[PATCH 0/2] ACPI: PM: s2idle: Prevent spurious SCIs from waking up the system

From: Rafael J. Wysocki

Hi All,

On some systems the platform generates spurious SCIs while the system is
suspended to idle and those SCIs are treated as genuine system events after
the rework of the main suspend-to-idle control flow in 5.4. The patches
here address this problem by adding a mechanism to check whether or not
SCIs generated while the system is suspended to idle are spurious and to
discard the spurious ones.

Patch [1/2] updates ACPICA to provide a way to examine the status bits of
all GPEs enabled at the moment in one go.

Patch [2/2] uses that mechanism to implement the check mentioned above.

This series is on top of https://patchwork.kernel.org/patch/11373185/ which
should appear in linux-next tomorrow.

Thanks!
