From 8d6f7c5aa3db6f3e5e43d09f8a0166c7d96f33f3 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Fri, 23 May 2014 18:15:26 +1000 Subject: powerpc/powernv: Make it possible to skip the IRQHAPPENED check in power7_nap() To support split core we need to be able to force all secondaries into nap, so the core can detect they are idle and do an unsplit. Currently power7_nap() will return without napping if there is an irq pending. We want to ignore the pending irq and nap anyway, we will deal with the interrupt later.
