Subject[PATCH v4 0/5] Refactor handling flow of KVM_SET_CPUID*
4 Patches of v3 has been queued into kvm/queue branch. This v4 contains
the rest to refactor the flow of KVM_SET_CPUID* as:

1. cpuid check: check if userspace provides legal CPUID settings;

2. cpuid update: Update userspace provided CPUID settings. It currently
only contains kvm_update_cpuid_runtime, which updates special CPUID
bits based on the vcpu state, e.g., OSXSAVE, OSPKE. In the future, we
can re-introduce kvm_update_cpuid() if KVM needs to force on/off some

3. update vcpu states: Update vcpu states/settings based on the final updated
CPUID settings.

- remove 4 queued patches
- rebased to kvm/queue: c16ced9cc67a "x86/kvm/vmx: Use native read/write_cr2()"
- fix one bug in v3 to call kvfree(cpuid_entries) in kvm_vcpu_ioctl_set_cpuid()
- rename "update_vcpu_model" to "vcpu_after_set_cpuid" [Paolo]
- Add a new patch to extrace kvm_update_cpuid_runtime()

- Add a note in KVM api doc to state the previous CPUID configuration
is not reliable if current KVM_SET_CPUID* fails [Jim]
- Adjust Patch 2 to reduce code churn [Sean]
- Commit message refine to add more justification [Sean]
- Add a new patch 7

- rebase to kvm/queue: a037ff353ba6 ("Merge branch 'kvm-master' into HEAD")
- change the name of kvm_update_state_based_on_cpuid() to
kvm_update_vcpu_model() [Sean]
- Add patch 5 to rename kvm_x86_ops.cpuid_date() to
