I believe that this is fixed in this updated version:
b8eb8a06afe1 ("EXP arch/x86: Test one-byte cmpxchg emulation")
But please let me know if I am missing something here.

OK, what I am missing is my failure to have changed ARCH_NEED_CMPXCHG_1_2_EMU
to ARCH_NEED_CMPXCHG_1_EMU. On it! And yet again, thank you for your testing
