6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Huang Shijie <shijie@xxxxxxxxxxxxxxxxxxxxxx> commit 7b1a09e44dc64f4f5930659b6d14a27183c00705 upstream. 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.
