[00/20] MCA Updates

Hi all,

This set is a collection of logically independent updates that make
changes to common code. I've collected them to resolve conflicts and
ordering. Furthermore, this is the first half of a larger set. The
second half is focused on refactoring the AMD MCA Thresholding feature
support. So I decided to leave out the second half for now. The second
part will include AMD CMCI Storm handling support on top of the
refactored code.

Patch 1 is a small, standalone fix for an issue I noticed during testing
of this set.

Patches 2-3 are a redo of a previous set dealing with BERT MCA decode
and preemption.

Patches 4-12 are general refactoring in preparation for later patches in
this set and the second planned set. The overall theme is to simplify
the AMD MCA init flow and to remove unnecessary data caching in per-CPU
variables. The init flow refactor will be completed in the second patch
set, since much of the cached data is used to set up MCA Thresholding.

Patches 13-14 unify the AMD THR and DFR interrupt handlers with MCA
polling.

Patch 15 is a small fix for the MCA Thresholding init path.

Patch 16 adds support for a new Corrected Error Interrupt on Scalable
MCA systems.

Patches 17-20 add support for new Scalable MCA registers and FRU Text
decoding feature. This is a follow up to a previous set.

Thanks,
