Add oprofile calltrace support to powerpc. Disable spinlock backtracing
now we can use calltrace info.
(Updated to work on both 32bit and 64bit by me).

In 2.6.15-git6 a change was commited in the oprofile support in
the powerpc architecture. It introduced the powerpc_oprofile_type
which contains the define G4. This causes a name clash with the
existing wacom usb tablet driver.
CC [M] drivers/usb/input/wacom.o
drivers/usb/input/wacom.c:98: error: conflicting types for `G4'
include/asm/cputable.h:37: error: previous declaration of `G4'

The elements of an enum declared in global scope are effectivly
global identifiers themselves. As such we need to ensure the names
are unique. This patch updates the later oprofile support to use
unique names.

My recent changes to oprofile broke it when built as a module. Fix it by
using an enum instead of a function pointer. This way we still retain
the oprofile configuration in the cputable.

This patch adds oprofile support for the 7450 and all its multitudinous
derivatives.
* Added 7450 (and derivatives) support for oprofile
* Changed e500 cputable to have oprofile model and cpu_type fields
* Added support for classic 32-bit performance monitor interrupt
* Cleaned up common powerpc oprofile code to be as common as possible
* Cleaned up oprofile_impl.h to reflect 32 bit classic code
* Added 32-bit MMCRx bitfield definitions and SPR numbers

This patches the ppc32 and ppc64 versions of the headers and .c files
with helper functions for manipulating the performance counting
hardware. As a side effect, it removes use of the term "perfmon" from
ppc32, thus avoiding confusion with the unrelated performance counter
interface from HP Labs also called "perfmon".
Built, but not booted, for g5, pSeries, iSeries, and 32-bit Powermac
with both ARCH=powerpc and ARCH=ppc{,64} as appropriate.

Changed ppc32 so that cur_cpu_spec is just a single pointer for all CPUs.
Additionally, made call_setup_cpu check to see if the cpu_setup pointer
is NULL or not before calling the function. This lets remove the dummy
cpu_setup calls that just return.
