Jack Steiner dd4cb9f8ac [IA64-SGI] - Reduce overhead of reading sn_topology ... MPI programs using certain debug options have a long startup time. This was traced to a "vmalloc/vfree" in the code that reads /proc/sgi_sn/sn_topology. On large systems, vfree requires an IPI to all cpus to do TLB purging. Replace the vmalloc/vfree with kmalloc/kfree. Although the size of the structure being allocated is unknown, it will not not exceed 96 bytes.
