Subject: [PATCH v2 0/2] AMD SMCA Updates

Hi all,

This set adds supports for SMCA changes in future AMD systems.

Patch 1 adds new bank types and error descriptions used in future AMD
systems.

Patch 2 adjusts how SMCA bank information is cached. Future AMD systems
will have different bank type layouts between logical CPUs. So having a
single system-wide cache of the layout won't be correct.

Patch 1 from V1 was dropped from this set. I plan to send another set
for the thresholding sysfs updates discussed here:
https://lkml.kernel.org/r/20211203020017.728440-2-yazen.ghannam@amd.com

I expect there will be a few patches for adding the new interface,
removing the old interface and stale data strucutures, and documenting
the new interface.

Thanks,
Yazen
