Hi,

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.

The patch is build tested and boot tested on qemu-system-{arm,aarch64}.
