Author: ian Date: Sun Mar 11 19:56:07 2018 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.
