this is caused because the ns83820 driver re-enables irq flags
in hardirq context.

While legal in theory, in practice it should only be done if the
hardware is really old and has some very high overhead in its ISR.
(such as PIO IDE)

For modern hardware, running ISRs with irqs enabled is discouraged,
because 1) new hardware is fast enough to not cause latency problems
2) allowing the nesting of hardware interrupts only 'spreads out'
the handling of the current ISR, causing extra cachemisses that would
otherwise not happen. Furthermore, on architectures where ISRs share
the kernel stacks, enabling interrupts in ISRs introduces a much
higher kernel-stack-nesting and thus kernel-stack-overflow risk.
3) not managing irq-flags via the _irqsave / _irqrestore variants
is dangerous: it's easy to forget whether one function nests inside
another, and irq flags might be mismanaged.

In the few cases where re-enabling interrupts in an ISR is considered
useful (and unavoidable), it has to be taught to the lock validator
explicitly (because the lock validator needs the "no ISR ever enables
hardirqs" artificial simplification to keep the IRQ/softirq locking
dependencies manageable).

This teaching is done via the explicit use local_irq_enable_in_hardirq().
On a stock kernel this maps to local_irq_enable(). If the lock validator
is enabled then this does not enable interrupts.

Now, the analysis of drivers/net/ns83820.c's irq flags use: the
irq-enabling in irq context seems intentional, but i dont think it's
justified. Furthermore, the driver suffers from problem #3 above too,
in ns83820_tx_timeout() it disables irqs via local_irq_save(), but
then it calls do_tx_done() which does a spin_unlock_irq(),
re-enabling for a function that does not expect it! While currently
this bug seems harmless (only some debug printout seems to be
affected by it), it's nevertheless something to be fixed.

So this patch makes the ns83820 ISR irq-flags-safe, and cleans up
do_tx_done() use and locking to avoid the ns83820_tx_timeout() bug.

From: Arjan van de Ven <arjan@linux.intel.com>

  ns83820_mib_isr takes the misc_lock in IRQ context.  All other places that
  do this in the ISR already use _irqsave versions, make this consistent at
  least.  At some point in the future someone should audit the driver to see
  if all _irqsave's in the ISR can go away, this is generally an iffy/fragile
  proposition though; for now get it safe, simple and consistent.

From: Arjan van de Ven <arjan@linux.intel.com>

ok this is a real driver deadlock:

The ns83820 driver enabled interrupts (by unlocking the misc_lock with
_irq) while still holding the rx_info.lock, which is required to be irq
safe since it's used in the ISR like this:
                writel(1, dev->base + IER);
                spin_unlock_irq(&dev->misc_lock);
                kick_rx(ndev);
                spin_unlock_irq(&dev->rx_info.lock);

This is can cause a deadlock if an irq was pending at the first
spin_unlock_irq already, or if one would hit during kick_rx().
Simply remove the first _irq solves this

Daniel Drake e85d0918b5 [PATCH] ZyDAS ZD1211 USB-WLAN driver
There are 60+ USB wifi adapters available on the market based on the ZyDAS
ZD1211 chip.

Unlike the predecessor (ZD1201), ZD1211 does not have a hardware MAC, so most
data operations are coordinated by the device driver. The ZD1211 chip sits
alongside an RF transceiver which is also controlled by the driver. Our driver
currently supports 2 RF types, we know of one other available in a few marketed
products which we will be supporting soon.

Our driver also supports the newer revision of ZD1211, called ZD1211B. The
initialization and RF operations are slightly different for the new revision,
but the main difference is 802.11e support. Our driver does not support the
QoS features yet, but we think we know how to use them.

This driver is based on ZyDAS's own GPL driver available from www.zydas.com.tw.
ZyDAS engineers have been responsive and supportive of our efforts, so thumbs
up to them. Additionally, the firmware is redistributable and they have
provided device specs.

This driver has been written primarily by Ulrich Kunitz and myself. Graham
Gower, Greg KH, Remco and Bryan Rittmeyer have also contributed. The
developers of ieee80211 and softmac have made our lives so much easier- thanks!

We maintain a small info-page: http://zd1211.ath.cx/wiki/DriverRewrite

If there is enough time for review, we would like to aim for inclusion in
2.6.18. The driver works nicely as a STA, and can connect to both open and
encrypted networks (we are using software-based encryption for now). We will
work towards supporting more advanced features in the future (ad-hoc, master
mode, 802.11a, ...).

Jeff Garzik c3d8e682b7 [netdrvr] Remove Becker-template 'io_size' member, when invariant
Becker-derived drivers often have the 'io_size' member in their chip
info struct, indicating the minimum required size of the I/O resource
(usually a PCI BAR).  For many situations, this number is either
constant or irrelevant (due to pci_iomap convenience behavior).

This change removes the io_size invariant member, and replaces it with a
compile-time constant.

Jeff Garzik 03a8c6611a [netdrvr] Remove Linux-specific changelogs from several Becker template drivers
When in-kernel net drivers branched from Donald Becker's vanilla driver
set, in the days before BitKeeper and git, a driver changelog was
maintained in the driver source code.  These days, the kernel's
changelog is far superior and much more accurate, so the in-driver
changelogs are removed.

Another relic of the Becker/kernel split was version numbering, using
"foo-LKx.y.z" notation, resulting in weird version numbers like
"1.17b-LK1.1.9".  These drivers are for older hardware, and see few
changes these days, so the version numbers were all bumped to something
more simple.

