Subject: [GIT PULL] ACPI fix for v6.4-rc8

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 acpi-6.4-rc8

with top-most commit 22db06337f590d01d79f60f181d8dfe5a9ef9085

 ACPI: sleep: Avoid breaking S3 wakeup due to might_sleep()

on top of commit 858fd168a95c5b9669aac8db6c14a9aeab446375

 Linux 6.4-rc6

to receive an ACPI fix for 6.4-rc8.

This fixes a kernel crash during early resume from ACPI S3 that has
been present since the 5.15 cycle when might_sleep() was added to
down_timeout(), which in some configurations of the kernel caused an
implicit preemption point to trigger at a wrong time.

Thanks!
