  dm crypt: constrain crypt device's max_segment_size to PAGE_SIZE (2015-09-14 12:04:24 -0400)

Please pull, thanks.

----------------------------------------------------------------
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.
