I guess you'll need to make nmi_callback() return values tristate and adjust do_nmi() to deal with both cases. Albeit - the other two users are breaking this too, so perhaps do_nmi() should be adjusted in a prereq (and backportable) patch to not bail in that case. Yet a tristate may still be needed, since alternative_instructions() legitimately wants to suppress them getting handled - it would just need to invoke their handling once done with patching.
