From: Yazen Ghannam <yazen.ghannam@amd.com>
The focus of this patchset is define and use the MCA bank structures and bank count per logical CPU.
With the exception of patch 4, this set applies to systems in production today.
Patch 1: Moves the declaration of struct mce_banks[] to the only file it's used.
Patch 2: Splits struct mce_bank into a structure for fields common to MCA banks on all CPUs and another structure that can be used per_cpu.
Patch 3: Brings full circle the saga of the threshold block addresses on SMCA systems. After taking a step back and reviewing the AMD documentation, I think that this implimentation is the simplest and more robust way to follow the spec.
Patch 4: Saves and uses the MCA bank count as a per_cpu variable. This is to support systems that have MCA bank counts that are different between logical CPUs.
Patch 5: Checks if an MCA banks is enabled after initialization.

Thanks, Yazen
