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

The quilt patch titled
     Subject: resource, kunit: stop selecting GET_FREE_REGION
has been removed from the -mm tree.  Its filename was
     resource-kunit-stop-selecting-get_free_region.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: resource, kunit: stop selecting GET_FREE_REGION
Date: Sat, 26 Sep 2026 02:26:51 +0200

RESOURCE_KUNIT_TEST selects GET_FREE_REGION even when no other option
needs it. Remove the selection to follow the dependency rule in
Documentation/dev-tools/kunit/style.rst.

Skip resource_test_region_intersects() when GET_FREE_REGION is disabled.
GET_FREE_REGION has no prompt, so configurations without a production
consumer cannot enable it. Most configurations will therefore skip this
case; this is intentional. The union and intersection tests remain
available.

Since kunit_skip() does not return, the compiler drops the reference to
the unavailable alloc_free_mem_region(), as in the CONFIG_OF_ADDRESS
check in drivers/of/of_test.c.
