Without having the hypercalls available to HVMlite (?) guests these
changes, except possibly those in vmx.c/svm.c, are somewhat pointless
since we never reach patched code.
I understand desire not to increase size of hypercall tables which we
want to eventually get rid of but is it really worth doing (or rather
not doing) at the cost of not including useful functionality?
