Fix up conflicts in:
 - drivers/net/Kconfig:
	The split-up generated a trivial conflict with removal of a
	stale reference to Documentation/networking/net-modules.txt.
	Remove it from the new location instead.
 - fs/sysfs/dir.c:
	Fairly nasty conflicts with the sysfs rb-tree usage, conflicting
	with Eric Biederman's changes for tagged directories.

+/*  ewrk3.c: A DIGITAL EtherWORKS 3 ethernet driver for Linux.
+
+   Written 1994 by David C. Davies.
+
+   Copyright 1994 Digital Equipment Corporation.
+
+   This software may be used and distributed according to the terms of
+   the GNU General Public License, incorporated herein by reference.
+
+   This driver is written for the Digital Equipment Corporation series
+   of EtherWORKS ethernet cards:
+
+   DE203 Turbo (BNC)
+   DE204 Turbo (TP)
+   DE205 Turbo (TP BNC)
+
+   The driver has been tested on a relatively busy  network using the DE205
+   card and benchmarked with 'ttcp': it transferred 16M  of data at 975kB/s
+   (7.8Mb/s) to a DECstation 5000/200.
+
+   The author may be reached at davies@maniac.ultranet.com.
+
+   =========================================================================
+   This driver has been written  substantially  from scratch, although  its
+   inheritance of style and stack interface from 'depca.c' and in turn from
+   Donald Becker's 'lance.c' should be obvious.
+
+   The  DE203/4/5 boards  all  use a new proprietary   chip in place of the
+   LANCE chip used in prior cards  (DEPCA, DE100, DE200/1/2, DE210, DE422).
+   Use the depca.c driver in the standard distribution  for the LANCE based
+   cards from DIGITAL; this driver will not work with them.
+
+   The DE203/4/5 cards have 2  main modes: shared memory  and I/O only. I/O
+   only makes  all the card accesses through  I/O transactions and  no high
+   (shared)  memory is used. This  mode provides a >48% performance penalty
+   and  is deprecated in this  driver,  although allowed to provide initial
+   setup when hardstrapped.
+
+   The shared memory mode comes in 3 flavours: 2kB, 32kB and 64kB. There is
+   no point in using any mode other than the 2kB  mode - their performances
+   are virtually identical, although the driver has  been tested in the 2kB
+   and 32kB modes. I would suggest you uncomment the line:
+
+   FORCE_2K_MODE;
+
+   to allow the driver to configure the card as a  2kB card at your current
+   base  address, thus leaving more  room to clutter  your  system box with
+   other memory hungry boards.
+
+   As many ISA  and EISA cards  can be supported  under this driver  as you
+   wish, limited primarily  by the available IRQ lines,  rather than by the
+   available I/O addresses  (24 ISA,  16 EISA).   I have  checked different
+   configurations of  multiple  depca cards and  ewrk3 cards  and have  not
+   found a problem yet (provided you have at least depca.c v0.38) ...
+
+   The board IRQ setting   must be at  an unused  IRQ which is  auto-probed
+   using  Donald  Becker's autoprobe  routines.   All  these cards   are at
+   {5,10,11,15}.
+
+   No 16MB memory  limitation should exist with this  driver as DMA is  not
+   used and the common memory area is in low memory on the network card (my
+   current system has 20MB and I've not had problems yet).
+
+   The ability to load  this driver as a  loadable module has been included
+   and used  extensively during the  driver development (to save those long
+   reboot sequences). To utilise this ability, you have to do 8 things:
+
+   0) have a copy of the loadable modules code installed on your system.
+   1) copy ewrk3.c from the  /linux/drivers/net directory to your favourite
+   temporary directory.
+   2) edit the  source code near  line 1898 to reflect  the I/O address and
+   IRQ you're using.
+   3) compile  ewrk3.c, but include -DMODULE in  the command line to ensure
+   that the correct bits are compiled (see end of source code).
+   4) if you are wanting to add a new  card, goto 5. Otherwise, recompile a
+   kernel with the ewrk3 configuration turned off and reboot.
+   5) insmod ewrk3.o
+   [Alan Cox: Changed this so you can insmod ewrk3.o irq=x io=y]
+   [Adam Kropelin: now accepts irq=x1,x2 io=y1,y2 for multiple cards]
+   6) run the net startup bits for your new eth?? interface manually
+   (usually /etc/rc.inet[12] at boot time).
+   7) enjoy!
+
+   Note that autoprobing is not allowed in loadable modules - the system is
+   already up and running and you're messing with interrupts.
+
+   To unload a module, turn off the associated interface
+   'ifconfig eth?? down' then 'rmmod ewrk3'.
+
+   Promiscuous   mode has been  turned  off  in this driver,   but  all the
+   multicast  address bits  have been   turned on. This  improved the  send
+   performance on a busy network by about 13%.
