[Andrew Morton <akpm@linux-foundation.org>]

The quilt patch titled
     Subject: lib/group_cpus: handle const qualifier from clusters allocation type
has been removed from the -mm tree.  Its filename was
     lib-group_cpus-handle-const-qualifier-from-clusters-allocation-type.patch

This patch was dropped because it was merged into the mm-nonmm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: lib/group_cpus: handle const qualifier from clusters allocation type
Date: Fri, 6 Feb 2026 14:20:13 -0800

In preparation for making the kmalloc family of allocators type aware, we
need to make sure that the returned type from the allocation matches the
type of the variable being assigned.  (Before, the allocator would always
return "void *", which can be implicitly cast to any pointer type.)

The assigned type is "const struct cpumask **", but the returned type,
while matching, is not const qualified.  To get them exactly matching,
just use the dereferenced pointer for the sizeof().
