I don't share this fear of function calls, but perhaps that's due to
lack of experience with kdump.

If you want to be extra simple and safe, remove kvm from the equation.
Make the disabling code part of kdump/emergency_restart and only rely on
the convention that cr3.vmxe == vmxon.

That has the advantage of working with other virtualization systems as well.
