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.
