This patch creates interrupt.c. The first user is a callback for hw/* code to trigger an service interrupt for a given sccb value. Several interrupt types for s390 are floating (can be delivered to all CPUs). so this code does not belong to a specific CPU. Other interrupts (like the virtio one) are also floating and can be moved here later on. Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Alexander Graf <agraf@suse.de>
