From a210080195c95ebca2a517ee3057d71607aa65e0 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Thu, 16 Sep 2010 00:30:43 +0200 Subject: ACPI / ACPICA: Defer enabling of runtime GPEs (v3) The current ACPI GPEs initialization code has a problem that it enables some GPEs pointed to by device _PRW methods, generally intended for signaling wakeup events (system or device wakeup). These GPEs are then almost immediately disabled by the ACPI namespace scanning code with the help of acpi_gpe_can_wake(), but it would be better not to enable them at all until really necessary. Modify the initialization of GPEs so that the ones that have associated _Lxx or _Exx methods and are not pointed to by any _PRW methods will be enabled after the namespace scan is complete.
