+Subject: [PATCH] [PPC64] Fix VSX, POWER8 support, and disable POWER7.
+
+The VSX codepath is now working on POWER8 and is fully enabled.
+
+The little endian code has been verified on POWER8E, although
+a big endian machine was not available.
+
+This uses vpermxor from POWER8 to shuffle on big endian.
+
+There are a few other fixes as well to unify endian memes.
