Forward port of LLC from 2.4 to 2.5. This is the forward port of the LLC stack
released by Procom Inc. for Linux 2.0.30, I have heavily modified it to make
it similar to other Linux network stacks, using of struct sk_buff to represent
in-transit packets and doing massive code cleanups.

Jay Schullist contributed support for BSD Sockets, as the original code had
only a simple in kernel API for use by upper layer protocols, such as the
NetBEUI stack also provided by Procom for 2.0.30.

This code is basically what I had previously submitted to Alan Cox for his
2.4-ac series and that is even shipped in source form, in the Red Hat 7.3
kernel package, plus cleanups wrt standard syntax for labeled elements and
further use of this C construct to make the code more resilient to editing
mistakes, using the compiler to further check the source code.

TODO:

Make it completely SMP safe, as the reports of successful usage up to now and
the testing is done on UP.

Completely remove the old LLC code in the kernel, that is still there for things
like Appletalk, IPX, etc to use, also check that all these protocols work
correctly with this new LLC stack.

This code is already being used in the linux-sna project and Jay Schullist
has been developing support for things like DLSw and other protocols that works
on top of 802.2.

I'll be releasing patches with the NetBEUI stack and updated samba-2.0.6 patches
for use with NetBEUI and this LLC stack in the future. But the NetBEUI code
is available already in my kernel.org ftp area at:

ftp://ftp.kernel.org/pub/linux/kernel/people/acme.

Please report problems to me or the linux-sna mailing list, instructions on how
to subscribe are available at http://www.linux-sna.org website.

Here is an updated patch for the floppy driver which got broken in
2.5.13. "read block 0 on ->revalidate()" is now implemented through
the bio interface, following a suggestion by Christoph Hellwig.

I still cannot explain why block_dev.c's ->bd_block_size change
caused data corruption, but removing that code fixes the floppy
driver and doesn't seem to cause any problems on my test box.

If our command line contains an ';', we'd only print half of
it and execute the other half - not good.

This patch removes the quicklist support and updates m68k to the recent
page table and tlb interface changes.
It also includes some smaller cleanups:
- turn "extern inline" into "static inline"
- convert some macros into inline functions

Removed the use of the next field due to the change in the urb structure.

Use the just introduced Rules.make extension to clean up 
drivers/net/*/Makefile.

New-style Makefiles have a nice way of declaring objects
which need to be built either built-in or as modules:

        obj-$(CONFIG_EEPRO100) += eepro100.o

However, handling objects in subdirectories, which need to be
built and linked is not as nice:

        subdir-$(CONFIG_E100) += e100

        ifeq ($(CONFIG_E100),y)
          obj-y += e100/built-in.o
        endif

This means we descend into the subdirectory when building
vmlinux / modules, depending on CONFIG_XXX. When we are building
vmlinux we also need to link whatever has been built in the
subdirectory, so we add it to $(obj-y) at the appropriate place
(link order is important).

Now, the extension below allows to rewrite the second case into

         obj-$(CONFIG_E100) += e100/

which looks much nicer ;-) Existing behavior is not changed, and the
only prerequisite to using the extension above is that the O_TARGET in
the subdir is named "built-in.o".

	Removes dev_unit() and messing with kdev_t in match_dev_unit()

	... is finally done.

Trivial patch update against 2.5.17:
Tim Schmielau <tim@physik3.uni-rostock.de>: move jiffies from sched.h to it's own jiffies.h:
  Move 'jiffies' from sched.h to their own header.
  Then pull the sched.h dependency from 67 files that include sched.h for
  no apparent reason other than the jiffies declaration.

  Move the time_[before,after}{_eq}() macros from timer.h to jiffies.h,
  since there are *no* files using them that don't also use jiffies.

  Many more sched.h dependencies can be killed after capable(),
  request_irq(), and free_irq() are moved out of <linux/sched.h>.

Trivial patch update against 2.5.17:
dipankar@in.ibm.com: smp_call_function change:
  My earlier patch fixed only i386. As per Dave Miller's suggestion,
  I have fixed smp_call_function for other smp architectures too.

  Description
  -----------
  Going by the documentation and use of _bh version of spin_lock(),
  smp_call_function() is allowed to be called from BH context,
  We can run into a deadlock with some locks if we do so.
  This because reader-writer locks can sometimes be used optimally
  by not disabling irqs while taking the reader side if only the
  reader side of the lock is taken from irq context.

        CPU #0                                CPU #1

        read_lock(&tasklist_lock)
                                         write_lock_irq(&tasklist_lock)
                                         [spins with interrupt disabled]
        [Interrupted by BH]
        smp_call_function() for BH
             handler
                                         [ doesn't take the IPI]

  So, cpu #1 doesn't take the IPI and cpu #0 spinwaits
  for the IPI handler to start, resulting in a deadlock.

  The last time I looked, I couldn't see smp_call_function() being
  called from BH context anywhere. So, there is no immediate problem.
  However it seems right to correct the documentation and also not
  disable BH while taking the call lock since it isn't necessary.
  This patch does exactly that.

  Thanks

Stephen Rothwell <sfr@canb.auug.org.au>: fix for sigio delivery:
  Hi Linus,

  This patch means that we keep the upper 16 bits of the si_code
  field of the siginfo structure that is delivered with and SIGIOs.
  We need this so that the code that actually copies the siginfo_t
  out to user mode knows which part of the union to copy.  We currently
  get away with out this information because we always copy at least
  two ints worth of the union, but this s an ugly hack and I would
  like to tidy it up.

   It seems all Ethernet device drivers were bulk-converted to use the new
  common CRC functions.  I discovered declance used incorrect endianness to
  calculate the sum for its multicast filter and had a few alignment
  problems there.  I fixed these bugs in the MIPS/Linux CVS tree which is at
  2.4.18 now.  Here is the respective update for the official kernel.

   The bugs make the filter non-functional.  Please apply.
