complex? big? The big bits are dealing with renaming asm/semaphore.h to
linux/semaphore.h, and I've dropped those out now. There's a couple of
up-front patches which add inclusions of asm/semaphore.h to files which
were missing it. Then I add the new semaphore implementation, delete
the old ones, and add the down_timeout() and down_killable() functions.

Blame me for not realising that completions were semaphores under a
different name.
