  dm: fix casting bug in dm_merge_bvec() (2015-05-29 13:41:16 -0400)

Please pull, thanks.
Mike

----------------------------------------------------------------
Quite a few fixes for DM's blk-mq support thanks to extra DM multipath
testing from Junichi Nomura and Bart Van Assche.

Also fix a casting bug in dm_merge_bvec() that could cause only a single
page to be added to a bio (Joe identified this while testing dm-cache
writeback).
