Who is asking for this code? We already support hugepages for LPAE systems, so this would be targetting what? A9? I'm reluctant to add ~400 lines of subtle, low-level mm code to arch/arm/ if it doesn't have any active users. I guess I'm after some commitment that this is (a) useful to somebody and (b) going to be tested regularly, otherwise it will go the way of things like big-endian, where we end up carrying around code which is broken more often than not (although big-endian is more self-contained).
