[IA64] allocate percpu area in the xen va area.
To guarantee that the percpu is pinned down,
move its virtual address from the xen identity mapped area
to the xen va area which is pinned by DTR[IA64_TR_KERNEL].
Then unnecessary tlb miss fault will be avoided.
Sometimes per cpu area is accessed from very critial
point where tlb miss isn't allowed.
