fb1c8f93d869b34cacb8b8932e2b83d96a19d720 broke the ARM rwlock code since
it only partially updated the rwlock implementation. Properly update it.

Patch from John Bowler
Fix for a compiler warning, this wasn't apparent in 2.6.12, I
believe the compiler options have been changed (somewhere) so
that passing a (void*) to a (u32) argument is now warned.
This accounts for the majority of the warnings in my builds of
the 2.6.14 kernel for NSLU2.
The patch changes pointer parameters declared as u32 to be
declared as either, for read parameters:
const volatile void __iomem *
and for write parameters:
volatile void __iomem *

The PIT timer in the 5208 ColdFire has slightly different interrupt
bit definitions than the PIT timer used on other ColdFire parts.
Define the commonly used bit and mask numbers here, and let
part specific defines take precedence if they are defined.

These days, the NACA only exists on iSeries. Therefore, this patch
moves naca.h from include/asm-ppc64 to arch/powerpc/platforms/iseries.
There was one file including naca.h outside of platforms/iseries -
arch/ppc64/kernel/udbg_scc.c. However, that's obviously a hangover
from older days. The include is not necessary, so this patch simply
removes it.
Built and booted on iSeries, built for G5 (which uses udbg_scc.o).

asm-ppc64/dart.h is included in exactly one place -
arch/powerpc/sysdev/u3_iommu.c. This patch, therefore, moves it into
arch/powerpc/sysdev. While we're at it, update the #ifndef/#define
protecting the include, and the filename in the comments of
u3_iommu.c.

The ppc64 versions of numnodes.h and sparsemem.h can be safely moved
to asm-powerpc with no changes apart from changing the #define to the
standard _ASM_POWERPC_ form. There are no ppc32 versions of these
files, because they only have any effect if CONFIG_SPARSEMEM is
enabled, which it never can be on ppc32.

This patch merges the ppc32 and ppc64 versions of futex.h, essentially
by taking the ppc64 version as the powerpc version. The old ppc32
version did not implement the futex_atomic_op_inuser() callback (it
always returned -ENOSYS), so FUTEX_WAKE_OP would not work on ppc32.
In fact the ppc64 version of this function is almost suitable for
ppc32 as well - the only change needed is to extend ppc_asm.h with a
macro expanding to to the right pseudo-op to store a pointer (either
".long" or ".llong").
Built and booted on pSeries. Built for 32-bit powermac.

Patch from Lennert Buytenhek
This patch adds a microcode loader for the ixp2000 architecture.
The ixp2000 is an xscale-based CPU with a number of additional small
CPUs ('microengines') on die that can be programmed to do various
things. Depending on the ixp2000 model, there are between 2 and 16
microengines.
This code provides an API that allows configuring the microengines,
loading code into them, and starting and stopping them and reading
out a number of status registers, and is used by the microengine
network driver that was recently announced to netdev.
