2017-03-03sched/headers: Move the sched_exec() prototype to <linux/sched/task.h>Ingo Molnar
sched_exec() better fits into the task lifetime APIs than into the core scheduler APIs. This reduces the size of <linux/sched.h> a bit.

2017-03-03sched/headers: Move the get_task_struct()/put_task_struct() and related APIs ↵Ingo Molnar
from <linux/sched.h> to <linux/sched/task.h> These belong into the task lifetime API header.

2017-03-03sched/headers: Move exit_files() and exit_itimers() from <linux/sched.h> to ↵Ingo Molnar
<linux/sched/task.h> These two functions are task management related, not core scheduler APIs.

2017-03-03sched/headers: Move the task_lock()/unlock() APIs to <linux/sched/task.h>Ingo Molnar
The task_lock()/task_unlock() APIs are not realated to core scheduling, they are task lifetime APIs, i.e. they belong into <linux/sched/task.h>. Move them.

2017-03-03sched/headers: Move 'init_task' and 'init_thread_union' from <linux/sched.h> ↵Ingo Molnar
to <linux/sched/task.h> 'init_task' is really not part of core scheduler APIs but part of the fork() interface between the scheduler and process management. So move the declarations.

2017-03-03sched/headers, RCU: Move rcu_copy_process() from <linux/sched/task.h> to ↵Ingo Molnar
kernel/fork.c Move rcu_copy_process() into kernel/fork.c, which is the only user of this inline function. This simplifies <linux/sched/task.h> to the level that <linux/sched.h> does not have to be included in it anymore - which change is done in a subsequent patch.

2017-03-03sched/headers: Move task lifetime APIs from <linux/sched.h> to ↵Ingo Molnar
<linux/sched/task.h> There's a fair amount of task lifetime management (a.k.a fork()/exit()) related APIs in <linux/sched.h>, but only a small fraction of the users of the generic sched.h header make use of them. Move these functions to the <linux/sched/task.h> header.

2017-03-02sched/headers: Prepare for new header dependencies before moving code to ↵Ingo Molnar
<linux/sched/task.h> We are going to split <linux/sched/task.h> out of <linux/sched.h>, which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder <linux/sched/task.h> file that just maps to <linux/sched.h> to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.
