#     powerpc/xive: Export XIVE IPI information for online-only processors.
#     
#     Cédric pointed out that XIVE IPI information exported via sysfs
#     (debug/powerpc/xive) display empty lines for processors which are
#     not online.
#     
#     Switch to using for_each_online_cpu() so that information is
#     displayed for online-only processors.
