riscv: cpu-hotplug: clear cpu from numa map when teardown
There is numa_add_cpu() when cpus online, accordingly, there should be numa_remove_cpu() when cpus offline. Signed-off-by: Pingfan Liu <kernelfans@gmail.com> Fixes: 4f0e8eef772e ("riscv: Add numa support for riscv64 platform") Cc: stable@vger.kernel.org [Palmer: Add missing NUMA include] Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
