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.

At this phase bits in the gate page is same to native.
At the next phase, it will be paravirtualized.

This is a preliminary patch to paravirtualizing fsys.S.
compile fsys.S twice one for native and one for xen, and switch
them at run tine.
Later fsys.S will be paravirtualized.

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.

On ia64/xen, pointer arguments for hypercall is passed
by pseudo physical address(guest physical address.)
So such hypercalls needs address conversion functions.

such hypercalls.

On ia64/xen, pointer argument for the hypercall is passed
by pseudo physical address (guest physical address.)
So it is necessary to convert virtual address into pseudo physical
address right before issuing hypercall. The frame work is called
xencomm. This patch implements arch specific part.
