BFA_TRC_TS() calculates a 32-bit microsecond timestamp using the deprecated do_gettimeofday() function. This overflows roughly every 71 minutes, so it's obviously not used as an absolute time stamp, but it seems wrong to use a time base for it that will jump during settimeofday() calls, leap seconds, or the y2038 overflow.
This converts it to ktime_get_ts64(), which has none of those problems but is not synchronized to wall-clock time.
