Compiling powerpc64 results in:
include/trace/events/timer.h:279: warning:
format '%lu' expects type 'long unsigned int', but argument 4 has type 'cputime_t'
....
cputime_t on power is u64, which triggers the above warning.
Cast the cputime_t to unsigned long long and fix the print format
string. That works on both 32 and 64 bit architectures.
While at it change the print format for long variables from %lu to %ld.

It is not quite obvious at first sight what TRACE_EVENT_TEMPLATE
does: does it define an event as well beyond defining a template?
To clarify this, rename it to DECLARE_EVENT_CLASS, which follows
the various 'DECLARE_*()' idioms we already have in the kernel:
DECLARE_EVENT_CLASS(class)
DEFINE_EVENT(class, event1)
DEFINE_EVENT(class, event2)
DEFINE_EVENT(class, event3)
To complete this logic we should also rename TRACE_EVENT() to:
DEFINE_SINGLE_EVENT(single_event)
... but in a more quiet moment of the kernel cycle.
