Subject[PATCH 0/2] pci sysfs file iomem revoke support
Hi all,

This is a revised version of patch 12 from my series to lock down some
follow_pfn vs VM_SPECIAL races:

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

Cheers, Daniel

PCI: also set up legacy files only after sysfs init
PCI: Revoke mappings like devmem
