Subject: [RFC PATCH v5 1/4] genirq: introduce CONFIG_GENERIC_IRQ_MIGRATION
Date: Sat, 19 Sep 2015 11:05:56 +0800 [thread overview]
Message-ID: <1442631959-10228-2-git-send-email-yangyingliang@huawei.com> (raw)
In-Reply-To: <1442631959-10228-1-git-send-email-yangyingliang@huawei.com>
Introduce a more general config for compile kernel/irq/migration.c.
Move the CONFIG_GENERIC_PENDING_IRQ into migration.c. So we can
move other migration interrupts code into migration.c without
select CONFIG_GENERIC_PENDING_IRQ.
