[PATCH v3 06/16] KVM: arm/arm64: make GIC frame address initialization model specific

Andre Przywara andre.przywara at arm.com
Wed Oct 7 07:55:16 PDT 2015


Currently we initialize all the possible GIC frame addresses in one
function, without looking at the specific GIC model we instantiate
for the guest.
As this gets confusing when adding another VGIC model later, lets
move these initializations into the respective model's emulation
init functions.
