Rafael J. Wysocki f941d3e41d ACPI: EC / PM: Disable non-wakeup GPEs for suspend-to-idle 
There are systems in which non-wakeup GPEs fire during the "noirq"
suspend stage of suspending devices and that effectively prevents the
system that tries to suspend to idle from entering any low-power
state at all.  If the offending GPE fires regularly and often enough,
the system appears to be suspended, but in fact it is in a tight loop
over "noirq" suspend and "noirq" resume of devices all the time.

To prevent that from happening, disable all non-wakeup GPEs except
for the EC GPE for suspend-to-idle (the EC GPE is special, because
on some systems it has to be enabled for power button wakeup events
to be generated as expected).

Fixes: 147a7d9d25 (ACPI / PM: Do not reconfigure GPEs for suspend-to-idle)
