As noted in a jailhouse thread a short while ago [1,2], the presence of the
virtualization extensions implies that page table walks are coherent, and do
not require that updates are cleaned to the PoU.

These patches remove the redundant maintenance and related infrastructure.

As I do not have a suitably configured ARMv7 board, I have not been able to
test the patches myself, and any testing would be appreciated.

Having been lent a TC2 booting in Hyp mode, I've now given this a spin
with a few VMs, which I left running hackbench to fault in guest memory.

All of that ran happily.

I've tested this on TC2 and CubieTruck as well, no problems as far as I
can see.

Applied.

Thanks,
