This patch modifies the driver to support the ipw2200-fw-3.0 image format.
The 3.0 fw image does not add any new capabilities, but as a result of
image format changes, it should fix two problems experienced by users:
1) Race conditions with the request_firmware interface and udev/hotplug
are improved as only a single request_firmware call is now required to
load the firmware and microcode (vs. 3 separate calls previously)
2) The monitor mode firmware (sniffer) is now packaged with the correct
boot image so it can now function without frequent restarts.
Note: Once you apply this patch, you will also need to upgrade your
firmware image to the 3.0 version available from:

Set a meaningful silence threshold value (replacing our previous "0"
default), which gets rid of the gratuitous "Link deterioration"
notifications that we've been receiving from firmware. This
notification feature tells the driver information to help it determine
when to pre-emptively restart the firmware/ucode in anticipation of
firmware errors! But since setting this new threshold, I haven't seen
any such notifications. At least it keeps the logs a little less busy.

The patch roll back the change we made to support for the ability to
start/stop independent Tx queues within a single net device in order to
support 802.11e QoS. We need to be able to indicate to the upper layers
that packets of a given priority can not be sent any more without halting
transmission of all packets, and without rescheduling high priority packets
down to the next priority level.
So we return NETDEV_TX_BUSY in this case and rely on the stack would
take care of rescheduling... which it apparently does immediately and
consumes the CPU. This caused the ksoftirqd kernel thread consuming almost
all the CPU...
To put the code back to the way it was before we made these changes we
put the call netif_queue_stop back in ipw_tx_skb. This effectively
disables multiple priority based transmit queues for 802.11e, but given
that its broken anyway...

As stated in a comment, the ipw2200 driver uses several routines that
were borrowed from ieee80211_geo.c. As ipw2200 requires ieee80211,
these routines are duplicated. The attached patch, which is sent
as an attachment to preserve whitespace, converts ipw2200.c to use
the ieee80211 versions, thereby reducing bloat in both the source
and binary.

The dm-stripe target currently does not enforce that the size of a stripe
device be a multiple of the chunk-size. Under certain conditions, this can
lead to I/O requests going off the end of an underlying device. This
test-case shows one example.
echo "0 100 linear /dev/hdb1 0" | dmsetup create linear0
echo "0 100 linear /dev/hdb1 100" | dmsetup create linear1
echo "0 200 striped 2 32 /dev/mapper/linear0 0 /dev/mapper/linear1 0" | \
dmsetup create stripe0
dd if=/dev/zero of=/dev/mapper/stripe0 bs=1k
This will produce the output:
dd: writing '/dev/mapper/stripe0': Input/output error
97+0 records in
96+0 records out
And in the kernel log will be:
attempt to access beyond end of device
dm-0: rw=0, want=104, limit=100
The patch will check that the table size is a multiple of the stripe
chunk-size when the table is created, which will prevent the above striped
device from being created.
This should not affect tools like LVM or EVMS, since in all the cases I can
think of, striped devices are always created with the sizes being a
multiple of the chunk-size.
The size of a stripe device must be a multiple of its chunk-size.
(akpm: that typecast is quite gratuitous)

someone, the bdev and inode creation is done with the fake device info and the
following partition detection code is just using the wrong data.

Add DMA workaround for chips that do not support full 64-bit DMA
addresses.
5714, 5715, and 5780 chips only support DMA addresses less than 40
bits. On 64-bit systems with IOMMU, set the dma_mask to 40-bit so
that pci_map_xxx() calls will map the DMA address below 40 bits if
necessary. On 64-bit systems without IOMMU, set the dma_mask to
64-bit and check for DMA addresses exceeding the limit in
tg3_start_xmit().
5788 only supports 32-bit DMA so need to set the mask appropriately
also.
Thanks to Chris Elmquist at SGI for reporting and helping to debug
the problem on 5714.

Rather than checking for some known failures, check positively for the
success response code 0x0001 and return -EIO for unrecognized failure
response codes.

If the same ttyIx device was opened by two processes the module was not
released and so the usage count went never to zero again. This oneliner fixes
the issue.

The SCSI layer uses SCSI_SENSE_BUFFERSIZE (96) for the sense buffer
size, even though some other code uses "sizeof(struct request_sense)"
(which is 64 bytes). Allocate the buffer using the bigger of the two
for safety.

This fixes a use-after-free bug in the usb-serial core. It is simple to
trigger this (open a usb-serial port, then yank the device out before
closing the port.) Thanks to Stefan Seyfried <seife@suse.de> for
reporting this, and to the slab debugging code which enabled it to be
tracked down.
