int op_check_events	(	int	ctr,
		u32	event,
		u32	um,
		op_cpu	cpu_type
	)

sanity check event values

Parameters:

	ctr	counter number
	event	value for counter
	um	unit mask for counter
	cpu_type	processor type

Check that the counter event and unit mask values are allowed.

The function returns bitmask of failure cause 0 otherwise