+
+   Ioctl's have now been provided (primarily because  I wanted to grab some
+   packet size statistics). They  are patterned after 'plipconfig.c' from a
+   suggestion by Alan Cox.  Using these  ioctls, you can enable promiscuous
+   mode, add/delete multicast  addresses, change the hardware address,  get
+   packet size distribution statistics and muck around with the control and
+   status register. I'll add others if and when the need arises.

+	TODO, in rough priority order:
+	* Support forcing media type with a module parameter,
+	  like dl2k.c/sundance.c
+	* Constants (module parms?) for Rx work limit
+	* Complete reset on PciErr
+	* Jumbo frames / dev->change_mtu
+	* Adjust Rx FIFO threshold and Max Rx DMA burst on Rx FIFO error
+	* Adjust Tx FIFO threshold and Max Tx DMA burst on Tx FIFO error
+	* Implement Tx software interrupt mitigation via
+	  Tx descriptor bit

+
+    Originally,   this  driver  was    written  for the  Digital   Equipment
+    Corporation series of EtherWORKS ethernet cards:
+
+        DE425 TP/COAX EISA
+	DE434 TP PCI
+	DE435 TP/COAX/AUI PCI
+	DE450 TP/COAX/AUI PCI
+	DE500 10/100 PCI Fasternet
+
+    but it  will  now attempt  to  support all  cards which   conform to the
+    Digital Semiconductor   SROM   Specification.    The  driver   currently
+    recognises the following chips:
+
+        DC21040  (no SROM)
+	DC21041[A]
+	DC21140[A]
+	DC21142
+	DC21143
+
+    So far the driver is known to work with the following cards:
+
+        KINGSTON
+	Linksys
+	ZNYX342
+	SMC8432
+	SMC9332 (w/new SROM)
+	ZNYX31[45]
+	ZNYX346 10/100 4 port (can act as a 10/100 bridge!)
+
+    The driver has been tested on a relatively busy network using the DE425,
+    DE434, DE435 and DE500 cards and benchmarked with 'ttcp': it transferred
+    16M of data to a DECstation 5000/200 as follows:
+
+                TCP           UDP
+             TX     RX     TX     RX
+    DE425   1030k  997k   1170k  1128k
+    DE434   1063k  995k   1170k  1125k
+    DE435   1063k  995k   1170k  1125k
+    DE500   1063k  998k   1170k  1125k  in 10Mb/s mode
+
+    All  values are typical (in   kBytes/sec) from a  sample  of 4 for  each
+    measurement. Their error is +/-20k on a quiet (private) network and also
+    depend on what load the CPU has.
+
+    =========================================================================
+    This driver  has been written substantially  from  scratch, although its
+    inheritance of style and stack interface from 'ewrk3.c' and in turn from
+    Donald Becker's 'lance.c' should be obvious. With the module autoload of
+    every  usable DECchip board,  I  pinched Donald's 'next_module' field to
+    link my modules together.
+
+    Up to 15 EISA cards can be supported under this driver, limited primarily
+    by the available IRQ lines.  I have  checked different configurations of
+    multiple depca, EtherWORKS 3 cards and de4x5 cards and  have not found a
+    problem yet (provided you have at least depca.c v0.38) ...
+
+    PCI support has been added  to allow the driver  to work with the DE434,
+    DE435, DE450 and DE500 cards. The I/O accesses are a bit of a kludge due
+    to the differences in the EISA and PCI CSR address offsets from the base
+    address.
+
+    The ability to load this  driver as a loadable  module has been included
+    and used extensively  during the driver development  (to save those long
+    reboot sequences).  Loadable module support  under PCI and EISA has been
+    achieved by letting the driver autoprobe as if it were compiled into the
+    kernel. Do make sure  you're not sharing  interrupts with anything  that
+    cannot accommodate  interrupt  sharing!
+
+    To utilise this ability, you have to do 8 things:
+
+    0) have a copy of the loadable modules code installed on your system.
+    1) copy de4x5.c from the  /linux/drivers/net directory to your favourite
+    temporary directory.
+    2) for fixed  autoprobes (not  recommended),  edit the source code  near
+    line 5594 to reflect the I/O address  you're using, or assign these when
+    loading by:
+
+                   insmod de4x5 io=0xghh           where g = bus number
+		                                        hh = device number
+
+       NB: autoprobing for modules is now supported by default. You may just
+           use:
+
+                   insmod de4x5
+
+           to load all available boards. For a specific board, still use
+	   the 'io=?' above.
+    3) compile  de4x5.c, but include -DMODULE in  the command line to ensure
+    that the correct bits are compiled (see end of source code).
+    4) if you are wanting to add a new  card, goto 5. Otherwise, recompile a
+    kernel with the de4x5 configuration turned off and reboot.
