init,mm: fold late call to page_ext_init() to page_alloc_init_late()

When deferred initialization of struct pages is enabled, page_ext_init()
must be called after all the deferred initialization is done, but there is
no point to keep it a separate call from kernel_init_freeable() right
after page_alloc_init_late().

Fold the call to page_ext_init() into page_alloc_init_late() and localize
deferred_struct_pages variable.

The bulk of memory management initialization code is spread all over

difficult.

Move most of the functions marked __init and __meminit to mm/mm_init.c to
make it better localized and allow some more spare room before
mm/page_alloc.c reaches 10k lines.

No functional changes.

Pull MM updates from Andrew Morton:

- More userfaultfs work from Peter Xu

- Several convert-to-folios series from Sidhartha Kumar and Huang Ying

- Some filemap cleanups from Vishal Moola

- David Hildenbrand added the ability to selftest anon memory COW
handling

- Some cpuset simplifications from Liu Shixin

- Addition of vmalloc tracing support by Uladzislau Rezki

- Some pagecache folioifications and simplifications from Matthew
Wilcox

- A pagemap cleanup from Kefeng Wang: we have VM_ACCESS_FLAGS, so use
it

- Miguel Ojeda contributed some cleanups for our use of the
__no_sanitize_thread__ gcc keyword.

This series should have been in the non-MM tree, my bad

- Naoya Horiguchi improved the interaction between memory poisoning and
memory section removal for huge pages

- DAMON cleanups and tuneups from SeongJae Park

- Tony Luck fixed the handling of COW faults against poisoned pages

- Peter Xu utilized the PTE marker code for handling swapin errors

- Hugh Dickins reworked compound page mapcount handling, simplifying it
and making it more efficient

- Removal of the autonuma savedwrite infrastructure from Nadav Amit and
David Hildenbrand

- zram support for multiple compression streams from Sergey Senozhatsky

- David Hildenbrand reworked the GUP code's R/O long-term pinning so
that drivers no longer need to use the FOLL_FORCE workaround which
didn't work very well anyway

- Mel Gorman altered the page allocator so that local IRQs can remnain
enabled during per-cpu page allocations

- Vishal Moola removed the try_to_release_page() wrapper

- Stefan Roesch added some per-BDI sysfs tunables which are used to
prevent network block devices from dirtying excessive amounts of
pagecache

- David Hildenbrand did some cleanup and repair work on KSM COW
breaking

- Nhat Pham and Johannes Weiner have implemented writeback in zswap's
zsmalloc backend

- Brian Foster has fixed a longstanding corner-case oddity in
file[map]_write_and_wait_range()

- sparse-vmemmap changes for MIPS, LoongArch and NIOS2 from Feiyang
Chen

- Shiyang Ruan has done some work on fsdax, to make its reflink mode
work better under xfstests. Better, but still not perfect

- Christoph Hellwig has removed the .writepage() method from several
filesystems. They only need .writepages()

- Yosry Ahmed wrote a series which fixes the memcg reclaim target
beancounting

- David Hildenbrand has fixed some of our MM selftests for 32-bit
machines
