amd64_edac: add module registration routines
Also, link into Kbuild by adding Kconfig and Makefile entries. Borislav: - Kconfig/Makefile splitting - use zero-sized arrays for the sysfs attrs if not enabled - rename sysfs attrs to more conform values - shorten CONFIG_ names - make multiple structure members assignment vertically aligned - fix/cleanup comments - fix function return value patterns - fix err labels - fix a memleak bug caught by Ingo - remove the NUMA dependency and use num_k8_northbrides for initializing a driver instance per NB. - do not copy the pvt contents into the mci struct in amd64_init_2nd_stage() and save it in the mci->pvt_info void ptr instead. - cleanup debug calls - simplify amd64_setup_pci_device() Reviewed-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Doug Thompson <dougthompson@xmission.com> Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>

+ Recent Opterons (Family 10h and later) provide for Memory Error
+ Injection into the ECC detection circuits. The amd64_edac module
+ allows the operator/user to inject Uncorrectable and Correctable
+ errors into DRAM.
+
+ When enabled, in each of the respective memory controller directories
+ (/sys/devices/system/edac/mc/mcX), there are 3 input files:
+
+ - inject_section (0..3, 16-byte section of 64-byte cacheline),
+ - inject_word (0..8, 16-bit word of 16-byte section),
+ - inject_ecc_vector (hex ecc vector: select bits of inject word)
+
+ In addition, there are two control files, inject_read and inject_write,
+ which trigger the DRAM ECC Read and Write respectively.
