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_h1e2lkf...@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: https://lore.kernel.org/dri-devel/cakmk7ugrddrbtj0oyzqqc0cgrqwc2f3tfju9vlfm2jjufaz...@mail.gmail.com/ Cheers, Daniel Cc: Stephen Rothwell <s...@canb.auug.org.au> Cc: Jason Gunthorpe <j...@ziepe.ca> Cc: Kees Cook <keesc...@chromium.org> Cc: Dan Williams <dan.j.willi...@intel.com> Cc: Andrew Morton <a...@linux-foundation.org> Cc: John Hubbard <jhubb...@nvidia.com> Cc: Jérôme Glisse <jgli...@redhat.com> Cc: Jan Kara <j...@suse.cz> Cc: Dan Williams <dan.j.willi...@intel.com> Cc: Greg Kroah-Hartman <gre...@linuxfoundation.org> Cc: linux...@kvack.org Cc: linux-arm-ker...@lists.infradead.org Cc: linux-samsung-...@vger.kernel.org Cc: linux-me...@vger.kernel.org Cc: Bjorn Helgaas <bhelg...@google.com> Cc: linux-...@vger.kernel.org Daniel Vetter (2): PCI: also set up legacy files only after sysfs init PCI: Revoke mappings like devmem drivers/pci/pci-sysfs.c | 11 +++++++++++ drivers/pci/proc.c | 1 + 2 files changed, 12 insertions(+) -- 2.30.0
