[PATCH 5.10 01/49] ACPICA: Fix race in generic_serial_bus (I2C) and GPIO op_region parameter handling

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Hans de Goede <hdegoede@redhat.com>

commit c27f3d011b08540e68233cf56274fdc34bebb9b5 upstream.

ACPICA commit c9e0116952363b0fa815143dca7e9a2eb4fefa61

The handling of the generic_serial_bus (I2C) and GPIO op_regions in
acpi_ev_address_space_dispatch() passes a number of extra parameters
to the address-space handler through the address-space Context pointer
(instead of using more function parameters).

The Context is shared between threads, so if multiple threads try to
call the handler for the same address-space at the same time, then
a second thread could change the parameters of a first thread while
the handler is running for the first thread.

An example of this race hitting is the Lenovo Yoga Tablet2 1015L,
where there are both attrib_bytes accesses and attrib_byte accesses
to the same address-space. The attrib_bytes access stores the number
of bytes to transfer in Context->access_length. Where as for the
attrib_byte access the number of bytes to transfer is always 1 and
field_obj->Field.access_length is unused (so 0). Both types of
accesses racing from different threads leads to the following problem:

 1. Thread a. starts an attrib_bytes access, stores a non 0 value
    from field_obj->Field.access_length in Context->access_length

 2. Thread b. starts an attrib_byte access, stores 0 in
    Context->access_length

 3. Thread a. calls i2c_acpi_space_handler() (under Linux). Which
    sees that the access-type is ACPI_GSB_ACCESS_ATTRIB_MULTIBYTE
    and calls acpi_gsb_i2c_read_bytes(..., Context->access_length)

 4. At this point Context->access_length is 0 (set by thread b.)

rather then the field_obj->Field.access_length value from thread a.
This 0 length reads leads to the following errors being logged:

 i2c i2c-0: adapter quirk: no zero length (addr 0x0078, size 0, read)
 i2c i2c-0: i2c read 0 bytes from client@0x78 starting at reg 0x0 failed, error: -95

Note this is just an example of the problems which this race can cause.

There are likely many more (sporadic) problems caused by this race.

This commit adds a new context_mutex to struct acpi_object_addr_handler
and makes acpi_ev_address_space_dispatch() take that mutex when
using the shared Context to pass extra parameters to an address-space
handler, fixing this race.

Note the new mutex must be taken *after* exiting the interpreter,
therefor the existing acpi_ex_exit_interpreter() call is moved to above
the code which stores the extra parameters in the Context.

[PATCH 5.10 02/49] [PATCH v2] ASoC: SOF: Intel: broadwell: fix mutual exclusion with catpt driver

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

In v5.10, the "haswell" driver was replaced by the "catpt" driver, but
the mutual exclusion with the SOF driver was not updated. This leads
to errors with card names and UCM profiles not being loaded by
PulseAudio.

This fix should only be applied on v5.10-stable, the mutual exclusion
was removed in 5.11.

[PATCH 5.10 03/49] nvme-pci: mark Kingston SKC2000 as not supporting the deepest power state

commit dc22c1c058b5c4fe967a20589e36f029ee42a706 upstream

My 2TB SKC2000 showed the exact same symptoms that were provided
in 538e4a8c57 ("nvme-pci: avoid the deepest sleep state on
Kingston A2000 SSDs"), i.e. a complete NVME lockup that needed
cold boot to get it back.

According to some sources, the A2000 is simply a rebadged
SKC2000 with a slightly optimized firmware.

Adding the SKC2000 PCI ID to the quirk list with the same workaround
as the A2000 made my laptop survive a 5 hours long Yocto bootstrap
buildfest which reliably triggered the SSD lockup previously.

