KVM: s390: adapter interrupt sources
Add a new interface to register/deregister sources of adapter interrupts identified by an unique id via the flic. Adapters may also be maskable and carry a list of pinned pages. These adapters will be used by irq routing later. Acked-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com>
