e10d451e10 arm64: dts: qcom: sm6350: Add resets for SDHCI 1/2
Make sure the SDHCI hardware is properly reset before interacting with
it, to protect against any possibly indeterminate state left by the
bootloader.

62fa3ce05d scsi: ibmvfc: Avoid path failures during live migration
Fix an issue reported when performing a live migration when multipath is
configured with a short fast fail timeout of 5 seconds and also to have
no_path_retry set to fail. In this scenario, all paths would go into the
devloss state while the ibmvfc driver went through discovery to log back
in. On a loaded system, the discovery might take longer than 5 seconds,
which was resulting in all paths being marked failed, which then resulted
in a read only filesystem.

This patch changes the migration code in ibmvfc to avoid deleting rports at
all in this scenario, so we avoid losing all paths.

e13757f524 Input: soc_button_array - add Acer Switch V 10 to dmi_use_low_level_irq[]
Like on the Acer Switch 10 SW5-012, the Acer Switch V 10 SW5-017's _LID
method messes with home- and power-button GPIO IRQ settings, causing an
IRQ storm.

Add a quirk entry for the Acer Switch V 10 to the dmi_use_low_level_irq[]
DMI quirk list, to use low-level IRQs on this model, fixing the IRQ storm.

8e9ada1d0e Input: soc_button_array - add use_low_level_irq module parameter
It seems that the Windows drivers for the ACPI0011 soc_button_array
device use low level triggered IRQs rather then using edge triggering.

Some ACPI tables depend on this, directly poking the GPIO controller's
registers to clear the trigger type when closing a laptop's/2-in-1's lid
and re-instating the trigger when opening the lid again.

Linux sets the edge/level on which to trigger to both low+high since
it is using edge type IRQs, the ACPI tables then ends up also setting
the bit for level IRQs and since both low and high level have been
selected by Linux we get an IRQ storm leading to soft lockups.

As a workaround for this the soc_button_array already contains
a DMI quirk table with device models known to have this issue.

Add a module parameter for this so that users can easily test if their
device is affected too and so that they can use the module parameter
as a workaround.

commit 6ac0aec6b0 ("Input: iforce - allow callers supply data buffer

returning 0, the caller needs to check that valid length is longer than or
equals to bytes to read.

Merge tag 'platform-drivers-x86-v6.1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86

Pull x86 platform driver fixes from Hans de Goede:
 "The most important fixes here are a set of fixes for the ACPI
  backlight detection refactor which landed in 6.1.

  These fix regressions reported on some laptop models by making
  acpi_video_backlight_use_native() always return true for now, which in
  essence undoes some of the changes.

  I plan to take another shot at having only 1 /sys/class/backlight
  class device per panel with 6.2, with modified detection heuristics to
  avoid the (known) regressions.

  Highlights:

   - ACPI: video: Fix regressions from 6.1 backlight refactor by making
     acpi_video_backlight_use_native() always return true for now

   - Misc other bugfixes and HW id additions"

f6b1a1cf1c ext4: fix use-after-free in ext4_ext_shift_extents
If the starting position of our insert range happens to be in the hole
between the two ext4_extent_idx, because the lblk of the ext4_extent in
the previous ext4_extent_idx is always less than the start, which leads
to the "extent" variable access across the boundary, the following UAF is
triggered:
==================================================================
BUG: KASAN: use-after-free in ext4_ext_shift_extents+0x257/0x790

==================================================================

For right shifts, we can divide them into the following situations:

1. When the first ee_block of ext4_extent_idx is greater than or equal to
   start, make right shifts directly from the first ee_block.
    1) If it is greater than start, we need to continue searching in the
       previous ext4_extent_idx.
    2) If it is equal to start, we can exit the loop (iterator=NULL).

2. When the first ee_block of ext4_extent_idx is less than start, then
   traverse from the last extent to find the first extent whose ee_block
   is less than start.
    1) If extent is still the last extent after traversal, it means that
       the last ee_block of ext4_extent_idx is less than start, that is,
       start is located in the hole between idx and (idx+1), so we can
       exit the loop directly (break) without right shifts.
    2) Otherwise, make right shifts at the corresponding position of the
       found extent, and then exit the loop (iterator=NULL).
