This is a part of clean up of the page table manipulation code that aims to
remove asm-generic/5level-fixup.h and asm-generic/pgtable-nop4d-hack.h

There is a single patch for both arm and arm64 because doing the conversion
separately would mean breaking the shared mmu bits in virt/kvm/arm.

Unfortunately, that's going to be really hard to merge, as the two
architectures are maintained in different trees and the breadth of this
patch series is likely to lead to conflicts in both.

But maybe this is the reason we've all been waiting for, for which we
sacrifice 32bit KVM host on the altar of progress, and finally move along.

Will and I are the only known users, and that'd be a good incentive to
experience some if this 64bit goodness... ;-)
