Author: ian Date: Sun Apr 6 00:17:41 2014 New Revision: 264183 URL: http://svnweb.freebsd.org/changeset/base/264183 Log: Add a couple more required TLB flushes. These should have been part of r264129, they are part of the overall set of changes that got several weeks of testing. I must have fumbled them while merging various patchsets.
