The motivation for this series is a change to lazy mmu handling, but this series stands on its own as a good cleanup whether or not we end up making that change. Arnd, is this something you could take through your asm-generic tree? (assuming arch maintainers are okay with it) Thanks, Nick Since v1: - Added acks and feedback from various people. - Fixed a nommu build error caught by ktp. - Dropped unicore32.
