This patchset fixes regressions in ACPICA intepreter lock order improvement.
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.
v2: 1. Remove non-regression-fixes. 2. Add "Fixes" tags.
Lv Zheng (3): 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()
