Thread-topic: [Xen-ia64-devel][PATCH] Implement IOSAPIC handler for IPF side
Create viosapic handling for IPF.
There are three reasons to do this.
1. IOSAPIC is different with IOAPIC 
   such as:
       1. IOAPIC implement broadcast, but IOSAPIC doesn't
       2. IOSAPIC doesn't implement dest_mode and remote irr bits.
       3. IOSAPIC implement EOI but IOAPIC doesn't
       etc.
2. In IA32 side there are I8259 and LAPIC who are
    related to IOAPIC, but In IPF there is no I8259 and has LSAPIC.
3. after creating this file, all header files under asm-ia64/hvm, which
   are linked from IA32 side, are not needed.
