Hi all,
This is a revised version of patch 12 from my series to lock down some follow_pfn vs VM_SPECIAL races:
https://lore.kernel.org/dri-devel/CAKwvOdnSrsnTgPEuQJyaOTSkTP2dR9208Y66HQG_h1e2LKfqtw@mail.gmail.com/
Stephen reported an issue on HAVE_PCI_LEGACY platforms which this patch set tries to address. Previous patches are all still in linux-next.
Stephen, would be awesome if you can give this a spin.
Björn/Greg, review on the first patch is needed, I think that's the cleanest approach from all the options I discussed with Greg in this thread:

Cheers, Daniel
