Hi Linus,
This goes early for your convenience.
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
acpi-7.2-rc1
with top-most commit 615f90d3b1b7900d591a9162793f616b051f07b8
Merge branches 'acpi-processor', 'acpi-cppc' and 'acpi-pci'
on top of commit 4549871118cf616eecdd2d939f78e3b9e1dddc48
Linux 7.1-rc7
to receive ACPI support updates for 7.2-rc1.
These update the ACPICA code in the kernel to upstream version 20260408,
introduce support for devres-based management of ACPI notify handlers
and update some core ACPI device drivers on top of that (which includes
some fixes and cleanups), add _DEP support for PCI/CXL roots and Intel
CVS devices, fix a couple of assorted issues and clean up code:
- Fix multiple issues related to probe, removal and missing NVDIMM
device notifications in the ACPI NFIT driver (Rafael Wysocki)
- Add support for devres-based management of ACPI notify handlers to
the ACPI core (Rafael Wysocki)
- Switch multiple core ACPI device drivers (including the ACPI PAD,
ACPI video bus, ACPI HED, ACPI thermal zone, ACPI AC, ACPI battery,
and ACPI NFIT drivers) over to using devres-based resource management
during probe (Rafael Wysocki)
- Replace mutex_lock/unlock() with guard()/scoped_guard() in the ACPI
PMIC driver (Maxwell Doose)
- Fix message kref handling in the dead device path of the ACPI IPMI
address space handler (Yuho Choi)
- Use sysfs_emit() in idlecpus_show() in the ACPI processor aggregator
device (PAD) driver (Yury Norov)
- Clean up device_id_scheme initialization in the ACPI video bus driver
(Jean-Ralph Aviles)
- Clean up lid handling in the ACPI button driver and
acpi_button_probe(), reorganize installing and removing event
handlers in that driver and switch it over to using devres-based
resource management during probe (Rafael Wysocki)
- Add support for the Legacy Virtual Register (LVR) field in I2C serial
bus resource descriptors to ACPICA (Akhil R)
- Fix multiple issues related to bounds checks, input validation,
use-after-free, and integer overflow checks in the AML interpreter
in ACPICA (ikaros)
- Update the copyright year to 2026 in ACPICA files and make minor
changes related to ACPI 6.6 support (Pawel Chmielewski)
- Remove spurious precision from format used to dump parse trees in
ACPICA (David Laight)
- Add modern standby DSM GUIDs to ACPICA header files (Daniel Schaefer)
- Fix FADT 32/64X length mismatch warning in ACPICA (Abdelkader Boudih)
- Update D3hot/cold device power states definitions in ACPICA header
files (Aymeric Wibo)
- Fix NULL pointer dereference in acpi_ns_custom_package() (Weiming
Shi)
- Update ACPICA version to 20260408 (Saket Dumbre)
- Add cpuidle driver check in acpi_processor_register_idle_driver() to
avoid evaluating _CST unnecessarily (Tony W Wang-oc)
- Suppress UBSAN warning caused by field misuse during PCC-based
register access in the ACPI CPPC library (Jeremy Linton)
- Add support for CPPC v4 to the ACPI CPPC library (Sumit Gupta)
- Update the ACPI device enumeration code to honor _DEP for ACPI0016
PCI/CXL host bridges and make the ACPI PCI root driver clear _DEP
dependencies for PCI roots that have become operational (Chen Pei)
Thanks!
