  SVN rev 194454 on 2009-06-18 17:59:04Z by alc
  
  Utilize the new function kmem_alloc_contig() to implement the UMA back-end
  allocator for the jumbo frames zones.  This change has two benefits: (1) a
  custom back-end deallocator is no longer required.  UMA's standard
  deallocator suffices. (2) It eliminates a potentially confusing artifact
  of using contigmalloc(): The malloc(9) statistics contain bogus information
  about the usage of jumbo frames.  Specifically, the malloc(9) statistics
  report all jumbo frames in use whereas the UMA zone statistics report the
  "truth" about the number in use vs. the number free.
