Memory-only nodes should have been updated in\nof_numa_parse_memory_nodes, but they weren't.\n\nSubsequently, when free_area_init() attempts to access NODE_DATA() for\nthese uninitialized memory nodes, the kernel panics due to NULL pointer\ndereference.\n\nThis can be reproduced on ARM64 QEMU with 1 CPU and 2 memory nodes:\n\nqemu-system-aarch64 \\\n-cpu host -nographic \\\n-m 4G -smp 1
