Ajeet,
     Sorry, by TRACER, do you mean PREEMPT_TRACER or something else? And 
what specific 2.6.X kernel were you using?

Steven, I'm seeing:
config PREEMPT_TRACER
         bool "Preemption-off Latency Tracer"
         default n
         depends on !ARCH_USES_GETTIMEOFFSET

Do you have any context as to why is !ARCH_USES_GETTIMEOFFSET flagged here?

thanks
-john
