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.

ACPICA: Dispatcher: Fix an unbalanced lock exit path in
acpi_ds_auto_serialize_method()
ACPICA: Dispatcher: Tune interpreter lock around
