be0976be91 [netdrvr] kill sync_irq-before-freq_irq pattern
synchronize_irq() is superfluous when free_irq() call immediately follows it,
because free_irq() also does a synchronize_irq() call of its own.

28cd4289ab [netdrvr] fealnx: clean up nasty mess of arch ifdefs
Clean up config/burst value arch-specific setup.

* bcrvalue only varied by its big-endian bit
* crvalue only varied for certain types of x86-32 chips

This should make fealnx quite a bit more portable, without any behavior
change.

f5ccbcfaca Fix forcedeth hibernate/wake-on-lan problems
This patch is the minimal amount of code needed to support
wake-on-lan in platform mode properly (i.e. "ethtool -s eth0 wol g"
is sufficient, no additional magic needed) for me.

This is derived from David Brownells patch
(http://lists.laptop.org/pipermail/devel/2007-April/004691.html).
However I decided to move the hook into pci-acpi.c since the other
two pci hooks also live there and pci and acpi are the only users of
the platform_enable_wakeup-hook.

As a 'side-effect' this also makes wake on usb activity work for me
and I had to disable usb wakeup (which is enabled by default) using
the power/wakeup sysfs functionality ("echo disabled >
${sysfs_path_to_device}/power/wakeup").

(BTW I first thought the 'immediate reboot because of usb wake' effect is
caused by the optical mouse generating a wake event, but it rather
seems to be a problem with a flaky secondary usb host controller,
which sees a connected device where nothing is attached)

9a60a82600 Fix forcedeth hibernate/wake-on-lan problems
We currently don't signal the kernel we that this device can wake
the system.  Call device_init_wakeup() to correct this.
Without this device_can_wakeup and device_may_wakeup will return
incorrect values.
Together with the minimized acpi wakeup patch (6/4 ;)), which will
follow in the next mail, this really makes wake-on-lan work for me
as expected (i.e. "ethtool -s eth0 wol g" is sufficient, no
additional magic needed).

b45f87681e e1000: remove e1000_clean_tx_irq call from e1000_netpoll
The call to e1000_clean_tx_irq in e1000_netpoll can race with the call
to e1000_clean_tx_irq in e1000_clean.  With a small bit of tweaking to
to netpoll_send_skb to simulate a system that was under extreme stress,
I was able to reproduce these concurrent calls.  This can result in
multiple frees to the skbs on the tx ring buffer.

Dropping this call from e1000_netpoll should be fine since we can rely
on the calls in e1000_clean to do what is needed since napi will poll
the hardware just after calling poll_controller.

a0a61a604c CONNECTOR: add a proc entry to list connectors
I got a problem when I wanted to check if the kernel supports process
event connector, and It seems there's no way to do this check.

At best I can check if the kernel supports connector or not, by looking
into /proc/net/netlink, or maybe checking the return value of bind() to
see if it's ENOENT.

So it would be useful to add /proc/net/connector to list all supported
connectors:
 # cat /proc/net/connector
 Name            ID
 connector       4294967295:4294967295
 cn_proc         1:1
 w1              3:1

Changelog:
- fix memory leak: s/seq_release/single_release
- use spin_lock_bh instead of spin_lock_irqsave

980dfcb932 rt2x00: Fix lock dependency errror
This fixes a circular locking dependency in the workqueue handling.
The interface work task uses the mac80211 function
ieee80211_iterate_active_interfaces() which grabs the RTNL lock.

However when the interface is brough down, this happens under the RTNL
lock as well, this causes problems because mac80211 will flush the workqueue
during the ifdown event. This causes mac80211 to wait until the driver has
completed all work which can't finish because it is waiting on the RTNL lock.

This is fixed by moving rt2x00 workqueue tasks on a different workqueue,
this workqueue can be flushed when the ieee80211_hw structure is removed
by the driver (when the driver is unloaded) which does not happen under the
RTNL lock.

64c42f6976 [netdrvr] Fix IOMMU overflow checking in s2io.c
s2io has IOMMU overflow checking, but unfortunately it is wrong.

It didn't use the standard macros, which meant that it only worked
on POWER and SPARC because only those define DMA_ERROR_CODE. Convert it to
use the standard macros instead.

I also commented two more bugs in the IOMMU handling. It assumes
that 0 DMA addresses cannot happen, but that's not true in all IOMMU setups.
The information if a buffer has been already mapped needs to be stored
elsewhere.

Didn't fix those because it needs careful checking of the buffer handling
by the maintainers.

looking at the driver I think the bug is real and the fix actually
is trivial.

vp->lock is also taken in hardware IRQ context, so we _have_ to always
use irqsafe locking. As we run in a timer with IRQs disabled,
we can simply use spin_lock.

99ade2597e rt2x00: Fix unbalanced mutex locking
The usb_cache_mutex was not correctly released
under all circumstances. Both rt73usb as rt2500usb
didn't release the mutex under certain conditions
when the register access failed. Obviously such
failure would lead to deadlocks.

In addition under similar circumstances when the
bbp register couldn't be read the value must be
set to 0xff to indicate that the value is wrong.
This too didn't happen under all circumstances.

2f9ec47d09 b43legacy: Fix possible NULL pointer dereference in DMA code
This fixes a possible NULL pointer dereference in an error path of the
DMA allocation error checking code. This is also necessary for a future
DMA API change that is on its way into the mainline kernel that adds
an additional dev parameter to dma_mapping_error().

78a6551814 drivers/net/tulip: update first comment in tulip files
Three basic changes to the comments at the top of each file:
1) remove stale "Maintained by" line...I prefer people look in MAINTAINERS.
2) Drop reference to stale sf.net/tulip website (I didn't see anything
   of value there)
3) Point people at bugzilla.kernel.org to submit bugs...will always
   get tracked regardless of who the maintainer is.

6ff4ff06d2 DM9000: Remove DEFAULT_TRIGGER for request_irq() flags.
Currently all but one user (AT91SAM9261EK) of the dm9000
driver passes their IRQ flags through the resources attached
to the platform device. This means we can remove the use
of DEFAULT_TRIGGER as the blackfin machines all seem to
have their triggers set properly.

f8dd0ecbb7 DM9000: Allow the use of the NSR register to get link status.
The DM9000's internal PHY reports a copy of the link status
in the NSR register of the chip. Reading the status when
polling for link status is faster as it eliminates the need
to sleep, but does not print as much information.

Add an platform flag to force this behaviour, and a Kconfig
option to allow it to be forced to the faster method always.

aa1eb452e8 DM9000: Use NSR to determine link-status on internal PHY
The DM9000_NSR register contains a copy of the internal PHY's
link status which we can use to determine if the link is up
or down. This eliminates the more costly (and sleeping) PHY
read when using the DM9000's own PHY.