[PATCH 5.10 04/49] parisc: Enable -mlong-calls gcc option with CONFIG_COMPILE_TEST

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Helge Deller <deller@gmx.de>

commit 778e45d7720d663811352943dd515b41f6849637 upstream

The kernel test robot reported multiple linkage problems like this:

    hppa64-linux-ld: init/main.o(.init.text+0x56c): cannot reach printk
    init/main.o: in function `unknown_bootoption':
    (.init.text+0x56c): relocation truncated to fit: R_PARISC_PCREL22F against
	symbol `printk' defined in .text.unlikely section in kernel/printk/printk.o

There are two ways to solve it:
a) Enable the -mlong-call compiler option (CONFIG_MLONGCALLS),
b) Add long branch stub support in 64-bit linker.

While b) is the long-term solution, this patch works around the issue by
automatically enabling the CONFIG_MLONGCALLS option when
CONFIG_COMPILE_TEST is set, which indicates that a non-production kernel
(e.g. 0-day kernel) is built.

[PATCH 5.10 05/49] arm64: Make CPU_BIG_ENDIAN depend on ld.bfd or ld.lld 13.0.0+

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Nathan Chancellor <nathan@kernel.org>

commit e9c6deee00e9197e75cd6aa0d265d3d45bd7cc28 upstream

Similar to commit 28187dc8ebd9 ("ARM: 9025/1: Kconfig: CPU_BIG_ENDIAN
depends on !LD_IS_LLD"), ld.lld prior to 13.0.0 does not properly
support aarch64 big endian, leading to the following build error when
CONFIG_CPU_BIG_ENDIAN is selected:

ld.lld: error: unknown emulation: aarch64linuxb

This has been resolved in LLVM 13. To avoid errors like this, only allow
CONFIG_CPU_BIG_ENDIAN to be selected if using ld.bfd or ld.lld 13.0.0
and newer.

While we are here, the indentation of this symbol used spaces since its
introduction in commit a872013d6d03 ("arm64: kconfig: allow
CPU_BIG_ENDIAN to be selected"). Change it to tabs to be consistent with
kernel coding style.

[PATCH 5.10 07/49] btrfs: dont flush from btrfs_delayed_inode_reserve_metadata

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Nikolay Borisov <nborisov@suse.com>

commit 4d14c5cde5c268a2bc26addecf09489cb953ef64 upstream

Calling btrfs_qgroup_reserve_meta_prealloc from
btrfs_delayed_inode_reserve_metadata can result in flushing delalloc
while holding a transaction and delayed node locks. This is deadlock
prone. In the past multiple commits:

 * ae5e070eaca9 ("btrfs: qgroup: don't try to wait flushing if we're
already holding a transaction")

 * 6f23277a49e6 ("btrfs: qgroup: don't commit transaction when we already
 hold the handle")

Tried to solve various aspects of this but this was always a
whack-a-mole game. Unfortunately those 2 fixes don't solve a deadlock
scenario involving btrfs_delayed_node::mutex. Namely, one thread
can call btrfs_dirty_inode as a result of reading a file and modifying
its atime:

  PID: 6963   TASK: ffff8c7f3f94c000  CPU: 2   COMMAND: "test"
  #0  __schedule at ffffffffa529e07d
  #1  schedule at ffffffffa529e4ff

  #3  wait_for_completion at ffffffffa529eeea             <-- sleeps with delayed node mutex held

  #6  try_flush_qgroup at ffffffffc03f04b2
  #7  __btrfs_qgroup_reserve_meta at ffffffffc03f5bb6     <-- tries to reserve space and starts delalloc inodes.
  #8  btrfs_delayed_update_inode at ffffffffc03e31aa      <-- acquires delayed node mutex
  #9  btrfs_update_inode at ffffffffc0385ba8
 #10  btrfs_dirty_inode at ffffffffc038627b               <-- TRANSACTIION OPENED

 #16  do_syscall_64 at ffffffffa4a052eb
 #17  entry_SYSCALL_64_after_hwframe at ffffffffa540008c

