Subject: [PATCH 0/3] KVM: x86: fix a couple of issues with Enlightened VMCS enablement

It was discovered that:
- hyperv_cpuid test fails on AMD
- hyperv_cpuid test crashes kernel on Intel when nested=0
The test itself is good, we need to fix the issues.

Vitaly Kuznetsov (3):
  KVM: x86: hyper-v: don't crash on KVM_GET_SUPPORTED_HV_CPUID when
    kvm_intel.nested is disabled
  KVM: x86: svm: remove unneeded nested_enable_evmcs() hook
  KVM: x86: announce KVM_CAP_HYPERV_ENLIGHTENED_VMCS support only when
    it is available
