Niklas Schnelle a8b5611ffe s390/pci: do not set affinity for floating irqs ... commit 86dbf32da1 upstream. with the introduction of CPU directed interrupts the kernel parameter pci=force_floating was introduced to fall back to the previous behavior using floating irqs. However we were still setting the affinity in that case, both in __irq_alloc_descs() and via the irq_set_affinity callback in struct irq_chip. For the former only set the affinity in the directed case. The latter is explicitly set in zpci_directed_irq_init() so we can just leave it unset for the floating case.
