From 624d84cfe63b5afdd087bf5b2075a8a8cac5c83f Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Tue, 21 Sep 2010 19:59:44 +0200 Subject: KVM: cpu_relax() during spin waiting for reboot It doesn't really matter, but if we spin, we should spin in a more relaxed manner. This way, if something goes wrong at least it won't contribute to global warming.
