From: Yazen Ghannam <yazen.ghannam@amd.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
