This is definitely architecture-specific, I didn't realize that anybody
else had them in use. It's fairly easy to resurrect any architecture that
needs it to have their own copy in their thread-structure.
There's another (bigger) thing that breaks other architectures, and that's
the "need_resched" flag that used to be global and now isn't (it's part of
the task structure). I didn't have time to fix up the other ports for
this, but it shoul dbe easy to do for people who are used to this, and it
makes a ton of sense both for performance and for SMP.
