    x86/irq: use move_irq_desc() in create_irq_nr() · 15e957d0
    Yinghai Lu authored
    move_irq_desc() will try to move irq_desc to the home node if
    the allocated one is not correct, in create_irq_nr().
    
    ( This can happen on devices that are on different nodes that
      are using MSI, when drivers are loaded and unloaded randomly. )
    
    v2: fix non-smp build
    v3: add NUMA_IRQ_DESC to eliminate #ifdefs
    
    [ Impact: improve irq descriptor locality on NUMA systems ]
