By default, swarm will use calibrate_div64_gettimeoffset().  That does
not work in SMP mode because the two cores have different counter register
value.  This patch gives swarm its own and accurate gettimeoffset().

The symptom without this patch is that cpu core 1 does not have micro-second
resolution of gettimeofday().

It applies to 2.4 branch with 1 or 2 line offset warnings.  It does not apply 
to 2.5 branch. 2.5 branch appears to be outdated.
