[PATCH 0/7] BKL mass-conversion to mutex

This is one out of five topic branches in my BKL removal
series that I would like to get into linux-next as
a preparation for merging into 2.6.37.
Based on a discussion with Ingo Molnar, this series converts
many drivers that only have a single file using the BKL
to use a private mutex instead. All these patches except for
the last two have been reviewed before.
This is safe because they all use the BKL only to protect
their basic file operations and they take it as the
outermost lock. Consequently, we do not run into lock-order
problem or recursion.
Using a script that works for all these drivers gives
me reasonable confidence in the approach, since it avoids
typos and other common mistakes from sloppiness.
Stephen, please add
