[merged mm-stable] mm-move-__alloc_pages-to-mm-page_alloch.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: mm: move __alloc_pages() to mm/page_alloc.h
has been removed from the -mm tree.  Its filename was
     mm-move-__alloc_pages-to-mm-page_alloch.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: mm: move __alloc_pages() to mm/page_alloc.h
Date: Fri, 03 Jul 2026 12:31:54 +0000

It's no longer used outside of mm/.

Since this means __alloc_pages_noprof() is no longer visible from gfp.h,
this also means moving the definition of alloc_pages_node_noprof into
the .c file.

Also remove references to this API from the documentation tree -
referring to the specific function name was already questionable but
now the function is not even public it definitely seems wrong.

 It is possible to establish how long the stalls were using the function
-tracer to record how long was spent in __alloc_pages() and
+tracer to record how long was spent in the page allocator and
 using the mm_page_alloc tracepoint to identify which allocations were
 for huge pages.
