This patch series introduce new ia64 save/restore format
to support pv_ops linux guest.

Currently Linux kernel makes vcpus offline except a boot processor
(vcpu = 0) when saving so that only vcpu = 0 is made online by the tools
stack when restoring. Then Linux kernel itself makes other vcpus up.
On the other hand, pv_ops linux guest doesn't make vcpus offline.
It uses stop_machine_run() keeping all vcpus online.
Thus all of vcpus context must be saved/restored and all vcpus needs to be
made online by the tools stack. So there needs a way to make vcpu online.
Add VGCF_online flag to the XEN_DOMCTL_setvcpucontext hypercall
following the x86 way.

[PATCH 1/3] pv_ops save/restore xen part
            extend hypercall XEN_DOMCTL_setvcpucontext
[PATCH 2/3] pv_ops save/restore restore part
[PATCH 3/3] pv_ops save/restore save part
