ACPI: PAD: fix crash in exit_round_robin()

[ Upstream commit 0a2ed70a549e61c5181bad5db418d223b68ae932 ]

ACPI: PAD: fix crash in exit_round_robin()

[ Upstream commit 0a2ed70a549e61c5181bad5db418d223b68ae932 ]

The kernel occasionally crashes in cpumask_clear_cpu(), which is called
within exit_round_robin(), because when executing clear_bit(nr, addr) with
nr set to 0xffffffff, the address calculation may cause misalignment within
the memory, leading to access to an invalid memory address.

Pull ACPI updates from Rafael Wysocki:
"These rework the handling of notifications in ACPI button drivers (to
enable future simplifications and cleanups), clean up the ACPI thermal
driver, update the ACPI backlight driver, add quirks working around
AML bugs on some systems, fix some assorted issues and clean up code.

Specifics:

- Reduce ACPI device enumeration overhead related to devices with
dependencies (Rafael Wysocki)

- Fix the handling of Microsoft LPS0 _DSM for suspend-to-idle (Mario
Limonciello)

- Fix section mismatch warning in the ACPI suspend-to-idle code (Arnd
Bergmann)

- Drop several ACPI resource management quirks related to IRQ
ovverides on AMD "Zen" systems (Mario Limonciello)

- Modify the ACPI EC driver to make it only clear the EC GPE status
when handling the GPE (Jeremy Compostella)

- Add quirks to work around ACPI tables defects on Lenovo Yoga Book
yb1-x90f/l and Nextbook Ares 8A (Hans de Goede)

- Add ACPi backlight quirks for Dell Studio 1569, Lenovo ThinkPad
X131e (3371 AMD version) and Apple iMac11,3 and stop trying to use
vendor backlight control on relatively recent systems (Hans de
Goede)

- Add pwm_lookup_table entry for second PWM on CHT/BSW devices in the
ACPI LPSS (Intel SoC) driver (Hans de Goede)

- Add nfit_intel_shutdown_status() declaration to a local header to
avoid a "missing prototypes" build warning (Arnd Bergmann)

- Clean up the ACPI thermal driver and drop some dead or otherwise
unneded code from it (Rafael Wysocki)

- Rework the handling of notifications in the ACPI button drivers so
as to allow the common notification handling code for devices to be
simplified (Rafael Wysocki)

- Make ghes_get_devices() return NULL to indicate that there are no
GHES devices so as to allow vendor-specific EDAC drivers to probe
then (Li Yang)

- Mark bert_disable() as __initdata and drop an unused function from
the APEI GHES code (Miaohe Lin)

- Make the ACPI PAD (Processor Aggregator Device) driver realize that
Zhaoxin CPUs support nonstop TSC (Tony W Wang-oc)

- Drop the certainly unnecessary and likely incorrect inclusion of
linux/arm-smccc.h from acpi_ffh.c (Sudeep Holla)"
