svn commit: r256068 - head/sys/kern

[Alan Cox]

New Revision: 256068
URL: http://svnweb.freebsd.org/changeset/base/256068

Log:
  Tidy up kmeminit(): Since r245575, 'nmbclusters' is calculated after
  kmeminit() runs, so it contributes nothing to 'vm_kmem_size'; update a
  comment to reflect that r254025 replaced the kmem submap with the kmem
  arena.
