From e4f308bbf9f360ee2af5b94b87aef170d8f20dc4 Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Fri, 13 Dec 2013 17:22:06 +0100 Subject: acpi: piix4: remove not needed GPE0 mask Hardcoded GPE0 mask isn't really needed. Since GPE0_STS initialized with all bits cleared and only QEMU itself can set bits there (i.e. guest can only clear bits in it). So guest can't triger SCI by setting _STS & _EN bits and there is not reason to mask out not supported _STS bits since they shouldn't be set by QEMU in the first place.
