Pull device mapper fixes from Mike Snitzer:
 "Two stable@ fixes:

   - DM thinp fix to properly advertise discard support as disabled for
     thin devices backed by a thin-pool with discard support disabled.

   - DM crypt fix to prevent the creation of bios that violate the
     underlying block device's max_segments limits.  This fixes a
     relatively long-standing NCQ SSD corruption issue reported against
     dm-crypt ever since the dm-crypt cpu parallelization patches were
     merged back in 4.0"
