Andre Przywara 112b0b8f8f KVM: arm/arm64: vgic: Prevent access to invalid SPIs ... In our VGIC implementation we limit the number of SPIs to a number that the userland application told us. Accordingly we limit the allocation of memory for virtual IRQs to that number. However in our MMIO dispatcher we didn't check if we ever access an IRQ beyond that limit, leading to out-of-bound accesses. Add a test against the number of allocated SPIs in check_region(). Adjust the VGIC_ADDR_TO_INT macro to avoid an actual division, which is not implemented on ARM(32).