This will cause an asynchronous work to flush the delalloc inodes to
happen which can try to acquire the same delayed_node mutex:

  PID: 455    TASK: ffff8c8085fa4000  CPU: 5   COMMAND: "kworker/u16:30"
  #0  __schedule at ffffffffa529e07d
  #1  schedule at ffffffffa529e4ff
  #2  schedule_preempt_disabled at ffffffffa529e80a
  #3  __mutex_lock at ffffffffa529fdcb                    <-- goes to sleep, never wakes up.
  #4  btrfs_delayed_update_inode at ffffffffc03e3143      <-- tries to acquire the mutex
  #5  btrfs_update_inode at ffffffffc0385ba8              <-- this is the same inode that pid 6963 is holding
  #6  cow_file_range_inline.constprop.78 at ffffffffc0386be7
  #7  cow_file_range at ffffffffc03879c1
  #8  btrfs_run_delalloc_range at ffffffffc038894c

 #12  extent_writepages at ffffffffc03a6de2
 #13  do_writepages at ffffffffa4c277eb
 #14  __filemap_fdatawrite_range at ffffffffa4c1e5bb
 #15  btrfs_run_delalloc_work at ffffffffc0380987         <-- starts running delayed nodes
 #16  normal_work_helper at ffffffffc03b706c
 #17  process_one_work at ffffffffa4aba4e4
 #18  worker_thread at ffffffffa4aba6fd
 #19  kthread at ffffffffa4ac0a3d
 #20  ret_from_fork at ffffffffa54001ff

To fully address those cases the complete fix is to never issue any
flushing while holding the transaction or the delayed node lock. This
patch achieves it by calling qgroup_reserve_meta directly which will
either succeed without flushing or will fail and return -EDQUOT. In the
latter case that return value is going to be propagated to
btrfs_dirty_inode which will fallback to start a new transaction. That's
fine as the majority of time we expect the inode will have
BTRFS_DELAYED_NODE_INODE_DIRTY flag set which will result in directly
copying the in-memory state.

[PATCH 5.10 08/49] iommu/amd: Fix sleeping in atomic in increase_address_space()

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Andrey Ryabinin <arbn@yandex-team.com>

commit 140456f994195b568ecd7fc2287a34eadffef3ca upstream.

increase_address_space() calls get_zeroed_page(gfp) under spin_lock with
disabled interrupts. gfp flags passed to increase_address_space() may allow
sleeping, so it comes to this:

[PATCH 5.10 11/49] mwifiex: pcie: skip cancel_work_sync() on reset failure path

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Tsuchiya Yuto <kitakar@gmail.com>

[ Upstream commit 4add4d988f95f47493500a7a19c623827061589b ]

If a reset is performed, but even the reset fails for some reasons (e.g.,
on Surface devices, the fw reset requires another quirks),
cancel_work_sync() hangs in mwifiex_cleanup_pcie().

This is a deadlock caused by calling cancel_work_sync() in
mwifiex_cleanup_pcie():

- Device resets are done via mwifiex_pcie_card_reset()
- which schedules card->work to call mwifiex_pcie_card_reset_work()
- which calls pci_try_reset_function().
- This leads to mwifiex_pcie_reset_done() be called on the same workqueue,
  which in turn calls
- mwifiex_reinit_sw() and that calls
- _mwifiex_fw_dpc().

The problem is now that _mwifiex_fw_dpc() calls mwifiex_free_adapter()
in case firmware initialization fails. That ends up calling
mwifiex_cleanup_pcie().

Note that all those calls are still running on the workqueue. So when
mwifiex_cleanup_pcie() now calls cancel_work_sync(), it's really waiting
on itself to complete, causing a deadlock.

This commit fixes the deadlock by skipping cancel_work_sync() on a reset
failure path.

