Subject: [PATCH] timer_stats: add core information to event counters

Hi,

This patch adds information specifying the CPU core where timer 
callbacks (events) were executed to the output of /proc/timer_stats.
I tested the patch on a dual-core x86_64 and another dual-core 
ARM board. This patch may be useful for debugging timer execution
in multi-core environments.
