Rafael J. Wysocki f6502ce4f0 ACPICA: Clear status of GPEs on first direct enable 
[ Upstream commit 44758bafa53602f2581a6857bb20b55d4d8ad5b2 ]

ACPI GPEs (other than the EC one) can be enabled in two situations.
First, the GPEs with existing _Lxx and _Exx methods are enabled
implicitly by ACPICA during system initialization.  Second, the
GPEs without these methods (like GPEs listed by _PRW objects for
wakeup devices) need to be enabled directly by the code that is
going to use them (e.g. ACPI power management or device drivers).

In the former case, if the status of a given GPE is set to start
with, its handler method (either _Lxx or _Exx) needs to be invoked
to take care of the events (possibly) signaled before the GPE was
enabled.  In the latter case, however, the first caller of
acpi_enable_gpe() for a given GPE should not be expected to care
about any events that might be signaled through it earlier.  In
that case, it is better to clear the status of the GPE before
enabling it, to prevent stale events from triggering unwanted
actions (like spurious system resume, for example).

For this reason, modify acpi_ev_add_gpe_reference() to take an
additional boolean argument indicating whether or not the GPE
status needs to be cleared when its reference counter changes from
zero to one and make acpi_enable_gpe() pass TRUE to it through
that new argument.
