[BRIDGE]: Do sysfs registration inside rtnl.
[NET]: Do sysfs registration as part of register_netdevice.

[IRDA]: Removing unused EXPORT_SYMBOLs
[IRDA]: New maintainer.
[NET]: Make netdev_chain a raw notifier.
[IPV4]: ip_options_fragment() has no effect on fragmentation
[NET]: Add missing operstates documentation.
The last step of netdevice registration was being done by a delayed
call, but because it was delayed, it was impossible to return any error
code if the class_device registration failed.
Side effects:
* one state in registration process is unnecessary.
* register_netdevice can sleep inside class_device registration/hotplug
* code in netdev_run_todo only does unregistration so it is simpler.

This is a backout of earlier patch.
The whole rescheduling hack was a bad idea. It doesn't really solve
the problem and it makes the code more complicated for no good reason.

After dwmw2 let me know it ought to be done, I rewrote the physmap map
driver to be a platform driver. I know zilch about the driver model,
so I probably botched it in some way, but I've done some tests on an
ixp23xx board which uses physmap, and it all seems to work.
In order to not break existing physmap users, I've added some compat
code that will instantiate a platform device iff CONFIG_MTD_PHYSMAP_LEN
is defined and != 0. Also, I've changed the default value for
CONFIG_MTD_PHYSMAP_LEN to zero, so that people who inadvertently
compile in physmap (or new, platform-style, users of physmap) don't get
burned.
This works pretty well -- the new physmap driver is a drop-in replacement
for the old one, and works on said ixp23xx board without any code changes
needed. (This should hold as long as users don't touch 'physmap_map'
directly.)
Once all physmap users have been converted to instantiate their own
platform devices, the compat code can go. (Or we decide that we can
change all the in-tree users at the same time, and never merge the
compat code.)

Atomically create attributes when class device is added. This avoids
the race between registering class_device (which generates hotplug
event), and the creation of attribute groups.

Extend the support of attribute groups in class_device's to allow
groups to be created as part of the registration process. This allows
network device's to avoid race between registration and creating
groups.
Note that unlike attributes that are a property of the class object,
the groups are a property of the class_device object. This is done
because there are different types of network devices (wireless for
example).

Nick says that the current construct isn't safe. This goes back to the
original, but sets PIPE_BUF_FLAG_LRU on user pages as well as they all
seem to be on the LRU in the first place.
