Hi Linus,

These are the remaining patches I have for moving
the big kernel lock further out of the view of
developers. I had originally made them for 2.6.37
and they have been in linux-next since.

None of them has any real significance at this point,
since there are few people using the remaining modules
that require the BKL (ipx, appletalk, x.25, ufs,
adfs, hpfs, i830-drm, and a few bits in staging).
I expect to see patches for the first four in that
list at some point in the near future, after that
I suppose we can remove the option along with the
remaining dependencies completely.

For now, please pick any patches you like out of
these four.

  drm/i810: remove the BKL
  BKL: disable by default
