[PATCH] treewide: Convert clockevents_notify to use int cpu
From: Joe Perches
Date: Wed Dec 10 2014 - 18:29:05 EST
As far as I can tell, there's no value indirecting
the cpu passed to this function via a void *.
Update all the callers and called functions from within
clockevents_notify.
Miscellanea:
Add pr_fmt and convert one printk(KERN_ERR to pr_err
