. However, the converted
+function disregards a format->which flag that pad operations should
+obey and always returns active frame format settings.
+
+That can be fixed by always responding to V4L2_SUBDEV_FORMAT_TRY with
+-EINVAL, or providing the response from a pad config argument, likely
+updated by a former user call to V4L2_SUBDEV_FORMAT_TRY .set_fmt().
+Since implementation of the latter is trivial, go for it.

+[ Upstream commit 1c6a2b63095154bbf9e8f38d79487a728331bf65 ]
+
+User arguments passed to .get/set_fmt() pad operation callbacks may
+contain unsupported values. The driver takes control over frame size
+and pixel code as well as colorspace and field attributes but has never
+cared for remainig format attributes, i.e., ycbcr_enc, quantization
+and xfer_func, introduced by commit 11ff030c7365 ("[media]
+v4l2-mediabus: improve colorspace support"). Fix it.
+
+Set up a static v4l2_mbus_framefmt structure with attributes
+initialized to reasonable defaults and use it for updating content of
+user provided arguments. In case of V4L2_SUBDEV_FORMAT_ACTIVE,
+postpone frame size update, now performed from inside ov6650_s_fmt()
+helper, util the user argument is first updated in ov6650_set_fmt() with
+default frame format content. For V4L2_SUBDEV_FORMAT_TRY, don't copy
+all attributes to pad config, only those handled by the driver, then
+fill the response with the default frame format updated with resulting
+pad config format code and frame size.

+
+[ Upstream commit 19c624c6b29e244c418f8b44a711cbf5e82e3cd4 ]
+
+This commit corrects max and step values for v4l2 control for
+V4L2_CID_JPEG_RESTART_INTERVAL. Max should be 0xffff and step should be 1.
+It was found by using v4l2-compliance tool and checking result of
+VIDIOC_QUERY_EXT_CTRL/QUERYMENU test.
+Previously it was complaining that step was bigger than difference
+between max and min.

+Subject: mic: avoid statically declaring a 'struct device'.
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+[ Upstream commit bc83f79bd2119230888fb8574639d5a51b38f903 ]
+
+Generally, declaring a platform device as a static variable is
+a bad idea and can cause all kinds of problems, in particular
+with the DMA configuration and lifetime rules.
+
+A specific problem we hit here is from a bug in clang that warns
+about certain (otherwise valid) macros when used in static variables:
+
+drivers/misc/mic/card/mic_x100.c:285:27: warning: shift count >= width of type [-Wshift-count-overflow]
+static u64 mic_dma_mask = DMA_BIT_MASK(64);
+ ^~~~~~~~~~~~~~~~
+include/linux/dma-mapping.h:141:54: note: expanded from macro 'DMA_BIT_MASK'
+ #define DMA_BIT_MASK(n) (((n) == 64) ? ~0ULL : ((1ULL<<(n))-1))
+ ^ ~~~
+
+A slightly better way here is to create the platform device dynamically
+and set the dma mask in the probe function.
+This avoids the warning and some other problems, but is still not ideal
+because the device creation should really be separated from the driver,
+and the fact that the device has no parent means we have to force
+the dma mask rather than having it set up from the bus that the device
+is actually on.

+Subject: mips: avoid explicit UB in assignment of mips_io_port_base
+
+From: Nick Desaulniers <ndesaulniers@google.com>
+
+[ Upstream commit 12051b318bc3ce5b42d6d786191008284b067d83 ]
+
+The code in question is modifying a variable declared const through
+pointer manipulation. Such code is explicitly undefined behavior, and
+is the lone issue preventing malta_defconfig from booting when built
+with Clang:
+
+If an attempt is made to modify an object defined with a const-qualified
+type through use of an lvalue with non-const-qualified type, the
+behavior is undefined.
+
+LLVM is removing such assignments. A simple fix is to not declare
+variables const that you plan on modifying. Limiting the scope would be
+a better method of preventing unwanted writes to such a variable.
+
+Further, the code in question mentions "compiler bugs" without any links
+to bug reports, so it is difficult to know if the issue is resolved in
+GCC. The patch was authored in 2006, which would have been GCC 4.0.3 or
+4.1.1. The minimal supported version of GCC in the Linux kernel is
+currently 4.6.
