of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: mm: move some stuff to mm/page_alloc.h
Date: Fri, 03 Jul 2026 12:31:47 +0000

Some of this stuff in the public header is only used internally so shrink
the scope to avoid silently growing new users.

drain_local_pages() is still used from kernel/power/snapshot.c so that
needs to stay behind.
