      Alright, this one is only triggered when slab debugging is enabled.  The
      slabs are assumed to be aligned on a HUGEPTE_TABLE_SIZE boundary.  The free
      path makes use of this assumption and uses the lowest nibble to pass around
      an index into an array of kmem_cache pointers.  With slab debugging turned
      on, the slab is still aligned, but the "working" object pointer is not.
      This would break the assumption above that a full nibble is available for
      the PGF_CACHENUM_MASK.
      
      The following patch reduces PGF_CACHENUM_MASK to cover only the two least
      significant bits, which is enough to cover the current number of 4 pgtable
      cache types.  Then use this constant to mask out the appropriate part of
      the huge pte pointer.
