    Pull CSD-lock update from Paul McKenney:
     "This switches from sched_clock() to ktime_get_mono_fast_ns(), which on
      x86 switches from the rdtsc instruction to the rdtscp instruction,
      thus avoiding instruction reorderings that cause false-positive
      reports of CSD-lock stalls of almost 2^46 nanoseconds. These false
      positives are rare, but really are seen in the wild"
