[merged mm-stable] sh-mm-drop-allocate_pgdat.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: sh: mm: drop allocate_pgdat()
has been removed from the -mm tree.  Its filename was
     sh-mm-drop-allocate_pgdat.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: sh: mm: drop allocate_pgdat()
Date: Sun, 10 May 2026 16:55:39 +0300

allocate_pgdat() function used to allocate the node data structure and
initialize its node_start_pfn and node_spanned_pages fields.

Without CONFIG_NUMA there is no need to allocate the node data and setting
node_start_pfn and node_spanned_pages are redundant because they are
anyway overwritten later by core MM.

Remove allocate_pgdat() function.
