For both i386 and amd64 pmap,
- change the type of pm_active to cpumask_t, which it is; - in pmap_remove_pages(), compare with PCPU(curpmap), instead of dereferencing the long chain of pointers [1]. For amd64 pmap, remove the unneeded checks for validity of curpmap in pmap_activate(), since curpmap should be always valid after r209789. Submitted by: alc [1] Reviewed by: alc MFC after: 3 weeks
