The quilt patch titled
Subject: selftests/vm: ksm_functional_tests: fixes for 32bit
has been removed from the -mm tree. Its filename was
selftests-vm-ksm_functional_tests-fixes-for-32bit.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: selftests/vm: ksm_functional_tests: fixes for 32bit
Date: Mon, 5 Dec 2022 20:37:16 +0100
The test currently fails on 32bit. Fixing the "-1ull" vs. "-1ul" seems
to make the test pass and the compiler happy.
Note: This test is not in mm-stable yet. This fix should be squashed into
"selftests/vm: add KSM unmerge tests".
