DESCRIPTION
     ddigetlbolt() returns the value of lbolt where lbolt is an
     integer  that represents the number of clock ticks since the
     last system reboot.  This value is  used  as  a  counter  or
     timer  inside  the  system kernel. The tick frequency can be
     determined  by   using   drvusectohz(9F)   which   converts
     microseconds into clock ticks.

RETURN VALUES
     ddigetlbolt() returns the value of lbolt.

CONTEXT
      This routine can be called from any context.
