KVM: s390: Add implementation-specific trace events
Introduce a new trace system, kvm-s390, for some kvm/s390 specific trace points: - injection of interrupts - delivery of interrupts to the guest - creation/destruction of kvm machines and vcpus - stop actions for vcpus - reset requests for userspace Reviewed-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Avi Kivity <avi@redhat.com>
