[PATCH 3/3] selftests/x86: Add a missing .note.GNU-stack section to thunks_32.S

From: Andy Lutomirski
Date: Tue Feb 23 2021 - 00:51:22 EST


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").
