From: "Mike Rapoport (IBM)" <rppt@xxxxxxxxxx> Also in git: https://git.kernel.org/rppt/h/mm-init/v2 v2: * move init_cma_reserved_pageblock() from cma.c to mm_init.c * rename init_mem_debugging_and_hardening() to mem_debugging_and_hardening_init() * inline pgtable_init() into mem_core_init() * add Acked and Reviewed tags (thanks David, hopefully I've picked them right) v1: https://lore.kernel.org/all/20230319220008.2138576-1-rppt@xxxxxxxxxx This set moves most of the core MM initialization to mm/mm_init.c. This largely includes free_area_init() and its helpers, functions used at boot time, mm_init() from init/main.c and some of the functions it calls. Aside from gaining some more space before mm/page_alloc.c hits 10k lines, this makes mm/page_alloc.c to be mostly about buddy allocator and moves the init code out of the way, which IMO improves maintainability. Besides, this allows to move a couple of declarations out of include/linux and make them private to mm/. And as an added bonus there a slight decrease in vmlinux size.