Finally, in xircom_tulip_cb specifically, an additional cleanup removes
the always-enabled CARDBUS cpp macro.

ok this appears to be hostap playing games... it has 2 network devices
for one piece of hardware and one calls the other via the networking
layer; there is thankfully a natural ordering between the two, so just
making the slave one a separate type ought to make this work.

Ingo Molnar 0a9da4bd8e [PATCH] lockdep: annotate 3c59x.c disable_irq()
3c59x.c's vortex_timer() function knows that vp->lock can only be used by an
irq context that it disabled - and can hence take the vp->lock without
disabling hardirqs.  Teach lockdep about this.

Has no effect on non-lockdep kernels.

Sam Ravnborg 63104eec23 kbuild: introduce utsrelease.h
include/linux/version.h contained both actual KERNEL version
and UTS_RELEASE that contains a subset from git SHA1 for when
kernel was compiled as part of a git repository.
This had the unfortunate side-effect that all files including version.h
would be recompiled when some git changes was made due to changes SHA1.
Split it out so we keep independent parts in separate files.

Also update checkversion.pl script to no longer check for UTS_RELEASE.

Benjamin Herrenschmidt 0ebfff1491 [POWERPC] Add new interrupt mapping core and change platforms to use it
This adds the new irq remapper core and removes the old one.  Because
there are some fundamental conflicts with the old code, like the value
of NO_IRQ which I'm now setting to 0 (as per discussions with Linus),
etc..., this commit also changes the relevant platform and driver code
over to use the new remapper (so as not to cause difficulties later
in bisecting).

This patch removes the old pre-parsing of the open firmware interrupt
tree along with all the bogus assumptions it made to try to renumber
interrupts according to the platform. This is all to be handled by the
new code now.

For the pSeries XICS interrupt controller, a single remapper host is
created for the whole machine regardless of how many interrupt
presentation and source controllers are found, and it's set to match
any device node that isn't a 8259.  That works fine on pSeries and
avoids having to deal with some of the complexities of split source
controllers vs. presentation controllers in the pSeries device trees.

The powerpc i8259 PIC driver now always requests the legacy interrupt
range. It also has the feature of being able to match any device node
(including NULL) if passed no device node as an input. That will help
porting over platforms with broken device-trees like Pegasos who don't
have a proper interrupt tree.

Herbert Xu f83ef8c0b5 [IPV6]: Added GSO support for TCPv6
This patch adds GSO support for IPv6 and TCPv6.  This is based on a patch
by Ananda Raju <Ananda.Raju@neterion.com>.  His original description is:

	This patch enables TSO over IPv6. Currently Linux network stacks
	restricts TSO over IPv6 by clearing of the NETIF_F_TSO bit from
	"dev->features". This patch will remove this restriction.

	This patch will introduce a new flag NETIF_F_TSO6 which will be used
	to check whether device supports TSO over IPv6. If device support TSO
	over IPv6 then we don't clear of NETIF_F_TSO and which will make the
	TCP layer to create TSO packets. Any device supporting TSO over IPv6
	will set NETIF_F_TSO6 flag in "dev->features" along with NETIF_F_TSO.

	In case when user disables TSO using ethtool, NETIF_F_TSO will get
	cleared from "dev->features". So even if we have NETIF_F_TSO6 we don't
	get TSO packets created by TCP layer.

	SKB_GSO_TCPV4 renamed to SKB_GSO_TCP to make it generic GSO packet.
	SKB_GSO_UDPV4 renamed to SKB_GSO_UDP as UFO is not a IPv4 feature.
	UFO is supported over IPv6 also

	The following table shows there is significant improvement in
	throughput with normal frames and CPU usage for both normal and jumbo.

bug may be triggered when the TSO header size is greater than 80

problem and collecting traces to help debug the problem.

. reworked event setting so that it occurs after the MII setup.
  roucaries bastien <roucaries.bastien@gmail.com>
. Do not read cbd_sc in memory for each bit we test. Once per buffer is enough.
. Overrun errors must increase `rx_fifo_errors', not `rx_crc_errors'
. No need for a special value to activate rx or tx.  Only write access matters.
. Simplify parameter of eth_copy_and_sum : `data' has already the right value.
. Some spelling fixes.

* ich8 specific read/write code
* flash/nvm access code
* software semaphore flag functions
* 10/100 PHY (fe - no gigabit speed) support for low-end versions
* A workaround for a powerdown sequence problem discovered that

Auke Kok 2db10a081c e1000: rework driver hardware reset locking
After studying the driver mac reset code it was found that there
were multiple race conditions possible to reset the unit twice or
bring it e1000_up() double. This fixes all occurences where the
driver needs to reset the mac.

We also remove irq requesting/releasing into _open and _close so
that while the device is _up we will never touch the irq's. This fixes
the double free irq bug that people saw.

To make sure that the watchdog task doesn't cause another race we let
it run as a non-scheduled task.

Jeff Garzik 1f1bd5fc32 [netdrvr] Remove long-unused bits from Becker template drivers
Symbols such as PCI_USES_IO, PCI_ADDR0, etc. originated from Donald
Becker's net driver template, but have been long unused.  Remove.

In a few drivers, this allows the further eliminate of the pci_flags (or
just plain flags) member in the template driver probe structure.

Most of this logic is simply open-coded in most drivers, since it never
changes.

Made a few other cleanups while I was in there, too:
* constify, __devinitdata several PCI ID tables
* replace table terminating entries such as "{0,}," and "{NULL},"
  with a more-clean "{ }".

The phy ids used are taken from an driver that used a right shift of 4 to chop
off the revision number.  This driver does not shift, so the id and mask
values are wrong and must be left shifted by 4 to actually detect the chips.
