Yes, I will.

I've created the "for-tip" branch which is (for now) just a copy of
the current "current" branch. This branch ("for-tip") will henceforth
NEVER be rebased.

I won't guarantee this for the other branches, though; rebasing is
really handy when the patch series is to be reviewed since it cuts
down noise to the bare minimum, and avoids multiple changes to the
same area of code (which is confusing to reviewers).

I think I will append new commits to the "for-tip" branch, git-pull
new kernel -rc releases, and rebase the result into a new branch (e.g.
against-v2.6.26*). Now we have two heads which _should_ have exactly
the same content, but where one retains a strictly incremental
history, and the other is easy to read for reviewers. (And comparing
them for differences is trivial; that's just a git-diff.)
