Probably not now.  If the respective patches had kept those Kbuild files
sorted, then (most of the) conflicts would not have happened.

Maybe if there were follow up patches that put them back in order it may
help.  Or at least maybe make the conflicts different enough so that
git rerere would store them all.

I am just grumbling because I guessed this would happen when I saw the
patch go into the next-next tree (unfortunately, it was a report of mine
that caused that patch to be created :-().
