From: Avi Kivity Date: Mon, 29 Dec 2008 15:32:28 +0000 (+0200) Subject: KVM: Fallback support for MSR_VM_HSAVE_PA X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=61a6bd672bda3b9468bf5895c1be085c4e481138;p=linux-beck.git KVM: Fallback support for MSR_VM_HSAVE_PA Since we advertise MSR_VM_HSAVE_PA, userspace will attempt to read it even on Intel. Implement fake support for this MSR to avoid the warnings.
