We have accessing P2SB from a very few places for quite known hardware.

When a new SoC appears in intel-family.h it's not obvious that it needs
to be added to p2sb.c as well. Instead, provide default BDF and refactor
p2sb_get_devfn() to always succeed. If in the future we would need to
exclude something, we may add a list of unsupported IDs.

After upgrading BIOS to U82 01.02.01 Rev.A, the console is flooded
strange char "^@" which printed out every second and makes login
nearly impossible. Also the below messages were shown both in console
and journal/dmesg every second:

usb 1-3: Device not responding to setup address.
usb 1-3: device not accepting address 4, error -71
usb 1-3: device descriptor read/all, error -71
usb usb1-port3: unable to enumerate USB device

Wifi is soft blocked by checking rfkill. When unblocked manually,
after few seconds it would be soft blocked again. So I was suspecting
something triggered rfkill to soft block wifi.  At the end it was
fixed by removing hp_wmi module.

The root cause is the way hp-wmi driver handles command 1B on
post-2009 BIOS.  In pre-2009 BIOS, command 1Bh return 0x4 to indicate
that BIOS no longer controls the power for the wireless devices.

Changes in v2:
- Add a comment that this needs to be revisited when dynamic-mux
  support gets added (suggested by: Daniel Dadap)

Testing has shown that there are quite a few laptop models which rely
on native backlight control and which do not support ACPI video bus
backlight control, causing __acpi_video_get_backlight_type() to return
vendor. Known Windows laptop models affected by this are:

Acer Aspire 1640
HP Compaq nc6120
IBM ThinkPad X40
System76 Starling Star1

and the following MacBook models are affected too:

Apple MacBook 2.1
Apple MacBook 4.1
Apple MacBook Pro 7.1

the list of affected Windows laptop models is likely just the top of
the iceberg. So for now lets undo the change to not register native
backlight class devices when __acpi_video_get_backlight_type() != native.

Since as part of the backlight-detect refactor the detection code now
relies on the GPU drivers calling acpi_video_backlight_use_native() to
learn that native backlight support is available we cannot just remove
the acpi_video_backlight_use_native() calls from the GPU drivers.

Instead modify acpi_video_backlight_use_native() to always return true
for now. This is meant as a temporary work-around, which will be removed
again when the heuristics from __acpi_video_get_backlight_type() have
been improved so that they will return native on affected models.

2 improvements for the Chromebook handling in

1. Also check for the "GOOG000C" ACPI HID used on some models
2. Move the Chromebook check to above the ACPI-video check normally
   Chromebooks don't have ACPI video backlight support, but when
   flashed with upstream coreboot builds they may have ACPI video
   backlight support, but native should still be used/preferred then.

Pull cxl fixes from Dan Williams:
 "Several fixes for CXL region creation crashes, leaks and failures.

  This is mainly fallout from the original implementation of dynamic CXL
  region creation (instantiate new physical memory pools) that arrived
  in v6.0-rc1.

  Given the theme of "failures in the presence of pass-through decoders"
  this also includes new regression test infrastructure for that case.

  Summary:

   - Fix region creation crash with pass-through decoders

   - Fix region creation crash when no decoder allocation fails

   - Fix region creation crash when scanning regions to enforce the
     increasing physical address order constraint that CXL mandates

   - Fix a memory leak for cxl_pmem_region objects, track 1:N instead of
     1:1 memory-device-to-region associations.

   - Fix a memory leak for cxl_region objects when regions with active
     targets are deleted

   - Fix assignment of NUMA nodes to CXL regions by CFMWS (CXL Window)
     emulated proximity domains.

   - Fix region creation failure for switch attached devices downstream
     of a single-port host-bridge

   - Fix false positive memory leak of cxl_region objects by recycling
     recently used region ids rather than freeing them

   - Add regression test infrastructure for a pass-through decoder

   - Fix some mailbox payload handling corner cases"

To solve above issue, forbid inode do migrate which has inline data.

The rec_len field in the directory entry has to be a multiple of 4.  A
corrupted filesystem image can be used to hit a BUG() in
ext4_rec_len_to_disk(), called from make_indexed_dir().

The fix simply adds a call to ext4_check_dir_entry() to validate the
directory entry, returning -EFSCORRUPTED if the entry is invalid.

With mt7621 soc_dev_attr fixed to register the soc as a device,
kernel will experience an oops in soc_device_match_attr

This quirk test was introduced in the staging driver in
commit 9445ccb3 ("staging: mt7621-pci-phy: add quirks for 'E2'
revision using 'soc_device_attribute'"). The staging driver was removed,
and later re-added in commit d87da323 ("phy: ralink: Add PHY driver
for MT7621 PCIe PHY") for kernel 5.11
