Hi.

Added linux-pm to the cc. I think but am not sure that everyone is on
the list, but erred on the side of caution and left the cc as is.

Sure. Numbers taken from my current development tree:

Remainder of the patches: This includes arch specific support, removing
mtrr sysdev support (which will go away if/when I do hotplug cpu). Of
the 85 files, 50 are new. Some are admittedly small. That's because I've
been asked to try and separate out functionality areas into different
files. Perhaps I went overboard.

There are other patches, but they belong in the
will-go-away/should-be-merged-anyway etc category.
