Thanks Stephen.

At the moment I'm purposefully experimenting with doing arch #ifdefs
in the hope that it will lead to obvious places where the code can be
generalized even further.  I'll see how it looks before I commit down
that path though.

In the mean time, I've pushed out the current series with acked-bys
added to my git server.  I think I'm ready for things to start going
into linux-next.  Since this is the first time I've asked for a tree
to be added to linux-next, please let me know if you see anything
troublesome or problematic.  Here's the tree:

Got them, thanks.
