* KVM/ARM VGIC state saving and restoring implementation.<br>  Completed the initial RFC patch and sent it out.<br>  [RFC PATCH 1/1] KVM: ARM: add vgic state save and restore support<br>  During the implementation, I met a lot issues and some of them were hard to make decision.<br>
  There&#39;re two different ways to implement such function, however, each way has different issues.<br>  I currently can not make sure which one is better. So i raised them in the RFC patch and request<br>  for people&#39;s comments and suggestions.<br>
