[PATCH v2 04/11] arch_topology: Reset all cpus in reset_cpu_topology
From: Jiaxun Yang
Date: Sat Apr 11 2020 - 23:26:16 EST
For MIPS platform, when topology isn't probed by DeviceTree,
possible_cpu might be empty when calling init_cpu_topology,
that may result cpu_topology not fully reseted for all CPUs.
So here we can reset all cpus instead of possible cpus.

v2: Use ARRAY_SIZE instead of NR_CPUS.
