[Xen-ia64-devel] [8/9] add mca.c for supporting INIT handler

[Akio Takebe <takebe_akio@xxxxxxxxxxxxxx>]

This is main patch for supporting INIT handler.
I update this patch.
- into xen/arch/ia64/xen
- make smaller mca.c.
  (non-ifdef code)

In ia64_mca_init(), MCA/INIT handler is registered by ia64_sal_set_vectors().
MCA handler is ia64_monarch_init_handler in mca_asm.S
INIT handler is ia64_os_mca_dispatch in mca_asm.S
Now MCA handler is infinity loop. but we'll remake MCA hadler.
Corrected MCA handler is not register now.

INIT handler can show call trace, 
and I think this can be dump entry like kexec/kdump.
