But we still have

c-r-prctl-add-ability-to-set-new-mm_struct-exe_file-update-after-mm-num_exe_file_vmas-removal.patch
c-r-prctl-add-ability-to-set-new-mm_struct-exe_file-add-minimal-address-test-to-pr_set_mm.patch
c-r-prctl-add-ability-to-get-clear_tid_address.patch
c-r-prctl-drop-vma-flags-test-on-pr_set_mm_-stack-data-assignment.patch

floating about unmerged due to various unresolved issues.  Can we
