HZ, for consistency.
So it becomes :
+static inline cycles_t get_cycles_rate(void)
+{
+ if (check_tsc_unstable())
+ return 0;
+ return (cycles_t)tsc_khz * 1000;
+}

Thanks for spotting this, will be integrated in the next release.
As a side-note, I noticed that I used CLOCK_TICK_RATE on MIPS when I
should use mips_hpt_frequency. This too will be fixed in the next
release.
