  Modified files:
    sys/sparc64/sparc64  iommu.c 
  Log:
  Small fixes for the IOMMU code:
  
  1.) Handle maximum segment sizes which are smaller than the IOMMU page
      size by splitting up pages across multiple segments if needed; this case
      was previously unimplemented, and would cause panics.
  2.) KASSERT that the physical address is in range; remove a KASSERT that
      has become pointless.
  3.) Add a comment describing what remains to be fixed in the IOMMU code;
      I plan to address these issues soon.
