So things have finally calmed down this past week, and I think we'll
end up with a normal release where rc7 is the last rc.
Of course, I reserve the right to change my mind in case we find
something worrisome, but on the whole it looks good. We did have some
changes that were larger than I'd like at this stage, but they were
mostly to individual drivers. Most of the commits here are trivial
one- and few-liner, with perhaps just the block layer standing out as
having a couple of bigger changes (and those are "bigger" only in
relation to the rest, not particularly big in any absolute sense).
