OK, I applied the 2 patches on top of next-20210205 and it no longer panics for my simple boot test (PowerPC pseries_le_defconfig under qemu). -- Cheers, Stephen Rothwell pgpf3iU_oYjSC.pgp Description: OpenPGP digital signature
[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: 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 Cc: Jason Gunthorpe Cc: Kees Cook Cc: Dan Williams Cc: Andrew Morton Cc: John Hubbard Cc: Jérôme Glisse Cc: Jan Kara Cc: Dan Williams Cc: Greg Kroah-Hartman 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 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
