svn commit: r358133 - head/sys/vm

New Revision: 358133
URL: https://svnweb.freebsd.org/changeset/base/358133

Log:
  Silence a gcc warning about no return from a function that handles every
  possible enum in a switch statement.  I verified that this emits nothing
  as expected on clang.  radix relies on constant propagation to eliminate
  any branching from these access routines.
