Ard Biesheuvel 85c8555ff0 KVM: check for !is_zero_pfn() in kvm_is_mmio_pfn() ... Read-only memory ranges may be backed by the zero page, so avoid misidentifying it a a MMIO pfn. This fixes another issue I identified when testing QEMU+KVM_UEFI, where a read to an uninitialized emulated NOR flash brought in the zero page, but mapped as a read-write device region, because kvm_is_mmio_pfn() misidentifies it as a MMIO pfn due to its PG_reserved bit being set.
