Add AGDI to the list of known ACPI table signatures to allow the
kernel to recognize it when upgrading tables via initrd.

I'm noticing that this depends on the linux-next-only commit
783dedf41b79ac7a3a68b51cf6f88cbfd6dc3292, so it is probably better if
I apply it and the other patch in the series can be routed via ARM64.

Sounds good to me, thanks. The other patch needs commit dc4e8c07e9e2 
("ACPI: APEI: explicit init of HEST and GHES in apci_init()") in your 
bleeding edge branch to work but it hasn't been acked yet anyway.

Cheers, Ilkka

It is best for both patches to go via Rafael's tree, given the
dependency above. I acked patch (2).

Thanks,
