From 2ffbb3f61e5b2648128f82fe7e506290702a9215 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Wed, 26 May 2010 23:26:21 +0200 Subject: [S390] spp: remove KVM_AWARE_CMF config option This config option enables or disables three single instructions which aren't expensive. This is too fine grained. Besided that everybody who uses kvm would enable it anyway in order to debug performance problems. Just remove it.
