just drop these frames.

*On a previous patch i splitted AR5K_INT_TX to multiple different TX
interrupt flags for better handling but i forgot to unmask the new
TXDESC and TXEOL interrupts on ath5k_init and only left TXOK. However
for each queue we enable TXDESC and TXEOL interrupts, not TXOK so we don't
handle TX interrupts at all (because these interrupts remain masked on
PISR) and under load it results packet loss. Fix the problem by
unmasking TXDESC and TXEOL on ath5k_init.

8b0162a3dc ath5k: ignore the return value of ath5k_hw_noise_floor_calibration
Noise floor calibration occasionally fails on Atheros hardware.
This is not fatal and can happen if there's simply too much
noise on the air. Ignoring the calibration error is the right
thing to do here, because when the error is ignored, the hardware
will still work, whereas if the error causes the driver to bail out
of a bigger configuration function and does not configure the tx
queues or the IMR (as is the case in reset.c), the hw no longer
works properly until the next reset.

6d64360ac5 rt2x00: Fix BUG_ON() with antenna handling
With the new configuration handling, and more specifically
splitting the configuration of the antenna from the normal
configuration steps allowed a BUG_ON() to be triggered
in the driver because the SW_DIVERSITY was send to the
driver. This fixes that by catching the value early in
rt2x00config.c and replacing it with a sensible value.

This also fixes a problem where the antenna is not being
initialized at all when the radio is enabled. Since it
no longer is part of the mac80211 configuration the
only place where rt2x00 configured it was the SW diversity
handler. Obviously this is broken for all non-diversity
hardware and breaks SW diversity due to a broken initialization.

When the radio is enabled the antenna will be configured
once as soon as the config() callback function is called.

8058409c4f rt2x00: Block set_key() during suspend/shutdown
mac80211 will call set_key() when the device is
shutting down. When the device is unplugged the
keys will be lost automatically due to the power
loss. When the device is not plugged but the module
is only unloaded the keys can remain in the device
hardware, when the module is loaded the keys will
be cleaned up during initialization.

This should prevent the problem reported by Johannes Berg,
where unplugging the device while suspended resulted in
a NULL pointer error during set_key() which was
caused because of the CSR base address being freed.

9a95dba327 rt2x00: Fix LED state handling
For every global LED state change (register/unregister,
suspend/resume) we should force the LEDS to turn off.
This makes sure that the LEDS will always be in a sane
state after the state switch.

Note that when unregister is called but the LED class
wasn't resumed yet, we shouldn't change the LED state
since we might not have access to the device (device
was unplugged while suspended).

Also remove the checks in the activity, assoc and
radio LEDS which blocked calls to brightness_set()
when the state hasn't changed. Some of those LEDS
could be enabled by themselves when something happens
in the hardware (e.g. firmware is loaded). We already
did called rt2x00leds to switch the LED off, but those
calls were blocked.

b7b05fe7f9 ssb: struct device - replace bus_id with dev_name(), dev_set_name()
This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. The device
name is managed in the kobject anyway, and without any size
limitation, and just needlessly copied into "struct device".

To set and read the device name dev_name(dev) and dev_set_name(dev)
must be used. If your code uses static kobjects, which it shouldn't
do, "const char *init_name" can be used to statically provide the
name the registered device should have. At registration time, the
init_name field is cleared, to enforce the use of dev_name(dev) to
access the device name at a later time.

We need to get rid of all occurrences of bus_id in the entire tree
to be able to enable the new interface. Please apply this patch,
and possibly convert any remaining remaining occurrences of bus_id.

We want to submit a patch to -next, which will remove bus_id from
"struct device", to find the remaining pieces to convert, and finally
switch over to the new api, which will remove the 20 bytes array
and does no longer have a size limitation.

3d29b0c33d netdevice zd1201: Convert directly reference of netdev->priv to netdev_priv()
We have some reasons to kill netdev->priv:
1. netdev->priv is equal to netdev_priv().
2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
   netdev_priv() is more flexible than netdev->priv.
But we cann't kill netdev->priv, because so many drivers reference to it
directly.

OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug",
and I want to kill netdev->priv later, I decided to convert all the direct
reference of netdev->priv first.

(Original patch posted by Wang Chen <wangchen@cn.fujitsu.com> w/ above
changelog but using dev->ml_priv.  That doesn't seem appropriate
to me for this driver, so I've revamped it to use netdev_priv()
instead. -- JWL)

826dd0e1e3 netdevice ni65: Convert directly reference of netdev->priv
This patch is to kill directly reference of netdev->priv too.
Because the private data needs special memory: lower 16MB DMA.
alloc_etherdev() can not do this work.
So we can't use netdev->priv to point to netdev's private data.
Use netdev->ml_priv instead.

66e63ffbc0 mv643xx_eth: implement ->set_rx_mode()
Currently, if multiple unicast addresses are programmed into a
mv643xx_eth interface, the core networking will resort to enabling
promiscuous mode on the interface, as mv643xx_eth does not implement
->set_rx_mode().

