Huacai Chen 28e112afa4 LoongArch: cpuinfo: Fix a warning for CONFIG_CPUMASK_OFFSTACK ... When CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS is selected, cpu_max_bits_warn() generates a runtime warning similar as below while we show /proc/cpuinfo. Fix this by using nr_cpu_ids (the runtime limit) instead of NR_CPUS to iterate CPUs.
