Subject: [GIT PULL] Make the block layer great again

Hi Linus,

Basically three amazing fixes in this pull request, split into 4
patches. Believe me, they should go into 4.4. Two of them fix a
regression, the third and last fixes an easy-to-trigger bug.

- Fix a bad irq enable through null_blk, for queue_mode=1 and using
  timer completions. Add a block helper to restart a queue
  asynchronously, and use that from null_blk. From me.

- Fix a performance issue in NVMe. Some devices (Intel Pxxxx) expose a
  stripe boundary, and performance suffers if we cross it. We took that
  into account for merging, but not for the newer splitting code. Fix
  from Keith.

- Fix a kernel oops in lightnvm with multiple channels. From Matias.

Please pull!
