jukivili updated subscribers of D501: VPMSUMD accelleration for GCM mode on PPC.

So, things I see are needed to be done for inclusion of this patch are:

  1. GNU C coding style fixes.
  2. Adding comment about that this implementation is based on GHASH implementation by Andy Polyakov with original license. This needs to be checked with @werner , but I think following would be sufficient:

jukivili added a comment to D501: VPMSUMD accelleration for GCM mode on PPC.

When I took side-by-side comparison of cryptogams version to this patch, what I find is that they are strikingly similar. Operation/instruction ordering matches closely to parts of ghashp8-ppc.pl. In many parts variable/register names are the same also.

Ok. This was just something that I noticed while going through configure.ac. Should I make patch for this or do you want to?
