[PATCH 0/3] printk: Remove lockdep_off() and wakeups

These three patches rework printk() to remove the lockdep_off() hackery and
remove the need for printk() to do wakeups, which should make it much more
reliable in various contexts.

The first patch is already in -tip, the others are not. Ingo reported some
problems with #2, but I've been unable to reproduce so far.

The third patch has the semaphore trickery in and keeps it private to printk.c
as per Thomas' request.

A kernel with all three applied and lockdep enabled seems to have no problem
booting.
