The changes for Xeon 55xx are minimal. I did some tests with the driver on it already.

I haven't the datasheets for 75xx, so I can't say for sure if it would be better to
use the same driver or to fork it.

Well, the error parsing can be done in kernel space in a standard way provided
by the edac interface.

I don't see why not the mcelog userspace shouldn't use the EDAC interface as one
of its source, getting memory errors from it, avoiding the need of re-parsing
the errors.
