Merge tag 'acpi-4.9-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael...

Pull ACPI fixes from Rafael Wysocki:
 "Two ACPI fixes for 4.9-rc7.

  One of them reverts a recent ACPI commit that attempted to improve
  reboot/power-off on some systems, but introduced problems elsewhere,
  and the other one fixes kernel builds with the new WDAT watchdog
  driver enabled in some configurations.

  Specifics:

   - Revert the recent commit that caused the ACPI _PTS method to be
     executed in the power-off/reboot code path (as per the
     specification) in an attempt to improve things on some systems
     (apparently expecting _PTS to be executed in that code path), but
     broke power-off/reboot on at least one other machine (Rafael
     Wysocki).

   - Fix kernel builds with the new WDAT watchdog driver enabled in some
     configurations by explicitly selecting WATCHDOG_CORE when enabling
     the WDAT watchdog driver (Mika Westerberg)"
