2dc458b862 KVM: selftests: Create a vendor independent helper to allocate Hyper-V specific test pages
There's no need to pollute VMX and SVM code with Hyper-V specific
stuff and allocate Hyper-V specific test pages for all test as only
few really need them. Create a dedicated struct and an allocation
helper.

cd8f11bd6b KVM: selftests: Split off load_evmcs() from load_vmcs()
In preparation to putting Hyper-V specific test pages to a dedicated
struct, move eVMCS load logic from load_vmcs(). Tests call load_vmcs()
directly and the only one which needs 'enlightened' version is
evmcs_test so there's not much gain in having this merged.

Temporary pass both GPA and HVA to load_evmcs().

e8f3d23c02 KVM: selftests: Move Hyper-V VP assist page enablement out of evmcs.h
Hyper-V VP assist page is not eVMCS specific, it is also used for
enlightened nSVM. Move the code to vendor neutral place.

d7b14a868a KVM: selftests: Sync 'struct hv_vp_assist_page' definition with hyperv-tlfs.h
'struct hv_vp_assist_page' definition doesn't match TLFS. Also, define
'struct hv_nested_enlightenments_control' and use it instead of opaque
'__u64'.

1ad51c0c0c KVM: selftests: Sync 'struct hv_enlightened_vmcs' definition with hyperv-tlfs.h
'struct hv_enlightened_vmcs' definition in selftests is not '__packed'
and so we rely on the compiler doing the right padding. This is not
obvious so it seems beneficial to use the same definition as in kernel.

761b5ebaa1 KVM: selftests: nVMX: Properly deal with 'hv_clean_fields'
Instead of just resetting 'hv_clean_fields' to 0 on every enlightened
vmresume, do the expected cleaning of the corresponding bit on enlightened
vmwrite. Avoid direct access to 'current_evmcs' from evmcs_test to support
the change.
