This is a set of simple patches to remove the big kernel
lock in some remaining areas and introduce a Kconfig
option which I'd like to have included in linux-next
and get included in the 2.6.37 merge window.

I have a total of five topic branches, which together
remove the BKL from all code except those modules
which get marked as 'depends on BKL' in the final
patch of this series.

It's fine if maintainers want to add some of these
patches to their own queue, as long as they all make
it into linux-next.

Stephen, please add
