Michael initially asked how these patches should merged, and as I
discussed with him on IRC, I wouldn't take them through the asm-generic
tree for 3.19 at this point, but I offered to take the ones that
are not picked up by arch maintainers through that tree for 3.20.

I also recommend to him to clarify this with maintainers of the
architectures he cares about most so they can decide whether to pick
it up or not, which triggered the message above.
