+; Same Ring 0 / CPL 0 entry context as the exception stubs above: the CPU
+; entered with IF cleared (interrupt gate), no privilege change, so only
+; RIP/CS/RFLAGS were pushed. IRQs never carry a CPU error code, so every
+; stub normalizes with a dummy 0 exactly like ISR_NOERR, keeping the
+; [vector, error] layout — and thus struct interrupt_frame — identical to
+; the exception path. Field order must stay in sync with include/idt.h.
+; The EOI is sent by the C dispatcher (pic_eoi), not here, so a future
+; per-IRQ EOI policy only touches C. -mno-red-zone keeps pushes safe.
