Add support for the AYANEO AIR and AYANEO AIR Pro models of handheld
devices. These devices use the same EC registers and logic as the One X
Player mini AMD. Previous AYANEO models are not supported as they use a
different EC and do not have the necessary fan speed write enable and
setting registers. The driver is tested on AYANEO AIR while AIR Pro model
EC functionality and DMI data were verified using command line tools by
another user.
Add:
- AYANEO AIR (AMD 5560U)
- AYANEO AIR Pro (AMD 5560U)
- AYANEO AIR Pro (AMD 5825U)
While at it, fix spelling error (appart -> apart).

Introduce structure for per device fan sensor offsets. This allows
reading fan sensors in aqc_raw_event() from devices which use a
different sensor layout in their status HID report. Currently only one
version is implemented as all supported devices use the same structure.

The coretemp driver uses rdmsr_on_cpu calls to read
MSR_IA32_PACKAGE_THERM_STATUS/MSR_IA32_THERM_STATUS registers,
which contain information about current core temperature.
For certain low latency applications, the RDMSR interruption exceeds
the applications requirements.
So do not create core files in sysfs, for CPUs which have
isolation and nohz_full enabled.
Temperature information from the housekeeping cores should be
sufficient to infer die temperature.

The find_last_bit() call produces the index of the highest-numbered

A user complained that the ftsteutates driver was displaying
bogus values since its introduction. This happens because the
sensor measurements need to be scaled in order to produce
meaningful results:
- the fan speed needs to be multiplied by 60 since its in RPS
- the temperature is in degrees celsius and needs an offset of 64
- the voltage is in 1/256 of 3.3V
The offical datasheet says the voltage needs to be divided by 256,
but this is likely an off-by-one-error, since even the BIOS
devides by 255 (otherwise 3.3V could not be measured).
The voltage channels additionally need a board-specific multiplier,
however this can be done by the driver since its board-specific.
The reason the missing scaling of measurements is the way Fujitsu
used this driver when it was still out-of-tree. Back then, all
scaling was done in userspace by libsensors, even the generic one.
Tested on a Fujitsu DS3401-B1.

Merge ACPI resource handling quirks and ACPI backlight handling fixes
for 6.2-rc2:
- Add ACPI IRQ override quirks for Asus ExpertBook B2502, Lenovo
14ALC7, and XMG Core 15 (Hans de Goede, Adrian Freund, Erik
Schumacher).
- Adjust ACPI video detection fallback path to prevent non-operational
ACPI backlight devices from being created on systems where the native
driver does not detect a suitable panel (Mario Limonciello).
- Fix Apple GMUX backlight detection (Hans de Goede).
* acpi-resource:
ACPI: resource: Add Asus ExpertBook B2502 to Asus quirks
ACPI: resource: do IRQ override on Lenovo 14ALC7
ACPI: resource: do IRQ override on XMG Core 15
* acpi-video:
ACPI: video: Fix Apple GMUX backlight detection
ACPI: video: Don't enable fallback path for creating ACPI backlight by default
drm/amd/display: Report to ACPI video if no panels were found
ACPI: video: Allow GPU drivers to report no panels
Due to copy-paste fail, MIPI_BKLT_EN_1 would always use PPS index 1,
never 0. Fix the sloppiest commit in recent memory.

Starting from ICL, the default for MIPI GPIO sequences seems to be using
native GPIOs i.e. GPIOs available in the GPU. These native GPIOs reuse
many pins that quite frankly seem scary to poke based on the VBT
sequences. We pretty much have to trust that the board is configured
such that the relevant HPD, PP_CONTROL and GPIO bits aren't used for
anything else.
MIPI sequence v4 also adds a flag to fall back to non-native sequences.
v5:
- Wrap SHOTPLUG_CTL_DDI modification in spin_lock() in icp_irq_handler()
too (Ville)
- References instead of Closes issue 6131 because this does not fix everything
v4:
- Wrap SHOTPLUG_CTL_DDI modification in spin_lock_irq() (Ville)
v3:
- Fix -Wbitwise-conditional-parentheses (kernel test robot <lkp@intel.com>)
v2:
- Fix HPD pin output set (impacts GPIOs 0 and 5)
- Fix GPIO data output direction set (impacts GPIOs 4 and 9)
- Reduce register accesses to single intel_de_rwm()

Guoqing Jiang reports that openSUSE cannot compile the kernel rpm due
to "BuildRequires: elfutils-libelf-devel" added by commit 8818039f95
("kbuild: add ability to make source rpm buildable using koji").
The relevant package name in openSUSE is libelf-devel.
Add it as an alternative package.
BTW, if it is impossible to solve the build requirement, the final
resort would be:
$ make RPMOPTS=--nodeps rpm-pkg
This passes --nodeps to the rpmbuild command so it will not verify
build dependencies. This is useful to test rpm builds on non-rpm
system. On Debian/Ubuntu, for example, you can install rpmbuild by
'apt-get install rpm'.
NOTE1:
Likewise, it is possible to bypass the build dependency check for
debian package builds:
$ make DPKG_FLAGS=-d deb-pkg
NOTE2:
The 'or' operator is supported since RPM 4.13. So, old distros such
as CentOS 7 will break. I suggest installing newer rpmbuild in such
cases.

commit 3d57e1b7b1 ("kbuild: refactor the prerequisites of the modpost
rule") moved 'vmlinux.o' inside modpost-args, possibly before some of
the other options. However, getopt() in musl libc follows POSIX and
stops looking for options upon reaching the first non-option argument.
As a result, the '-T' option is misinterpreted as a positional argument,
and the build fails:
make -f ./scripts/Makefile.modpost
scripts/mod/modpost -E -o Module.symvers vmlinux.o -T modules.order
-T: No such file or directory
make[1]: *** [scripts/Makefile.modpost:137: Module.symvers] Error 1
make: *** [Makefile:1960: modpost] Error 2
The fix is to move all options before 'vmlinux.o' in modpost-args.

Dennis Gilmore reports that the BuildID is missing in the arm64 vmlinux
since commit 994b7ac169 ("arm64: remove special treatment for the
link order of head.o").
The issue is that the type of .notes section, which contains the BuildID,
changed from NOTES to PROGBITS.
Ard Biesheuvel figured out that whichever object gets linked first gets
to decide the type of a section. The PROGBITS type is the result of the
compiler emitting .note.GNU-stack as PROGBITS rather than NOTE.
While Ard provided a fix for arm64, I want to fix this globally because
the same issue is happening on riscv since commit 2348e6bf44 ("riscv:
remove special treatment for the link order of head.o"). This problem
will happen in general for other architectures if they start to drop
unneeded entries from scripts/head-object-list.txt.
Discard .note.GNU-stack in include/asm-generic/vmlinux.lds.h.

In the case where a firmware file is too large (e.g. someone
downloaded a web page ASCII dump from github...), the firmware object
is released but the pointer is not zerod. If no other firmware file
was found then release would be called again leading to a double kfree.
Also, the size check was only being applied to the initial firmware
load not any of the subsequent attempts. So move the check into a
wrapper that is used for all loads.

The catch-all evict can fail due to object lock contention, since it
only goes as far as trylocking the object, due to us already holding the
vm->mutex. Doing a full object lock here can deadlock, since the
vm->mutex is always our inner lock. Add another execbuf pass which drops
the vm->mutex and then tries to grab the object will the full lock,
before then retrying the eviction. This should be good enough for now to
fix the immediate regression with userspace seeing -ENOSPC from execbuf
due to contended object locks during GTT eviction.
v2 (Mani)
- Also revamp the docs for the different passes.
