So we have the following patches in this series: 1. arm64: untag user pointers in access_ok and __uaccess_mask_ptr 2. arm64: Introduce prctl() options to control the tagged user addresses ABI 3. lib: untag user pointers in strn*_user 4. mm: untag user pointers passed to memory syscalls 5. mm: untag user pointers in mm/gup.c 6. mm: untag user pointers in get_vaddr_frames 7. fs/namespace: untag user pointers in copy_mount_options 8. userfaultfd: untag user pointers 9. drm/amdgpu: untag user pointers 10. drm/radeon: untag user pointers in radeon_gem_userptr_ioctl 11. IB/mlx4: untag user pointers in mlx4_get_umem_mr 12. media/v4l2-core: untag user pointers in videobuf_dma_contig_user_get 13. tee/shm: untag user pointers in tee_shm_register 14. vfio/type1: untag user pointers in vaddr_get_pfn 15. selftests, arm64: add a selftest for passing tagged pointers to kernel 1, 2 and 15 have been picked by Will. 11 has been picked up by Jason. 9, 10, 12, 13 and 14 have acks from their subsystem maintainers. 3 touches generic lib code, I'm not sure if there's a dedicated maintainer for that. The ones that are left are the mm ones: 4, 5, 6, 7 and 8. Andrew, could you take a look and give your Acked-by or pick them up directly? > > Make sense? > > Cheers, > > Will Thanks!
