I'm not sure I see a way to cater for Andrew requests while allowing
PV_SHIM_EXCLUSIVE to gate options in order to be able to remove
code.

Maybe PV_SHIM_EXCLUSIVE should be moved to the top level Kconfig
screen on x86 and behave like a list, so that you select a 'Normal'
hypervisor build or a 'PV shim exclusive' build, and that could
completely change the contents of the menus?

If that doesn't seem suitable I think the proposed patch is a good
option unless someone has a better approach.

Thanks, Roger.
