Subject: [GIT PULL] ACPI fixes for v4.12-rc6

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 acpi-4.12-rc6

with top-most commit 9522933454f4c4bd5bedf3d71c538708b7c5de5b

 Merge branch 'acpica-fixes'

on top of commit 32c1431eea4881a6b17bd7c639315010aeefa452

 Linux 4.12-rc5

to receive ACPI fixes for v4.12-rc6.

These revert an ACPICA commit from the 4.11 cycle that causes
problems to happen on some systems and add a protection against
possible kernel crashes due to table reference counter imbalance.

Specifics:

 - Revert a 4.11 ACPICA change that made assumptions which are not
   satisfied on some systems and caused the enumeration of resources
   to fail on them (Rafael Wysocki).

 - Add a mechanism to prevent tables from being unmapped prematurely
   due to reference counter overflows (Lv Zheng).

Thanks!
