Isaku Yamahata b46a0b08b8 ia64/xen: fix the link error.
This patch fixes the following link error with xen_domu_defconfig.
Depending on compiler version, it doesn't link as follows.
So remove const and use __initdata for xen_iosapic_ops.

Isaku Yamahata 080104cd0f ia64/pv_ops/xen: elf note based xen startup.
This patch enables elf note based xen startup for IA-64, which gives the
kernel an early hint for running on xen like x86 case.
In order to avoid the multi entry point, presumably extending booting
protocol(i.e. extending struct ia64_boot_param) would be necessary.
It probably means that elilo also needs modification.
