Subject: [GIT PULL] Urgent ACPI support fix for v6.18

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 acpi-6.18-rc8

with top-most commit 43ff36c4a5a574ee83b4b0d3f3d74f09a3a8c2d3

 Revert "ACPI: processor: idle: Optimize ACPI idle driver registration"

on top of commit ac3fd01e4c1efce8f2c054cdeb2ddd2fc0fb150d

 Linux 6.18-rc7

to receive an urgent ACPI support fix for 6.18.

This reverts a commit that attempted to make the code in the ACPI
processor driver more straightforward, but it turned out to cause
the kernel to crash on at least one system, along with some further
cleanups on top of it.

Thanks!
