LoongArch: Fix early_numa_add_cpu() usage for FDT systems

chenhuacai · chenhuacai · commit 30cec747d6bf · 2024-11-12T16:35:36.000+08:00
early_numa_add_cpu() applies on physical CPU id rather than logical CPU id, so use cpuid instead of cpu. Cc: stable@vger.kernel.org Fixes: 3de9c42 ("LoongArch: Add all CPUs enabled by fdt to NUMA node 0") Reported-by: Bibo Mao <maobibo@loongson.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>
