Pull ACPI fixes from Rafael Wysocki:
 "These revert a 4.11 change that turned out to be problematic and add a
  .gitignore file.

  Specifics:

   - Revert a 4.11 commit related to the ACPI-based handling of laptop
     lids that made changes incompatible with existing user space stacks
     and broke things there (Lv Zheng).

   - Add .gitignore to the ACPI tools directory (Prarit Bhargava)"
