[PATCH] Fix printk level on non fatal MCEs

From: Andi Kleen <ak@suse.de>

For various reasons non fatal Machine Checks can happen on Athlons (e.g.
we have reports that laptops like to trigger them on suspend/resume)

They are not necessarily fatal and often only minor hardware glitches.

But what's annoying is that they're KERN_EMERG and pollute your console and
scare the user into writing confused kernel bug reports.

This patch just replaces the KERN_EMERGs with KERN_INFO for now.  Longer
term I think it would be better to log this stuff into a separate log.
