Ingo Molnar ae1cc88232 sched/headers: Remove <linux/sched.h> from <linux/sched/coredump.h> 
The <linux/sched/coredump.h> file is a self-contained header and users of
it either don't need <linux/sched.h> - or have already included it.

Include <linux/mm_types.h>.

This reduces the size of the header dependency graph.

Ingo Molnar 11701c6768 sched/headers: Move task->mm coredumping related defines and methods from <linux/sched.h> to <linux/sched/coredump.h> 
This further reduces the size and complexity of <linux/sched.h>.

These are the definitions and APIs that are moved:

Ingo Molnar f7ccbae45c sched/headers: Prepare for new header dependencies before moving code to <linux/sched/coredump.h> 
We are going to split <linux/sched/coredump.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/coredump.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.
