Subject: [PATCH 13/43] KVM: declare ioapic functions only on affected hardware

From: Christian Borntraeger <borntraeger@...ibm.com>

Since "KVM: Unify the delivery of IOAPIC and MSI interrupts"
I get the following warnings:

  CC [M]  arch/s390/kvm/kvm-s390.o
In file included from arch/s390/kvm/kvm-s390.c:22:
include/linux/kvm_host.h:357: warning: 'struct kvm_ioapic' declared inside parameter list
include/linux/kvm_host.h:357: warning: its scope is only this definition or declaration, which is probably not what you want

This patch limits IOAPIC functions for architectures that have one.
