Subject: KVM: declare ioapic functions only on affected hardware
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b95b51d580bff9376850eef29d34c3aa08c26db7;p=openwrt%2Fstaging%2Fblogic.git

KVM: declare ioapic functions only on affected hardware

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.
