  29   30  DESCRIPTION
  30      -       The function ddi_ffs() takes its argument and returns the shift count
  31      -       that the first (least significant) bit set in the argument corresponds
  32      -       to. The function ddi_fls() does the same, only it returns the shift
  33      -       count for the last (most significant) bit set in the argument.
       31 +     The functions ddi_ffs() and ddi_ffsll() take their argument and return
       32 +     the shift count that the first (least significant) bit set in the
       33 +     argument corresponds to.  The functions ddi_fls() and ddi_flsll() do the
       34 +     same, only they returns the shift count for the last (most significant)
       35 +     bit set in the argument.  ddi_ffs() and ddi_fls() operate on 32-bit
       36 +     values, while ddi_ffsll() and ddi_flsll() operate on 64-bit values.

  35   41  RETURN VALUES
  36      -       0
  37      -            No bits are set in mask.

       44 +     N             Bit N is the least significant (ddi_ffs(), ddi_ffsll()) or

       46 +                   Bits are numbered from 1 to 32 or 64, with bit 1 being the
       47 +                   least significant bit position and bit 32 or 64 the most
       48 +                   significant position, depending on the variant of the

  42      -            (ddi_fls) bit set in mask. Bits are numbered from  1 to  32, with
  43      -            bit 1 being the least significant bit position and bit 32 the most
  44      -            significant position.
