QEMU 1.6 enables using KVM READONLY memory regions. There
appears to be a bug when page tables are stored in the
READONLY memory region. To work-around this, we create
page table entries in RAM. Since RAM is present in QEMU/KVM
without any initialization, this is easily accomplished
for OVMF.
Since the firmware-device no longer needs to store 24KB of
uncompressed page table data, we also reclaim nearly all
of that for use with OVMF's compressed firmware.
