+Subject: ASoC: Intel: Add DMI quirk table to soc_intel_is_byt_cr()
+
+From: Hans de Goede <hdegoede@redhat.com>
+
+[ Upstream commit 8ade6d8b02b1ead741bd4f6c42921035caab6560 ]
+
+Some Bay Trail systems:
+1. Use a non CR version of the Bay Trail SoC
+2. Contain at least 6 interrupt resources so that the
+   platform_get_resource(pdev, IORESOURCE_IRQ, 5) check to workaround
+   non CR systems which list their IPC IRQ at index 0 despite being
+   non CR does not work
+3. Despite 1. and 2. still have their IPC IRQ at index 0 rather then 5
+
+Add a DMI quirk table to check for the few known models with this issue,
+so that the right IPC IRQ index is used on these systems.

+Subject: ASoC: Intel: bytcr_rt5640: Add quirk for the Acer One S1002 tablet
+
+From: Hans de Goede <hdegoede@redhat.com>
+
+[ Upstream commit c58947af08aedbdee0fce5ea6e6bf3e488ae0e2c ]
+
+The Acer One S1002 tablet is using an analog mic on IN1 and has
+its jack-detect connected to JD2_IN4N, instead of using the default
+IN3 for its internal mic and JD1_IN4P for jack-detect.
+
+Note it is also using AIF2 instead of AIF1 which is somewhat unusual,
+this is correctly advertised in the ACPI CHAN package, so the speakers
+do work without the quirk.
+
+Add a quirk for the mic and jack-detect settings.

+[ Upstream commit bdea43fc0436c9e98fdfe151c2ed8a3fc7277404 ]
+
+The Estar Beauty HD MID 7316R tablet almost fully works with out default
+settings. The only problem is that it has only 1 speaker so any sounds
+only playing on the right channel get lost.
+
+Add a quirk for this model using the default settings + MONO_SPEAKER.

+
+[ Upstream commit df8359c512fa770ffa6b0b0309807d9b9825a47f ]
+
+Add a DMI quirk for the Jumper EZpad 7 tablet, this tablet has
+a jack-detect switch which reads 1/high when a jack is inserted,
+rather then using the standard active-low setup which most

+
+Add a DMI-quirk setting the defaults + the BYT_RT5651_JD_NOT_INV
+flags for this.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit

+From: Miaoqing Pan <miaoqing@codeaurora.org>
+
+[ Upstream commit b55379e343a3472c35f4a1245906db5158cab453 ]
+
+Failed to transmit wmi management frames:
+
+[84977.840894] ath10k_snoc a000000.wifi: wmi mgmt tx queue is full
+[84977.840913] ath10k_snoc a000000.wifi: failed to transmit packet, dropping: -28
+[84977.840924] ath10k_snoc a000000.wifi: failed to submit frame: -28
+[84977.840932] ath10k_snoc a000000.wifi: failed to transmit frame: -28
+
+This issue is caused by race condition between skb_dequeue and
+__skb_queue_tail. The queue of â€˜wmi_mgmt_tx_queue’ is protected by a
+different lock: ar->data_lock vs list->lock, the result is no protection.
+So when ath10k_mgmt_over_wmi_tx_work() and ath10k_mac_tx_wmi_mgmt()
+running concurrently on different CPUs, there appear to be a rare corner
+cases when the queue length is 1,
+
+  CPUx (skb_deuque)                    CPUy (__skb_queue_tail)
+                                       next=list
+                                       prev=list
+  struct sk_buff *skb = skb_peek(list);        WRITE_ONCE(newsk->next, next);
+  WRITE_ONCE(list->qlen, list->qlen - 1);WRITE_ONCE(newsk->prev, prev);
+  next       = skb->next;              WRITE_ONCE(next->prev, newsk);
+  prev       = skb->prev;              WRITE_ONCE(prev->next, newsk);
+  skb->next  = skb->prev = NULL;       list->qlen++;
+  WRITE_ONCE(next->prev, prev);
+  WRITE_ONCE(prev->next, next);
+
+If the instruction â€˜next = skb->next’ is executed before
+‘WRITE_ONCE(prev->next, newsk)’, newsk will be lost, as CPUx get the
+old â€˜next’ pointer, but the length is still added by one. The final
+result is the length of the queue will reach the maximum value but
+the queue is empty.
+
+So remove ar->data_lock, and use 'skb_queue_tail' instead of
+'__skb_queue_tail' to prevent the potential race condition. Also switch
+to use skb_queue_len_lockless, in case we queue a few SKBs simultaneously.

+
+[ Upstream commit a338c874d3d9d2463f031e89ae14942929b93db6 ]
+
+The Voyo winpad A15 tablet contains quite generic names in the sys_vendor
+and product_name DMI strings, without this patch brcmfmac will try to load:

+as nvram file which is a bit too generic.
+
+Add a DMI quirk so that a unique and clearly identifiable nvram file name
+is used on the Voyo winpad A15 tablet.
+
+While preparing a matching linux-firmware update I noticed that the nvram
+is identical to the nvram used on the Prowise-PT301 tablet, so the new DMI
+quirk entry simply points to the already existing Prowise-PT301 nvram file.

