To be clearer, the regression is seen with Cset 8972 which firstly uses 
access_ok in common code however ia64 has a different definition. Yes,
 normally ia64 specific changes should go xen-ia64-devel. However 
since I saw the compilation error on xen-unstable, I sent the fix to 
xen-devel to address it directly. 

Sorry for vague description in patch, and let me know if any other issues. 

Thanks,
Kevin
