Vitaly Kuznetsov 3a2f5773ba x86/kvm/hyper-v: nested_enable_evmcs() sets vmcs_version incorrectly 
Commit e2e871ab2f ("x86/kvm/hyper-v: Introduce nested_get_evmcs_version()
helper") broke EVMCS enablement: to set vmcs_version we now call
nested_get_evmcs_version() but this function checks
enlightened_vmcs_enabled flag which is not yet set so we end up returning
zero.

Fix the issue by re-arranging things in nested_enable_evmcs().

Vitaly Kuznetsov e2e871ab2f x86/kvm/hyper-v: Introduce nested_get_evmcs_version() helper 
The upcoming KVM_GET_SUPPORTED_HV_CPUID ioctl will need to return
Enlightened VMCS version in HYPERV_CPUID_NESTED_FEATURES.EAX when
it was enabled.

Sean Christopherson 75edce8a45 KVM: VMX: Move eVMCS code to dedicated files 
The header, evmcs.h, already exists and contains a fair amount of code,
but there are a few pieces in vmx.c that can be moved verbatim.  In
addition, move an array definition to evmcs.c to prepare for multiple
consumers of evmcs.h.
