Instead of that, what about something like this instead: NOTE: I
know my mailer mangles diffs and this one was hand-edited based on
Jan's diff from within my mailer so it probably doesn't apply, but
it's enough to point out the idea:

diff --fast -Ndpru linux-2.6.17-rc6~/kernel/Kconfig.hz linux-2.6.17-
