Subject: [PATCH 3.6.6 0/3] i82975x_edac: fatal bug fixed

This patchset fixes fatal crash caused by i82975x_edac driver.
It consists of 3 parts:
1. Move the debug code to conform to the edac_core standard
   instead of using hardcoded ifdefs. Also add some more dram
   info outputs in the debug output.
2. Cleanup the long lines and other format errors found. Use
   defines for numeric constants used repeatedly in code.
3. Fix the crash caused by wrong memory_layer initialisation
   and dimm_label initialisation. Almost total, but cleaner
   rewrite of csrow_info initialisation. And a terser error
   reporting function.
The patch has been applied to linux-3.6.6 and tested on
on Asus P5WDG2 WS Pro mobo with 7 memory configurations,
3 symmetric and 4 assymmetric:
Symmetric:
 1. 2 ECC DIMMS, one on slot A1 and other on slot B1
 2. 2 ECC DIMMS, one on slot A2 and other on slot B2
 3. 4 ECC DIMMS, mobo fully populated.
Assymmetric:
 1. 1 ECC DIMM on A1
 2. 1 ECC DIMM on B1
 3. 2 ECC DIMMS on A1 and B2
 4. 3 ECC DIMMS on A1, B2, B2
Size, label values in /sys/devices/system/edac/mc/mc0 found
consistent.
