Thomas Gleixner 5fa4ec9cb2 x86/kvm: Make it compile on 32bit and with HYPYERVISOR_GUEST=n
The reenlightment support for hyperv slapped a direct reference to
x86_hyper_type into the kvm code which results in the following build
failure when CONFIG_HYPERVISOR_GUEST=n:

arch/x86/kvm/x86.c:6259:6: error: ‘x86_hyper_type’ undeclared (first use in this function)
arch/x86/kvm/x86.c:6259:6: note: each undeclared identifier is reported only once for each function it appears in

Use the proper helper function to cure that.

The 32bit compile fails because of:

arch/x86/kvm/x86.c:5936:13: warning: ‘kvm_hyperv_tsc_notifier’ defined but not used [-Wunused-function]

which is a real trainwreck engineering artwork. The callsite is wrapped
into #ifdef CONFIG_X86_64, but the function itself has the #ifdef inside
the function body. Make the function itself wrapped into the ifdef to cure
that.

Qualiteee....
