From: "Mike Rapoport (IBM)" <rppt@kernel.org>
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@kernel.org
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.
For tinyconfig and defconfig on x86 I've got
tinyconfig:
text data bss dec hex filename
853206 289376 1200128 2342710 23bf36 a/vmlinux
853198 289344 1200128 2342670 23bf0e b/vmlinux
defconfig:
text data bss dec hex filename
26152959 9730634 2170884 38054477 244aa4d a/vmlinux
26152945 9730602 2170884 38054431 244aa1f b/vmlinux

Something went wrong, I'll resend the whole set.

Sorry, I get lazy on large patches and only ACK instead of checking each
and every line :)
