Subject: [PATCH 1/5] riscv: remove cpu_stop()
Date: Mon, 29 Nov 2021 00:07:37 +0800 [thread overview]
Message-ID: <20211128160741.2122-2-jszhang@kernel.org> (raw)
In-Reply-To: <20211128160741.2122-1-jszhang@kernel.org>
Except arch_cpu_idle_dead(), no users of this function. So remove
cpu_stop() and fold its code into arch_cpu_idle_dead().
