The quilt patch titled
Subject: fork: use __vmalloc_node() for stack allocation
has been removed from the -mm tree. Its filename was
fork-use-__vmalloc_node-for-stack-allocation.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: fork: use __vmalloc_node() for stack allocation
Date: Mon, 17 Mar 2025 17:36:14 +0100
Replace __vmalloc_node_range() by __vmalloc_node(). The last variant
requires less parameters and it uses exactly the same arguments which are
partly now hidden inside __vmalloc_node().
This change does not change any functionality. It makes the code a bit
simpler.
