Call irq_set_affinity_hint() to give userspace programs such as irqbalance the information to be able to distribute qib interrupts appropriately. The logic allocates all non-receive interrupts to the first CPU local to the HCA. Receive interrupts are allocated round robin starting with the second CPU local to the HCA with potential wrap back to the second CPU. This patch also adds a refinement to the name registered for MSI-X interrupts so that user level scripts can determine the device associated with the IRQs when there are multiple HCAs with a potentially different set of local CPUs.