After this commit, when reset fails, the following output is
expected to be shown:

    kernel: mwifiex_pcie 0000:03:00.0: info: _mwifiex_fw_dpc: unregister device
    kernel: mwifiex: Failed to bring up adapter: -5
    kernel: mwifiex_pcie 0000:03:00.0: reinit failed: -5

To reproduce this issue, for example, try putting the root port of wifi
into D3 (replace "00:1d.3" with your setup).

    # put into D3 (root port)
    sudo setpci -v -s 00:1d.3 CAP_PM+4.b=0b

[PATCH 5.10 14/49] net: ipa: ignore CHANNEL_NOT_RUNNING errors

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Alex Elder <elder@linaro.org>

[ Upstream commit f849afcc8c3b27d7b50827e95b60557f24184df0 ]

IPA v4.2 has a hardware quirk that requires the AP to allocate GSI
channels for the modem to use.  It is recommended that these modem
channels get stopped (with a HALT generic command) by the AP when
its IPA driver gets removed.

The AP has no way of knowing the current state of a modem channel.
So when the IPA driver issues a HALT command it's possible the
channel is not running, and in that case we get an error indication.
This error simply means we didn't need to stop the channel, so we
can ignore it.

This patch adds an explanation for this situation, and arranges for
this condition to *not* report an error message.

[PATCH 5.10 16/49] platform/x86: acer-wmi: Cleanup accelerometer device handling

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit 9feb0763e4985ccfae632de3bb2f029cc8389842 ]

Cleanup accelerometer device handling:
-Drop acer_wmi_accel_destroy instead directly call input_unregister_device.
-The information tracked by the CAP_ACCEL flag mirrors acer_wmi_accel_dev
 being NULL. Drop the CAP flag, this is a preparation change for allowing
 users to override the capability flags. Dropping the flag stops users
 from causing a NULL pointer dereference by forcing the capability.

[PATCH 5.10 17/49] platform/x86: acer-wmi: Add new force_caps module parameter

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit 39aa009bb66f9d5fbd1e58ca4aa03d6e6f2c9915 ]

Add a new force_caps module parameter to allow overriding the drivers
builtin capability detection mechanism.

This can be used to for example:
-Disable rfkill functionality on devices where there is an AA OEM DMI
 record advertising non functional rfkill switches
-Force loading of the driver on devices with a missing AA OEM DMI record

Note that force_caps is -1 when unset, this allows forcing the
capability field to 0, which results in acer-wmi only providing WMI
hotkey handling while disabling all other (led, rfkill, backlight)
functionality.

[PATCH 5.10 18/49] platform/x86: acer-wmi: Add ACER_CAP_SET_FUNCTION_MODE capability flag

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit 82cb8a5c395ea5be20e0fe31a8fe84380a502ca5 ]

Not all devices supporting WMID_GUID3 support the wmid3_set_function_mode()
call, leading to errors like these:

[   60.138358] acer_wmi: Enabling RF Button failed: 0x1 - 0xff
[   60.140036] acer_wmi: Enabling Launch Manager failed: 0x1 - 0xff

Add an ACER_CAP_SET_FUNCTION_MODE capability flag, so that these calls
can be disabled through the new force_caps mechanism.

[PATCH 5.10 19/49] platform/x86: acer-wmi: Add support for SW_TABLET_MODE on Switch devices

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit 5c54cb6c627e8f50f490e6b5656051a5ac29eab4 ]

Add support for SW_TABLET_MODE on the Acer Switch 10 (SW5-012) and the
acer Switch 10 (S1003) models.

There is no way to detect if this is supported, so this uses DMI based
quirks setting force_caps to ACER_CAP_KBD_DOCK (these devices have no
other acer-wmi based functionality).

The new SW_TABLET_MODE functionality can be tested on devices which
are not in the DMI table by passing acer_wmi.force_caps=0x40 on the
kernel commandline.

