Subject: [PATCH v2 0/8] AMD MCA Address Translation Updates

From: Yazen Ghannam <yazen.ghannam@....com>

This patchset includes updates for the MCA Address Translation process
on recent AMD systems.

Patches 1 & 3:
Fixes an input to the address translation function. The translation
requires a physical Die ID (NodeId in AMD documentation) rather than a
logicial NUMA node ID. This is because the physical and logical nodes
may not always match.

Patch 2:
Removes a function that is no longer needed with Patch 1.

Patches 4-7:
Code cleanup in preparation for Patch 8.

Patch 8:
Add translation support for new memory interleaving options available in
Rome systems. The patch is based on the latest AMD reference code for
the address translation.

Patches 6-8 have checkpatch warnings about long lines, but I kept the
long lines for readability.

Thanks,
Yazen

v1 -> v2:
* Save the AMD NodeId value in struct cpuinfo_x86 rather than use a
  local value in MCA code.
* Include code cleanup for AMD MCA Address Translation function before
  adding new functionality.

Muralidhara M K (1):
  x86/MCE/AMD Support new memory interleaving modes during address
    translation

Yazen Ghannam (7):
  x86/CPU/AMD: Save NodeId on AMD-based systems
  x86/CPU/AMD: Remove amd_get_nb_id()
  EDAC/mce_amd: Use struct cpuinfo_x86.node_id for NodeId
  x86/MCE/AMD: Use defines for register addresses in translation code
  x86/MCE/AMD: Use macros to get bitfields in translation code
  x86/MCE/AMD: Drop tmp variable in translation code
  x86/MCE/AMD: Group register reads in translation code
