Currently, GFP_KERNEL is used as parameter of irq_alloc_descs like below.

          irq_base = irq_alloc_descs(-1, IOH_IRQ_BASE, num_ports[j],
                                     GFP_KERNEL); 

This is not true.
So, this patch uses NUMA_NO_NODE not GFP_KERNEL.

Passing NUMA_NO_NODE means the allocation will be preferred on a node that 
is local to the executing processor.
