    Subject[PATCH 2/3] x86: Add VIA processor instructions in opcodes decoder
    Date
    From: Masami Hiramatsu <mhiramat@redhat.com>

    Add VIA processor's Padlock instructions(MONTMUL, XSHA1, XSHA256)
    as parts of the kernel may use them.

    This fixes the following crash in opcodes decoder selftests:

    make[2]: `scripts/unifdef' is up to date.
    TEST posttest
    Error: c145cf71: f3 0f a6 d0 repz xsha256
    Error: objdump says 4 bytes, but insn_get_length() says 3 (attr:0)
    make[1]: *** [posttest] Error 2
    make: *** [bzImage] Error 2
