The size of the incoming frame is not correctly checked.
The RxMaxSize register (0xDA) does not work as expected and incoming
frames whose size exceeds the MTU actually end spanning multiple
descriptors. The first Rx descriptor contains the size of the whole
frame (or some garbage in its place). The driver does not expect
something above the space allocated to the current skb and crashes
loudly when it issues a skb_put.
The fix contains two parts:
- disable hardware Rx size filtering: so far it only proved to be able
to trigger some new fancy errors;
- drop multi-descriptors frame: as the driver allocates MTU sized Rx
buffers, it provides an adequate filtering.
As a bonus, wrong descriptors were not returned to the asic after their
processing.

Adds an ignore_disconnect module parameter. When enabled, the driver
will continue attempting to send packets even when the firmware has
told us we've lost our link to the AP. On some firmwares this
substantially increases the usable range of the card (presumably
because we have an interrmittent connection, but the firmware is able
to queue the packets for us until we're connected again). On some
other cards, it causes the firmware to fall in a screaming heap :(
(hence, default off).

Here's a patch for -mm for now. Not sure whose territory this falls
in, so I'm sending it to everyone I can think of. :)
Some time ago I did some experiments with using PPP multilink over
largish numbers of channels (up to 32). The TCP performance was
woeful due to wildly fluctuating packet latencies, which turned out to
be because we would sometimes split a packet across all 32 channels,
and sometimes we would send a whole packet down a single channel.
This patch fixes those problems by being a bit cleverer about how the
packets are split across the available channels, and in particular, it
waits until at least half of the channels can take another fragment
before starting to split up the next packet.
The patch also fixes a buglet in the multilink reconstruction code
where it would discard incoming packets that had just the multilink
header and no data. Such packets are valid and shouldn't be
discarded.

o VP-1020 (DST-MOT) Errors during tuning, device detection fails in a while.
o VP-1030 (DST-CI) Tuning sometimes fails after CI commands.
o VP-2031 (DCT-CI) Tuning problems
The timeout happens before the actual timeout occured in the MCU
on the board, and hence the problems.

o Changed the custom wait queue to wait_event_interruptible_timeout()

o Fixed the wait queue timeout problem

- This problem was visible as many
* Cannot tune to channels, when signal levels are very low.

This patch adds support for a new class of DAC960 controllers. It's based
on the GPLed idac320 driver from IBM for Linux 2.4.18. That driver is a
fork of the 2.4.18 version of DAC960 that adds support for this new type of
controllers (internally called "GEM Series"), that differ from other DAC960
V2 firmware controllers only in the register offsets and removes support
for all others.
This patch instead integrates support for these controllers into the DAC960
driver.
Thanks to Anders Norrbring for pointing me to the idac320 driver and
testing this patch.
No Signed-Off: line because all code is either copy & pasted from IBM's
idac320 driver or support for other controllers in the 2.6 DAC960 driver.

The premise is that domain validation is likely to trigger errors which
it wants to know about, so the only time it should be retrying them is
when it gets a unit attention (likely as the result of a previous bus or

all cases except those of unit attention. The attached fixes this to do

With 2.6.11 and 2.6.12-rc2 (and perhaps a few versions before) usb
drivers for multi-interface devices, which do

It turns out to be due to a bug in drivers/base/bus.c:driver_detach(),
that iterates over the list of attached devices with
list_for_each_safe() under an assumption that device_release_driver()
only releases the current device, while it may also call

the "combined" table.
* Replaced FTDI_8U232AM_ALT_ALT_PID with 3 PIDs for devices from
4n-galaxy.de.
* Removed redundant FTDI_RM_VID and renamed FTDI_RMCANVIEW_PID to
FTDI_RM_CANVIEW_PID.
* Added VID/PID for serial converter in Mobility Electronics EasiDock

Miscellaneous updates for EHCI.
- Mostly updates the power switching on EHCI controllers. One routine
centralizes the "power on/off all ports" logic, and the capability to
do that is reported more correctly.
- Courtesy Colin Leroy, a patch to always power up ports after resumes
which didn't keep a USB device suspended. The reset-everything logic
powers down those ports (on some hardware) so something needs to turn
them back on.
- Minor tweaks/bugfixes for the debug port support.

