#     Merge tag 'topic/iomem-mmap-vs-gup-2021-02-22' of git://anongit.freedesktop.org/drm/drm
#     
#     Pull follow_pfn() updates from Daniel Vetter:
#      "Fixes around VM_FPNMAP and follow_pfn:
#     
#        - replace mm/frame_vector.c by get_user_pages in misc/habana and
#          drm/exynos drivers, then move that into media as it's sole user
#     
#        - close race in generic_access_phys
#     
#        - s390 pci ioctl fix of this series landed in 5.11 already
#     
#        - properly revoke iomem mappings (/dev/mem, pci files)"
#     
#     * tag 'topic/iomem-mmap-vs-gup-2021-02-22' of git://anongit.freedesktop.org/drm/drm:
#       PCI: Revoke mappings like devmem
#       PCI: Also set up legacy files only after sysfs init
#       sysfs: Support zapping of binary attr mmaps
#       resource: Move devmem revoke code to resource framework
#       /dev/mem: Only set filp->f_mapping
#       PCI: Obey iomem restrictions for procfs mmap
#       mm: Close race in generic_access_phys
#       media: videobuf2: Move frame_vector into media subsystem
#       mm/frame-vector: Use FOLL_LONGTERM
#       misc/habana: Use FOLL_LONGTERM for userptr
#       misc/habana: Stop using frame_vector helpers
#       drm/exynos: Use FOLL_LONGTERM for g2d cmdlists
#       drm/exynos: Stop using frame_vector helpers
