		Writing 0 to the sysfs will clear the counter, writing any other

Description:

		Use a counter for counting cycles. This is used to repurpose/dedicate

		any of the counters in the block to counting cycles. Each counter is

		represented by a bit (bit 0 for counter0, bit1 for counter1 and so on)

		and setting the corresponding bit will reserve that specific counter

		for counting cycles and override the event<N> setting.
