This changes sys_getppid() to be more POSIX-threading conformant.

sys_getppid() needs to return the PID of the "process' parent" (ie.  the
tgid of the parent thread), not the thread parent's PID.  The patch has
no effect on non-CLONE_THREAD users, for them current->group_leader ==
current.  The effect on CLONE_THREAD threads is that getppid() does not
return any PID within the thread group anymore.  Plus if a threaded
application starts up a (non-thread) child then the child sees the
process PID of the parent process, not the thread PID of the parent
thread.

in theory we could introduce the getttid() variant to get to the TID of
the parent thread, but i doubt it would be of any use.  (and we can add
it if the need arises.)

The lockless algorithm is still safe because the ->group_leader pointer
never changes asynchronously.  (the ->real_parent pointer might still
change asynchronously so the SMP checks are still needed.)

I've also updated the comments (they referenced the nonexistent p_ooptr
field.), plus i've changed the mb() to rmb() - we need to order the
reads, we dont do any global writes that need some predictable ordering.

This removes the include of (the now empty) Rules.make, gets rid of the
ifndef clause and fixes the indentation.

This fixes threaded coredumps and streamlines the code.  The old code
caused crashes and hung coredumps.  The new code has been tested for
some time already and appears to be robust.  Changes:

 - the code now uses completions instead of a semaphore and a waitqueue,
   attached to mm_struct:

        /* coredumping support */
        int core_waiters;
        struct completion *core_startup_done, core_done;

 - extended the completion concept with a 'complete all' call - all pending
   threads are woken up in that case.

 - core_waiters is a plain integer now - it's always accessed from under
   the mmap_sem. It's also used as the fastpath-check in the sys_exit()
   path, instead of ->dumpable (which was incorrect).

 - got rid of the ->core_waiter task flag - it's not needed anymore.

This corrects a small typo in the previous patch (in the ZOOM button
definition) and adds events generated by the Memory Stick reader on VAIO
U3 laptops (thanks to Kunihiko IMAI).

Badness results.

This implements the mmu stuff for the mmuless cpus - a lot of it stubs
to avoid ifdefs in core code

Basically a nop for MMU based systems
