  Log:
  MUTEX_PROFILING has been generalized to LOCK_PROFILING. We now profile
  wait (time waited to acquire) and hold times for *all* kernel locks. If
  the architecture has a system synchronized TSC, the profiling code will
  use that - thereby minimizing profiling overhead. Large chunks of profiling
  code have been moved out of line, the overhead measured on the T1 for when
  it is compiled in but not enabled is < 1%.
