+ mm-drop-stale-max_order-references.patch added to mm-new branch

The patch titled
     Subject: mm: drop stale MAX_ORDER references
has been added to the -mm mm-new branch.  Its filename is
     mm-drop-stale-max_order-references.patch

This patch will shortly appear at
     https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-drop-stale-max_order-references.patch

This patch will later appear in the mm-new branch at
    git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Note, mm-new is a provisional staging ground for work-in-progress
patches, and acceptance into mm-new is a notification for others take
notice and to finish up reviews.  Please do not hesitate to respond to
review feedback and post updated versions to replace or incrementally
fixup patches in mm-new.

The mm-new branch of mm.git is not included in linux-next

If a few days of testing in mm-new is successful, the patch will me moved
into mm.git's mm-unstable branch, which is included in linux-next

Before you just go and hit "reply", please:
   a) Consider who else should be cc'ed
   b) Prefer to cc a suitable mailing list as well
   c) Ideally: find the original patch on the mailing list and do a
      reply-to-all to that, adding suitable additional cc's

*** Remember to use Documentation/process/submit-checklist.rst when testing your code ***

The -mm tree is included into linux-next via various
branches at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
and is updated there most days

Subject: mm: drop stale MAX_ORDER references
Date: Wed, 19 Aug 2026 16:20:52 +0800

The treewide rename in commit 5e0a760b4441 ("mm, treewide: rename
MAX_ORDER to MAX_PAGE_ORDER") left a few spots still using the old name:

  - two comments in include/net/mana/mana.h and mm/page_alloc.c;
  - the gdb helper scripts/gdb/linux/mm.py, where self.MAX_ORDER is
    a local mirror of the kernel's MAX_ORDER define.

Rename the leftover instances to MAX_PAGE_ORDER so the tree is consistent.

No functional changes.
