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.
