[PATCH 0/2] pci sysfs file iomem revoke support

[Daniel Vetter]

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@xxxxxxxxxxxxxx/

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
