This is the minimal resume trace code to find which device resume (if
any) results in problems. Usually, you'd use the information this
generates as a starting point to adding more fine-grained trace event
points.

Considering that there isn't a lot of hw we can depend on during resume,
this is about as good as it gets.
This is x86-only for now, although the basic concept (and most of the
code) will certainly work on almost any platform.

ring_head is offset in card memory, not iomem pointer. Fixed, removed
fuckloads of amazingly bogus casts somebody had sprinkled all over the
place.

I severely apologize, I was still learning how to program
in C when I wrote this stuff 10 years ago...

Sparcspkr and power drivers are converted, to make sure it works.
Eventually the SBUS device layer will use this as a sub-class.
I really cannot cut loose on that bit until sparc32 is given the
same infrastructure.

Import some more stuff from powerpc.
Add of_device_is_compatible(), and of_find_compatible_node().
Export some more of the other routines to modules.

One thing this change pointed out was that we really should
pull the "get 'local-mac-address' property" logic into a helper
function all the network drivers can call.

Otherwise the in-kernel PROM device tree isn't built yet,
and therefore the present cpu bits don't get set properly.

On some sun4v systems, after netboot the ethernet controller and it's
DMA mappings can be left active. The net result is that the kernel
can end up using memory the ethernet controller will continue to DMA
into, resulting in corruption.
To deal with this, we are more careful about importing IOMMU
translations which OBP has left in the IO-TLB. If the mapping maps
into an area the firmware claimed was free and available memory for
the kernel to use, we demap instead of import that IOMMU entry.
This is going to cause the network chip to take a PCI master abort on
the next DMA it attempts, if it has been left going like this. All
tests show that this is handled properly by the PCI layer and the e1000
drivers.

If we end up zero'ing out the size of one of the entries,
pop it out of the array completely because some code that
examines these things cannot handle a zero length element
properly.

The basic framework is based on the PowerPC OF code.
This code even tries to get the device addressing components
correct in the full path names.
