Up until now all interrupts on s390 have been floating. For MSI interrupts we've used a global summary bit vector (with a bit for each function) and a per-function interrupt bit vector (with a bit per MSI). This patch introduces a new IRQ delivery mode: CPU directed interrupts. In this new mode a per-CPU interrupt bit vector is used (with a bit per MSI per function). Further it is now possible to direct an IRQ to a specific CPU so we can finally support IRQ affinity. If an interrupt can't be delivered because the appointed CPU is occupied by a hypervisor the interrupt is delivered floating. For this a global summary bit vector is used (with a bit per CPU).
