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.

Robert Hoo (3):
  x86: Data structure changes to support MSR based features
  kvm: Add support to KVM_GET_MSR_FEATURE_INDEX_LIST and     
    KVM_GET_MSRS system ioctl
  x86: define a new MSR based feature word --
    FEATURE_WORDS_ARCH_CAPABILITIES
