Subject: [RFC PATCH v2 1/3] irqchip: GICv3: set non-percpu irqs status with IRQ_MOVE_PCNTXT
Date: Mon, 14 Sep 2015 17:29:03 +0800 [thread overview]
Message-ID: <1442222945-10628-2-git-send-email-yangyingliang@huawei.com> (raw)
In-Reply-To: <1442222945-10628-1-git-send-email-yangyingliang@huawei.com>
Use irq_set_status_flags() helper set irqs status with
IRQ_MOVE_PCNTXT. So that it can do set affinity when
calling irq_set_affinity_locked().
