  "message": "keep rd-\u003eonline and cpu_online_map in sync\n\nIt is possible to allow the root-domain cache of online cpus to\nbecome out of sync with the global cpu_online_map.  This is because we\ncurrently trigger removal of cpus too early in the notifier chain.\nOther DOWN_PREPARE handlers may in fact run and reconfigure the\nroot-domain topology, thereby stomping on our own offline handling.\n\nThe end result is that rd-\u003eonline may become out of sync with\ncpu_online_map, which results in potential task misrouting.\n\nSo change the offline handling to be more tightly coupled with the\nglobal offline process by triggering on CPU_DYING intead of\nCPU_DOWN_PREPARE.\n\nSigned-off-by: Gregory Haskins \u003cghaskins@novell.com\u003e\nCc: Gautham R Shenoy \u003cego@in.ibm.com\u003e\nCc: \"Siddha, Suresh B\" \u003csuresh.b.siddha@intel.com\u003e\nCc: \"Rafael J.
