Impact: cleanup init_one_irq_desc() does not initialize the desc->lock properly - you cannot init a lock by memcpying some other lock on it. This happens to work right now (because irq_desc_init is never in use), but it's a dangerous construct nevertheless, so fix it. Signed-off-by: NIngo Molnar <mingo@elte.hu>

Impact: reduce printk noise There were a couple of leftover KERN_DEBUG debugging printks, remove them. Also clarify an error message. Signed-off-by: NIngo Molnar <mingo@elte.hu>

Impact: reduce kconfig variable scope and clean up Bartlomiej pointed out that the config dependencies and comments are not right. update it depend to NUMA, and fix some comments Reported-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com> Signed-off-by: NYinghai Lu <yinghai@kernel.org> Signed-off-by: NIngo Molnar <mingo@elte.hu>

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.