I have recompiled Linux kernel 2.6.11.5 documentation for me and our
university students again. The documentation could be extended for more
sources which are equipped by structured comments for recent 2.6 kernels. I
have tried to proceed with that task. I have done that more times from 2.6.0
time and it gets boring to do same changes again and again. Linux kernel
compiles after changes for i386 and ARM targets. I have added references to
some more files into kernel-api book, I have added some section names as well.
So please, check that changes do not break something and that categories are
not too much skewed.
I have changed kernel-doc to accept "fastcall" and "asmlinkage" words reserved
by kernel convention. Most of the other changes are modifications in the
comments to make kernel-doc happy, accept some parameters description and do
not bail out on errors. Changed <pid> to @pid in the description, moved some
#ifdef before comments to correct function to comments bindings, etc.
You can see result of the modified documentation build at
http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz
Some more sources are ready to be included into kernel-doc generated
documentation. Sources has been added into kernel-api for now. Some more
section names added and probably some more chaos introduced as result of quick
cleanup work.

When allocating a new VC with vgacon_init(), the font is shared across all
the VGA consoles. However, the font mask was always set to the default
value of zero in visual_init(), even if we were using 512 character fonts
at the time.
Moreover, code in vgacon.c:vga_do_font_op() didn't reset the mask if the
console driver thinks it's already in 512 character mode. This means that
to *fix* it, you'd actually have to take the console out of 512 character
mode and then set it back.
The attached sets vc_hi_font_mask in vgacon_init() for any new consoles
opened if the vgacon driver is already in 512 character mode, solving this.
This bug goes back to 2.4.18 at least, probably earlier.

tg3_restart_ints() is called to re-enable interrupts after tg3_poll()
has finished all the work. It calls tg3_cond_int() to force an interrupt
if the status block updated bit is set. The updated bit will be set if
there is a new status block update sometime during tg3_poll() and it can
be very often. The worst part is that even if all the work has been
processed, the updated bit remains set and an interrupt will be forced
unnecessarily.
The fix is to call tg3_has_work() instead to determine if new work is
posted before forcing an interrupt. The way to force an interrupt is
also changed to use "coalesce_now" instead of "SETINT". The former is
generally a safer way to force the interrupt.
Also deleted the first parameter to tg3_has_work() which is unused.

This patch fixes a bug that causes tg3_has_work() to always return 1.
rx work is determined by comparing tp->rx_rcb_ptr with the current hw
producer index. The hw producer index is modulo the ring size, but tp-
>rx_rcb_ptr is a free running counter that goes up beyond the ring size.
After the ring wraps around once, tg3_has_work() will always return 1.
The fix is to always do modulo arithmetic on tp->rx_rcb_ptr.

This is a somewhat more comprehensive fix for the problem of devices
like the newer Zaurii ... or in this case some Motorola cell phones.
To recap, the problem's root cause is that these devices aren't using
standard USB class specifications for their network links, and so far
we've had to add lots of device-specific driver entries. The vendor
fix abuses the CDC MDLM descriptors (they _could_ have conformed to
the spec, but didn't) and defines a "Belcarra firmware" pseudo-class.
This patch recognizes that pseudo-class by the GUIDs in those descriptors,
and handles the devices that just use the Zaurus framing.

The it87 and via686a hardware monitoring drivers each create a sysfs
file named "alarms" in R/W mode, while they should really create it in
read-only mode. Since we don't provide a store function for these files,
write attempts to these files will do something undefined (I guess) and
bad (I am sure). My own try resulted in a locked terminal (where I
attempted the write) and a 100% CPU load until next reboot.
As a side note, wouldn't it make sense to check, when creating sysfs
files, that readable files have a non-NULL show method, and writable
files have a non-NULL store method? I know drivers are not supposed to
do stupid things, but there is already a BUG_ON for several conditions
in sysfs_create_file, so maybe we could add two more?

- Use the pre-allocated interrupt/status request and buffer, rather
than allocating and freeing one of each every few seconds (which

I'm planning to convert it to a top-half/bottom-half design. It turns out
that to do this, the USB API has to be modified slightly since the driver
will not be able to meet one of the guarantees in the current API. This
patch changes some kerneldoc, specifying the weaker guarantee.

