New Revision: 210996
URL: http://svn.freebsd.org/changeset/base/210996

Log:
   - Specify the HASH lookup method for the OFFPAGE uma zones used for
     pci dma allocations.  For large allocations this was done
     automatically but for small ones we need to tell UMA what to do.  This
     may be considered a UMA bug.
