Yes. The difference between before the patch and after the patch
is that before we were still going through all the code in tcg_gen_callN,
via the call to gen_helper_rsm macro, only to call finally an empty function 
for CONFIG_USER_ONLY (helper_rsm() {}),

while now we do not generate anything, we do not call the gen_helper_rsm macro 
at all, so we don't go through tcg_gen_callN.

Can we even have an abort() for such cases?
