Actually I don't have a problem taking/merging splatterpatches like
this one, as long as all relevant maintainers are cc'ed throughout. 

If they review/test/ack then great.  If they don't then their stuff
breaks during -rc and they get to fix it (this almost never happens
anyway).

If the splatterpatch is prepared as a series of patches then that's OK
as well.  I'll queue them all up behind linux-next so I can see when
maintainers have merged them and drop the individual patches as/when
needed.

On balance...  I guess individual patches is a bit better because the
more diligent maintainers will sometimes merge them and get them better
tested.  But in practice, 95% of maintainers will eyeball it, say "yeah
fine" and let Andrew handle it.