This patch switches mv643xx_eth over from ->set_multicast_list()
to ->set_rx_mode(), and implements support for secondary unicast
addresses.  The hardware can handle multiple unicast addresses as
long as their first 11 nibbles are the same (i.e. are of the form
xx:xx:xx:xx:xx:xy where the x part is the same for all addresses), so
if that is the case, we use that mode.  If it's not the case, we enable
unicast promiscuous mode in the hardware, which is slightly better than
enabling promiscuous mode for multicasts as well, which is what would
happen before.

While we are at it, change the programming sequence so that we
don't clear all filter bits first, so we don't lose all incoming
packets while the filter is being reprogrammed.

37a6084f4b mv643xx_eth: introduce per-port register area pointer
The mv643xx_eth driver uses the rdl()/wrl() macros to read and
write hardware registers.  Per-port registers are accessed in the
following way:

	#define PORT_STATUS(p)			(0x0444 + ((p) << 10))

	[...]

	static inline u32 rdl(struct mv643xx_eth_private *mp, int offset)
	{
		return readl(mp->shared->base + offset);
	}

	[...]

	port_status = rdl(mp, PORT_STATUS(mp->port_num));

By giving the per-port 'struct mv643xx_eth_private' its own
'void __iomem *base' pointer that points to the per-port register
area, we can get rid of both the double indirection and the << 10
that is done for every per-port register access -- this patch does
that.

f1c0a2a3af USB: usbmon: fix read(2)
There's a bug in the usbmon binary reader: When using read() to fetch
the packets and a packet's data is partially read, the next read call
will once again return up to len_cap bytes of data. The b_read counter
is not regarded when determining the remaining chunk size.

So, when dumping USB data with "cat /dev/usbmon0 > usbmon.trace" while
reading from a USB storage device and analyzing the dump file
afterwards it will get out of sync after a couple of packets.

b09bc6cbae USB: fix SB700 usb subsystem hang bug
This patch is required for AMD SB700 south bridge revision A12 and A13 to avoid
USB subsystem hang symptom. The USB subsystem hang symptom is observed when the
system has multiple USB devices connected to it. In some cases a USB hub may be
required to observe this symptom.

This patch works around the problem by correcting the internal register setting
that will help by changing the behavior of the internal logic to avoid the
USB subsystem hang issue. The change in the behavior of the logic does not
impact the normal operation of the USB subsystem.

The LCD driver core calls LCD drivers when either the blanking state or
the display mode has changed, but does not make any check to see if the
called driver has a .set_mode method.

This means if a driver only has a .set_power method then the system will
OOPS on changing mode (and with the console semaphore held so you cannot
easily see the problem).

Fix the problem by ensuring that either callback is valid before use.

393df744e0 pxa2xx_spi: bugfix full duplex dma data corruption
Fixes a data corruption bug in pxa2xx_spi.c when operating in full duplex
mode with DMA and using buffers that overlap.

SPI transmit and receive buffers are allowed to be the same or to overlap.
 However, this driver fails if such overlap is attempted in DMA mode
because it maps the rx and tx buffers in the wrong order.  By mapping
DMA_FROM_DEVICE (read) before DMA_TO_DEVICE (write), it invalidates the
cache before flushing it, thus discarding data which should have been
transmitted.

The patch corrects the order of mapping.  This bug exists in all versions
of pxa2xx_spi.c; similar bugs are in the drivers for two other SPI
controllers (au1500, imx).

A version of this patch has been tested on kernel 2.6.20 using
verification of loopback data with: random transfer length, random
bits-per-word, random positive offsets (both larger and smaller than
transfer length) between the start of the rx and tx buffers, and varying
clock rates.

de339c2aa7 phylib: Fix auto-negotiation restart avoidance
A previous patch, 51e2a3846e, made
genphy_config_aneg() not restart aneg by calling genphy_restart_aneg() if
the advertisement hadn't changed.

But, genphy_restart_aneg() doesn't just restart aneg, it may also *enable*
aneg or un-isolate the PHY from the MII (those functions are controlled by
the same register).  The code to avoid calling genphy_restart_aneg() didn't
consider this.

So, modify genphy_config_aneg() to also check if the PHY needs to have aneg
enabled or be un-isolated before deciding not to restart aneg.

This caused a problem with certain Davicom PHYs, as that driver isolates
the PHY (why?) before calling genphy_config_aneg() and expects the PHY to
be un-isolated by that function.

I got the following warnings on IA64:

  linux-2.6/drivers/pci/intel-iommu.c: In function 'init_dmars':

Another victim of int-ll64.h versus int-l64.h confusion between platforms.

->reg_base_addr has a type of u64 - which can only be printed out
consistently if we cast its type up to LL.

