Mark Harris 5caae1deee riscv: hwprobe: Avoid uninitialized read in hwprobe_get_cpus() ... When cpusetsize < cpumask_size(), hwprobe_get_cpus() did not fully initialize its copy of the cpu mask, which could cause non-deterministic results from the riscv_hwprobe syscall on a system with more than 8 CPUs when the supplied cpu mask is empty. Address this by fully initializing the cpu mask.
