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.

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