From 64e07be544ee9c5fb5b741175262fd34726ec431 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Sat, 16 Apr 2011 02:00:36 +0200 Subject: kvm: ppc: detect old headers When compiling Qemu with older kernel headers, the PVR setting mechanism isn't available yet. Unfortunately, back then I didn't add a capability we could check against, so all we can do is add a configure test to see if we support PVR setting. For BookE, we don't care yet. This fixes compilation errors with KVM enabled on older kernel headers (like 2.6.32).
