./
* stapfuncs.5.in: Document new gettimeofday_ns.
runtime/
* time.c (stp_time_t): Use ns for the base time, and freq is now kHz.
(__stp_estimate_cpufreq): Compute kHz instead of MHz.
(__stp_time_timer_callback, __stp_init_time): Compute base in ns.
(__stp_time_cpufreq_callback): Record kHz instead of MHz.
(_stp_init_time): Record kHz, and disable preemption to avoid a race
in the cpufreq notifier.
(_stp_gettimeofday_ns): Converted from _stp_gettimeofday_us.
tapset/
* timestamp.stp (gettimeofday_ns): New function
(gettimeofday_us, gettimeofday_ms, gettimeofday_s):
Use gettimeofday_ns as the base unit.
testsuite/
* buildok/timestamp.stp: add gettimeofday_ns test.
