The Sprint 4G network uses a Wimax dongle with Beecem
chipset. The driver is typical of out of tree drivers, but
maybe useful for people, and the hardware is readily available.

Here is a staging ready version (i.e warts and all)

0. Started with Rel_5.2.7.3P1_USB from Sprint4GDeveloperPack-1.1
1. Consolidated files in staging
2. Remove Dos cr/lf
3. Remove unnecessary ioctl from usbbcm_fops

Applied patches that were in the developer pack, surprising
there were ones for 2.6.35 already.

This is compile tested only, see TODO for what still needs
to be done.

Jiri pointed out that the previous compiler warning fix was incorrect as
the compiler was properly saying that the variable was not being set.
This was due to a #define commenting out all of the logic in the
function.

This patch reverts Javier's previous one, and properly fixes the issue
by making the function actually doing something.

Fix fb_defio bug in udlfb for multiple framebuffers

Previously when using fb_defio with multiple DisplayLink attached displays
udlfb incorrectly used a shared datastructure where it needed to have

In each case, the function has an unsigned return type, but returns a
negative constant to indicate an error condition.  For move_block_from_dma,
there is only one call and the return value is dropped, so it need not be
unsigned.  For labpc_eeprom_write, there is only one call and the result is
stored in a signed variable, so again the unsigned return type is not
necessary.

A sematic match that finds this problem is as follows:

Add module options for console and fb_defio

Convert fb_defio on/off switch to module option and add console option.

>From the command line, pass options to modprobe
modprobe udlfb defio=1 console=1

Or for permanent option, create file like /etc/modprobe.d/options with text
options udlfb defio=1 console=1

Accepted options:

fb_defio	Make use of the fb_defio (CONFIG_FB_DEFERRED_IO) kernel
		module to track changed areas of the framebuffer by page faults.
        	Standard fbdev applications that use mmap but that do not
		report damage, may be able to work with this enabled.
		Disabled by default because of overhead and other issues.

console		Allow fbcon to attach to udlfb provided framebuffers. This
		is disabled by default because fbcon will aggressively consume
		the first framebuffer it finds, which isn't usually what the
		user wants in the case of USB displays.

Support writing default/backup edid via /sys/class/graphics/fb?/edid

Writing a backup edid blob to the 'edid' file will cause udlfb to
attempt to re-read the edid from hardware.
If we still don't have a good edid, it will use the backup edid instead.
The intent is to 1) enable user-supplied edid
2) enable udev rules to backup the last known good edid
for a device, and then provide that edid as a backup for all future starts

Enhance EDID and mode table handling

* Adds support for lower-end DL chips on higher-end monitors
* Adds support for using fbdev standard EDID parsing and handling
* Adds support for more dynamic reallocation of framebuffer, based on new EDID

Queries EDID from hardware with several retries then
queries DisplayLink chip for max pixel area via vendor descriptor.
Uses existing fbdev mode handling service funcations to build mode list
of common modes between adapter and monitor.
This enables lower-end chips (e.g. DL-125) to successfully pick a compatible
mode on higher end monitors (e.g. whose default mode is over 1280x1024).
Reallocate framebuffer if necessary in response to new max mode.

Revamp reference handling and synchronization for unload/shutdown

Udlfb is a "virtual" framebuffer device that really exists on
two separate stacks: at the bottom of the framebuffer interface,
and on top of USB.  During unload, there's no guarantee which
one will tear down first. So reference counting must be solid
to handle all possibilities and not access anything once its gone.

batman_if has the name of the net_dev as extra string in its own
