Yeah, that patch is not actually converting the pfn_valid() users to only trust VM_IO, it only does a few special cases (notably the follow_pages() thing, which wasn't the issue here). So the patch would have to be expanded to cover _all_ of the page table following functions. It probably isn't that much, just looking for code that checks for PageReserved() will pinpoint the needed users pretty well. So I think the VM_IO approach could fix this, but it would need to be fleshed out more. In the meantime, fixing pfn_valid() is definitely the right thing to do.
