ACPICA uses acpi_hw_write_gpe_enable_reg() to re-enable a GPE after an event signaled by it has been handled. However, this function writes the entire GPE enable mask to the GPE's enable register which may not be correct. Namely, if one of the other GPEs in the same register was previously enabled by acpi_enable_gpe() and subsequently disabled using acpi_set_gpe(), acpi_hw_write_gpe_enable_reg() will re-enable it along with the target GPE. To fix this issue rework acpi_hw_write_gpe_enable_reg() so that it calls acpi_hw_low_set_gpe() with a special action value, ACPI_GPE_COND_ENABLE, that will make it only enable the GPE if the corresponding bit in its register's enable_for_run mask is set.
