Subject: [PATCH v2 02/12] MIPS: BMIPS: Remove use of irq_cpu_offline
Date: Mon, 27 Sep 2021 19:27:05 -0700 [thread overview]
Message-ID: <20210928022715.369160-3-f.fainelli@gmail.com> (raw)
In-Reply-To: <20210928022715.369160-1-f.fainelli@gmail.com>
irq_cpu_offline() is only used by MIPS and we should instead use
irq_migrate_all_off_this_cpu(). This will be helpful in order to remove
drivers/irqchip/irq-bcm7038-l1.c irq_cpu_offline callback which would
have got in the way of making this driver modular.
