  "message": "ACPI / ACPICA: Fix low-level GPE manipulation code\n\nACPICA uses acpi_ev_enable_gpe() for enabling GPEs at the low level,\nwhich is incorrect, because this function only enables the GPE if the\ncorresponding bit in its enable register\u0027s enable_for_run mask is set.\nThis causes acpi_set_gpe() to work incorrectly if used for enabling\nGPEs that were not previously enabled with acpi_enable_gpe().  As a\nresult, among other things, wakeup-only GPEs are never enabled by\nacpi_enable_wakeup_device(), so the devices that use them are unable\nto wake up the system.\n\nTo fix this issue remove acpi_ev_enable_gpe() and its counterpart\nacpi_ev_disable_gpe() and replace acpi_hw_low_disable_gpe() with\nacpi_hw_low_set_gpe() that will be used instead to manipulate GPE\nenable bits at the low level.  Make the users of acpi_ev_enable_gpe()\nand acpi_ev_disable_gpe() call acpi_hw_low_set_gpe() instead and\nmake sure that GPE enable masks are only updated by acpi_enable_gpe()\nand acpi_disable_gpe() when GPE reference counters change from 0\nto 1 and from 1 to 0, respectively.\n\nSigned-off-by: Rafael J.
