Subject[PATCH] ACPI / ACPICA: Disable GPEs during initialization
Date
From: Rafael J. Wysocki <rjw@sisk.pl>

GPEs with corresponding _Lxx/_Exx control methods need to be disabled
during initialization in case they have been enabled by the BIOS, so
that they don't fire up until they are enabled by acpi_update_gpes().
