commit f2c5d4ab43eb3300236045f944aa0021db095c53 Author: Matthew Dillon <dillon@apollo.backplane.com> Date: Wed Oct 26 14:46:52 2011 -0700 kernel - Handle pmap_protect() race in pmap code * If we find an unexpectedly non-NULL pte_pv from a pv_find(), which only holds the pv, we have to resolve a locked pte_pv to rectify the race. Add debug code to catch and rectify the situation.
