From: Wu Zhangjin <wuzhangjin@xxxxxxxxx>
After getting the feedback of v8 revision from Thomas, I have written a
cnt3_to_63() based sched_clock() for MIPS and send it out as a standalone
patch("MIPS: Add a high precision sched_clock() via cnt32_to_63()").
This v9 revision only reserve the Ftrace parts. So, Steven or Ralf, Is it time
to apply it? Thanks!
Best Regards,
Wu Zhangjin
