Merge tag 'kvmarm-fixes-6.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

KVM/arm64 fixes for 6.12, take #1

- Fix pKVM error path on init, making sure we do not change critical
system registers as we're about to fail

- Make sure that the host's vector length is at capped by a value
common to all CPUs

- Fix kvm_has_feat*() handling of "negative" features, as the current
code is pretty broken

- Promote Joey to the status of official reviewer, while James steps
down -- hopefully only temporarly

ASoC: Fixes for v6.12

A bunch of fixes here that came in during the merge window and the first
week of release, plus some new quirks and device IDs. There's nothing
major here, it's a bit bigger than it might've been due to there being
no fixes sent during the merge window due to your vacation.

ACPI: sysfs: manage attributes as attribute_group

The current manual attribute management is inconsistent and brittle.

Not all return values of device_create_file() are checked and the
cleanup logic needs to be kept up to date manually.

Moving all attributes into an attribute_group and using the is_visible()
callback allows the management of all attributes as a single unit.

ACPI: sysfs: evaluate _STR on each sysfs access

The handling of the _STR method is inconsistent with the other method
evaluations. It is the only method which is cached.

The cached value stored in 'struct acpi_device_pnp' has a different
lifetime than the other struct members.

Commit d1efe3c324ea ("ACPI: Add new sysfs interface to export device description")
does not explain this difference.

Evaluating the method every time also removes the necessity to manage
the lifetime of the cached value, which would be a problem when managing
the sysfs attributes through the device core.

Merge tag 'acpi-6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI updates from Rafael Wysocki:
"These fix issues, add new quirks, rearrange the IRQ override quirk
definitions, add new helpers and switch over code to using them,
rework a couple of interfaces to be more flexible, eliminate strncpy()
usage from PNP, extend the ACPI PCC mailbox driver and clean up code.

This is based on ACPI thermal driver changes that are present in the
thermal control updates for 6.7-rc1 pull request (they are depended on
by the ACPI utilities updates). However, the ACPI thermal driver
changes are not included in the list of specific ACPI changes below.

Specifics:

- Add symbol definitions related to CDAT to the ACPICA code (Dave
Jiang)

- Use the acpi_device_is_present() helper in more places and rename
acpi_scan_device_not_present() to be about enumeration (James
Morse)

- Add __printf format attribute to acpi_os_vprintf() (Su Hui)

- Clean up departures from kernel coding style in the low-level
interface for ACPICA (Jonathan Bergh)

- Replace strncpy() with strscpy() in acpi_osi_setup() (Justin Stitt)

- Fail FPDT parsing on zero length records and add proper handling
for fpdt_process_subtable() to acpi_init_fpdt() (Vasily Khoruzhick)

- Rework acpi_handle_list handling so as to manage it dynamically,
including size computation (Rafael Wysocki)

- Clean up ACPI utilities code so as to make it follow the kernel
coding style (Jonathan Bergh)

- Consolidate IRQ trigger-type override DMI tables and drop .ident
values from dmi_system_id tables used for ACPI resources management
quirks (Hans de Goede)

- Add ACPI IRQ override for TongFang GMxXGxx (Werner Sembach)

- Allow _DSD buffer data only for byte accessors and document the
_DSD data buffer GUID (Andy Shevchenko)

- Drop BayTrail and Lynxpoint pinctrl device IDs from the ACPI LPSS
driver, because it does not need them (Raag Jadav)

- Add acpi_backlight=vendor quirk for Toshiba Portégé R100 (Ondrej
Zary)

- Add "vendor" backlight quirks for 3 Lenovo x86 Android tablets
(Hans de Goede)

- Move Xiaomi Mi Pad 2 backlight quirk to its own section (Hans de
Goede)

- Annotate struct prm_module_info with __counted_by (Kees Cook)

- Fix AER info corruption in aer_recover_queue() when error status
data has multiple sections (Shiju Jose)

- Make APEI use ERST maximum execution time for slow devices (Jeshua
Smith)

- Add support for platform notification handling to the PCC mailbox
driver and modify it to support shared interrupts for multiple
subspaces (Huisong Li)

- Define common macros to use when referring to various bitfields in
the PCC generic communications channel command and status fields
and use them in some drivers (Sudeep Holla)

- Add EC GPE detection quirk for HP 250 G7 Notebook PC (Jonathan
Denose)

- Fix and clean up create_pnp_modalias() and create_of_modalias()
(Christophe JAILLET)

- Modify 2 pieces of code to use acpi_evaluate_dsm_typed() (Andy
Shevchenko)

- Define acpi_dev_uid_match() for matching _UID and use it in several
places (Raag Jadav)

- Use acpi_device_uid() for fetching _UID in 2 places (Raag Jadav)

- Add context argument to acpi_dev_install_notify_handler() (Rafael
Wysocki)

- Clarify ACPI bus concepts in the ACPI device enumeration
documentation (Rafael Wysocki)

- Switch over the ACPI AC and ACPI PAD drivers to using the platform
driver interface which, is more logically consistent than binding a
driver directly to an ACPI device object, and clean them up (Michal
Wilczynski)

- Replace strncpy() in the PNP code with either memcpy() or strscpy()
as appropriate (Justin Stitt)

- Clean up coding style in pnp.h (GuoHua Cheng)"

to be nul-terminated, so remove the unneeded (but harmless) writes of a
trailing '\0' to it.

Also snprintf() never returns negative values, so remove redundant (but
harmless) checks for it.

ACPI: sysfs: Fix create_pnp_modalias() and create_of_modalias()

snprintf() does not return negative values on error.

To know if the buffer was too small, the returned value needs to be
compared with the length of the passed buffer. If it is greater or
equal, the output has been truncated, so add checks for the truncation
to create_pnp_modalias() and create_of_modalias(). Also make them
return -ENOMEM in that case, as they already do that elsewhere.

Moreover, the remaining size of the buffer used by snprintf() needs to
be updated after the first write to avoid out-of-bounds access as
already done correctly in create_pnp_modalias(), but not in
create_of_modalias(), so change the latter accordingly.
