This serie is introducing changes to convert runstate address virtual
address provided by a guest during the hypercall on Arm.
It keeps the current strategy on x86 but moves some of the common code
inside the architecture code.
The serie is divided in 2 patches to allow an easier review of the
specific code to handle the use case where the guest area is actually
crossing 2 pages.
