[merged mm-stable] mm-hugetlb-move-huge_boot_pages-list-init-to-hugetlb_bootmem_alloc.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: mm/hugetlb: move huge_boot_pages list init to hugetlb_bootmem_alloc
has been removed from the -mm tree.  Its filename was
     mm-hugetlb-move-huge_boot_pages-list-init-to-hugetlb_bootmem_alloc.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/hugetlb: move huge_boot_pages list init to hugetlb_bootmem_alloc
Date: Fri, 28 Feb 2025 18:29:17 +0000

Instead of initializing the per-node hugetlb bootmem pages list from the
alloc function, we can now do it in a somewhat cleaner way, since there is
an explicit hugetlb_bootmem_alloc function.  Initialize the lists there.
