Subject: [RFC PATCH v1 2/4] irqchip: GICv3: set non-percpu irqs status with _IRQ_MOVE_PCNTXT
Date: Sun, 6 Sep 2015 12:23:39 +0800 [thread overview]
Message-ID: <1441513421-8092-3-git-send-email-yangyingliang@huawei.com> (raw)
In-Reply-To: <1441513421-8092-1-git-send-email-yangyingliang@huawei.com>
Use irq_settings_set_move_pcntxt() helper irqs status with
_IRQ_MOVE_PCNTXT. So that it can do set affinity when calling
irq_set_affinity_locked().