+
+For what its worth, there was UB before the commit in question, it just
+added a barrier and got lucky IRT codegen. I don't think there's any
+actual compiler bugs related, just runtime bugs due to UB.

+Subject: misc: sgi-xp: Properly initialize buf in xpc_get_rsvd_page_pa
+
+From: Nathan Chancellor <natechancellor@gmail.com>
+
+[ Upstream commit b0576f9ecb5c51e9932531d23c447b2739261841 ]
+
+Clang warns:
+
+drivers/misc/sgi-xp/xpc_partition.c:73:14: warning: variable 'buf' is
+uninitialized when used within its own initialization [-Wuninitialized]
+ void *buf = buf;
+ ~~~ ^~~
+1 warning generated.
+
+Arnd's explanation during review:
+
+ /*
+ * Returns the physical address of the partition's reserved page through
+ * an iterative number of calls.
+ *
+ * On first call, 'cookie' and 'len' should be set to 0, and 'addr'
+ * set to the nasid of the partition whose reserved page's address is
+ * being sought.
+ * On subsequent calls, pass the values, that were passed back on the
+ * previous call.
+ *
+ * While the return status equals SALRET_MORE_PASSES, keep calling
+ * this function after first copying 'len' bytes starting at 'addr'
+ * into 'buf'. Once the return status equals SALRET_OK, 'addr' will
+ * be the physical address of the partition's reserved page. If the
+ * return status equals neither of these, an error as occurred.
+ */
+ static inline s64
+ sn_partition_reserved_page_pa(u64 buf, u64 *cookie, u64 *addr, u64 *len)
+
+ so *len is set to zero on the first call and tells the bios how many
+ bytes are accessible at 'buf', and it does get updated by the BIOS to
+ tell us how many bytes it needs, and then we allocate that and try again.
+

+From: Petr Machata <petrm@mellanox.com>

+Add QEEC.mise (minimum shaper enable) and QEEC.min_shaper_rate to enable

+
+Increase the QEEC length to 0x20 as well: that's the length that the

+
+From: Sameeh Jubran <sameehj@amazon.com>
+
+[ Upstream commit b287cdbd1cedfc9606682c6e02b58d00ff3a33ae ]
+
+ena_up() calls ena_init_napi() but does not call ena_del_napi() in
+case of failure. This causes a segmentation fault upon rmmod when
+netif_napi_del() is called. Fix this bug by calling ena_del_napi()
+before returning error from ena_up().

+
+[ Upstream commit 177b8007463c4f36c9a2c7ce7aa9875a4cad9bd5 ]
+
+When GSO frame has to be corrupted netem uses skb_gso_segment()
+to produce the list of frames, and re-enqueues the segments one
+by one. The backlog length has to be adjusted to account for
+new frames.
+
+The current calculation is incorrect, leading to wrong backlog
+lengths in the parent qdisc (both bytes and packets), and
+incorrect packet backlog count in netem itself.
+
+Parent backlog goes negative, netem's packet backlog counts
+all non-first segments twice (thus remaining non-zero even
+after qdisc is emptied).
+
+Move the variables used to count the adjustment into local
+scope to make 100% sure they aren't used at any stage in
+backports.

+Subject: net: netem: fix error path for corrupted GSO frames
+
+From: Jakub Kicinski <jakub.kicinski@netronome.com>
+
+[ Upstream commit a7fa12d15855904aff1716e1fc723c03ba38c5cc ]
+
+To corrupt a GSO frame we first perform segmentation. We then
+proceed using the first segment instead of the full GSO skb and
+requeue the rest of the segments as separate packets.
+
+If there are any issues with processing the first segment we
+still want to process the rest, therefore we jump to the
+finish_segs label.
+
+Commit 177b8007463c ("net: netem: fix backlog accounting for
+corrupted GSO frames") started using the pointer to the first
+segment in the "rest of segments processing", but as mentioned
+above the first segment may had already been freed at this point.
+
+Backlog corrections for parent qdiscs have to be adjusted.

