Subject: [PATCH v2 3/3] selftests/x86: Add a missing .note.GNU-stack section to thunks_32.S
Date: Tue, 23 Feb 2021 10:15:10 -0800	[thread overview]
Message-ID: <4a79388a8ec4fc4c07e61d79ad4fca5c106bba80.1614104065.git.luto@kernel.org> (raw)
In-Reply-To: <cover.1614104065.git.luto@kernel.org>

test_syscall_vdso_32 ended up with an executable stacks because the asm was
missing the annotation that says that it is modern and doesn't need an
executable stack.  Add the annotation.

This was missed in commit aeaaf005da1d ("selftests/x86: Add missing
.note.GNU-stack sections").
