The operation '%' is not implemented on event-parse.c, causing
an error on the parse of events with '%' operation on its
printk format. For example,

# perf record -e sched:sched_deadline_yield ~/y
  Warning: [sched:sched_deadline_yield] unknown op '%'
....
# perf script
  Warning: [sched:sched_deadline_yield] unknown op '%'
	y  1641 [006]  3364.109319: sched:sched_deadline_yield: \
			[FAILED TO PARSE] now=3364109314595 	\
			deadline=3364139295135 runtime=19975597

This patch implements the '%' operation. With this patch, we see the
correct output:

# perf record -e sched:sched_deadline_yield ~/y
  No Warning

# perf script
	y  4005 [001]  4623.650978: sched:sched_deadline_yield: \
		now=4623.650974050				\
		deadline=4623.680957364 remaining_runtime=19979611

This patch is not dependent on the rest of the series and looks like a
good general fix.

Can you pull this one into your tree, and please add my:
