OK, it looks like the "misc" misc drivers patch can go into the
bkl-removal tree, while the watchdog patches should not.  What that
means, I guess, is that the final misc_open() patch cannot go in at this
point; Alan's watchdog stuff needs to find its way in first.  Make
sense?

Alas, I have no such script.  I just committed each change as I made it
- each one required individual attention anyway.  The misc changes look
pretty straightforward, so I could probably hack up such a thing pretty
quickly if you don't have a tree with broken out patches.

Thanks,
