Use ktime_get_ts() to take the timestamp instead of getnstimestamp(). This
patch prepares to remove getnstimestamp() by switching its only user to a
different function with almost exactly the same code.

The parameter to put_cpu_var() is unreferenced by the implementation, and
the compiler doesn't try to comprehend comments, so this wouldn't cause any
problem, but if bugged me enough to post a fix :-)

This adds a timestamp field to the events sent via the process event
connector. The timestamp allows listeners to accurately account the
duration(s) between a process' events and offers strong means with which
to determine the order of events with respect to a given task while also
avoiding the addition of per-task data.
This alters the size and layout of the event structure and hence would
break compatibility if process events connector as it stands in 2.6.15-rc2
were released as a mainline kernel.

This patch adds a connector that reports fork, exec, id change, and exit
events for all processes to userspace. It replaces the fork_advisor patch
that ELSA is currently using. Applications that may find these events
useful include accounting/auditing (e.g. ELSA), system activity monitoring
(e.g. top), security, and resource management (e.g. CKRM).
