[Andrew Morton]

The patch titled
     Subject: sh: remove setup_bootmem_node() and plat_mem_setup()
has been added to the -mm mm-new branch.  Its filename is
     sh-remove-setup_bootmem_node-and-plat_mem_setup.patch

This patch will shortly appear at
     https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/sh-remove-setup_bootmem_node-and-plat_mem_setup.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: sh: remove setup_bootmem_node() and plat_mem_setup()
Date: Sun, 10 May 2026 16:55:40 +0300

setup_bootmem_node() and plat_mem_setup() were needed to setup NUMA
"nodes" for URAM memory ranges.  Since there is no NUMA support anymore,
these functions are not needed.

Remove them.
