[PATCH] BSD accounting speedup

From: Ingo Molnar <mingo@elte.hu>

Most distributions turn on process accounting - but even the common
'accounting is off' case is horrible SMP-scalability-wise: it accesses a
global spinlock during every sys_exit() call, which bounces like mad on SMP
(and NUMA) systems.

(i also got rid of the unused return code.)
