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: https://lore.kernel.org/dri-devel/CAKMK7uGrdDrbtj0OyzqQc0CGrQwc2F3tFJU9vLfm2jjufAZ5YQ@xxxxxxxxxxxxxx/ Cheers, Daniel Cc: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx> Cc: Jason Gunthorpe <jgg@xxxxxxxx> Cc: Kees Cook <keescook@xxxxxxxxxxxx> Cc: Dan Williams <dan.j.williams@xxxxxxxxx> Cc: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> Cc: John Hubbard <jhubbard@xxxxxxxxxx> Cc: Jérôme Glisse <jglisse@xxxxxxxxxx> Cc: Jan Kara <jack@xxxxxxx> Cc: Dan Williams <dan.j.williams@xxxxxxxxx> Cc: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> Cc: linux-mm@xxxxxxxxx Cc: linux-arm-kernel@xxxxxxxxxxxxxxxxxxx Cc: linux-samsung-soc@xxxxxxxxxxxxxxx Cc: linux-media@xxxxxxxxxxxxxxx Cc: Bjorn Helgaas <bhelgaas@xxxxxxxxxx> Cc: linux-pci@xxxxxxxxxxxxxxx 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
