sched/headers: Prepare for new header dependencies before moving code to <linux/sched/mm.h>
We are going to split <linux/sched/mm.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/mm.h> file that just maps to <linux/sched.h> to make this patch obviously correct and bisectable.
The APIs that are going to be moved first are:
mm_alloc() __mmdrop() mmdrop() mmdrop_async_fn() mmdrop_async() mmget_not_zero() mmput() mmput_async() get_task_mm() mm_access() mm_release()
Include the new header in the files that are going to need it.

powerpc: remove non-required uses of include <linux/module.h>
None of the files touched here are modules, and they are not exporting any symbols either -- so there is no need to be including the module.h. Builds of all the files remains successful.
Even kernel/module.c does not need to include it, since it includes linux/moduleloader.h instead.

[POWERPC] spufs: fix rescheduling of non-runnable contexts
At present, we can hit the BUG_ON in __spu_update_sched_info by reading the regs file of a context between two calls to spu_run. The spu_release_saved called by spufs_regs_read() is resulting in the (now non-runnable) context being placed back on the run queue, so the next call to spu_run ends up in the bug condition.
This change uses the SPU_SCHED_SPU_RUN flag to only reschedule a context if it's still in spu_run().

[POWERPC] spufs: fix invalid scheduling of forgotten contexts
At present, we have a situation where a context with no owner is re-scheduled by spu_forget:
Thread 1: reading regs file Thread 2: context owner
spu_forget() - ctx->owner = NULL - set SPU_SCHED_WAS_ACTIVE
spu_acquire_saved() - context is in saved state
spu_release_saved() - SPU_SCHED_WAS_ACTIVE is set, so spu_activate() the context, which now has no owner
In spu_forget(), we shouldn't be requesting a re-schedule by setting SPU_SCHED_WAS_ACTIVE. This change removes the set_bit in spu_forget(), so that spu_release_saved() doesn't reinsert this destroyed context on to the run queue.

There are a few places where we get called e.g. from spufs teardown routines were we can't simply err out so these are left with a comment. For now I've also not touched the poll routines because it's open what libspe would expect in terms of interrupted system calls.

[POWERPC] spusched: Fix initial timeslice calculation
Currently we calculate the first timeslice for every context incorrectly - alloc_spu_context calls spu_set_timeslice before we set ctx->prio so we always calculate the longest possible timeslice for the lowest possible priority.
This patch makes sure to update the schedule-related fields before calculating the timeslice and also makes sure we update the timeslice for a non-running context when entering spu_run so a priority change affects the context as soon as possible.

[CELL] oprofile: add support to OProfile for profiling CELL BE SPUs
From: Maynard Johnson <mpjohn@us.ibm.com>
This patch updates the existing arch/powerpc/oprofile/op_model_cell.c to add in the SPU profiling capabilities. In addition, a 'cell' subdirectory was added to arch/powerpc/oprofile to hold Cell-specific SPU profiling code. Exports spu_set_profile_private_kref and spu_get_profile_private_kref which are used by OProfile to store private profile information in spufs data structures.
Also incorporated several fixes from other patches (rrn). Check pointer returned from kzalloc. Eliminated unnecessary cast. Better error handling and cleanup in the related area. 64-bit unsigned long parameter was being demoted to 32-bit unsigned int and eventually promoted back to unsigned long.

Having separate patches was making the review process harder than it should, as we end up integrating spus and ctx statistics accounting much more than it was on the first implementation.
