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.

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().

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.
