  "message": "ARCv3: mm: Better way to setup kernel mappings in per-task page table\n\nIn the current RTP0 only mapping regime, kernel translations are also\nsetup via RTP0 (which canonically is used for user mappings)\n\n - early boot code sets RTP0 directly with kernel swapper_pg_dir / swapper_pud\n\n - when userspace starts, RTP0 has user PGD -\u003e PUD, but kernel identity\n   mapppings are copied into user PUD at right location via\n   arc_map_kernel_in_mm().\n\nSo far this was done on demand:\n - activate_mm()   -\u003e execve\n - arch_dup_mmap() -\u003e fork\n\nHowever a better way to do this is to copy the kernel entries into user pud\nright when user pud is allocated (like some other arches). This avoids the\nneed for the additional arch 2 hooks to do on-demand copy. This patch thus\nremoves them.\n\nSigned-off-by: Vineet Gupta \u003cvgupta@kernel.org\u003e\n",
