KVM: PPC: Book3S: Facilities to save/restore XICS presentation ctrler state
This adds the ability for userspace to save and restore the state of the XICS interrupt presentation controllers (ICPs) via the KVM_GET/SET_ONE_REG interface. Since there is one ICP per vcpu, we simply define a new 64-bit register in the ONE_REG space for the ICP state. The state includes the CPU priority setting, the pending IPI priority, and the priority and source number of any pending external interrupt.
