Add wireless statistics to /net/class/ethXX/wireless.

Now that unregister_sysfs got smaller, just eliminate it and call
class_device_unregister directly.  netdev_finish_unregister is called
one place, therefore it is easier to understand if we just put those
few lines into wait_allrefs state machine.

Net statistics were in a kobject only because there was no better way
to create a directory.  Latest 2.6.0-test3 bk tree, has merged in
Pat's change to provide 'attribute groups'.

This patch converts netdevice's from a statistic's kobject to attribute
group.  This is cleaner and fixes some shutdown unload issues as well.

Ps. it gets rid of of the object

   - define format strings once rather than N times
   - add GNU license that I forgot in original code
   - move read_lock out from format_address to show_address so
     device is alive test is inside of lock.

With the new module system MOD_INC/MOD_DEC are no longer necessary.
Also changed to new module init/exit macros for function setup.

The module exit code can sleep, so calling schedule_timeout is better
than spinning.

This patch adds support for the use of twofish and serpent as
ESP algorithms. The ESP index numbers given are in accordance
with RFC2407, draft-ietf-ipsec-ciph-aes-cbc-00 (before Rijndael
was selected), and KAME which assigns 253 to twofishcbc.

Support for using twofish was requested on linux-kernel, and
since I noticed serpent was missing too, included that as well.

  ia64: Fix prologue directives for sys_clone() and sys_clone2()

This has been in the -mm tree for a while and has helped a lot in finding
lots of improper users of the driver core.  It also moves the driver core
code up quite a few levels on the "Rusty's guide to kernel APIs".

A trailing else in the #ifdef CONFIG_USB_NET1080 block that would
prevent it from properly filling the bulk URB.

The code that manges the synchronous control/bulk calls has
been a mess for ages.  This patch rewrites it using:

 - "struct completion" instead of a usb-internal clone therof,
 - prepare_to_wait()/finish_wait() instead of the tangled
   mess it now uses (or a new wait_event_timeout call, as in
   previous versions of this patch).

It's a net code shrink and simplification.

Again, from Randy Dunlap

Based on patch from Randy Dunlap.

Need cacheflush.h for change_page_attr()

- sort some of the ATI entries. (note, there are dupes in there
  that could be fixed up at some point).
- Rename PCI_DEVICE_ID_RADEON_IGP to ATI_RS100.
  RadeonIGP is the family, not the specific chip.

If ->group_leader of current thread already was exiting,
group_leader's ->mm is NULL in fill_psinfo(). Then I got Oops.

This uses current->mm instead of ->group_leader->mm to dump args.

- Ensure that arq->state is always set (ie.  even if io context
  allocation failed).

- Call as_antic_stop() unconditionally - which checks for the same
  condition.  There are other callers which make the same check and should
  be changed too...
