  ACPICA: Events: Introduce ACPI_GPE_DISPATCH_RAW_HANDLER to fix 2 issues for the current GPE APIs
  ACPICA: Update version to 20150204
  ACPICA: Update Copyright headers to 2015
  ACPICA: Hardware: Cast GPE enable_mask before storing
  ACPICA: Events: Cleanup GPE dispatcher type obtaining code
  ACPICA: Events: Cleanup to move acpi_gbl_global_event_handler invocation out of acpi_ev_gpe_dispatch()
  ACPICA: Events: Cleanup of resetting the GPE handler to NULL before removing
  ACPICA: Events: Fix uninitialized variable
  ACPICA: Events: Remove acpi_ev_valid_gpe_event() due to current restriction
  ACPICA: Events: Remove duplicated sanity check in acpi_ev_enable_gpe()
  ACPICA: Events: Back port "ACPICA: Save current masks of enabled GPEs after enable register writes"
  ACPICA: Resources: Provide common part for struct acpi_resource_address structures.
  ACPI: Introduce acpi_unload_parent_table() usages in Linux kernel
  ACPICA: take ACPI_MTX_INTERPRETER in acpi_unload_table_id()
