The quilt patch titled
Subject: mm/hugetlb: use online nodes for bootmem allocation
has been removed from the -mm tree. Its filename was

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: use online nodes for bootmem allocation
Date: Fri, 28 Feb 2025 18:29:07 +0000
Later commits will move hugetlb bootmem allocation to earlier in init,
when N_MEMORY has not yet been set on nodes. Use online nodes instead.
At most, this wastes just a few cycles once during boot (and most likely
none).
