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.
