CentOS - Nov 2013 - Machine check events

On my new Haswell-based machines, I am occasionally seeing entries like the
following in /var/log/messages:
	kernel: [Hardware Error]: Machine check events logged
(I would not have even noticed them, except that they get flagged by logwatch.)
These messages always occur alone, and don't seem to have a corresponding
entry in any other log file in /var/log. How can I get more info about these
messages?

Thanks,
-G.

Further investigation seems to indicate that these events should be handled
by "mcelog" or "mced". However, there is no /var/log/mcelog,
nor do I have a
"mcelog" or "mced" binary, nor does yum seem to contain
anything related
(based on "yum whatprovides '*/mcelog'" and similar queries).

Thus, I still don't know what to do with these errors.  Ignore them? I am
running 32-bit CentOS 6.4 (legacy software reasons).
