commit 9370a8d717720f6b17221490fea8d798396d9f2f
Author: Mauro Carvalho Chehab <mchehab@redhat.com>
Date: Mon Oct 15 21:49:35 2012 -0300
i82975x_edac: Use the edac standard debug macro
Instead of declaring its own debug macro, that requires
to uncomment part of the code, use the edac standard macro
to add the debug code, and the edac debug level to print it,
just like any other EDAC driver.

i82975x_edac: Fix dimm label initialization
The driver has only 4 hardcoded labels, but allows much more memory.
Fix it by removing the hardcoded logic, using snprintf() instead.

i82975x_edac: rewrite the entire fill/report logic
There are so many bugs at the fill/error report logic that
the code ended by being re-written.
Issues solved:
- DIMM labels were "randomly" filled: they won't
match the memory layout, due to a series of bugs on it;
- The memory controller supports 3 different modes:
single, dual interleaved and dual async. The logic there were
written considering the dual interleaved one (yet, some
single mode support was there);
- The boundary limit to decide on each channel the error happens,
at dual interleaved mode, is given by bit 6 of the error address,
and not bit 1. The practical effect is that Corrected errors
will have a 50% of chance of pointing to the right DIMM. Only
the DIMM pair logic were OK;
- The asymetric mode weren't properly supported. The driver would
handle an asymetric mode as 'single mode', with doesn't actually
match it, creating some weird real/virtual DIMM mappings.
- Some other random bugs got fixed.
Tested on a Dell Precision N390, on dual interleaved mode.
