The virt/arm core allocates a kvm_cpu_context_t percpu, at present this is
a typedef to kvm_cpu_context and is used to store host cpu context. The
kvm_cpu_context structure is also used elsewhere to hold vcpu context.
In order to use the percpu to hold additional future host information we
encapsulate kvm_cpu_context in a new structure and rename the typedef and
percpu to match.

We need to fix this function prototype to accept struct kvm_cpu_context,
instead of the now removed kvm_cpu_context_t, to prevent a build break
on arm32 ?
With that :
