The patches (all 4) look fine to me. I mean there are minor issues here and there, like s390’s tlb_flush_rmaps() that can have VM_WARN_ON(1);the generic tlb_flush_rmaps() that is missing an empty line after the ‘page' variable definition; or perhaps using __bitwise for sparse (as David pointed) — but it can all be addressed later.
