ACPICA uses acpi_ev_enable_gpe() for enabling GPEs at the low level, which is incorrect, because this function only enables the GPE if the corresponding bit in its enable register's enable_for_run mask is set. This causes acpi_set_gpe() to work incorrectly if used for enabling GPEs that were not previously enabled with acpi_enable_gpe(). As a result, among other things, wakeup-only GPEs are never enabled by acpi_enable_wakeup_device(), so the devices that use them are unable to wake up the system. To fix this issue remove acpi_ev_enable_gpe() and its counterpart acpi_ev_disable_gpe() and replace acpi_hw_low_disable_gpe() with acpi_hw_low_set_gpe() that will be used instead to manipulate GPE enable bits at the low level. Make the users of acpi_ev_enable_gpe() and acpi_ev_disable_gpe() call acpi_hw_low_set_gpe() instead and make sure that GPE enable masks are only updated by acpi_enable_gpe() and acpi_disable_gpe() when GPE reference counters change from 0 to 1 and from 1 to 0, respectively.
