Merge third patch-bomb from Andrew Morton:
 "We're pretty much done over here - I'm still waiting for a nouveau
  merge so I can cleanly finish up Christoph's dma-mapping rework.

   - bunch of small misc stuff

   - fold abs64() into abs(), remove abs64()

   - new_valid_dev() cleanups

   - binfmt_elf_fdpic feature work"
