Linus Torvalds a911dcdba1 - Significant dm-crypt CPU scalability performance improvements thanks 
to changes that enable effective use of an unbound workqueue across
   all available CPUs.  A large battery of tests were performed to
   validate these changes, summary of results is available here:
   https://www.redhat.com/archives/dm-devel/2015-February/msg00106.html
 
 - A few additional stable fixes (to DM core, dm-snapshot and dm-mirror)
   and a small fix to the dm-space-map-disk.
