Adrian Huang 0bbe4ced53 iommu/amd: Fix the overwritten field in IVMD header ... Commit 387caf0b75 ("iommu/amd: Treat per-device exclusion ranges as r/w unity-mapped regions") accidentally overwrites the 'flags' field in IVMD (struct ivmd_header) when the I/O virtualization memory definition is associated with the exclusion range entry. This leads to the corrupted IVMD table (incorrect checksum). The kdump kernel reports the invalid checksum: ACPI BIOS Warning (bug): Incorrect checksum in table [IVRS] - 0x5C, should be 0x60 (20200717/tbprint-177) AMD-Vi: [Firmware Bug]: IVRS invalid checksum Fix the above-mentioned issue by modifying the 'struct unity_map_entry' member instead of the IVMD header. Cleanup: The *exclusion_range* functions are not used anymore, so get rid of them.
