From 5ccd0e43bb916872022df974d0f39337797d9277 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Wed, 5 Mar 2008 12:37:08 +0100 Subject: [S390] idle: Fix machine check handling in idle loop. If a machine check handling is pending when the idle loop is entered default_idle will be left with timer ticks and virtual timer disabled. Fix this by "calling" the idle_chain. Also a BUG_ON(!in_interrupt) in start_hz_timer must be removed since the function now gets called from non interrupt context as well.
