Subject: [GIT PULL] Block fixes for 3.15-rc1

Hi Linus,

A small collection of fixes that should go in before -rc1. The pull
request contains:

- A two patch fix for a regression with block enabled tagging caused by
  a commit in the initial pull request. One patch is from Martin and
  ensures that SCSI doesn't truncate 64-bit block flags, the other one
  is from me and prevents us from double using struct request queuelist
  for both completion and busy tags. This caused anything from a boot
  crash for some, to crashes under load.

- A blk-mq fix for a potential soft stall when hot unplugging CPUs with
  busy IO.

- percpu_counter fix is listed in here, that caused a suspend issue with
  virtio-blk due to percpu counters having an inconsistent state during
  CPU removal. Andrew sent this in separately a few days ago, but it's
  here. JFYI.

- A few fixes for block integrity from Martin.

- A ratelimit fix for loop from Mike Galbraith, to avoid spewing too
  much in error cases.


Please pull!
