    sys/vm               swap_pager.c swap_pager.h vm_swap.c 
  Log:
      The swap bitmap allocator was not calculating the bitmap size properly
      in the face of non-stripe-aligned swap areas.  The bug could cause a
      panic during boot.
  
      Refuse to configure a swap area that is too large (67 GB or so)
  
      Properly document the power-of-2 requirement for SWB_NPAGES.
  
      The patch is slightly different then the one Tor enclosed in the P.R.,
      but accomplishes the same thing.
