Subject: [PATCH] Fix section type conflict in arch/ia64/xen/xen_pv_ops.c

__initdata and const cannot be always a happy pair, as gcc-4.3.3 gives
the compile errors like:

  arch/ia64/xen/xen_pv_ops.c:156: error: xen_init_ops causes a section type conflict
  arch/ia64/xen/xen_pv_ops.c:340: error: xen_iosapic_ops causes a section type conflict

This patch simply removes const from data with __initdata.
