[ 22.284175] alloc irq_desc for 55 on node -1
[ 22.284177] alloc kstat_irqs on node -1
What's node "-1" ?
dmesg talks about nodes such things:
[ 0.000000] NR_CPUS:32 nr_cpumask_bits:32 nr_cpu_ids:8 nr_node_ids:1
[ 0.073337] CPU 0/0x0 -> Node 0
there is some "node 0" ... but no idea what -1 is.

that mean for irq_desc related, alloc mem will use mem on
cpu_to_node(cpu) that code is runing
