This takes care of remaining reasons for QEMU to access /dev/mem, but also the Intel Wifi card violating spec by putting some registers on the same page as the MSI-X table. Besides the stubdomain case (of which I care more), this is also necessary for PCI-passthrough to work with lockdown enabled in dom0 (when QEMU runs in dom0). See individual patches for details. This series include also tests for MSI-X using new approach (by preventing QEMU access to /dev/mem). But for it to work, it needs QEMU change that makes use of the changes introduced here.