+    5) insmod de4x5 [io=0xghh]
+    6) run the net startup bits for your new eth?? interface(s) manually
+    (usually /etc/rc.inet[12] at boot time).
+    7) enjoy!
+
+    To unload a module, turn off the associated interface(s)
+    'ifconfig eth?? down' then 'rmmod de4x5'.
+
+    Automedia detection is included so that in  principal you can disconnect
+    from, e.g.  TP, reconnect  to BNC  and  things will still work  (after a
+    pause whilst the   driver figures out   where its media went).  My tests
+    using ping showed that it appears to work....
+
+    By  default,  the driver will  now   autodetect any  DECchip based card.
+    Should you have a need to restrict the driver to DIGITAL only cards, you
+    can compile with a  DEC_ONLY define, or if  loading as a module, use the
+    'dec_only=1'  parameter.
+
+    I've changed the timing routines to  use the kernel timer and scheduling
+    functions  so that the  hangs  and other assorted problems that occurred
+    while autosensing the  media  should be gone.  A  bonus  for the DC21040
+    auto  media sense algorithm is  that it can now  use one that is more in
+    line with the  rest (the DC21040  chip doesn't  have a hardware  timer).
+    The downside is the 1 'jiffies' (10ms) resolution.
+
+    IEEE 802.3u MII interface code has  been added in anticipation that some
+    products may use it in the future.
+
+    The SMC9332 card  has a non-compliant SROM  which needs fixing -  I have
+    patched this  driver to detect it  because the SROM format used complies
+    to a previous DEC-STD format.
+
+    I have removed the buffer copies needed for receive on Intels.  I cannot
+    remove them for   Alphas since  the  Tulip hardware   only does longword
+    aligned  DMA transfers  and  the  Alphas get   alignment traps with  non
+    longword aligned data copies (which makes them really slow). No comment.
+
+    I  have added SROM decoding  routines to make this  driver work with any
+    card that  supports the Digital  Semiconductor SROM spec. This will help
+    all  cards running the dc2114x  series chips in particular.  Cards using
+    the dc2104x  chips should run correctly with  the basic  driver.  I'm in
+    debt to <mjacob@feral.com> for the  testing and feedback that helped get
+    this feature working.  So far we have  tested KINGSTON, SMC8432, SMC9332
+    (with the latest SROM complying  with the SROM spec  V3: their first was
+    broken), ZNYX342  and  LinkSys. ZYNX314 (dual  21041  MAC) and  ZNYX 315
+    (quad 21041 MAC)  cards also  appear  to work despite their  incorrectly
+    wired IRQs.
+
+    I have added a temporary fix for interrupt problems when some SCSI cards
+    share the same interrupt as the DECchip based  cards. The problem occurs
+    because  the SCSI card wants to  grab the interrupt  as a fast interrupt
+    (runs the   service routine with interrupts turned   off) vs.  this card
+    which really needs to run the service routine with interrupts turned on.
+    This driver will  now   add the interrupt service   routine  as  a  fast
+    interrupt if it   is bounced from the   slow interrupt.  THIS IS NOT   A
+    RECOMMENDED WAY TO RUN THE DRIVER  and has been done  for a limited time
+    until  people   sort  out their  compatibility    issues and the  kernel
+    interrupt  service code  is  fixed.   YOU  SHOULD SEPARATE OUT  THE FAST
+    INTERRUPT CARDS FROM THE SLOW INTERRUPT CARDS to ensure that they do not
+    run on the same interrupt. PCMCIA/CardBus is another can of worms...
+
+    Finally, I think  I have really  fixed  the module  loading problem with
+    more than one DECchip based  card.  As a  side effect, I don't mess with
+    the  device structure any  more which means that  if more than 1 card in
+    2.0.x is    installed (4  in   2.1.x),  the  user   will have   to  edit
+    linux/drivers/net/Space.c  to make room for  them. Hence, module loading
+    is  the preferred way to use   this driver, since  it  doesn't have this
+    limitation.
+
+    Where SROM media  detection is used and  full duplex is specified in the
+    SROM,  the feature is  ignored unless  lp->params.fdx  is set at compile
+    time  OR during  a   module load  (insmod  de4x5   args='eth??:fdx' [see
+    below]).  This is because there  is no way  to automatically detect full
+    duplex   links  except through   autonegotiation.    When I  include the
+    autonegotiation feature in  the SROM autoconf  code, this detection will
+    occur automatically for that case.
