This series had my R-b, but I was waiting for x86 maintainers to ack the
first patch.

But now that I looked at this again, I wonder whether

+#ifdef CONFIG_XEN
ÂBUILD_INTERRUPT3(xen_hvm_callback_vector, HYPERVISOR_CALLBACK_VECTOR,
ÂÂÂÂ ÂÂÂ Âxen_evtchn_do_upcall)
+#endif


and

+#ifdef CONFIG_XEN
Âapicinterrupt3 HYPERVISOR_CALLBACK_VECTOR \
ÂÂÂÂ xen_hvm_callback_vector xen_evtchn_do_upcall
+#endif


should be under XEN_PVHVM
