[GIT PULL] core block IO bits for 3.8

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

Here are the core block IO bits for 3.8. The branch contains:

- The final version of the surprise device removal fixups from Bart.

- Don't hide EFI partitions under advanced partition types. It's fairly
  wide spread these days. This is especially dangerous for systems that
  have both msdos and efi partition tables, where you want to keep them
  in sync.

- Cleanup of using -1 instead of the proper NUMA_NO_NODE

- Export control of bdi flusher thread CPU mask and default to using the
  home node (if known) from Jeff.

- Export unplug tracepoint for MD.

- Core improvements from Shaohua. Reinstate the recursive merge, as the
  original bug has been fixed. Add plugging for discard and also fix a
  problem handling non pow-of-2 discard limits.

Please pull! There's a trivial merge in block/blk-exec.c due to a fix
that went into 3.7-rc at a later point than -rc4 where this is based.
