Sorry, what?  You can't pick this patch out of the middle of a series
and apply it!  This needs various earlier patches to work.  And then
later patches depend on this one having been applied, so if we were to
go the route of "please arch maintainers apply each of these patches",
it'd take over a year to get them all in.

As I said in the cover letter, this will all go in through the mm tree.
So what I want from arch maintainers is an Acked-by/Reviewed-by/Tested-by,
and then Andrew will apply the whole set.