+Subject: net: stmmac: fix length of PTP clock's name string
+
+From: Antonio Borneo <antonio.borneo@st.com>
+
+[ Upstream commit 5da202c88f8c355ad79bc2e8eb582e6d433060e7 ]
+
+The field "name" in struct ptp_clock_info has a fixed size of 16
+chars and is used as zero terminated string by clock_name_show()
+in drivers/ptp/ptp_sysfs.c
+The current initialization value requires 17 chars to fit also the
+null termination, and this causes overflow to the next bytes in
+the struct when the string is read as null terminated:
+ hexdump -C /sys/class/ptp/ptp0/clock_name
+ 00000000 73 74 6d 6d 61 63 5f 70 74 70 5f 63 6c 6f 63 6b |stmmac_ptp_clock|
+ 00000010 a0 ac b9 03 0a |.....|
+where the extra 4 bytes (excluding the newline) after the string
+represent the integer 0x03b9aca0 = 62500000 assigned to the field
+"max_adj" that follows "name" in the same struct.
+
+There is no strict requirement for the "name" content and in the
+comment in ptp_clock_kernel.h it's reported it should just be 'A
+short "friendly name" to identify the clock'.
+Replace it with "stmmac ptp".

+Fix a soft lockup when NFS client delegation recovery is attempted
+but the inode is in the process of being freed. When the

+Subject: nvme: retain split access workaround for capability reads
+
+From: Ard Biesheuvel <ard.biesheuvel@linaro.org>
+
+[ Upstream commit 3a8ecc935efabdad106b5e06d07b150c394b4465 ]
+
+Commit 7fd8930f26be4
+
+ "nvme: add a common helper to read Identify Controller data"
+
+has re-introduced an issue that we have attempted to work around in the
+past, in commit a310acd7a7ea ("NVMe: use split lo_hi_{read,write}q").
+
+The problem is that some PCIe NVMe controllers do not implement 64-bit
+outbound accesses correctly, which is why the commit above switched
+to using lo_hi_[read|write]q for all 64-bit BAR accesses occuring in
+the code.
+
+In the mean time, the NVMe subsystem has been refactored, and now calls
+into the PCIe support layer for NVMe via a .reg_read64() method, which
+fails to use lo_hi_readq(), and thus reintroduces the problem that the
+workaround above aimed to address.
+
+Given that, at the moment, .reg_read64() is only used to read the
+capability register [which is known to tolerate split reads], let's
+switch .reg_read64() to lo_hi_readq() as well.
+
+This fixes a boot issue on some ARM boxes with NVMe behind a Synopsys
+DesignWare PCIe host controller.

+Adding a couple of READ_ONCE()/WRITE_ONCE() should silence it.

+Subject: packet: in recvmsg msg_name return at least sizeof sockaddr_ll
+
+From: Willem de Bruijn <willemb@google.com>
+
+[ Upstream commit b2cf86e1563e33a14a1c69b3e508d15dc12f804c ]
+
+Packet send checks that msg_name is at least sizeof sockaddr_ll.
+Packet recv must return at least this length, so that its output
+can be passed unmodified to packet send.
+
+This ceased to be true since adding support for lladdr longer than
+sll_addr. Since, the return value uses true address length.
+
+Always return at least sizeof sockaddr_ll, even if address length
+is shorter. Zero the padding bytes.
+
+Change v1->v2: do not overwrite zeroed padding again. use copy_len.
+
+Fixes: 0fb375fb9b93 ("[AF_PACKET]: Allow for > 8 byte hardware addresses.")

+Subject: Partially revert "kfifo: fix kfifo_alloc() and kfifo_init()"
+
+From: Linus Torvalds <torvalds@linux-foundation.org>
+
+[ Upstream commit ab9bb6318b0967671e0c9b6537c1537d51ca4f45 ]
+
+Commit dfe2a77fd243 ("kfifo: fix kfifo_alloc() and kfifo_init()") made
+the kfifo code round the number of elements up. That was good for
+__kfifo_alloc(), but it's actually wrong for __kfifo_init().
+
+The difference? __kfifo_alloc() will allocate the rounded-up number of
+elements, but __kfifo_init() uses an allocation done by the caller. We
+can't just say "use more elements than the caller allocated", and have
+to round down.
