This is used by gdbstub.
If there's a way for kvm to convert a virtual address to a physical address
using the hardware, then use that. I suspect there is not.
Otherwise, you have to keep all of the mmu page table walking stuff for kvm as
well as tcg. Which probably means that all of the other stuff that you're
stubbing out is used or usable as well.
