[PATCH 0/5] mmu notifer debug annotations

[Daniel Vetter]

Hi all,

Next round. Changes:

- I kept the two lockdep annotations patches since when I rebased this
  before retesting linux-next didn't yet have them. Otherwise unchanged
  except for a trivial conflict.

- Ack from Peter Z. on the kernel.h patch.

- Added annotations for non_block to invalidate_range_end. I can't test
  that readily since i915 doesn't use it.

- Added might_sleep annotations to also make sure the mm side keeps up
  it's side of the contract here around what's allowed and what's not.

Comments, feedback, review as usual very much appreciated.

Cheers, Daniel
