   8 commit 4969d75dd9077e19e175e60f3c5a6c7653252e63 upstream.
   9
  10 In a similar fashion to
  11
  12   b388e57d4628 ("x86/vdso: Fix rethunk patching for vdso-image-{32,64}.o")
  13
  14 annotate vdso-image-x32.o too for objtool so that it gets annotated
  15 properly and the unused return thunk warning doesn't fire.
