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.
