Subject: [POWERPC] spufs: fix possible memory corruption is spufs_mem_write

Due to a buggy unsigned comparison, it was possible to write
beyond the end of the local store file in spufs under some
circumstances.

This rewrites the buggy function to look more like
simple_copy_from_buffer.

This optimization was added recently but is still buggy,
so back it out for now.

Subject: [POWERPC] Fix spu SLB invalidations

The SPU code doesn't properly invalidate SPUs SLBs when necessary,
for example when changing a segment size from the hugetlbfs code. In
addition, it saves and restores the SLB content on context switches
which makes it harder to properly handle those invalidations.

This patch removes the saving & restoring for now, something more
efficient might be found later on. It also adds a spu_flush_all_slbs(mm)
that can be used by the core mm code to flush the SLBs of all SPEs that
are running a given mm at the time of the flush.

In order to do that, it adds a spinlock to the list of all SPEs and move
some bits & pieces from spufs to spu_base.c

Subject: [POWERPC] ps3: always make sure were running on a PS3

Add missing checks to PS3 specific drivers ps3av and sys-manager to verify that
we are actually running on a PS3 (pointed out by Arnd).

Correct existing checks in other subsystems/drivers to return -ENODEV instead
of zero.