+Subject: btrfs: fix error handling in commit_fs_roots
+
+From: Josef Bacik <josef@toxicpanda.com>
+
+[ Upstream commit 4f4317c13a40194940acf4a71670179c4faca2b5 ]
+
+While doing error injection I would sometimes get a corrupt file system.
+This is because I was injecting errors at btrfs_search_slot, but would
+only do it one time per stack.  This uncovered a problem in
+commit_fs_roots, where if we get an error we would just break.  However
+we're in a nested loop, the first loop being a loop to find all the
+dirty fs roots, and then subsequent root updates would succeed clearing
+the error value.
+
+This isn't likely to happen in real scenarios, however we could
+potentially get a random ENOMEM once and then not again, and we'd end up
+with a corrupted file system.  Fix this by moving the error checking
+around a bit to the main loop, as this is the only place where something
+will fail, and return the error as soon as it occurs.
+
+With this patch my reproducer no longer corrupts the file system.

+
+[ Upstream commit 303fd3e1c771077e32e96e5788817f025f0067e2 ]
+
+The signed long type used for printing the number of bytes processed in
+tcrypt benchmarks limits the range to -/+ 2 GiB, which is not sufficient
+to cover the performance of common accelerated ciphers such as AES-NI
+when benchmarked with sec=1. So switch to u64 instead.
+
+While at it, fix up a missing printk->pr_cont conversion in the AEAD
+benchmark.

+

+
+[Why]
+If the BIOS table is invalid or corrupt then get_i2c_info can fail
+and we dereference a NULL pointer.
+
+[How]
+Check that ddc_pin is not NULL before using it and log an error if it
+is because this is unexpected.

+MIME-Version: 1.0

+[ Upstream commit e4180c4253f3f2da09047f5139959227f5cf1173 ]
+
+Similar to commit <b82175750131>("drm/amdgpu: fix IH overflow on Vega10 v2").
+When an ring buffer overflow happens the appropriate bit is set in the WPTR
+register which is also written back to memory. But clearing the bit in the
+WPTR doesn't trigger another memory writeback.
+
+So what can happen is that we end up processing the buffer overflow over and
+over again because the bit is never cleared. Resulting in a random system
+lockup because of an infinite loop in an interrupt handler.

+
+[ Upstream commit 958dc1d32c80566f58d18f05ef1f05bd32d172c1 ]
+
+A crash happens when inject failed reconnection.
+If reconnect failed after start io queues, the queues will be unquiesced
+and new requests continue to be delivered. Reconnection error handling
+process directly free queues without cancel suspend requests. The
+suppend request will time out, and then crash due to use the queue
+after free.
+
+Add sync queues and cancel suppend requests for reconnection error
+handling.

+64-bit IRQ stack size to 64 KB.  The 64-bit stack size needs to be larger than the 32-bit stack

+
+From: Jim Mattson <jmattson@google.com>
+
+[ Upstream commit b3c3361fe325074d4144c29d46daae4fc5a268d5 ]
+
+Cascade Lake Xeon parts have the same model number as Skylake Xeon
+parts, so they are tagged with the intel_pebs_isolation
+quirk. However, as with Skylake Xeon H0 stepping parts, the PEBS
+isolation issue is fixed in all microcode versions.
+
+Add the Cascade Lake Xeon steppings (5, 6, and 7) to the
+isolation_ucodes[] table so that these parts benefit from Andi's
+optimization in commit 9b545c04abd4f ("perf/x86/kvm: Avoid unnecessary

+
+[ Upstream commit 275b1e88cabb34dbcbe99756b67e9939d34a99b6 ]
+
+pktgen create threads for all online cpus and bond these threads to
+relevant cpu repecivtily. when this thread firstly be woken up, it
+will compare cpu currently running with the cpu specified at the time
+of creation and if the two cpus are not equal, BUG_ON() will take effect
+causing panic on the system.
+Notice that these threads could be migrated to other cpus before start
+running because of the cpu hotplug after these threads have created. so the
+BUG_ON() used here seems unreasonable and we can replace it with WARN_ON()
+to just printf a warning other than panic the system.

