[Andrew Morton]

The quilt patch titled
     Subject: selftests/proc: proc-pid-vm: fix unused variable warning on non-x86
has been removed from the -mm tree.  Its filename was
     selftests-proc-proc-pid-vm-fix-unused-variable-warning-on-non-x86.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: selftests/proc: proc-pid-vm: fix unused variable warning on non-x86
Date: Mon, 12 Oct 2026 07:53:29 -0400

g_vsyscall is only used by the x86_64 test, so clang builds for other
architectures get:

  proc-pid-vm.c:224:21: warning: unused variable 'g_vsyscall' [-Wunused-variable]

The vsyscall strings next to it had the same problem and were marked
__maybe_unused for it. Move all of the vsyscall variables into the
__x86_64__ block that uses them instead, and drop those annotations
along with the local __maybe_unused fallback that was added for them.
