Subject: [GIT PULL] ACPI support fixes for v6.18-rc6

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 acpi-6.18-rc6

with top-most commit 7564f3543cf19b1232553ab10399c9fbf514b5f3

 Merge branches 'acpi-cppc' and 'acpi-tables'

on top of commit e9a6fb0bcdd7609be6969112f3fbfcce3b1d4a7c

 Linux 6.18-rc5

to receive ACPI support fixes for 6.18-rc6.

These fix issues in the ACPI CPPC library and in the recently added
parser for the ACPI MRRM table:

 - Limit some checks in the ACPI CPPC library to online CPUs to avoid
   accessing uninitialized per-CPU variables when some CPUs are offline
   to start with, like during boot with "nosmt=force" (Gautham Shenoy)

 - Rework add_boot_memory_ranges() in the ACPI MRRM table parser to fix
   memory leaks and improve error handling (Kaushlendra Kumar)

Thanks!
