2017-03-03sched/headers: Remove the <linux/topology.h> include from <linux/sched.h>Ingo Molnar1-0/+7
It's used only by a single (rarely used) inline function (task_node(p)), which we can move to <linux/sched/topology.h>. ( Add <linux/nodemask.h>, because we rely on that. ) Acked-by: Linus Torvalds <torvalds@linux-foundation.org> Cc: Mike Galbraith <efault@gmx.de> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@kernel.org>
2017-03-03sched/headers: Remove <linux/sched.h> from <linux/sched/topology.h>Ingo Molnar1-2/+0
The <linux/sched/topology.h> file is a self-contained header and users of it either don't need <linux/sched.h> - or have already included it. This reduces the size of the header dependency graph.

2017-03-02sched/headers: Move scheduler topology interfaces to <linux/sched/topology.h>Ingo Molnar1-0/+213
The vast majority of sched.h users does not require the topology types and interfaces, so split them out into <linux/sched/topology.h>. This reduces the size of linux/sched.h by ~6%.

2017-03-02sched/headers: Prepare for new header dependencies before moving code to ↵Ingo Molnar1-0/+2
<linux/sched/idle.h> We are going to split <linux/sched/idle.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/idle.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.
