Subject: [GIT PULL] ACPI fixes for v6.7-rc3

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 acpi-6.7-rc3

with top-most commit e37470624e008579fec020c6be062dd200877129

 Merge branches 'acpi-video' and 'acpi-processor' into acpi

on top of commit 98b1cc82c4affc16f5598d4fa14b1858671b2263

 Linux 6.7-rc2

to receive ACPI fixes for 6.7-rc3.

These add an ACPI IRQ override quirk for ASUS ExpertBook B1402CVA
and fix an ACPI processor idle issue leading to triple-faults in Xen
HVM guests and an ACPI backlight driver issue that causes GPUs to
misbehave while their children power is being fixed up.

Specifics:

 - Avoid powering up GPUs while attempting to fix up power for their
   children (Hans de Goede).

 - Use raw_safe_halt() instead of safe_halt() in acpi_idle_play_dead()
   so as to avoid triple-falts during CPU online in Xen HVM guests due
   to the setting of the hardirqs_enabled flag in safe_halt() (David
   Woodhouse).

 - Add an ACPI IRQ override quirk for ASUS ExpertBook B1402CVA (Hans
   de Goede).

Thanks!
