KVM: s390: infrastructure to kick vcpus out of guest state
To ensure vcpu's come out of guest context in certain cases this patch adds a s390 specific way to kick them out of guest context. Currently it kicks them out to rerun the vcpu_run path in the s390 code, but the mechanism itself is expandable and with a new flag we could also add e.g. kicks to userspace etc. Signed-off-by: Christian Ehrhardt <ehrhardt@linux.vnet.ibm.com> Signed-off-by: Avi Kivity <avi@redhat.com>