+
+The good news? All the normal cases will be using power-of-two arrays
+anyway, and most users of kfifo's don't use kfifo_init() at all, but one
+of the helper macros to declare a KFIFO that enforce the proper
+power-of-two behavior. But it looks like at least ibmvscsis might be
+affected.
+
+The bad news? Will Deacon refers to an old thread and points points out
+that the memory ordering in kfifo's is questionable. See
+
+ https://lore.kernel.org/lkml/20181211034032.32338-1-yuleixzhang@tencent.com/
+
+for more.

+[ Upstream commit b1e3874c75ab15288f573b3532e507c37e8e7656 ]
+
+Passing string 'name' as the format specifier is potentially hazardous
+because name could (although very unlikely to) have a format specifier
+embedded in it causing issues when parsing the non-existent arguments
+to these. Follow best practice by using the "%s" format string for
+the string 'name'.

+
+From: Geert Uytterhoeven <geert+renesas@glider.be>
+
+[ Upstream commit 0d6256cb880166a4111bebce35790019e56b6e1b ]
+
+The vin1_b_data18_mux[] arrays contains pin marks for the 2 LSB bits of
+the color components. The vin1_b_data18_pins[] array rightfully does
+not include the corresponding pin numbers, as RGB18 is subset of RGB24,
+containing only the 6 MSB bits of each component.

+
+From: Stephen Boyd <swboyd@chromium.org>
+
+[ Upstream commit 8288022284859acbcc3cf1a073a1e2692d6c2543 ]
+
+We may want to use the device pointer in device_init_wakeup() with
+functions that expect the device to already be added with device_add().
+For example, if we were to link the device initializing wakeup to
+something in sysfs such as a class for wakeups we'll run into an error.
+It looks like this code was written with the assumption that the device
+would be added before initializing wakeup due to the order of operations
+in power_supply_unregister().
+
+Let's change the order of operations so we don't run into problems here.

+From: Nathan Lynch <nathanl@linux.ibm.com>
+
+[ Upstream commit d4aa219a074a5abaf95a756b9f0d190b5c03a945 ]
+
+Allow external callers to force the cacheinfo code to release all its
+references to cache nodes, e.g. before processing device tree updates
+post-migration, and to rebuild the hierarchy afterward.
+
+CPU online/offline must be blocked by callers; enforce this.

+clang warns about an overly large stack frame in one function
+when it decides to inline all __qed_get_vport_*() functions into
+__qed_get_vport_stats():

+drivers/net/ethernet/qlogic/qed/qed_l2.c:1889:13: error: stack frame size of 1128 bytes in function '_qed_get_vport_stats' [-Werror,-Wframe-larger-than=]

+
+From: Xi Wang <wangxi11@huawei.com>
+
+[ Upstream commit ec5bc2cc69b4fc494e04d10fc5226f6f9cf67c56 ]
+
+When smmu is enable, if execute the perftest command and then use 'kill
+-9' to exit, follow this operation repeatedly, the kernel will have a high
+probability to print the following smmu event:
+
+ arm-smmu-v3 arm-smmu-v3.1.auto: event 0x10 received:
+ arm-smmu-v3 arm-smmu-v3.1.auto: 0x00007d0000000010

+ arm-smmu-v3 arm-smmu-v3.1.auto: 0x00000000f47cf000
+
+This is because the hw will periodically refresh the qpc cache until the
+next reset.
+
+This patch fixed it by removing the action that release qpc memory in the
+'hns_roce_qp_free' function.

+
+[ Upstream commit 28be5f15df2ee6882b0a122693159c96a28203c7 ]
+
+commit efdfeb079cc3
+("regulator: fixed: Convert to use GPIO descriptor only")
+switched to use gpiod_get() to look up the regulator from the
+gpiolib core whether that is device tree or boardfile.
+
+This meant that we activate the code in
+a603a2b8d86e ("gpio: of: Add special quirk to parse regulator flags")
+which means the descriptors coming from the device tree already
+have the right inversion and open drain semantics set up from
+the gpiolib core.
+
+As the fixed regulator was inspected again we got the
+inverted inversion and things broke.
