The Atmel MACB Ethernet peripheral is also integrated in the AT91SAM9260
and AT91SAM9263 processors.  The differences from the AVR32 version are:
      * Single peripheral clock.
      * MII/RMII selection bit is inverted.
      * Clock enable bit.

At some point someone added a spin_lock(&dev->lock) to the IRQ handler for
the Z85230 driver.  This actually correctly fixes a bug but the necessary
changes to remove the chan->lock calls in the event handlers were not made
(c->lock is the same lock).

Simona Dascenzo reported the problem with the driver and this patch should
fix the problem he found.

The problem.  When implementing a network namespace I need to be able
to have multiple network devices with the same name.  Currently this
is a problem for /sys/class/net/*. 

What I want is a separate /sys/class/net directory in sysfs for each
network namespace, and I want to name each of them /sys/class/net.

I looked and the VFS actually allows that.  All that is needed is
for /sys/class/net to implement a follow link method to redirect
lookups to the real directory you want. 

Implementing a follow link method that is sensitive to the current
network namespace turns out to be 3 lines of code so it looks like a
clean approach.  Modifying sysfs so it doesn't get in my was is a bit
trickier. 

I am calling the concept of multiple directories all at the same path
in the filesystem shadow directories.  With the directory entry really
at that location the shadow master. 

The following patch modifies sysfs so it can handle a directory
structure slightly different from the kobject tree so I can implement
the shadow directories for handling /sys/class/net/.

This allows us to add type specific attributes, uevent vars and
release funtions.

A subsystem can carry different types of devices like the "block"
subsys has disks and partitions. Both types create a different set
of attributes, but belong to the same subsystem.

This corresponds to the low level objects:
  kobject   -> device       (object/device data)
  kobj_type -> device_type  (type of object/device we are embedded in)
  kset      -> class/bus    (list of objects/devices of a subsystem)

if a driver returns an error in fill_read_buffer(), the buffer will be

This patch prevents a race between IO and removing a file from sysfs.
It introduces a list of sysfs_buffers associated with a file at the inode.
Upon removal of a file the list is walked and the buffers marked orphaned.
IO to orphaned buffers fails with -ENODEV. The driver can safely free
associated data structures or be unloaded.
