Someone else might want that and/or a complete trace.  I can see enough

you can keep him.. I don't want him back:))

I don't think it matters much.  I strongly suspect we'd just see more
of the same.  Try commenting out the current->policy |= SCHED_YIELD in
__alloc_pages() just for grins (more or less).
