Subject: [PATCH 04/12] arch_topology: Reset all cpus in reset_cpu_topology
Date: Wed,  8 Apr 2020 19:34:14 +0800	[thread overview]
Message-ID: <20200408113505.2528103-5-jiaxun.yang@flygoat.com> (raw)
In-Reply-To: <20200408113505.2528103-1-jiaxun.yang@flygoat.com>

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.
