mcelog logs them. The kernel shouldn't be spewing these messages
at all, especially not for corrected errors (this is a still 
unfixed regression for Intel CPUs)

Here's an older fix:

http://git.kernel.org/?p=linux/kernel/git/ak/linux-mce-2.6.git;a=commit;h=6e3c7411d2b86bff210c59caa432e8e862037bfd

They are already logged, no need to do anything further.
