New Revision: 330782
URL: https://svnweb.freebsd.org/changeset/base/330782

Log:
  Remove MTX_NOPROFILE from atrtc_lock, it was inappropriately copy/pasted
  from the i8254 driver when I created separate mutexes for each.  The i8254
  driver could be the active timecounter, leading to recursion during mutex
  profiling, but the atrtc driver cannot be a timecounter, so it isn't needed.
