This patch series adds the initial support for POWER8 new cryptographic instructions.
Different versions of the ppc_vcipher_AES_[en|de]crypt were tested and no significant performance gains where found, even using multiple vector registers to load all sub-keys in advance. Because of that, the version included in this series was chosen based on readability. The performance gain is about 5x in a non-final hardware. The patch "perlasm/ppc-xlate.pl: vcipher instructions support" is not necessary for newer versions of GCC and I'd like to hear opinions if it's worth to include it or not. Feel free to ask me any questions regarding the code.
