From 05a9dff802e2ec3a2f8ab5836657ced5977fca68 Mon Sep 17 00:00:00 2001 From: kib Date: Thu, 22 Aug 2013 18:12:24 +0000 Subject: Revert r254501. Instead, reuse the type stability of the struct pmap which is the part of struct vmspace, allocated from UMA_ZONE_NOFREE zone. Initialize the pmap lock in the vmspace zone init function, and remove pmap lock initialization and destruction from pmap_pinit() and pmap_release().
