I briefly skimmed over the series, the patch subject prefixes are a bit 
misleading IMHO and could be improved:

> Ankit Agrawal (6):
>    kvm: determine memory type from VMA

this is arch64 specific kvm (kvm/aarch64: ?)

>    vfio/nvgpu: expose GPU device memory as BAR1
>    mm: handle poisoning of pfn without struct pages

mm/memory-failure:

>    mm: Add poison error check in fixup_user_fault() for mapped PFN

That's both MM and core-KVM, maybe worth splitting up.

>    mm: Change ghes code to allow poison of non-struct PFN

That's  drivers/acpi/apei code, not core-mm code.

>    vfio/nvgpu: register device memory for poison handling
