Rafael J. Wysocki 28f4f8a9de ACPI / ACPICA: Fix reference counting problems with GPE handlers ... If a handler is installed for a GPE associated with an AML method and such that it cannot wake up the system from sleep states, the GPE remains enabled after the handler has been installed, although it should be disabled in that case to avoid spurious execution of the handler. Fix this issue by making acpi_install_gpe_handler() disable GPEs that were previously associated with AML methods and cannot wake up the system from sleep states. Analogously, make acpi_remove_gpe_handler() enable the GPEs that are associated with AML methods after their handlers have been removed and cannot wake up the system from sleep states. In addition to that, fix a code ordering issue in acpi_remove_gpe_handler() that renders the locking ineffective (ACPI_MTX_EVENTS is released temporarily in the middle of the routine to wait for the completion of events already in progress). For this purpose introduce acpi_raw_disable_gpe() and acpi_raw_enable_gpe() to be called with acpi_gbl_gpe_lock held and rework acpi_disable_gpe() and acpi_enable_gpe(), respectively, to use them. Also rework acpi_gpe_can_wake() to use acpi_raw_disable_gpe() instead of calling acpi_disable_gpe() after releasing the lock to avoid the possible theoretical race with acpi_install_gpe_handler().
