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.
Based on feedback, this revision also include changes to the MCA init flow.
Patches 1-4: General fixes and cleanups.
Patches 5-10: Add BSP-only init flow and related changes.
Patches 11-15: Updates from v1 set.
Patch 16: Interrupt storm handling rebased on current set.
Thanks, Yazen
--- Changes in v2: - Add general cleanup pre-patches. - Add changes for BSP-only init. - Add interrupt storm handling for AMD. - Link to v1: https://lore.kernel.org/r/20240523155641.2805411-1-yazen.ghannam@amd.com
