-Subject: [PATCH 06/15] ACPI: PM: s2idle: Rework ACPI events synchronization
-
-Note that the EC GPE processing need not be synchronized in
-acpi_s2idle_wake() after invoking acpi_ec_dispatch_gpe(), because
-that function checks the GPE status and dispatches its handler if
-need be and the SCI action handler is not going to run anyway at
-that point.
-
-Moreover, it is better to drain all of the pending ACPI events
-before restoring the working-state configuration of GPEs in
-acpi_s2idle_restore(), because those events are likely to be related
-to system wakeup, in which case they will not be relevant going
-forward.
-
-Rework the code to take these observations into account.
