From: Maxime Ripard <maxime.rip...@free-electrons.com> The sched_clock we use on some system is this timer, and since we started using cpufreq, the cpu clock (that is one of the timer's clock indirect parent) now changes, along with the actual sched_clock rate. We can safely remove the sched_clock on those systems, since we have other reliable sched_clock in the system.
