| |
The init_irq_stacks() has been changed to use the correct node: https://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git/commit/?id=75b5e0bf90bf
The init_irq_scs() has the same issue with init_irq_stacks(): cpu_to_node() is not initialized yet, it does not work.
This patch uses early_cpu_to_node() to set the init_irq_scs() with the correct node.
