Yes, but ...

as long as defined(CONFIG_GENERIC_ENTRY) goes away ;)

Thomas, I strongly, strongly disagree with you. But even if you are right
and only CONFIG_GENERIC_ENTRY arches should use TIF_NOTIFY_SIGNAL, why should
this series check CONFIG_GENERIC_ENTRY ?

You can simply nack the patch which adds TIF_NOTIFY_SIGNAL to
arch/xxx/include/asm/thread_info.h.

Oleg.
