PR 2922
* time.c (_stp_init_time): call cpufreq_get for each cpu from
a non-atomic context (module init time).
* time.c (__stp_init_time): remove call to cpufreq_get from IPI.
* time.c (__stp_time_timer_callback): disable IRQ's to avoid
perturbations in measurements.
* time.c (_stp_gettimeofday_us): disable preemption to avoid CPU
swaps while we're computing the time.
