kernel - Improve slab cleanup performance
* Convert ZoneAry[], FreeZones, and FreeOVZones from singly linked lists
to doubly linked LISTs. SLZone structure changes size but globaldata
should stay the same.
* Primarily affects slab_cleanup() which appears to be able to eat
an excessive amount of cpu on monster (systems with large amounts
of memory), and may fix a spin lock timeout panic.
* We may need some more work to moderate the amount of time slab_cleanup()
takes.
