[PATCH 2/3] x86: Add VIA processor instructions in opcodes decoder

[Frederic Weisbecker <fweisbec@gmail.com>]

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