+
+Fix it by ignoring the config in the device tree for now: the
+later patches in the series will push all inversion handling
+over to the gpiolib core and set it up properly in the
+boardfiles for legacy devices, but I did not finish that
+for this kernel cycle.

+Subject: rtc: cmos: ignore bogus century byte
+
+From: Eric Wong <e@80x24.org>
+
+[ Upstream commit 2a4daadd4d3e507138f8937926e6a4df49c6bfdc ]
+
+Older versions of Libreboot and Coreboot had an invalid value
+(`3' in my case) in the century byte affecting the GM45 in
+the Thinkpad X200. Not everybody's updated their firmwares,
+and Linux <= 4.2 was able to read the RTC without problems,
+so workaround this by ignoring invalid values.

+Shifting a u8 by 24 will cause the value to be promoted to an integer. If

+
+From: Chen-Yu Tsai <wens@csie.org>
+
+[ Upstream commit 3572e8aea3bf925dac1dbf86127657c39fe5c254 ]
+
+Besides the alarm, the PCF8563 also has a timer triggered interrupt.
+In cases where the previous system left the timer and interrupts on,
+or somehow the bits got enabled, the interrupt would keep triggering
+as the kernel doesn't know about it.
+
+Clear both the alarm and timer event flags, and disable the interrupts,
+before requesting the interrupt line.

+
+From: Steve Sistare <steven.sistare@oracle.com>
+
+[ Upstream commit 31b6a05f86e690e1818116fd23c3be915cc9d9ed ]
+
+megaraid_sas takes 1+ seconds to load while waiting for firmware:
+
+[2.822603] megaraid_sas 0000:03:00.0: Waiting for FW to come to ready state
+[3.871003] megaraid_sas 0000:03:00.0: FW now in Ready state
+
+This is due to the following loop in megasas_transition_to_ready(), which
+waits a minimum of 1 second, even though the FW becomes ready in tens of
+millisecs:
+
+ /*
+ * The cur_state should not last for more than max_wait secs
+ */
+ for (i = 0; i < max_wait; i++) {
+ ...
+ msleep(1000);
+ ...
+ dev_info(&instance->pdev->dev, "FW now in Ready state\n");
+
+This is a regression, caused by a change of the msleep granularity from 1
+to 1000 due to concern about waiting too long on systems with coarse
+jiffies.
+
+To fix, increase iterations and use msleep(20), which results in:
+
+[2.670627] megaraid_sas 0000:03:00.0: Waiting for FW to come to ready state

+Subject: signal: Allow cifs and drbd to receive their terminating signals
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Eric W. Biederman <ebiederm@xmission.com>
+
+[ Upstream commit 33da8e7c814f77310250bb54a9db36a44c5de784 ]
+
+My recent to change to only use force_sig for a synchronous events
+wound up breaking signal reception cifs and drbd. I had overlooked
+the fact that by default kthreads start out with all signals set to
+SIG_IGN. So a change I thought was safe turned out to have made it
+impossible for those kernel thread to catch their signals.
+
+Reverting the work on force_sig is a bad idea because what the code
+was doing was very much a misuse of force_sig. As the way force_sig
+ultimately allowed the signal to happen was to change the signal
+handler to SIG_DFL. Which after the first signal will allow userspace
+to send signals to these kernel threads. At least for
+wake_ack_receiver in drbd that does not appear actively wrong.
+
+So correct this problem by adding allow_kernel_signal that will allow
+signals whose siginfo reports they were sent by the kernel through,
+but will not allow userspace generated signals, and update cifs and
+drbd to call allow_kernel_signal in an appropriate place so that their
+thread can receive this signal.
+
+Fixing things this way ensures that userspace won't be able to send
+signals and cause problems, that it is clear which signals the
+threads are expecting to receive, and it guarantees that nothing
+else in the system will be affected.
+
+This change was partly inspired by similar cifs and drbd patches that
+added allow_signal.

+Subject: signal/cifs: Fix cifs_put_tcp_session to call send_sig instead of
+ force_sig
+
+From: Eric W. Biederman <ebiederm@xmission.com>
+
+[ Upstream commit 72abe3bcf0911d69b46c1e8bdb5612675e0ac42c ]
+
+The locking in force_sig_info is not prepared to deal with a task that
+exits or execs (as sighand may change). The is not a locking problem
+in force_sig as force_sig is only built to handle synchronous
+exceptions.
