Merge branch 'for-3.17/core' of git://git.kernel.dk/linux-block

Pull block core bits from Jens Axboe:
 "Small round this time, after the massive blk-mq dump for 3.16.  This
  pull request contains:

   - Fixes for max_sectors overflow in ioctls from Akinoby Mita.

   - Partition off-by-one bug fix in aix partitions from Dan Carpenter.

   - Various small partition cleanups from Fabian Frederick.

   - Fix for the block integrity code sometimes returning the wrong
     vector count from Gu Zheng.

   - Cleanup an re-org of the blk-mq queue enter/exit percpu counters
     from Tejun.  Dependent on the percpu pull for 3.17 (which was in
     the block tree too), that you have already pulled in.

   - A blkcg oops fix, also from Tejun"
