Various formats had their byte ordering implemented incorrectly, and
the V4L2_PIX_FMT_UYVY is actually impossible to create, instead you
get V4L2_PIX_FMT_YVYU.
This was working before commit ad6ac45222
("add new formats support for marvell-ccic driver"). That commit broke
the original format support and the OLPC XO-1 laptop showed wrong
colors ever since (if you are crazy enough to attempt to run the latest
kernel on it, like I did).
The email addresses of the authors of that patch are no longer valid,
so without a way to reach them and ask them about their test setup
I am going with what I can test on the OLPC laptop.
If this breaks something for someone on their non-OLPC setup, then
contact the linux-media mailinglist. My suspicion however is that
that commit went in untested.

bnx2x's 'disable_tpa=1' module option is not respected properly and TPA
(transparent packet aggregation) remains enabled. Even though the
module option causes LRO to be disabled, TPA is enabled in GRO mode.
Additionally, disabling GRO via ethtool then has no effect. One can
still observe tpa_* statistics increase and large packets being received
in tcpdump.
The bug was an unintended consequence of commit aebf6244cd "bnx2x: Be

The futex-requeue benchmark can hang because of missing wakeups once the
benchmark is done, ie:

perf: couldn't wakeup all tasks (135/1024)
This bug, while perhaps suggesting missing wakeups in kernel futex code,
is merely a consequence of the crappy FUTEX_CMP_REQUEUE man page,
incorrectly mentioning that the number of requeued tasks is in fact
returned, not the wakeups.
This patch acknowledges this and updates the corresponding futex_wake

This works around a issue with qnap iscsi targets not handling large IOs
very well.
The target returns:
VPD INQUIRY: Block limits page (SBC)
Maximum compare and write length: 1 blocks
Optimal transfer length granularity: 1 blocks
Maximum transfer length: 4294967295 blocks
Optimal transfer length: 4294967295 blocks
Maximum prefetch, xdread, xdwrite transfer length: 0 blocks
Maximum unmap LBA count: 8388607
Maximum unmap block descriptor count: 1
Optimal unmap granularity: 16383
Unmap granularity alignment valid: 0
Unmap granularity alignment: 0
Maximum write same length: 0xffffffff blocks
Maximum atomic transfer length: 0
Atomic alignment: 0
Atomic transfer length granularity: 0
and it is *sometimes* able to handle at least one IO of size up to 8 MB. We
have seen in traces where it will sometimes work, but other times it
looks like it fails and it looks like it returns failures if we send
multiple large IOs sometimes. Also it looks like it can return 2 different
errors. It will sometimes send iscsi reject errors indicating out of
resources or it will send invalid cdb illegal requests check conditions.
And then when it sends iscsi rejects it does not seem to handle retries
when there are command sequence holes, so I could not just add code to
try and gracefully handle that error code.
The problem is that we do not have a good contact for the company,
so we are not able to determine under what conditions it returns
which error and why it sometimes works.
So, this patch just adds a new black list flag to set targets like this to
the old max safe sectors of 1024. The max_hw_sectors changes added in 3.19
caused this regression, so I also ccing stable.

Because of the peculiar way that md devices are created (automatically
when the device node is opened), a new device can be created and
registered immediately after the
blk_unregister_region(disk_devt(disk), disk->minors);
call in del_gendisk().
Therefore it is important that all visible artifacts of the previous
device are removed before this call. In particular, the 'bdi'.
Since:
commit c4db59d31e
Author: Christoph Hellwig <hch@lst.de>
fs: don't reassign dirty inodes to default_backing_dev_info
moved the
device_unregister(bdi->dev);
call from bdi_unregister() to bdi_destroy() it has been quite easy to
lose a race and have a new (e.g.) "md127" be created after the
blk_unregister_region() call and before bdi_destroy() is ultimately
called by the final 'put_disk', which must come after del_gendisk().
The new device finds that the bdi name is already registered in sysfs
and complains
> [ 9627.630029] WARNING: CPU: 18 PID: 3330 at fs/sysfs/dir.c:31 sysfs_warn_dup+0x5a/0x70()
> [ 9627.630032] sysfs: cannot create duplicate filename '/devices/virtual/bdi/9:127'
We can fix this by moving the bdi_destroy() call out of
blk_release_queue() (which can happen very late when a refcount
reaches zero) and into blk_cleanup_queue() - which happens exactly when the md
device driver calls it.
Then it is only necessary for md to call blk_cleanup_queue() before
del_gendisk(). As loop.c devices are also created on demand by
opening the device node, we make the same change there.

