mungerjiang 95a8c85b7f sli/cpu: introduce longsys check 
When a process is running in the system space, it cann't be preempted until
it return to userspace, even if the process should be reschedule and other
process was ready to run(because the server system close the kernel preempt
by default). This schedule delay may impact the performance of waiting process,
therefor we introduce the longsys check to collect the schedule delay information
of process. The longsys indication could help us spot the possible performance
jitter in the system.
