Cover letter [PATCH v9 00/10] ftrace for MIPS

From: Wu Zhangjin <[email protected]>

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