[PATCH 5.10 21/49] HID: mf: add support for 0079:1846 Mayflash/Dragonrise USB Gamecube Adapter

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Ethan Warth <redyoshi49q@gmail.com>

[ Upstream commit 1008230f2abeb624f6d71b2e1c424fa4eeebbf84 ]

Mayflash/Dragonrise seems to have yet another device ID for one of their
Gamecube controller adapters.  Previous to this commit, the adapter
registered only one /dev/input/js* device, and all controller inputs (from
any controller) were mapped to this device.  This patch defines the 1846
USB device ID and enables the HID_QUIRK_MULTI_INPUT quirk for it, which
fixes that (with the patch, four /dev/input/js* devices are created, one
for each of the four controller ports).

[PATCH 5.10 22/49] media: cx23885: add more quirks for reset DMA on some AMD IOMMU

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Daniel Lee Kruse <daniel.lee.kruse@protonmail.com>

[ Upstream commit dbf0b3a7b719eb3f72cb53c2ce7d34a012a9c261 ]

On AMD Family 15h (Models 30h-3fh), I/O Memory Management Unit
RiSC engine sometimes stalls, requiring a reset.

As result, MythTV and w-scan won't scan channels on the AMD Kaveri
APU with the Hauppauge QuadHD TV tuner card.

For the solution I added the Input/Output Memory Management Unit's PCI
Identity of 0x1423 to the broken_dev_id[] array, which is used by
a quirks logic meant to fix similar problems with other AMD
chipsets.

[PATCH 5.10 23/49] ACPI: video: Add DMI quirk for GIGABYTE GB-BXBT-2807

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Jasper St. Pierre <jstpierre@mecheye.net>

[ Upstream commit 25417185e9b5ff90746d50769d2a3fcd1629e254 ]

The GIGABYTE GB-BXBT-2807 is a mini-PC which uses off the shelf
components, like an Intel GPU which is meant for mobile systems.
As such, it, by default, has a backlight controller exposed.

Unfortunately, the backlight controller only confuses userspace, which
sees the existence of a backlight device node and has the unrealistic
belief that there is actually a backlight there!

Add a DMI quirk to force the backlight off on this system.

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Chris Chiu <chiu@endlessos.org>

[ Upstream commit 1bea2256aa96a2d7b1b576eb74e29d79edc9bea8 ]

Tha ARCHOS Cesium 140 tablet has problem with the jack-sensing,
thus the heaset functions are not working.

Add quirk for this model to select the correct input map, jack-detect
options and channel map to enable jack sensing and headset microphone.
This device uses IN1 for its internal MIC and JD2 for jack-detect.

[PATCH 5.10 30/49] KVM: x86: Supplement __cr4_reserved_bits() with X86_FEATURE_PCID check

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Vitaly Kuznetsov <vkuznets@redhat.com>

[ Upstream commit 4683d758f48e6ae87d3d3493ffa00aceb955ee16 ]

Commit 7a873e455567 ("KVM: selftests: Verify supported CR4 bits can be set
before KVM_SET_CPUID2") reveals that KVM allows to set X86_CR4_PCIDE even
when PCID support is missing:

==== Test Assertion Failure ====
  x86_64/set_sregs_test.c:41: rc
  pid=6956 tid=6956 - Invalid argument
     1	0x000000000040177d: test_cr4_feature_bit at set_sregs_test.c:41
     2	0x00000000004014fc: main at set_sregs_test.c:119

     4	0x000000000040164d: _start at ??:?
  KVM allowed unsupported CR4 bit (0x20000)

Add X86_FEATURE_PCID feature check to __cr4_reserved_bits() to make
kvm_is_valid_cr4() fail.

[PATCH 5.10 33/49] scsi: ufs: Add a quirk to permit overriding UniPro defaults

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Kiwoong Kim <kwmad.kim@samsung.com>

[ Upstream commit b1d0d2eb89d4e3a25b212a9d836587503537067e ]

The UniPro specification states that attribute IDs of the following
parameters are vendor-specific so some SoCs could have no regions at the
defined addresses:

 - DME_LocalFC0ProtectionTimeOutVal
 - DME_LocalTC0ReplayTimeOutVal
 - DME_LocalAFC0ReqTimeOutVal

In addition, the following parameters should be set considering the
compatibility between host and device.

