> x86: Clean up the hypervisor layer
>
> Clean up the hypervisor layer and the hypervisor drivers, using an ops
> structure instead of an enumeration with if statements.
>
> The identity of the hypervisor, if needed, can be tested by testing
> the pointer value in x86_hyper.
>
> The MS-HyperV private state is moved into a normal global variable
> (it's per-system state, not per-CPU state). Being a normal bss
> variable, it will be left at all zero on non-HyperV platforms, and so
> can generally be tested for HyperV-specific features without
> additional qualification.
