From 5e9badadafc232a66f795183716dc2ec221a1038 Mon Sep 17 00:00:00 2001 From: kib Date: Fri, 9 Jul 2010 20:05:56 +0000 Subject: 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.
