So in this version you decided to keep the ordering of the TTBRX and
TTBRX_high bits (high being most significant). I assume this is because
of the trapping of VM registers introduced by mark and to maintain
access_vm_reg()?
Any other changes since the last version?
If none, then for the content of this patch:
