Factor out the the existing allocation and free operations
so that they can be used individually.
This is to improve code readability, and also to prepare for
possible future changes like better error recovery and more
dynamic configuration (e.g on-the-fly resizing of the rings).
This change represents a straight up relocation of the existing
code into separate routines without changing any of the contained
code itself. Local variables are relocated as necessary.

Since all that include/linux/if_ppp.h does is #include <linux/ppp-ioctl.h>,
this replaces the occurrences of #include <linux/if_ppp.h> with
#include <linux/ppp-ioctl.h>.
It also corrects an error in Documentation/networking/l2tp.txt, where
it referenced include/linux/if_ppp.h as the source of some definitions
that are actually now defined in include/linux/if_pppol2tp.h.

This moves the definitions of the ioctls, constants and structures
relating to the ppp_generic interface to userspace out from if_ppp.h
to a new file, ppp-ioctl.h. The new file has my copyright since I
designed and implemented the ppp_generic interface in the late 1990s.
None of the contents of this file comes from the original if_ppp.h
published by Carnegie Mellon University.
Of the remainder of if_ppp.h, only the PPP_MTU definition was being
used, and this replaces the uses of it with PPP_MRU (which is identical).
Therefore, this replaces the entire file with the single line
#include <linux/ppp-ioctl.h>
which clearly doesn't contain any CMU code. Thus I have removed the
CMU copyright notice with its problematic advertising clause, and in
fact since it's only one trivial line I have not added any other
copyright notice.

This changes the copyright notices on the PPP code that I developed
in the late 1990s from being copyright The Australian National
University to copyright Paul Mackerras. I can do this as I have an
acknowledgement in writing from the Head of the Computer Science
Department at ANU (where I worked then) that ANU does not claim any
intellectual property in this code.
While I'm at it, change the copyright notice from BSD-style to
GNU GPL like the rest of the kernel.

It's only used inside fs/dcache.c, and we're going to play games with it
for the word-at-a-time patches. This time we really don't even want to
export it, because it really is an internal function to fs/dcache.c, and
has been since it was introduced.
Having it in that extremely hot header file (it's included in pretty
much everything, thanks to <linux/fs.h>) is a disaster for testing
different versions, and is utterly pointless.
We really should have some kind of header file diet thing, where we
figure out which parts of header files are really better off private and
only result in more expensive compiles.

The original ColdFire timer interrupt setup is used by most of the users
of the original ColdFire timer code. But the code is currently duplicated
in each of the ColdFire CPU specific init files. Move it to the timers
code that it is really part of. It is strait forward to make it conditional
on also having the original interrupt engine that it needs.

We can move all the init calls in the initcall code into the more general
arch setup code (which is config_BSP() here). That makes the 532x consistent

The ColdFire QSPI is common to quite a few ColdFire CPUs. No need to duplicate
its platform setup code for every CPU family member that has it. Merge all the

This also results in few platforms no longer needing any local platform

code as well.
