  "message": "[IA64-SGI] - Reduce overhead of reading sn_topology\n\nMPI programs using certain debug options have a long\nstartup time. This was traced to a \"vmalloc/vfree\" in\nthe code that reads /proc/sgi_sn/sn_topology. On large\nsystems, vfree requires an IPI to all cpus to do TLB\npurging.\n\nReplace the vmalloc/vfree with kmalloc/kfree. Although\nthe size of the structure being allocated is unknown, it\nwill not not exceed 96 bytes.\n\nSigned-off-by: Jack Steiner \u003csteiner@sgi.com\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n",
