Hi. This patchset implements xen/ia64 domU support.
Qing He and Eddie Dong also has been woring on pv_ops so that
I want to discuss before going further and avoid duplicated work.
I suppose that Eddie will also post his own patch. So reviewing both
patches, we can reach to better pv_ops interface.

make ipi_to_irq globly visible. ia64/xen nees to reference it from other file.
introduce resend_irq_on_evtchn() which ia64 needs.
introduce xen_do_IRQ() to split out arch specific code.

Those definitions in include/asm/xen/page.h are arch specific.
ia64/xen wants to define its own version. So move them to arch specific
directory and keep include/xen/page.h in order not to break compilation.

Don't use alloc_vm_area()/free_vm_area() directly, instead define
xen_alloc_vm_area()/xen_free_vm_area() and use them.
alloc_vm_area()/free_vm_area() are used to allocate/free area which
are for grant table mapping. Xen/x86 grant table is based on virtual
address so that
__local_irq_save() and local_save_flags() are used to mask interruptions.
They read all psr bits that requres whole bit emulation.
On the other hand, reading only psr.i, the single bit, can be virtualized
cheaply.

On xen/ia64 and xen/powerpc hypercall arguments are passed by pseudo
physical address (guest physical address) so that it's necessary to
convert from virtual address into pseudo physical address. The frame
work is called xencomm.
Import arch generic part of xencomm.

To make them overridable cleanly, change their prefix from ia64_ to native_
and define ia64_ to native_.
Later ia64_xxx would be redeinfed to pv_ops'ed one.

Make ia64 privileged instruction intrinsics paravirtualizable with binary

Currently it detects by checking psr.cpl != 0.
It's ok for now, but more abstraction would be needed later like x86.
Presumably extending booting protocol (i.e. extending struct ia64_boot_param)
or multi entry points depending on hypervisor would be necessary.

This isn't necessary because xen defines its own DO_SAVE_MIN.

With binary patching, make intrinsics paravirtualization hypervisor neutral.
So far xen intrinsics doesn't allow another hypervisor.
Binary patch marked privileged operations which needs paravirtualization
if running on xen at early boot time.
