From: Sachin Sant <sach...@linux.ibm.com> [ Upstream commit 279d1a72c0f8021520f68ddb0a1346ff9ba1ea8c ]
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.
