Subject: KVM: arm/arm64: GICv4: Handle CLEAR applied to a VLPI
Patch-mainline: v4.15-rc1
Git-commit: fb0cada604fcda82813f654b0d95963ee165770f
References: bsc#1077761
Handling CLEAR is pretty easy. Just ask the ITS driver to clear
the corresponding pending bit (which will turn into a CLEAR
command on the physical side).
