Subject: [PATCH 1/3] riscv: Allow forced irq threading
Date: Thu, 8 Jul 2021 09:59:47 +0800	[thread overview]
Message-ID: <20210708015949.20076-2-wangkefeng.wang@huawei.com> (raw)
In-Reply-To: <20210708015949.20076-1-wangkefeng.wang@huawei.com>

The timer interrupt and the perf interrupt on riscv are with
IRQF_PERCPU, so it's safe to allow forced interrupt threading.