+
+    Command  line arguments are  now  allowed, similar  to passing arguments
+    through LILO. This will allow a per adapter board  set up of full duplex
+    and media. The only lexical constraints  are: the board name (dev->name)
+    appears in the list before its  parameters.  The list of parameters ends
+    either at the end of the parameter list or with another board name.  The
+    following parameters are allowed:
+
+            fdx        for full duplex
+	    autosense  to set the media/speed; with the following
+	               sub-parameters:
+		       TP, TP_NW, BNC, AUI, BNC_AUI, 100Mb, 10Mb, AUTO
+
+    Case sensitivity is important  for  the sub-parameters. They *must*   be
+    upper case. Examples:
+
+        insmod de4x5 args='eth1:fdx autosense=BNC eth0:autosense=100Mb'.
+
+    For a compiled in driver, at or above line 548, place e.g.
+	#define DE4X5_PARM "eth0:fdx autosense=AUI eth2:autosense=TP"
+
+    Yes,  I know full duplex isn't  permissible on BNC  or AUI; they're just
+    examples. By default, full duplex is turned off and  AUTO is the default
+    autosense setting.  In reality, I expect only  the full duplex option to
+    be used. Note the use of single quotes in the two examples above and the
+    lack of commas to separate items. ALSO, you must get the requested media
+    correct in relation to what the adapter SROM says it has. There's no way
+    to  determine this in  advance other than by  trial and error and common
+    sense, e.g. call a BNC connectored port 'BNC', not '10Mb'.
+
+    Changed the bus probing.  EISA used to be  done first,  followed by PCI.
+    Most people probably don't even know  what a de425 is today and the EISA
+    probe has messed  up some SCSI cards  in the past,  so now PCI is always
+    probed  first  followed by  EISA if  a) the architecture allows EISA and
+    either  b) there have been no PCI cards detected or  c) an EISA probe is
+    forced by  the user.  To force  a probe  include  "force_eisa"  in  your
+    insmod "args" line;  for built-in kernels either change the driver to do
+    this  automatically  or include  #define DE4X5_FORCE_EISA  on or  before
+    line 1040 in the driver.

+
+    Marcelo Tosatti <marcelo@conectiva.com.br> :
+    Made it compile in 2.3 (device to net_device)
+
+    Alan Cox <alan@lxorguk.ukuu.org.uk> :
+    Cleaned up for kernel merge.
+    Removed the back compatibility support
+    Reformatted, fixing spelling etc as I went
+    Removed IRQ 0-15 assumption
+
+    Jeff Garzik <jgarzik@pobox.com> :
+    Updated to use new PCI driver API.
+    Resource usage cleanups.
+    Report driver version to user.
+
+    Tobias Ringstrom <tori@unhappy.mine.nu> :
+    Cleaned up and added SMP safety.  Thanks go to Jeff Garzik,
+    Andrew Morton and Frank Davis for the SMP safety fixes.
+
+    Vojtech Pavlik <vojtech@suse.cz> :
+    Cleaned up pointer arithmetics.
+    Fixed a lot of 64bit issues.
+    Cleaned up printk()s a bit.
+    Fixed some obvious big endian problems.
+
+    Tobias Ringstrom <tori@unhappy.mine.nu> :
+    Use time_after for jiffies calculation.  Added ethtool
+    support.  Updated PCI resource allocation.  Do not
+    forget to unmap PCI mapped skbs.
+
+    Alan Cox <alan@lxorguk.ukuu.org.uk>
+    Added new PCI identifiers provided by Clear Zhang at ALi
+    for their 1563 ethernet device.
+
+    TODO
+
+    Check on 64 bit boxes.
+    Check and fix on big endian boxes.
+
+    Test and make sure PCI latency is now correct for all cases.

+				Theory of Operation
+
+I. Board Compatibility
+
+This driver is for the Winbond w89c840 chip.
+
+II. Board-specific settings
+
+None.
+
+III. Driver operation
+
+This chip is very similar to the Digital 21*4* "Tulip" family.  The first
+twelve registers and the descriptor format are nearly identical.  Read a
+Tulip manual for operational details.
+
+A significant difference is that the multicast filter and station address are
+stored in registers rather than loaded through a pseudo-transmit packet.
+
+Unlike the Tulip, transmit buffers are limited to 1KB.  To transmit a
+full-sized packet we must use both data buffers in a descriptor.  Thus the
+driver uses ring mode where descriptors are implicitly sequential in memory,
+rather than using the second descriptor address as a chain pointer to
+subsequent descriptors.
+
+IV. Notes
+
+If you are going to almost clone a Tulip, why not go all the way and avoid
+the need for a new driver?
+
+IVb. References
+
+http://www.scyld.com/expert/100mbps.html
+http://www.scyld.com/expert/NWay.html
+http://www.winbond.com.tw/
+
+IVc. Errata
+
+A horrible bug exists in the transmit FIFO.  Apparently the chip doesn't
+correctly detect a full FIFO, and queuing more than 2048 bytes may result in
+silent data corruption.
+
+Test with 'ping -s 10000' on a fast computer.
