  iommu/amd: Remove unused macro (2026-09-11 17:27:22 +0200)

----------------------------------------------------------------
IOMMU fixes for Linux v7.3-rc3:

- RISC-V IOMMU:
  - Serialize command queue publication to prevent concurrent producers
    from exposing incomplete or out-of-order commands to hardware.
  - Wait for queue space outside the command queue lock.
  - Avoid waiting for IOFENCE completion when command enqueue failed.

- AMD IOMMU:
  - Prevent GA log buffers from being reallocated and leaked during
    resume, where allocation also occurs in an unsuitable syscore
    callback context.
  - Fix a regression on older systems whose firmware advertises
    incorrect IOMMU features.
  - Preserve allocation errors when assigning host domain IDs to nested
    domains.

- s390 IOMMU:
  - Prevent a NULL dereference when translating an unmapped IOVA with
    five-level ZPCI translation tables.

- Miscellaneous:
  - Remove a stale MAINTAINERS entry and clean up unused or redundant
    AMD IOMMU declarations, macros, and checks.
