Contents of the series as a whole looks good to me, but I did notice a
bunch of section mismatches. Instead of commenting on the specific
ones, just compile with CONFIG_DEBUG_SECTION_MISMATCH=y and fix up the
new ones and repost, please. :)

The fixups were indeed trivial and no big deal, thanks for providing the
preferred resolutions and heads-up though.

It's no problem to add a topic branch that has dependencies and make
sure it gets merged upstream with said dependencies resolved, as long as
they are on stable branches by then (i.e. that they won't be rebased). So
either way works, it's up to you.