+
+Further the function force_sig_info changes the signal state if the
+signal is ignored, or blocked or if SIGNAL_UNKILLABLE will prevent the
+delivery of the signal. The signal SIGKILL can not be ignored and can
+not be blocked and SIGNAL_UNKILLABLE won't prevent it from being
+delivered.
+
+So using force_sig rather than send_sig for SIGKILL is confusing
+and pointless.
+
+Because it won't impact the sending of the signal and and because
+using force_sig is wrong, replace force_sig with send_sig.

+Subject: spi: bcm2835aux: fix driver to not allow 65535 (=-1) cs-gpios
+
+From: Martin Sperl <kernel@martin.sperl.org>
+
+[ Upstream commit 509c583620e9053e43d611bf1614fc3d3abafa96 ]
+
+The original driver by default defines num_chipselects as -1.
+This actually allicates an array of 65535 entries in
+of_spi_register_master.
+
+There is a side-effect for buggy device trees that (contrary to
+dt-binding documentation) have no cs-gpio defined.
+
+This mode was never supported by the driver due to limitations
+of native cs and additional code complexity and is explicitly
+not stated to be implemented.
+
+To keep backwards compatibility with such buggy DTs we limit
+the number of chip_selects to 1, as for all practical purposes
+it is only ever realistic to use a single chip select in
+native cs mode without negative side-effects.

+
+From: Sowjanya Komatineni <skomatineni@nvidia.com>
+
+[ Upstream commit 1a89ac5b91895127f7c586ec5075c3753ca25501 ]
+
+Fixes: computation of actual bytes to fill/receive in/from FIFO in unpacked
+mode when transfer length is not a multiple of requested bits per word.
+
+unpacked mode transfers fails when the transfer includes partial bytes in
+the last word.
+
+Total words to be written/read to/from FIFO is computed based on transfer
+length and bits per word. Unpacked mode includes 0 padding bytes for partial
+words to align with bits per word and these extra bytes are also accounted
+for calculating bytes left to transfer in the current driver.
+
+This causes extra bytes access of tx/rx buffers along with buffer index
+position crossing actual length where remain_len becomes negative and due to
+unsigned type, negative value is a 32 bit representation of signed value
+and transferred bytes never meets the actual transfer length resulting in
+transfer timeout and a hang.
+
+This patch fixes this with proper computation of the actual bytes to fill in
+FIFO during transmit and the actual bytes to read from FIFO during receive
+ignoring 0 padded bytes.

+
+From: Spencer E. Olson <olsonse@umich.edu>
+
+[ Upstream commit 1cbca5852d6c16e85a21487a15d211195aacd4a1 ]
+
+Fixes two problems introduced as early as
+commit 03aef4b6dc12 ("Staging: comedi: add ni_mio_common code"):
+(1) Ensures that the last four bits of NISTC_RTSI_TRIGB_OUT_REG register is
+ not unduly overwritten on e-series devices. On e-series devices, the
+ first three of the last four bits are reserved. The last bit defines
+ the output selection of the RGOUT0 pin, otherwise known as
+ RTSI_Sub_Selection. For m-series devices, these last four bits are
+ indeed used as the output selection of the RTSI7 pin (and the
+ RTSI_Sub_Selection bit for the RGOUT0 pin is moved to the
+ RTSI_Trig_Direction register.
+(2) Allows all 4 RTSI_BRD lines to be treated as valid sources for RTSI
+ lines.
+
+This patch also cleans up the ni_get_rtsi_routing command for readability.

+Subject: staging: greybus: light: fix a couple double frees
+
+From: Dan Carpenter <dan.carpenter@oracle.com>
+
+[ Upstream commit 329101244f214952606359d254ae883b7109e1a5 ]
+
+The problem is in gb_lights_request_handler(). If we get a request to
+change the config then we release the light with gb_lights_light_release()
+and re-allocated it. However, if the allocation fails part way through
+then we call gb_lights_light_release() again. This can lead to a couple
+different double frees where we haven't cleared out the original values:
+
+ gb_lights_light_v4l2_unregister(light);
+ ...
