Hi
Hi all,
I'm so sorry, please ignore this patch set!

Preempt_schedule() has set PREEMPT_ACTIVE before calling
__schedule() and __schedule will check it if current state is not
TASK_RUNNING, avoiding this preemption.

sched/debug: Fix sd->*_idx li
Commit 201c373e8e ("sched/debug: Limit sd->*_idx range on sysctl")
was an incomplete bug fix. This patch fixs sd->*_idx limit range to
[0 ~ CPU_LOAD_IDX_MAX - 1] avioding array overflow caused by setting
sd->*_idx to CPU_LOAD_IDX_MAX on sysctl.

The comment of function rebalance_domains mentions arch_init_sched_domains,
but this function don't exist. The proper function is init_sched_domains.
