Yes. This change makes sense given that for_each_online_cpu expands into the same.

Why not do for the remaining ones too?

linux_tip$ grep -Rw "for_each_cpu" * | grep  cpu_online_mask
arch/riscv/kernel/unaligned_access_speed.c:     for_each_cpu(cpu, cpu_online_mask) {

Rest everyone seems to have moved.
