Thanks for pointing it out. Yes, it's not used anywhere, it's redundant now. 
But it makes the mapping of ioapic pin and index complete with 'pin'. Maybe we 
can use just list_head of 'ioapicid_pin_intremap_index' to replace the array. I 
will improve the code after Xen 3.4 release, due to it needs many tests on 
multiple platforms.
