The host controllers have to be fixed up before we can safely take
out the check for dev->state.

This patch merges the USB state definitions from the ARM Linux
code (inside the sa1100 driver) and uses them to track what can
be done with the device.  That replaces the recently added
"udev->present" flag with a more complete/standard state model.

There are a few changes that might affect behavior if things
start to go really haywire:

 - usb_set_address() and usb_set_configuration(), used while
   enumerating, handle some unlikely cases more correctly:
   don't allow setting address to zero (undefined behavior),
   and do allow un-configuring (config 0).  (Adds a FIXME
   for an existing set-configuration bug too.)

 - usb_disconnect() flags the state change earlier (as soon
   as it's known).

 - usb_submit_urb() works in the states where messaging is
   allowed, and also enforces the "unless configured, only
   control traffic is legal" rule.

 - usb_unlink_urb() doesn't care any more about that state.
   (There seemed to be agreement that it must not matter.)

This will help with some further cleanups in the complex of
issues relating to driver removal, device removal, config
changing (with driver unbind and rebind), reset, and so on.

This patch fixes an oversight in usb-storage whereby the command length
and command buffer for an automatically-generated REQUEST-SENSE command
would not be initialized properly.

Thanks to gene_heskett@iolinc.net for the info for this.

attached a fix for the io_edgeport usb serial driver
This diff fixes endianess issues which prevented the driver to work on
bigendian machines (e.g. sparc).

 sync with Nagano's version:
 - protect vendors ids against multiple definitions
 - sort Roland device ids
 - fix SC-8850 cable bitmask
 - add quirk for the SC-8820
 - add quirk for the MOTU Fastlane

Finally...

Many places use inappropriate types for comparing jiffies,
int for example.  Fix those places up.

 - Cleanup Makefile.
 - Fix potentional crash in dv1394 module unload.
 - Why does ARM's memcpy not return void*? Oh well, work around it in
  eth1394 by not expecting standard behavior.

 - Inode and dcache Hash table only needs half the memory/cache because
   of using hlists.
 - Simplify dcache-rcu code.  With NULL end markers in the hlists
   is_bucket is not needed anymore.  Also the list walking code
   generates better code on x86 now because it doesn't need to dedicate
   a register for the list head.
 - Reorganize struct dentry to be more cache friendly.  All the state
   accessed for the hash walk is in one chunk now together with the
   inline name (all at the end)
 - Add prefetching for all the list walks.  Old hash lookup code didn't
   use it.
 - Some other minor cleanup.

Originally from Nikita Danliov. 

- Add struct subsystem to struct file_system_type. 
- Add fs_subsys_init() to explicitly call sysfs_init() very early.
- Register base fs subsystem then, too.
- Register filesystems' embedded subsystem when registered with fs core.

Resulting tree looks like:

# tree /sys/fs/
/sys/fs/
|-- bdev
|-- devpts
|-- eventpollfs
|-- ext2
|-- ext3
|-- futexfs
|-- iso9660
|-- pipefs
|-- proc
|-- ramfs
|-- rootfs
|-- sockfs
|-- sysfs
`-- tmpfs

- For matching registered platform devices with platform drivers.

- Also, make sure platform_bus is initialized early, with the rest of the 
  core stuff.

This ensures that sysfs is initialized very early, before anything can 
possibily registered with it. 

It happens early enough that all filesystems can registered with sysfs 
(besides sysfs itself), which is coming next.

- Call driver_init() from init/main.c::do_basic_setup(). 

This ensures that all the driver model subsystems are initialized before
any drivers or devices can be registered. 

It nearly frees up the core and postcore initcall levels, making them 
available for other kernel code to use freely. 

From Andrew Morton

- Add ioctl32 compat function registration for video1394, dv1394 and
  amdtp.
- Convert SBP-2 driver to new SCSI hotplug host/device interfaces.
- Initial Async ISO (GASP) support.

- Create and register kobjects when adding a cpu to the cpufreq interface,
  instead of the terminally broken struct intf_data.

- Remove struct intf_data. 
  It was silly, and gave us an unbalanced interface. 
  Instead, when removing a device_interface, all of a class's devices are
  iterated over, and intf->remove_device() is called for each. (Instead 
  of the device's list of interfaces it belongs to). 
  Interfaces are expected to tell if they support the device being removed.

- Remove struct device::intf_list.

- Protect classes' device list access with devclass_sem, which is taken 
  when a device or interface is added or removed. This allows access to the
  list w/o taking the class's lock, which allows subordinate objects to be
  registered (e.g. the interface itself, or objects the interfaces create
  for a device). 

- This should fix a deadlock when devices are added to interfaces, which 
  calls intf->add_device(), then interface_add_data(), which call 
  kobject_register() and hangs, since it tries to take the class's lock
  again. 

Check whether kset is NULL or not before doing container_of().

From Matt Wilcox

If a file that doesn't exist was looked up in a directory, and that
directory is later removed, sysfs would reap the negative dentrys along 
with the valid ones.

Fix is to manually remove the dentrys from the parent's list under the 
dcache_lock, then check if they're valid with dget_locked(). 

This ensures all the dentrys are removed, valid and invalid, and we don't 
reap anything we shouldn't.
