      KVM: ia64: Re-organize data sturure of guests' data area · a917f7af
      Xiantao Zhang 提交于
      1. Increase the size of data area to 64M
      2. Support more vcpus and memory, 128 vcpus and 256G memory are supported
         for guests.
      3. Add the boundary check for memory and vcpu allocation.
      
      With this patch, kvm guest's data area looks as follow:
