sched: Split cpuacct code out of sched.h Add cpuacct.h and let sched.h include it. Signed-off-by: Li Zefan <lizefan@huawei.com> Acked-by: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/5155367B.2060506@huawei.com Signed-off-by: Ingo Molnar <mingo@kernel.org>

sched/cpuacct: Simplify the cpuacct code - Use for() instead of while() loop in some functions to make the code simpler. - Use this_cpu_ptr() instead of per_cpu_ptr() to make the code cleaner and a bit faster.