[ Eventually reg_base_addr should be converted to phys_addr_t, for which
  we have the %pR printk helper - but that is out of the scope of late
  -rc's. ]

4018517a1a iwlagn: fix RX skb alignment
So I dug deeper into the DMA problems I had with iwlagn and a kind soul
helped me in that he said something about pci-e alignment and mentioned
the iwl_rx_allocate function to check for crossing 4KB boundaries. Since
there's 8KB A-MPDU support, crossing 4k boundaries didn't seem like
something the device would fail with, but when I looked into the
function for a minute anyway I stumbled over this little gem:

	BUG_ON(rxb->dma_addr & (~DMA_BIT_MASK(36) & 0xff));

Clearly, that is a totally bogus check, one would hope the compiler
removes it entirely. (Think about it)

After fixing it, I obviously ran into it, nothing guarantees the
alignment the way you want it,  because of the way skbs and their
headroom are allocated. I won't explain that here nor double-check that
I'm right, that goes beyond what most of the CC'ed people care about.

So then I came up with the patch below, and so far my system has
survived minutes with 64K pages, when it would previously fail in
seconds. And I haven't seen a single instance of the TX bug either. But
when you see the patch it'll be pretty obvious to you why.

This should fix the following reported kernel bugs:

http://bugzilla.kernel.org/show_bug.cgi?id=11596
http://bugzilla.kernel.org/show_bug.cgi?id=11393
http://bugzilla.kernel.org/show_bug.cgi?id=11983

I haven't checked if there are any elsewhere, but I suppose RHBZ will
have a few instances too...

I'd like to ask anyone who is CC'ed (those are people I know ran into
the bug) to try this patch.

I am convinced that this patch is correct in spirit, but I haven't
understood why, for example, there are so many unmap calls. I'm not
entirely convinced that this is the only bug leading to the TX reply
errors.

8e3bad65a5 mac80211: remove ieee80211_notify_mac
Before ieee80211_notify_mac() was added, it was presented with the
use case of using it to tell mac80211 that the association may
have been lost because the firmware crashed/reset.

Since then, it has also been used by iwlwifi to (slightly) speed
up re-association after resume, a workaround around the fact that
mac80211 has no suspend/resume handling yet. It is also not used
by any other drivers, so clearly it cannot be necessary for "good
enough" suspend/resume.

Unfortunately, the callback suffers from a severe problem: It only
works for station mode. If suspend/resume happens while in IBSS or
any other mode (but station), then the callback is pointless.

Recently, it has created a number of locking issues, first because
it required rtnl locking rather than RCU due to calling sleeping
functions within the critical section, and now because it's called
by iwlwifi from the mac80211 workqueue that may not use the rtnl
because it is flushed under rtnl.
(cf. http://bugzilla.kernel.org/show_bug.cgi?id=12046)

I think, therefore, that we should take a step back, remove it
entirely for now and add the small feature it provided properly.
For suspend and resume we will need to introduce new hooks, and for
the case where the firmware was reset the driver will probably
simply just pretend it has done a suspend/resume cycle to get
mac80211 to reprogram the hardware completely, not just try to
connect to the current AP again in station mode. When doing so, we
will need to take into account locking issues and possibly defer
to schedule_work from within mac80211 for the resume operation,
while the suspend operation must be done directly.

Proper suspend/resume should also not necessarily try to reconnect
to the current AP, the time spent in suspend may have been short
enough to not be disconnected from the AP, mac80211 will detect
that the AP went out of range quickly if it did, and if the
association is lost then the AP will disassoc as soon as a data
frame is sent. We might also take into account WWOL then, and
have mac80211 program the hardware into such a mode where it is
available and requested.

3f2c31d903 virtio_net: VIRTIO_NET_F_MSG_RXBUF (imprive rcv buffer allocation)
If segmentation offload is enabled by the host, we currently allocate
maximum sized packet buffers and pass them to the host. This uses up
20 ring entries, allowing us to supply only 20 packet buffers to the
host with a 256 entry ring. This is a huge overhead when receiving
small packets, and is most keenly felt when receiving MTU sized
packets from off-host.

The VIRTIO_NET_F_MRG_RXBUF feature flag is set by hosts which support
using receive buffers which are smaller than the maximum packet size.
In order to transfer large packets to the guest, the host merges
together multiple receive buffers to form a larger logical buffer.
The number of merged buffers is returned to the guest via a field in
the virtio_net_hdr.

Make use of this support by supplying single page receive buffers to
the host. On receive, we extract the virtio_net_hdr, copy 128 bytes of
the payload to the skb's linear data buffer and adjust the fragment
offset to point to the remaining data. This ensures proper alignment
and allows us to not use any paged data for small packets. If the
payload occupies multiple pages, we simply append those pages as
fragments and free the associated skbs.

This scheme allows us to be efficient in our use of ring entries
while still supporting large packets. Benchmarking using netperf from
an external machine to a guest over a 10Gb/s network shows a 100%
improvement from ~1Gb/s to ~2Gb/s. With a local host->guest benchmark
with GSO disabled on the host side, throughput was seen to increase
from 700Mb/s to 1.7Gb/s.
