This is basically the reverse of 7c1e768974 (clockevents: prevent
clockevent event_handler ending up handler_noop, 2008-09-03). The
rationale for the latter still applies. People have been reporting
the analagous patch to this one causing hangs on resume in 3.1.y and
3.2 release candidates:
- http://thread.gmane.org/gmane.linux.kernel/1233033
- http://thread.gmane.org/gmane.linux.kernel/1233389
- http://thread.gmane.org/gmane.linux.kernel/1233159
- http://thread.gmane.org/gmane.linux.kernel/1227868/focus=1230877
So please consider reverting it for now.
Thanks,
Jonathan
