[PATCH v2 00/22] AMD64 EDAC Cleanup and Refactor

[Yazen Ghannam]

Hi Boris,

This set removes a good amount of code that is no longer useful. Also,
this set splits the module initialization more clearly between legacy
and modern systems. The original intention was to prep for adding GPU
support, but I think the split is worthwhile on its own.

Patches 1-4 remove useless code for Family 17h and later systems.

Patch 5 removes code that is no longer needed for all systems.

Patches 6-22 merge, split, and rename various functions and structures
to have clear legacy and modern initialization paths. A future patch
set will add a third "GPU" path.

The basis of the first revision of this set was to make a function
pointer for each legacy/modern split in the code path. This resulted in
16 function pointers. And, in my mind, it was still hard to follow.

The basis of this revision is to diverge early during initialization,
and then follow separate paths. This results in 7 functions pointers
including 2 used only for legacy systems and 1 used only for modern
systems. I think this is much easier to follow as each path has a clear
set of helper functions.

Also, I dropped a lot of the boiler plate commit messages. Most are now
fairly terse though I did try to add extra details in some cases.

Thanks!
