Ok, I also decided to just test it myself too (after applying the tty 
layer fix) and it doesn't seem to cause any problems, so I've committed 
it.

If there is dubious BKL usage that triggers the new might_sleep() warning 
(and it turns out that it's necessary and not really fixable), we can 
always just remove it again. But on the other hand, maybe it shows some 
other potential problems that should just be fixed.

We've had quite a bit of BKL work this merge-window. Maybe we'll even get 
rid of it one of these days. There are "only" about 600 instances of 
"lock_kernel()" in the tree right now ;)
