Right, that was a mistake on my end, I just cut too much, see below
for the missing shortlog.

Regarding a possible revert, that would indeed involve reverting
multiple patches for most architectures, plus parts of at least these
three:

  Documentation: arch-support: remove obsolete architectures
  treewide: simplify Kconfig dependencies for removed archs
  ktest: remove obsolete architectures

For those, I went the other way, and removed all architectures at
once to simplify my work and to avoid touching the same files up
to eight times with interdependent patches (which couldn't
be reverted without conflicts either).

There are a couple of driver removal patches that got picked up
into subsystem trees instead of this tree, so a full revert would also
involve finding other drivers, but if you prefer to have the patches
completely split up by arch, I could rework the series that way.
