[IA64] Let Xen handle identity mapping for xenolinux region 7

During kernel build in dom0, half of the resulting slow reflections
are alt DTLB misses. Since we know Linux identity maps region 7,
Xen can handle the miss itself. This reduces the system time component
of the kernel build by nearly 15%.
