Put in place the infrastructure for improved UP and SMP TLB management.
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.
