Something like (works on s390, not tested on x86)?
[PATCH] kvm: use ioapic functions only on affected hardware
From: Christian Borntraeger <borntrae...@de.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.
