KVM: Factor out kvm_vcpu_kick to arch-generic code
The kvm_vcpu_kick function performs roughly the same funcitonality on most all architectures, so we shouldn't have separate copies. PowerPC keeps a pointer to interchanging waitqueues on the vcpu_arch structure and to accomodate this special need a __KVM_HAVE_ARCH_VCPU_GET_WQ define and accompanying function kvm_arch_vcpu_wq have been defined. For all other architectures this is a generic inline that just returns &vcpu->wq; Acked-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Christoffer Dall <c.dall@virtualopensystems.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
