KVM: ia64: Implement a uniform vps interface
An uniform entry kvm_vps_entry is added for vps_sync_write/read, vps_resume_handler/guest, and branches to differnt PAL service according to the offset. Singed-off-by: Anthony Xu <anthony.xu@intel.com> Signed-off-by: Xiantao Zhang <xiantao.zhang@intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>
