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
