KVM side has added the framework (kvm.git:d1d93fa90) to support MSR based features. Here is the QEMU part, including data structure changes/expanding, referring functions changes, and the implementations on KVM_GET_MSR_FEATURE_INDEX_LIST and KVM_GET_MSRS system ioctl. Changelog: v4: Re-organize patch set to conform to request of individually build pass. Add KVM capability check for KVM_GET_MSR_INDEX_LIST before fetch. Special treatment for MSR_IA32_ARCH_CAPABILITIES.RSBA. Use more convenient glib wrapper (g_strdup_printf) instead of native (sprintf). v3: patch 2&3 in v2 are corrupted. Re-format patches. v2: coding style changes to pass ./scripts/checkpatch.pl.