Create a cpumask that limits the affinity of all unbound workqueues.
This cpumask is controlled through a file at the root of the workqueue
sysfs directory.
It works on a lower-level than the per WQ_SYSFS workqueues cpumask files
such that the effective cpumask applied for a given unbound workqueue is
the intersection of /sys/devices/virtual/workqueue/$WORKQUEUE/cpumask and
the new /sys/devices/virtual/workqueue/cpumask file.
This patch implements the basic infrastructure and the read interface.
wq_unbound_cpumask is initially set to cpu_possible_mask.

Current apply_workqueue_attrs() includes pwqs-allocation and pwqs-installation,
so when we batch multiple apply_workqueue_attrs()s as a transaction, we can't
ensure the transaction must succeed or fail as a complete unit.
To solve this, we split apply_workqueue_attrs() into three stages.
The first stage does the preparation: allocation memory, pwqs.
The second stage does the attrs-installaion and pwqs-installation.
The third stage frees the allocated memory and (old or unused) pwqs.
As the result, batching multiple apply_workqueue_attrs()s can
succeed or fail as a complete unit:
1) batch do all the first stage for all the workqueues
2) only commit all when all the above succeed.
This patch is a preparation for the next patch ("Allow modifying low level
unbound workqueue cpumask") which will do a multiple apply_workqueue_attrs().
The patch doesn't have functionality changed except two minor adjustment:
1) free_unbound_pwq() for the error path is removed, we use the
heavier version put_pwq_unlocked() instead since the error path
is rare. this adjustment simplifies the code.
2) the memory-allocation is also moved into wq_pool_mutex.
this is needed to avoid to do the further splitting.
tj: minor updates to comments.

The polling mode of the driver is designed for transfers that run
less than 30us - it will only execute under those circumstances.
So it should run comfortably without getting interrupted by the
scheduler.
But there are situations where the raspberry pi is so overloaded
that it can take up to 80 jiffies until the polling thread gets
rescheduled - this has been observed especially under heavy
IO situations.
In such a situation we now fall back to the interrupt handler and
log the situation at debug level.

The way that the timeout code is written in the polling function
the timeout does also trigger when interrupted or rescheduled while
in the polling loop.
This patch changes the timeout from effectively 20ms (=2 jiffies) to
1 second and removes the time that the transfer really takes out of
the computation, as - per design - this is <30us and the jiffie resolution
is 10ms so that does not make any difference what so ever.

Correct this by changing the casts to use __leXX instead of uXX.

There are very few version 0 firmwares in the wild and at some point in
the future it would be nice to remove support for them from the driver,
as they require several work arounds to be present to create controls
properly.
This patch adds a depreciated warning if someone is using this file
format.

Version 2 of the firmware file format includes length fields for the
various strings associated with control creation, to reduce file size.
However this does increase the parsing complexity slightly. This patch
adds support for the revision of the file format.
This patch also adds a new naming scheme for controls created from rev 2
firmware files. This version of the file format is commonly used to
add multiple controls per algorithm per memory region and the old
control naming scheme would cause multiple controls to have the same
name in this case.. Note that the naming scheme for older firmware
versions is left intact to ensure backwards compatibility.

Revision one of the file format includes new algorithm and coefficient
blocks which provide additional information about the controls exported
by the firmware. This patch updates the processing to handle this
version of the file format. Note that whilst this version of the format
adds support for specifying a name for the control through the firmware
file this has not been used and to keep compatibility with existing
deployments no changes to the firmware control naming are made by this
patch.
