Subject: [PATCH v2 0/2] KVM: x86: don't announce KVM_CAP_HYPERV_ENLIGHTENED_VMCS when it is unavailable

It was discovered that hyperv_cpuid test now fails on AMD as it tries to
enable KVM_CAP_HYPERV_ENLIGHTENED_VMCS which is (wrongfully) reported as
available.

Changes since v1:
- This is a v2 for '[PATCH 0/3] KVM: x86: fix a couple of issues with
 Enlightened VMCS enablement' renamed as the first patch of the series
 was already merged.
- Added Jim's Reviewed-by: to PATCH1
- Added missing break in PATCH2 [Jim Mattson, Sean Christopherson] 

Vitaly Kuznetsov (2):
  KVM: x86: svm: remove unneeded nested_enable_evmcs() hook
  KVM: x86: announce KVM_CAP_HYPERV_ENLIGHTENED_VMCS support only when
    it is available
