This is great! Alex, can you pull this into your tree? It's going to be very useful for POWER8 transactional memory as we have to save another set of VSX state. The changes in 4/5 are going to make coding this up a lot cleaner There are a lot of generic powerpc changes in here also. Perhaps, if Alex is fine with these, he can ACK them and benh can pull this in?
