  ACPI / PM: Fix reference counting of power resources
  Subject: [PATCH] ACPICA: Fix Scope() op in module level code
  ACPI battery: support percentage battery remaining capacity
  ACPI: Make Embedded Controller command timeout delay configurable
  ACPI dock: move some functions to .init.text
  ACPI: thermal: remove unused limit code
  ACPI: static sleep_states[] and acpi_gts_bfs_check
  ACPI: remove dead code
