Subject: [PATCH 0/9] AMD MCA interrupts rework

Hi all,

This set unifies the AMD MCA interrupt handlers with common MCA code.
The goal is to avoid duplicating functionality like reading and clearing
MCA banks.

Patches 1-3 are minor changes for issues found during testing.

Patches 4-9 are revised work of patches 6-12 from the following set:
https://lkml.kernel.org/r/20240404151359.47970-1-yazen.ghannam@amd.com

In addition to addressing review comments, I tried to reduce the amount
of refactoring to only what is functionally needed for fixes and
features. I still want to do a broader clean up, but I think that can
come later.

Patch 7 has a minor merge conflict with the following set:
https://lkml.kernel.org/r/20240521125434.1555845-1-yazen.ghannam@amd.com

The sets do not depend on each other, so I thought to keep them
separate. But I can rebase this one on the other, if needed.

Thanks,
Yazen
