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.

add sched_clock() hook to paravirtualize sched_clock().
ia64 sched_clock() is based on ar.itc which isn't stable
on virtualized environment because vcpu may move around on
pcpus. So it needs paravirtualization.

Move down __kernel_syscall_via_epc to the end of the page.
We want to paravirtualize only __kernel_syscall_via_epc because
it includes privileged instructions. Its paravirtualization increases
its symbols size.
On the other hand, each paravirtualized gate must have e symbols of
same value and
paravirtualize gate.S.

Add two hooks, paravirt_get_fsyscall_table() and
paravirt_get_fsys_bubble_doen() to paravirtualize fsyscall implementation.
This patch just add the hooks fsyscall and don't paravirtualize it.

This patch set is intended for the next merge window. They are just
enhancements of the already merged patches or ia64 porting from x86
paravirt techniques and that their quality is enough for merge.
This patch set is for more paravirtualization on ia64/xen domU.
This patch set does
- remove
paravirtualize gate page by allowing each pv_ops instances
to define its own gate page.
