This is needed so that the staging hyperv can properly access this
symbol.

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.

This should have been GPLv2 only, we cut and pasted from the wrong file
originally, sorry.
Also removed some unneeded boilerplate license code, we all know where
to find the GPLv2, and that there's no warranty as that is implicit from
the license.
