[PATCH 0/2] arm{,64}/kvm: excise redundant cache maintenance

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.

Thanks,
Mark.
