Subject: [RFC PATCH v4 1/4] genirq: introduce CONFIG_GENERIC_IRQ_MIGRATION
Date: Thu, 17 Sep 2015 13:19:23 +0800 [thread overview]
Message-ID: <1442467166-1460-2-git-send-email-yangyingliang@huawei.com> (raw)
In-Reply-To: <1442467166-1460-1-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.
