The MADT table structure has been updated in commit 37f33084ed2e ("acpi: arm/virt: madt: use build_append_int_noprefix() API to compose MADT table") to include the 5.2.12.18 GIC ITS Structure and so table's revision also needs to be updated. MADT and the FADT tables from the same spec need to be in sync and in this case also the FADT needs to be updated. Revision 6.0 of the ACPI FADT table introduces the field "Hypervisor Vendor Identity" which is missing and must be included. Patch 2/4 includes a suggestion for the value of this field.
