In particular, replace the unused field pmap::pm_flag by pmap::pm_active, which is a bit mask representing which processors have the pmap activated. (Thus, it is a simple Boolean on UPs.) Also, eliminate an unnecessary memory reference from cpu_switch() in swtch.s. Assisted by: John S. Dyson Tested by: Luoqi Chen , Poul-Henning Kamp END
