  SVN rev 212663 on 2010-09-15 15:18:41Z by marius
  
  - Update the comment in swi_vm() regarding busdma bounce buffers; it's
    unlikely that support for these ever will be implemented on sparc64 as
    the IOMMUs are able to translate to up to the maximum physical address
    supported by the respective machine, bypassing the IOMMU is affected
    by hardware errata and being able to support DMA engines which cannot
    do at least 32-bit DMA does not justify the costs.
  - The page zeroing in uma_small_alloc() may use the VIS-based block zero
    function so take advantage of it.
