Subject: [PATCH for-4.9 5/7] MIPS: Select HAVE_IRQ_EXIT_ON_IRQ_STACK

From: Matt Redfearn <matt.redfearn@...tec.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.
