Here are the results of different timing functions mentioned above.
I used a multi-thread(8 threads) app which calls getsid() in a loop
running on a 4-way ppc64 box. The kernel is 184.108.40.206 and
CONFIG_CPU_FREQ is set.
We tried to use different timing functions in LKET. The numbers are
average microseconds for each getsid() in all cpus.
(do_gettimeofday) (get_cycles) (_stp_gettimeofday_us)
original LKET: 4216 4045 (-4.05%) 4276 (+1.42%)
no data transfer: 3677 3526 (-4.10%) 3769 (+2.52%)
