Robert Richter de65464973 oprofile/x86: stop disabled counters in nmi handler
This patch adds checks to the nmi handler. Now samples are only
generated and counters reenabled, if the counters are running.
Otherwise the counters are stopped, if oprofile is using the nmi. In
other cases it will ignore the nmi notification.