+Subject: sched/features: Fix hrtick reprogramming
+
+From: Juri Lelli <juri.lelli@redhat.com>
+
+[ Upstream commit 156ec6f42b8d300dbbf382738ff35c8bad8f4c3a ]
+
+Hung tasks and RCU stall cases were reported on systems which were not
+100% busy. Investigation of such unexpected cases (no sign of potential
+starvation caused by tasks hogging the system) pointed out that the
+periodic sched tick timer wasn't serviced anymore after a certain point
+and that caused all machinery that depends on it (timers, RCU, etc.) to
+stop working as well. This issues was however only reproducible if
+HRTICK was enabled.
+
+Looking at core dumps it was found that the rbtree of the hrtimer base
+used also for the hrtick was corrupted (i.e. next as seen from the base
+root and actual leftmost obtained by traversing the tree are different).
+Same base is also used for periodic tick hrtimer, which might get "lost"
+if the rbtree gets corrupted.
+
+Much alike what described in commit 1f71addd34f4c ("tick/sched: Do not
+mess with an enqueued hrtimer") there is a race window between
+hrtimer_set_expires() in hrtick_start and hrtimer_start_expires() in
+__hrtick_restart() in which the former might be operating on an already
+queued hrtick hrtimer, which might lead to corruption of the base.
+
+Use hrtick_start() (which removes the timer before enqueuing it back) to
+ensure hrtick hrtimer reprogramming is entirely guarded by the base
+lock, so that no race conditions can occur.

+[ Upstream commit f31559af97a0eabd467e4719253675b7dccb8a46 ]
+
+When fw_core_add_address_handler() fails, we need to destroy

+The constant 20 makes the font sum computation signed which can lead to

+Subject: wlcore: Fix command execute failure 19 for wl12xx
+
+From: Tony Lindgren <tony@atomide.com>
+
+[ Upstream commit cb88d01b67383a095e3f7caeb4cdade5a6cf0417 ]
+
+We can currently get a "command execute failure 19" error on beacon loss
+if the signal is weak:
+
+wlcore: Beacon loss detected. roles:0xff
+wlcore: Connection loss work (role_id: 0).
+...
+wlcore: ERROR command execute failure 19
+...
+WARNING: CPU: 0 PID: 1552 at drivers/net/wireless/ti/wlcore/main.c:803
+...
+(wl12xx_queue_recovery_work.part.0 [wlcore])
+(wl12xx_cmd_role_start_sta [wlcore])
+(wl1271_op_bss_info_changed [wlcore])
+(ieee80211_prep_connection [mac80211])
+
+Error 19 is defined as CMD_STATUS_WRONG_NESTING from the wlcore firmware,
+and seems to mean that the firmware no longer wants to see the quirk
+handling for WLCORE_QUIRK_START_STA_FAILS done.
+
+This quirk got added with commit 18eab430700d ("wlcore: workaround
+start_sta problem in wl12xx fw"), and it seems that this already got fixed
+in the firmware long time ago back in 2012 as wl18xx never had this quirk
+in place to start with.
+
+As we no longer even support firmware that early, to me it seems that it's
+safe to just drop WLCORE_QUIRK_START_STA_FAILS to fix the error. Looks
+like earlier firmware got disabled back in 2013 with commit 0e284c074ef9
+("wl12xx: increase minimum singlerole firmware version required").
+
+If it turns out we still need WLCORE_QUIRK_START_STA_FAILS with any
+firmware that the driver works with, we can simply revert this patch and
+add extra checks for firmware version used.
+
+With this fix wlcore reconnects properly after a beacon loss.

+Subject: x86/build: Treat R_386_PLT32 relocation as R_386_PC32
+
+From: Fangrui Song <maskray@google.com>
+
+[ Upstream commit bb73d07148c405c293e576b40af37737faf23a6a ]
+
+This is similar to commit
+
+  b21ebf2fb4cd ("x86: Treat R_X86_64_PLT32 as R_X86_64_PC32")
+
+but for i386. As far as the kernel is concerned, R_386_PLT32 can be
+treated the same as R_386_PC32.
+
+R_386_PLT32/R_X86_64_PLT32 are PC-relative relocation types which
+can only be used by branches. If the referenced symbol is defined
+externally, a PLT will be used.
+
+R_386_PC32/R_X86_64_PC32 are PC-relative relocation types which can be
+used by address taking operations and branches. If the referenced symbol
+is defined externally, a copy relocation/canonical PLT entry will be
+created in the executable.
+
+On x86-64, there is no PIC vs non-PIC PLT distinction and an
+R_X86_64_PLT32 relocation is produced for both `call/jmp foo` and
+`call/jmp foo@PLT` with newer (2018) GNU as/LLVM integrated assembler.
+This avoids canonical PLT entries (st_shndx=0, st_value!=0).
+
+On i386, there are 2 types of PLTs, PIC and non-PIC. Currently,
+the GCC/GNU as convention is to use R_386_PC32 for non-PIC PLT and
+R_386_PLT32 for PIC PLT. Copy relocations/canonical PLT entries
+are possible ABI issues but GCC/GNU as will likely keep the status
+quo because (1) the ABI is legacy (2) the change will drop a GNU
+ld diagnostic for non-default visibility ifunc in shared objects.
+
+clang-12 -fno-pic (since [1]) can emit R_386_PLT32 for compiler
+generated function declarations, because preventing canonical PLT
+entries is weighed over the rare ifunc diagnostic.

+On this system the M.2 PCIe WiFi card isn't detected after reboot, only
