Subject: [PATCH 0/6] ACPICA: Interpreter: Improve lock order fixes

This patchset improves ACPICA intepreter lock order fixes. Including
several urgent regression fixes [PATCH 0-3].

Patches tested with customized ACPI table where _PS0/_PS3 methods are
customized to invoke a serialized control method which creates named
objects. When pm_async=yes, AE_ALREADY_EXISTS can be seen in suspend/resume
process. This is an existing issue, triggered in 4.9-rc1 by ACPICA
interpreter lock order fixes, and can be fixed by [PATCH 1] in this series.

Lv Zheng (6):
  ACPICA: Dispatcher: Fix order issue of method termination
  ACPICA: Dispatcher: Fix an unbalanced lock exit path in
    acpi_ds_auto_serialize_method()
  ACPICA: Dispatcher: Tune interpreter lock around
    acpi_ev_initialize_region()
  ACPICA: Events: Cleanup acpi_ev_initialize_region()
  ACPICA: Tables: Cleanup acpi_tb_install_and_load_table()
  ACPICA: Tables: Add acpi_tb_unload_table()
