Thomas Gleixner e3ff9c3678 timekeeping: Repair ktime_get_coarse*() granularity ... Jason reported that the coarse ktime based time getters advance only once per second and not once per tick as advertised. The code reads only the monotonic base time, which advances once per second. The nanoseconds are accumulated on every tick in xtime_nsec up to a second and the regular time getters take this nanoseconds offset into account, but the ktime_get_coarse*() implementation fails to do so. Add the accumulated xtime_nsec value to the monotonic base time to get the proper per tick advancing coarse tinme.
