    x86, sparseirq: move irq_desc according to smp_affinity, v7 · 48a1b10a
    Yinghai Lu authored
    Impact: improve NUMA handling by migrating irq_desc on smp_affinity changes
    
    if CONFIG_NUMA_MIGRATE_IRQ_DESC is set:
    
    -  make irq_desc to go with affinity aka irq_desc moving etc
    -  call move_irq_desc in irq_complete_move()
    -  legacy irq_desc is not moved, because they are allocated via static array
    
    for logical apic mode, need to add move_desc_in_progress_in_same_domain,
    otherwise it will not be moved ==> also could need two phases to get
    irq_desc moved.
