- Let real-time tasks dip further into the reserves than usual in
  __alloc_pages().  There are a lot of ways to special case this.  This
  patch just cuts z->pages_low in half, before doing the incremental min
  thing, for real-time tasks.  I do not do anything in the low memory slow
  path.  We can be a _lot_ more aggressive if we want.  Right now, we just
  give real-time tasks a little help.

- Never ever call balance_dirty_pages() on a real-time task.  Where and
  how exactly we handle this is up for debate.  We could, for example,
  special case real-time tasks inside balance_dirty_pages().  This would
  allow us to perform some of the work (say, waking up pdflush) but not
  other work (say, the active throttling).  As it stands now, we do the
  per-processor accounting in balance_dirty_pages_ratelimited() but we
  never call balance_dirty_pages().  Lots of approaches work.  What we want
  to do is never engage the real-time task in forced writeback.

Split the increasingly messy compiler.h file into per-compiler files and also
add support for non-gcc compilers.  

With the current implementation:

  include/linux/compiler.h defines the compiler-dependent abstractions
  which can be overwritten by per-compiler definitions.

  include/linux/compiler-gcc.h contains the common definitions for all gcc
  versions.

  include/linux/compiler-gcc[2,3,+].h contains gcc major version specific
  definitions.

  include/linux/compiler-intel.h contains intel compiler specific
  definitions."

- declarations come first

- fix bizarre coding style.

The problem was that the semaphore which prevents ds interfering with
the sleepy card initialisation (skt_sem in pccardd) is blocking insmod
of the socket driver.  However, the socket driver is being called with
the PCI bus semaphore held by the driver model.

pccardd in turn discovered a cardbus card (with skt_sem held), so it
is trying to add the PCI devices to the PCI bus, and this requires the
driver model to grab the PCI bus semaphore, but its already locked.

We move the class device register into pccardd so we get a natural
ordering between the ds socket initialisation and pccardd trying to
detect inserted cards.

We also fix a potential use-after-free caused by rmmod'ing the socket
driver before ds has shut down.

Don't issue a system call from kernel_thread(), but call do_fork()
directly.  This avoids all the unnecessary syscall overhead.

It's bad to make (CLONE_THREAD | CLONE_DETACHED) tasks
be _completely_ hidden. Resource consumption is hard
to track down if a user can hide a task from /bin/ps.

This patch, supported by the procps-3.1.13 release,
gives admins the ability to search for such tasks.
The top-level /proc directory remains uncontaminated.

When I change the setting of CONFIG_EISA, everything rebuilds.  This is
because EISA_bus is declared in <asm/processor.h> which is implicitly
included by just about everything.  This is a silly place to declare it,
so this patch moves it to include/linux/eisa.h.

While I'm at it, I also move the variable definition to
drivers/eisa/eisa-bus.c.  The rest of this patch is fixing up the fallout
from having to include <linux/eisa.h> if you use EISA_bus.

automatically as needed.

Remove duplicate includes, ensure that linux/config.h is included
where necessary, and linux/config.h isn't included where it isn't
needed.

Small clean up, to use current APIs.

this one fixes both drivers. They have been broken since the
reorganization in June. Unfortunately, my major build platform (alpha) had
some issues with later 2.5.X kernels (cache problems causing all kind of
funny behaviour), so i waited until these problems had been resolved by
the alpha gurus :-/...

In the mean time i also upgraded pine. I hope the patch corruption issue
is resolved by now.

Update hamradio/scc for 2.6.0-test5
	- use seq_file for /proc
	- get rid of dev_get()
	- use alloc_netdev

Don't have hardware, but can load/unload the module fine.

This patch converts /proc/net/bondX/info into /proc/net/bonding/bondX
using the seq_file interface.

This is based on Stephen's recent patch, but slightly modified to work
with the propagation patch set and with some locking changes to make it
simpler.

The patch applies both on 2.4 (after the sync set from earlier today)
and on 2.6 (after the propagation set from 2003/11/9).

sbni.c in 2.6.0-test5 fails to compile with gcc 3.3 with the following
error:

Below is the patch by Margit Schubert-White to fix this issue (it is
already in 2.4).

So it will.  I blame the gcc developers.

Redo of earlier patch to get rid of MOD_INC/DEC and use alloc_netdev.
This is against 2.6.0-test5 bk latest.

Update sealevel driver to match current net_device interface:
	- dynamically allocate netdevice and private data.
	- get rid of MOD_INC/DEC
	- if_ptr not used
	- bugfix: not all of board structure was being zeroed.

Note: this driver still doesn't probe() correctly since it just assumes that
if loaded the hardware is there!

Since I don't have one of these boards...
tested it by #ifdef'ing out all the bits that touch actual hardware.

Convert ali-ircc driver to:
	- use alloc_net_dev not dev_alloc
	- allocate private data at same time
	- cleanup error unwinds
	- call free_netdev.

Builds and loads, but don't have real hardware.

Convert via-ircc 2.6.0-test5
	- use alloc_net_dev not dev_alloc
	- allocate private data at same time
	- cleanup error unwinds
	- call free_netdev.

Builds and loads, but don't have real hardware.

Cleanup nsc-ircc driver for 2.6.0-test5
	- replace dev_alloc with alloc_netdev
	- use private data allocated with alloc_netdev
	- error unwind cleanup

Fixes for donauboe for 2.6.0-test5
	- replace dev_alloc with alloc_netdev
	- error unwind cleanup
