Subject: [PATCH v3 0/4] RAS: ATL: DF 4.5 NP2 Denormalization

Implement non-power-of-two denormalization for Data Fabric 4.5 in the
AMD address translation library.

Tree: git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras.git
Base commit: bd17b7c34fadef645becde1245b9394f69f31702
(origin/edac-amd-atl) 

v2:
  - Fix compilation error.
  - Make remove_base_and_hole the inverse of add_base_and_hole.
  - Move all map validation checks to validate_address_map at the
    beginning
    of translation
v3:
  - Fix bug where the legacy hole was not getting removed properly.
  - Minor rework of functions for matching the normalized address and
    logical cs fabric id.

John Allen (4):
  RAS/AMD/ATL: Read DRAM hole base early
  RAS/AMD/ATL: Expand helpers for adding and removing base and hole
  RAS/AMD/ATL: Validate address map when information is gathered
  RAS/AMD/ATL: Implement DF 4.5 NP2 denormalization
