Huang Shijie 17093c32f6 arm64: irq: set the correct node for VMAP stack ... [ Upstream commit 75b5e0bf90 ] In current code, init_irq_stacks() will call cpu_to_node(). The cpu_to_node() depends on percpu "numa_node" which is initialized in: arch_call_rest_init() --> rest_init() -- kernel_init() --> kernel_init_freeable() --> smp_prepare_cpus() But init_irq_stacks() is called in init_IRQ() which is before arch_call_rest_init(). So in init_irq_stacks(), the cpu_to_node() does not work, it always return 0. In NUMA, it makes the node 1 cpu accesses the IRQ stack which is in the node 0. This patch fixes it by: 1.) export the early_cpu_to_node(), and use it in the init_irq_stacks(). 2.) change init_irq_stacks() to __init function.