+ kfree(light->channels);
+ kfree(light->name);
+
+I also made a small change to how we set "light->channels_count = 0;".
+The original code handled this part fine and did not cause a use after
+free but it was sort of complicated to read.

+Subject: thermal: cpu_cooling: Actually trace CPU load in

+
+From: Matthias Kaehlcke <mka@chromium.org>
+
+[ Upstream commit bf45ac18b78038e43af3c1a273cae4ab5704d2ce ]
+
+The CPU load values passed to the thermal_power_cpu_get_power
+tracepoint are zero for all CPUs, unless, unless the
+thermal_power_cpu_limit tracepoint is enabled too:
+
+ irq/41-rockchip-98 [000] .... 290.972410: thermal_power_cpu_get_power:
+ cpus=0000000f freq=1800000 load={{0x0,0x0,0x0,0x0}} dynamic_power=4815
+
+vs
+
+ irq/41-rockchip-96 [000] .... 95.773585: thermal_power_cpu_get_power:
+ cpus=0000000f freq=1800000 load={{0x56,0x64,0x64,0x5e}} dynamic_power=4959
+ irq/41-rockchip-96 [000] .... 95.773596: thermal_power_cpu_limit:
+ cpus=0000000f freq=408000 cdev_state=10 power=416
+
+There seems to be no good reason for omitting the CPU load information
+depending on another tracepoint. My guess is that the intention was to
+check whether thermal_power_cpu_get_power is (still) enabled, however
+'load_cpu != NULL' already indicates that it was at least enabled when
+cpufreq_get_requested_power() was entered, there seems little gain
+from omitting the assignment if the tracepoint was just disabled, so
+just remove the check.

+
+[ Upstream commit 737889efe9713a0f20a75fd0de952841d9275e6b ]
+
+When checking the code with clang -Wsometimes-uninitialized we get the

+
+We fix this by initializing 'maddr' to NULL. For the matter of clarity,
+we also test if 'xmitq' is non-empty before we use it and 'maddr'
+further down in the function. It will never happen that 'xmitq' is non-
+empty at the same time as 'maddr' is NULL, so this is a sufficient test.

+Subject: usb: phy: twl6030-usb: fix possible use-after-free on remove
+
+From: Sven Van Asbroeck <thesven73@gmail.com>
+
+[ Upstream commit 5895d311d28f2605e2f71c1a3e043ed38f3ac9d2 ]
+
+In remove(), use cancel_delayed_work_sync() to cancel the
+delayed work. Otherwise there's a chance that this work
+will continue to run until after the device has been removed.
+
+This issue was detected with the help of Coccinelle.

+Subject: vfio_pci: Enable memory accesses before calling pci_map_rom
+
+From: Eric Auger <eric.auger@redhat.com>
+
+[ Upstream commit 0cfd027be1d6def4a462cdc180c055143af24069 ]
+
+pci_map_rom/pci_get_rom_size() performs memory access in the ROM.
+In case the Memory Space accesses were disabled, readw() is likely
+to trigger a synchronous external abort on some platforms.
+
+In case memory accesses were disabled, re-enable them before the
+call and disable them back again just after.

+Subject: x86/kgbd: Use NMI_VECTOR not APIC_DM_NMI
+
+From: Thomas Gleixner <tglx@linutronix.de>
+
+[ Upstream commit 2591bc4e8d70b4e1330d327fb7e3921f4e070a51 ]
+
+apic->send_IPI_allbutself() takes a vector number as argument.
+
+APIC_DM_NMI is clearly not a vector number. It's defined to 0x400 which is
+outside the vector space.
+
+Use NMI_VECTOR instead as that's what it is intended to be.

+From: Dan Carpenter <dan.carpenter@oracle.com>
+
+[ Upstream commit 201676095dda7e5b31a5e1d116d10fc22985075e ]
+
+The "cpu" variable comes from the sscanf() so Smatch marks it as
+untrusted data. We can't pass a higher value than "nr_cpu_ids" to
+cpu_possible() or it results in an out of bounds access.
