This patch pulls the PCI-related junk out of struct device_node and
puts it in a separate structure, struct pci_dn. The device_node now
just has a void * pointer in it, which points to a struct pci_dn for
nodes that represent PCI devices. It could potentially be used in
future for device-specific data for other sorts of devices, such as
virtual I/O devices.

In PPC64 there are number of problems in arch/ppc64/boot/main.c that
prevent a kernel from making use of a large (greater than ~16MB) INITRD.
This is 64 bit architecture and really large INITRD images should be
possible.
Simply put the existing code has a fixed reservation (claim) address and
once the kernel plus initrd image are large enough to pass this address
all sorts of bad things occur. The fix is the dynamically establish the
first claim address above the loaded kernel plus initrd (plus some
"padding" and rounding). If PROG_START is defined this will be used as
the minimum safe address - currently known to be 0x01400000 for the
firmwares tested so far.

This adds host-side RNDIS support to the "usbnet" driver, so Linux can talk
to various devices (often based on WinCE) that otherwise only Windows could
talk to.
Tested with little-endian Linux talking to a Linux-USB Ethernet/RNDIS based
peripheral. This also includes updates from Eddie C. Dost <ecd@brainaid.de>
for big-endian SPARC Linux talking to a Nokia 9500 Communicator.
It's still marked as EXPERIMENTAL because this code is so young. This
ought to let Linux to work with various cable modems that previously
would have been "Windows Only".

This patch moves the ASIX AX8817x driver into its own file, just using
the "usbnet" infrastructure as a utility library.
- As with "cdc_subset" this involved minor Kconfig/kbuild tweaks,
moving code from one file to another, and exporting a few functions.
- This includes updates from Jamie Painter to add (and use) a new hook
to handle the different maximum transfer sizes for rx and tx sides.
- Also from Jamie, some bugfixes:
* MDIO byteorder (to address some PPC media negotiation problems);
* Force alignment at key spots when using ax88772 framing (on some
embedded hardware, the network stack will break otherwise);
* Address some link reset problems.
It also makes this driver use the standard (5 seconds vs half second)
control timeouts used elsewhere in USB; and wraps a few lines before
the 80th column (which previously needed it).

This patch creates the first of several separate "minidriver" modules
for "usbnet". This one handles only the very simplest hardware, which
can be handled almost entirely by the "usbnet" core.
- Move device-specific bits into new "cdc_subset.c" driver,
shrinking "usbnet" by a bunch;
- Export the functions needed to support this minidriver
(with EXPORT_SYMBOL_GPL);
- Update Kconfig and kbuild accordingly.
This one handles about a dozen different device types, with the most
notable ones being Gumstix and most Linux-based PDAs (except Zaurus
running that ancient code from Sharp).

This starts to prepare the core of "usbnet" to know less about various
framing protocols that map Ethernet packets onto USB, so "minidrivers"
can be modules that just plug into the core.
- Remove some framing-specific code that cluttered the core:
* net->hard_header_len records how much space to preallocate;
now drivers that add their own framing (Net1080, GeneLink,
Zaurus, and RNDIS) will have smoother TX paths. Even for
the drivers (Zaurus, Net1080) that need trailers.
* defines new dev->hard_mtu, using this "hardware" limit to
check changes to the link's settable "software" mtu.
* now net->hard_header_len and dev->hard_mtu are set up in the
driver bind() routines, if needed.
- Transaction ID is no longer specific to the Net1080 framing;
RNDIS needs one too.
- Creates a new "usbnet.h" header with declarations that are shared
between the core and what will be separate modules.
- Plus a couple other minor tweaks, like recognizing -ESHUTDOWN
means the keventd work should just shut itself down asap.
The core code is only about 1/3 of this large file. Splitting out the
minidrivers into separate modules (e.g. ones for ASIX adapters,
Zaurii and similar, CDC Ethernet, etc), in later patches, will
improve maintainability and shrink typical runtime footprints.
