Christoph Lameter 71a2224d7d [PATCH] Optimize sys_times for a single thread process ...

Avoid taking the tasklist_lock in sys_times if the process is single
threaded.  In a NUMA system taking the tasklist_lock may cause a bouncing
cacheline if multiple independent processes continually call sys_times to
measure their performance.
