Hi Jens,
It will be helpful to trace the iocg's whole state, including active and
idle state. And we can easily expand the original iocost_iocg_activate
trace event to support a state trace class, including active and idle
state tracing.

The do_sys_settimeofday() function uses a timespec, which is not year
2038 safe on 32bit systems.
Thus this patch introduces do_sys_settimeofday64(), which allows us to
transition users of do_sys_settimeofday() to using 64bit time types.

The conversion between struct timespec and jiffies is not year 2038
