KVM: selftests: Add wrapper to allocate page table page
Add a helper to allocate a page for use in constructing the guest's page tables. All architectures have identical address and memslot requirements (which appear to be arbitrary anyways). No functional change intended. Signed-off-by: Sean Christopherson <seanjc@google.com> Message-Id: <20210622200529.3650424-15-seanjc@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