 - PA_PWRMODEUSERDATA0
 - PA_PWRMODEUSERDATA1
 - PA_PWRMODEUSERDATA2
 - PA_PWRMODEUSERDATA3
 - PA_PWRMODEUSERDATA4
 - PA_PWRMODEUSERDATA5

Introduce a quirk to allow vendor drivers to override the UniPro defaults.

[PATCH 5.10 34/49] misc: eeprom_93xx46: Add quirk to support Microchip 93LC46B eeprom

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Aswath Govindraju <a-govindraju@ti.com>

[ Upstream commit f6f1f8e6e3eea25f539105d48166e91f0ab46dd1 ]

A dummy zero bit is sent preceding the data during a read transfer by the
Microchip 93LC46B eeprom (section 2.7 of[1]). This results in right shift
of data during a read. In order to ignore this bit a quirk can be added to
send an extra zero bit after the read address.

Add a quirk to ignore the zero bit sent before data by adding a zero bit
after the read address.

[PATCH 5.10 35/49] scsi: ufs: Introduce a quirk to allow only page-aligned sg entries

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Kiwoong Kim <kwmad.kim@samsung.com>

[ Upstream commit 2b2bfc8aa519f696087475ed8e8c61850c673272 ]

Some SoCs require a single scatterlist entry for smaller than page size,
i.e. 4KB. When dispatching commands with more than one scatterlist entry
under 4KB in size the following behavior is observed:

A command to read a block range is dispatched with two scatterlist entries
that are named AAA and BBB. After dispatching, the host builds two PRDT
entries and during transmission, device sends just one DATA IN because
device doesn't care about host DMA. The host then transfers the combined
amount of data from start address of the area named AAA. As a consequence,
the area that follows AAA in memory would be corrupted.

    |<------------->|
    +-------+------------         +-------+
    +  AAA  + (corrupted)   ...   +  BBB  +
    +-------+------------         +-------+

To avoid this we need to enforce page size alignment for sg entries.

[PATCH 5.10 38/49] drm/msm/a5xx: Remove overwriting A5XX_PC_DBG_ECO_CNTL register

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: AngeloGioacchino Del Regno <angelogioacchino.delregno@somainline.org>

[ Upstream commit 8f03c30cb814213e36032084a01f49a9e604a3e3 ]

The PC_DBG_ECO_CNTL register on the Adreno A5xx family gets
programmed to some different values on a per-model basis.
At least, this is what we intend to do here;

Unfortunately, though, this register is being overwritten with a
static magic number, right after applying the GPU-specific
configuration (including the GPU-specific quirks) and that is
effectively nullifying the efforts.

Let's remove the redundant and wrong write to the PC_DBG_ECO_CNTL
register in order to retain the wanted configuration for the
target GPU.

From: Jisheng Zhang <Jisheng.Zhang@synaptics.com>

[ Upstream commit 5f7dfda4f2cec580c135fd81d96a05006651c128 ]

The SDHCI_PRESET_FOR_* registers are not set(all read as zeros), so
set the quirk.

[PATCH 5.10 40/49] HID: i2c-hid: Add I2C_HID_QUIRK_NO_IRQ_AFTER_RESET for ITE8568 EC on Voyo Winpad A15

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit fc6a31b00739356809dd566e16f2c4325a63285d ]

The ITE8568 EC on the Voyo Winpad A15 presents itself as an I2C-HID
attached keyboard and mouse (which seems to never send any events).