This patch changes the delay for the US_FL_GO_SLOW patch from 110us to 125.
Some delays need this extra delay includign Jan De Luyck's drive which spawned
the original increase from 110 to 110us. 125 is a microframe, so this delay
seems to make sense more than just be a random delay (thanks to David Brownell

This reverts a recent change to usb_set_interface(). The change worked
around a quirk in certain devices, but doing this in usbcore creates
needless regressions for other devices. More appropriate fixes won't
put such handling in usbcore.
Basically it's tricky to do a full software reset of USB device state, since
the devices don't all act the same. This adds a note to the kerneldoc for
the usb_reset_configuration() call to highlight the quirk this was working
around: endpoint data toggles not being reset.

===================================================================
This is the first of a few installments of PM API updates to match the
recent switch to "pm_message_t". This installment primarily affects
USB device drivers (for USB interfaces), and it changes the handful of
drivers which currently implement suspend methods:
- <linux/usb.h> and usbcore, signature change
- Some drivers only changed the signature, net effect this just
shuts up "sparse -Wbitwise":
* hid-core
* stir4200
- Two network drivers did that, and also grew slightly more
featureful suspend code ... they now properly shut down
their activities. (As should stir4200...)
* pegasus
* usbnet
Note that the Wake-On-Lan (WOL) support in pegasus doesn't yet work; looks
to me like it's missing a request to turn it on, vs just configuring it.
The ASIX code in usbnet also has WOL hooks that are ready to use; untested.

This has a variety of updates to the shared suspend/resume code for
PCI based USB host controllers.
- Cope with pm_message_t replacing the target system state.
This is actually a loss of functionality; PCI D1 and D2
states will no longer be used, and it's no longer knowable
that D3cold is on the way so power will be lost.
- Most importantly, some of the resume paths are reworked and
cleaned up. They're now an exact mirror of suspend paths,
and more care is taken to ensure the hardware is reactivated
before the hardware re-enables interrupts.
Plus comment and diagnostic cleanups; there are some nasty cases here
especially combined with swsusp, now they're somewhat commented.

Don't use cmd->request->nr_hw_segments as it may not be initialized

uses scsi_do_req to insert a scsi_request directly on the head of the

the number of segments will fit in the queue ring buffer, resulting in
commands that are never completed.

Fix bug in MTT allocation in mem-free mode.
I misunderstood the MTT size value returned by the firmware -- it is really
the size of a single MTT entry, since mem-free mode does not segment the MTT
as the original firmware did. This meant that our MTT addresses ended up
being off by a factor of 8. This meant that our MTT allocations might
overlap, and so we could overwrite and corrupt earlier memory regions when
writing new MTT entries.
We fix this by always using our 64-byte MTT segment size. This allows some
simplification of the code as well, since there's no reason to put the MTT
segment size in a variable -- we can always use our enum value directly.

Correct and simplify calculation of static rate. We need to round up the
quotient of (local_rate - path_rate) / path_rate. To round up we add
(path_rate - 1) to the numerator, so the quotient simplifies to (local_rate -
1) / path_rate.
No idea how I came up with the old formula.

There is a possibility that a bio will be accessed after it has been freed
on SCSI. It happens if you submit a bio with BIO_SYNC marked and the
auto-unplugging kicks the request_fn, SCSI re-enables interrupts in-between
so if the request completes between the add_request() in __make_request()
and the bio_sync() call, we could be looking at a dead bio. It's a slim
race, but it has been triggered in the Real World.
So assign bio_sync() to a local variable instead.

My previous patch that added sleep support for uninorth-agp and some AGP
"off" stuff in radeonfb and aty128fb is breaking some configs. More
specifically, it has problems with rage128 setups since the DRI code for
these in X doesn't properly re-enable AGP on wakeup or console switch
(unlike the radeon DRM).
This patch fixes the problem for pmac once for all by using a different
approach. The AGP driver "registers" special suspend/resume callbacks with
some arch code that the fbdev's can later on call to suspend and resume
AGP, making sure it's resumed back in the same state it was when suspended.
This is platform specific for now. It would be too complicated to try to
do a generic implementation of this at this point due to all sort of weird
things going on with AGP on other architectures. We'll re-work that whole
problem cleanly once we finally merge fbdev's and DRI.
In the meantime, please apply this patch which brings back some r128 based
laptops into working condition as far as system sleep is concerned.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
