My main point was that the interdependencies here have grown too far,
imo. The more that while having dependencies stated in the cover letter
is useful, while committing (and also reviewing) I for one would
typically only look at the individual patches.

For this patch alone, maybe it would be more obvious that said
dependency exists if it was last on the asm-generic series, rather
than part of the series here (which depends on that other series
anyway). That series now looks to be making some progress, and it being
a prereq for here it may be prudent to focus on getting that one in,
before re-posting here.
