I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.
In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.
My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:
arch/alpha/kernel/err_common.c

I would welcome test reports for these files. I am fine with removing
the untested files from the patch if the general opinion is that these
changes aren't safe. The tested part would still be nice to have.
Note that this patch depends on another header fixup patch I submitted

In commit 0fba3a1f39f8b0a50b56c8b068fa52131cbc84c2 (a very long time ago,
May 2006), I fixed a bug that caused powermacs to crash when you tried
entering standby/mem suspend states.
As I'm now getting more familiar with the suspend code I notice a few
more things:
1. we previously misunderstood what pm_ops is for, it isn't supposed to be
for doing platform dependent suspend/resume stuff that needs to be done
for suspend to disk (as we currently try to use it!), it is instead for
entering platform dependent suspend states ("standby", "mem").
2. due to the first point, we never properly save FPU and altivec states
when suspending to disk. It probably hasn't hurt yet because the process
that writes the "disk" to /sys/power/state uses neither and its context
is used.
This patch addresses these points as follows:
1. remove all pm_ops from powermac, powermac suspend to ram isn't currently
usable via /sys/power/state but is done via the PMU instead.
2. move the code responsible for storing FPU/altivec state into
save_processor_state and the set_context() call to restore_processor_state.
3. add a call to kernel_enable_spe()
It may look like there is some code removal missing but that is
actually because the new suspend.h file overrides the ppc/suspend.h
one which was previously used.

Since we don't have it active by default, the STRICT_MM_TYPECHECKS
option has bitrotted again. This patch fixes a couple of simple build
fixes if the option is selected. First, pud_t mustn't be defined in
page.h on 32-bit systems, because it conflicts with the version in the
generic pud-folding code. Second, pci_32.c is missing a __pgprot()
wrapper call. Third, a couple of PS3 files use constants of type
pgprot_t when they need the raw values, we add pgprot_val() calls to
fix this.

Some versions of pSeries firmware fail to set up a
dma-window property for PCI slots that are unoccupied.
As a result, the loop searching for this propery, in
pci_dma_dev_setup_pSeriesLP(), can run to the end, resulting
in a NULL pointer dereference later in the routine. This
patch prevents the crash, and prints a warning message.
This is theoretically a rare error, as it occurs on what
is hopefully just beta levels of firmware. But just in case
this firmware escapes into the wild, this patch will avoid
the crash.

The original code here is wrong, it applies "previous" knowledge.
The way the cpufreq core is designed is that the policy for the
secondary CPU that comes online says that it must in fact not
use this policy but use the same as the other CPUs that are
listed, which in fact is CPU#0.

Now that we always take a device tree in arch/powerpc, there's no good
reason not to allow a single kernel to support multiple embedded 4xx
boards - the correct platform code can be selected based on the device
tree information.
Therefore, this patch re-arranges the 4xx Kconfig code to allow this.
In addition we:
- use "select" instead of depends to configure the correct
config options for specific 4xx CPUs and workarounds, which
makes the information about specific boards and CPUs less
scattered.
- Some old, unused (in arch/powerpc) config options are
removed: WANT_EARLY_SERIAL, IBM_OCP, etc.
