x86/irq: change MSI irq_desc to be more numa aware
Try to get irq_desc on the home node in create_irq_nr(). v2: don't check if we can move it when sparse_irq is not used v3: use move_irq_des, if that node is not what we want [ Impact: optimization, make MSI IRQ descriptors more NUMA aware ] Signed-off-by: Yinghai Lu <yinghai@kernel.org> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Suresh Siddha <suresh.b.siddha@intel.com> Cc: "Eric W.
