From fafc0b6afed9d913ddbcd2da87e5d39da9bf04c5 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Wed, 25 May 2011 15:04:42 +0200 Subject: PPC: fix sregs usage on booke When compiling qemu with kvm support on BookE PPC machines, I get the following error: cc1: warnings being treated as errors /tmp/qemu/target-ppc/kvm.c: In function 'kvm_arch_get_registers': /tmp/qemu/target-ppc/kvm.c:188: error: unused variable 'sregs' This is due to overly ambitious #ifdef'ery introduced in 90dc88. Fix it by keeping code that doesn't depend on new headers alive for the compiler, but never executed due to failing capability checks.
