Merge tag 'acpi-6.6-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI fixes from Rafael Wysocki:
"These fix a general ACPI processor driver regression and an ia64 build
issue, both introduced recently.
Specifics:
- Fix recently introduced uninitialized memory access issue in the
ACPI processor driver (Michal Wilczynski)
- Fix ia64 build inadvertently broken by recent ACPI processor driver
changes, which is prudent to do for 6.6 even though ia64 support is
slated for removal in 6.7 (Ard Biesheuvel)"

ACPI: processor: Fix uninitialized access of buf in acpi_set_pdc_bits()
acpi: Provide ia64 dummy implementation of acpi_proc_quirk_mwait_check()
