Subject: [GIT PULL] Block core followup bits for -rc1

Hi Linus,

A few minor (but important) fixes for blk-mq for the -rc1 window.

- Hot removal potential oops fix for single queue devices. From me.

- Two merged patches in late May meant that we accidentally lost a fix
  for freeing an active queue. Fix that up. From me.

- A change of the blk_mq_tag_to_rq() API, passing in blk_mq_tags, to
  make life considerably easier for scsi-mq. From me.

- A schedule-while-atomic fix from Ming Lei, which would hit if the tag
  space was exhausted.

- Missing __percpu annotation in one place in blk-mq. Found by the magic
  Wu compile bot due to code being moved around by the previous patch,
  but it's actually an older issue. From Ming Lei.

- Clearing of tag of a flush request at end_io time. From Ming Lei.

Please pull!
