Subject: [PATCH 3.19 v2 0/3] x86, mpx: Instruction decoder fixes and hardening

Hi all-

Sorry, this is later than I had hoped to send this.  This series has
three minor fixes for mpx and the instruction decoder.

Changes from v1:
 - Dropped the TIF_IA32 change -- let's defer that until at least 3.20.
 - Fixed the MPX decode short-circuit.  v1 was buggy.
 - Patch 3 is new.  It fixes a minor regression from the MPX work.

Andy Lutomirski (3):
  x86: Fix off-by-one in the instruction decoder length checks
  x86, mpx: Short-circuit the instruction decoder for unexpected opcodes
  x86: Enforce MAX_INSN_SIZE in the instruction decoder
