Use ia64_fetchadd() instead of atomic_dec_return()

Arthur Othieno 727a53bd53 [PATCH] semaphore: Remove __MUTEX_INITIALIZER()
__MUTEX_INITIALIZER() has no users, and equates to the more commonly used
DECLARE_MUTEX(), thus making it pretty much redundant.  Remove it for good.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