This needs the I2C_HID_QUIRK_NO_IRQ_AFTER_RESET quirk, otherwise we get
the following errors:

[ 3688.770850] i2c_hid i2c-ITE8568:00: failed to reset device.
[ 3694.915865] i2c_hid i2c-ITE8568:00: failed to reset device.
[ 3701.059717] i2c_hid i2c-ITE8568:00: failed to reset device.
[ 3707.205944] i2c_hid i2c-ITE8568:00: failed to reset device.
[ 3708.227940] i2c_hid i2c-ITE8568:00: can't add hid device: -61
[ 3708.236518] i2c_hid: probe of i2c-ITE8568:00 failed with error -61

Which leads to a significant boot delay.

[PATCH 5.10 41/49] ALSA: usb-audio: Add DJM750 to Pioneer mixer quirk

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Olivia Mackintosh <livvy@base.nu>

[ Upstream commit a07df82c799013236aa90a140785775eda9f9523 ]

This allows for N different devices to use the pioneer mixer quirk for
setting capture/record type and recording level. The impementation has
not changed much with the exception of an additional mask on
private_value to allow storing of a device index:
	DEVICE MASK	0xff000000
	GROUP_MASK	0x00ff0000
	VALUE_MASK	0x0000ffff

This could be improved by changing the arrays of wValues for each
channel to contain named definitions (e.g. SND_DJM_CAP_LINE). It would
improve readability and perhaps would allow using the same array for
multiple channels. The channel number can be specified on the control
next to the wIndex.

Feedback is very much appreciated as I'm not the most proficient C
programmer but am learning as I go.

[PATCH 5.10 42/49] ALSA: usb-audio: add mixer quirks for Pioneer DJM-900NXS2

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Fabian Lesniak <fabian@lesniak-it.de>

[ Upstream commit fee03efc69345344c8851596d74d93199b175bfe ]

This commit adds mixer quirks for the Pioneer DJM-900NXS2 mixer. This
device has 6 capture channels, 5 of them allow setting the signal
source. This adds controls for these, similar to the DJM-250Mk2.
However, playpack channels are not controllable via software like on the
250Mk2, as they can only be set manually on the mixing console.
Read-only controls showing the currently selected playback channels are
omitted.

[PATCH 5.10 43/49] PCI: cadence: Retrain Link to work around Gen2 training defect

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Nadeem Athani <nadeem@cadence.com>

[ Upstream commit 4740b969aaf58adeca6829947a3ad8da423976cf ]

Cadence controller will not initiate autonomous speed change if strapped
as Gen2. The Retrain Link bit is set as quirk to enable this speed change.

[PATCH 5.10 47/49] KVM: SVM: Clear the CR4 register on reset

[gregkh]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Babu Moger <babu.moger@amd.com>

[ Upstream commit 9e46f6c6c959d9bb45445c2e8f04a75324a0dfd0 ]

This problem was reported on a SVM guest while executing kexec.
Kexec fails to load the new kernel when the PCID feature is enabled.

When kexec starts loading the new kernel, it starts the process by
resetting the vCPU's and then bringing each vCPU online one by one.
The vCPU reset is supposed to reset all the register states before the
vCPUs are brought online. However, the CR4 register is not reset during
this process. If this register is already setup during the last boot,
all the flags can remain intact. The X86_CR4_PCIDE bit can only be
enabled in long mode. So, it must be enabled much later in SMP
initialization.  Having the X86_CR4_PCIDE bit set during SMP boot can
cause a boot failures.

Fix the issue by resetting the CR4 register in init_vmcb().

Yup, and it looks like this fixes the problem for GIGABYTE
GB-BXBT-2807 but re-introduces the problem for Sony VPCEH3U1E.

Something is funny with the From header here. But that's not main
thing -- this patch is evil.

Yup, and it looks like this fixes the problem for GIGABYTE
GB-BXBT-2807 but re-introduces the problem for Sony VPCEH3U1E, because
its .callback is now NULL.

That's what upstream has right now, for 5.11, so I'll take this for now
