From: Zeng Tao <prime.zeng@xxxxxxxxxxxxx> If the /cpus node contains nodes other than /cpus/cpu*, for example: /cpus/cpu-map/. The test will issue an unexpected assert error as follow: [root@localhost]# ./arm-run arm/spinlock-test.flat qemu-system-aarch64 -nodefaults -machine virt,gic-version=host,accel=kvm -cpu host -device virtio-serial-device -device virtconsole,chardev=ctd -chardev testdev,id=ctd -device pci-testdev -display none -serial stdio -kernel arm/spinlock-test.flat # -initrd /tmp/tmp.mwPLiF4EWm lib/arm/setup.c:64: assert failed: ret == 0 STACK: In this patch, ignore the non-cpu subnodes instead of return an error.
