Date: Tue, 13 Jan 2015 13:49:18 -0800 From: Andy Lutomirski <luto@...capital.net> To: x86@...nel.org, linux-kernel@...r.kernel.org, Dave Hansen <dave.hansen@...ux.intel.com> Cc: Masami Hiramatsu <masami.hiramatsu.pt@...achi.com>, Andy Lutomirski <luto@...capital.net> Subject: [PATCH 3.19 v4 0/2] x86, mpx: Instruction decoder fixes and hardening Hi all- Ingo and Thomas, I think this is in decent shape for x86/urgent now if you think it's appropriate to apply at this point in the cycle. Changes from v3: - Replaced MAX_INSN_SIZE with 15 in the decoder change. (Masami) I'll send the patch for 3.20 to fix MAX_INSN_SIZE separately. Changes from v2: - Dropped patch 1 (fixed in tip separately) - Fixed comment typoes in patch 2 (noticed by Dave) 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.
