I'm afraid that would double the size of the repository (in terms of
number of commits).
One possibility is this:
git checkout 158142c2
git cherry-pick this-series~5 # patch 1
git cherry-pick this-series~2 # patch 4
git cherry-pick this-series~1 # patch 5
git merge origin/master
git checkout -p -- this-series~1 # patch 5
git commit --amend -C HEAD
git cherry-pick this-series # patch 6
Then the reverts are implicit in the merge commit.
However, this will probably still cause problems with bisection, since
the merge base between 2.2 and 2.3 will be in prehistory.

I think we can do that, provided the reimplemented functions are in
different places than the originals, so that the revert-and-reimplement
is still clear from the diff.

Ok.

I guess Maciej took care of this

I think SoftFloat-2a is more appropriate but I don't really care.

Sonuds good.
