[PATCH 0/3] Properly check for usable addresses on AMD

From: Yazen Ghannam

Hi all,

This set adds proper checks for usable addresses on AMD systems.

Patch 1 creates helper functions for memory error checks that will be
used in the second patch.

Patch 2 adds the proper usable address checks.

Patch 3 restructures the current usable address function to call out to
vendor-specific helpers.

I don't think these need 'stable' backports, since there isn't an urgent
issue to be fixed. But I can include 'stable' if there's interest.

Thanks,
Yazen
