up to:  e3ff9c3678b4: timekeeping: Repair ktime_get_coarse*() granularity

A set of small fixes:

 - Repair the ktime_get_coarse() functions so they actually deliver what
   they are supposed to: tick granular time stamps. The current code missed
   to add the accumulated nanoseconds part of the timekeeper so the
   resulting granularity was 1 second.

 - Prevent the tracer from infinitely recursing into time getter functions
   in the arm architectured timer by marking these functions notrace

 - Fix a trivial compiler warning caused by wrong qualifier ordering.

Thanks,

        tglx
