We traced this back to local_completions unlocking mad_agent_priv->lock
while still keeping a pointer into local_list. A later call to
list_del(&local->completion_list) would then corrupt the list.
To fix this, remove the entry from local_list after looking it up but
before releasing mad_agent_priv->lock, to prevent cancel_mads from

sbp2util_mark_command_completed takes a lock which was already taken by
sbp2scsi_complete_all_commands. This is a regression in Linux 2.6.15.
Reported by Kristian Harms at
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=187394
[ More complete commentary, as response to questions by Andrew: ]
> This changes the call environment for all implementations of
> ->Current_done(). Are they all safe to call under this lock?
Short answer: Yes, trust me. ;-) Long answer:
The done() callbacks are passed on to sbp2 from the SCSI stack along
with each SCSI command via the queuecommand hook. The done() callback
is safe to call in atomic context. So does
Documentation/scsi/scsi_mid_low_api.txt say, and many if not all SCSI
low-level handlers rely on this fact. So whatever this callback does,
it is "self-contained" and it won't conflict with sbp2's internal ORB
list handling. In particular, it won't race with the
sbp2_command_orb_lock.
Moreover, sbp2 already calls the done() handler with
sbp2_command_orb_lock taken in sbp2scsi_complete_all_commands(). I
admit this is ultimately no proof of correctness, especially since this
portion of code introduced the spinlock recursion in the first place and
we didn't realize it since this code's submission before 2.6.15 until
now. (I have learned a lesson from this.)
I stress-tested my patch on x86 uniprocessor with a preemptible SMP
kernel (alas I have no SMP machine yet) and made sure that all code
paths which involve the sbp2_command_orb_lock were gone through multiple
times.

Patch from Pavel Pisa
This patch adds support of i.MX/MX1 SD/MMC controller.
It has been significantly redesigned from the original Sascha Hauer's
version to support scatter-gather DMA, to conform to latest Pierre Ossman's
and Russell King's MMC-SD Linux 2.6.x infrastructure.
The handling of all events has been moved to the softirq context
and is designed with no busy-looping in mind. Unfortunately
some controller bugs has to be overcome by limited looping
about 2-20 usec but these are observed only for initial card
recognition phase.
There are still some missing/missed IRQs problems under heavy load.
Help of somebody with access to the full SDHC design information
is probably necessary.
Regenerated against 2.6.16-git-060402 to solve clash with other patches.

Unfortunately on the budget-av board, the CAM reset line is tied to the
frontend reset line, so resetting the CAM also zaps the frontend. This
breaks the tda1004x at least, and causes it to fail to tune until the
budget-av module is reloaded. This patch adds an exported function to dvb_frontend
that allows a card to forcibly reinitialise a frontend. The budget-av now
does this on CAM reset, which corrects this problem.

It should be V4L2_TUNER_MODE_LANG1_LANG2. What the code does is check if
we are NTSC and a SAP channel is available. If so, then the msp3400
should switch to standard 0x21 if the user wants to hear the SAP
channel, which is for audio modes LANG2 (aka SAP) and LANG1_LANG2
(bilingual).
In the msp3400 driver STEREO is abused for bilingual in PAL. Bilingual
never worked with NTSC in the past and I decided that I'd better not

but unfortunately some I2C implementations can't transfer data in such

around 60 bytes, due to the encapsulation there of I2C traffic into

EEPROM support, interrupt handling, statistics gathering, and write
combining management for x86_64.
A note regarding i2c: The Atmel EEPROM hardware we use looks like an
i2c device electrically, but is not i2c compliant at all from a
functional perspective. We tried using the kernel's i2c support to
talk to it, but failed.
Normal i2c devices have a single 7-bit or 10-bit i2c address that they
respond to. Valid 7-bit addresses range from 0x03 to 0x77. Addresses
0x00 to 0x02 and 0x78 to 0x7F are special reserved addresses
(e.g. 0x00 is the "general call" address.) The Atmel device, on the
other hand, responds to ALL addresses. It's designed to be the only
device on a given i2c bus. A given i2c device address corresponds to
the memory address within the i2c device itself.
At least one reason why the linux core i2c stuff won't work for this
is that it prohibits access to reserved addresses like 0x00, which are
really valid addresses on the Atmel devices.

The monochrome->color expansion routine that handles bitmaps which have

This is caused by a bogus bit test in slow_imageblit().
Fix.
This patch may deserve to go to the stable tree. The code has already been
well tested in little-endian machines. It's only in big-endian where there is
uncertainty and Herbert confirmed that this is the correct way to go.
It should not introduce regressions.

Updates to the HP Jornada 680 Backlight driver:
- Correct the suspend/resume functions so the driver compiles
(SUSPEND_POWER_DOWN/RESUME_POWER_ON no longer exist).
- Convert the driver to match the recent platform device changes.
- Replace the unsafe static struct platform_device with dynamic allocation.
- Convert the driver to the new backlight code.
This has not been tested on a device due to lack of hardware but wouldn't

Backlight class attributes are currently easy to implement incorrectly.
Moving certain handling into the backlight core prevents this whilst at the
same time makes the drivers simpler and consistent. The following changes are
included:
The brightness attribute only sets and reads the brightness variable in the
backlight_properties structure.
The power attribute only sets and reads the power variable in the
backlight_properties structure.
Any framebuffer blanking events change a variable fb_blank in the
backlight_properties structure.
The backlight driver has only two functions to implement. One function is
called when any of the above properties change (to update the backlight
brightness), the second is called to return the current backlight brightness
value. A new attribute "actual_brightness" is added to return this brightness
as determined by the driver having combined all the above factors (and any
driver/device specific factors).
Additionally, the backlight core takes care of checking the maximum brightness
is not exceeded and of turning off the backlight before device removal.
The corgi backlight driver is updated to reflect these changes.
