Please don't introduce anymore of these insane ad-hoc crazy architecture macros.
Just make it a regular config option, which makes it much easier for architectures to just select it at config time.
So make it something like CONFIG_IRQ_EXIT_ON_IRQ_STACK, and then x86-64 (and now Power) can just do
select IRQ_EXIT_ON_IRQ_STACK
in their arch/*/Kconfig files.
Basically, we really should strive to get rid of all those insane [__]ARCH_xyzzy flags. We have too many of them, and they are insane.
