[PATCH 0/4] ACPI MADT and FADT update according to the ACPI 6.0 spec
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. Ref: https://uefi.org/sites/default/files/resources/ACPI_6_0_Errata_A.PDF This patch series originates from a previous RFC [1] discussion. Reviewed-by tags were kept on patches 2/4 and 3/4.

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 by using the current acceleration name. This would provide values like 'KVM' for example when KVM is used. Ref: https://uefi.org/sites/default/files/resources/ACPI_6_0_Errata_A.PDF Open to discussion, your comments, thoughts and suggestions are very welcome. Thanks in advance.
