Subject: [PATCH v3 5/5] MIPS: Select HAVE_IRQ_EXIT_ON_IRQ_STACK
Date: Mon, 19 Dec 2016 14:21:00 +0000	[thread overview]
Message-ID: <1482157260-18730-6-git-send-email-matt.redfearn@imgtec.com> (raw)
In-Reply-To: <1482157260-18730-1-git-send-email-matt.redfearn@imgtec.com>

Since do_IRQ is now invoked on a separate IRQ stack, we select
HAVE_IRQ_EXIT_ON_IRQ_STACK so that softirq's may be invoked directly
from irq_exit(), rather than requiring do_softirq_own_stack.
