Subject[PATCH 4.9 20/31] MIPS: Select HAVE_IRQ_EXIT_ON_IRQ_STACK
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Matt Redfearn <matt.redfearn@imgtec.com>

commit 3cc3434fd6307d06b53b98ce83e76bf9807689b9 upstream.

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.
