Nice consolidation, I see that every architecture once had a copy of
this function, and they were all removed at one point long ago,
except for Alpha, and there is no reason to leave that one in the tree.

I'll leave it to you and Ingo to figure out what the two callers should
do, but for removing function from asm-generic:

Maybe you could split the patch into two changesets, and make the
first of them move the function to kernel/sched/rt.c, and the second
one (if we still want it then) can change the implementation to whatever
you conclude is ideal.
