<P><FONT SIZE=2>Attached patch for supporting nsec in timer stamp and provide way to get the CPU freq</FONT>
<BR><FONT SIZE=2>We use this in our performance tests (I hope that we upload them, to the OpenIB in the near future)</FONT>
</P>
<P><FONT SIZE=2>(I left the cl_get_time_stamp_sec as is so we will not require to change old code)</FONT>
