Subject: [GIT PULL] ACPI fixes for v5.19-rc6

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 acpi-5.19-rc6

with top-most commit 8b356e536e69f3a4d6778ae9f0858a1beadabb1f

 ACPI: CPPC: Don't require _OSC if X86_FEATURE_CPPC is supported

on top of commit 88084a3df1672e131ddc1b4e39eeacfd39864acf

 Linux 5.19-rc5

to receive ACPI fixes for 5.19-rc6.

These fix two recent regressions related to CPPC support.

Specifics:

 - Prevent _CPC from being used if the platform firmware does not
   confirm CPPC v2 support via _OSC (Mario Limonciello).

 - Allow systems with X86_FEATURE_CPPC set to use _CPC even if CPPC
   support cannot be agreed on via _OSC (Mario Limonciello).

Thanks!
