Author: nwhitehorn Date: Fri Apr 6 16:00:37 2012 New Revision: 233948 URL: http://svn.freebsd.org/changeset/base/233948 Log: Give the kernel pmap lock a different name than user pmap locks. It has (slightly) different semantics and renaming it prevents a (harmless) WITNESS warning during bootup for 32-bit kernels on 64-bit CPUs.
