2009-12-16V4L/DVB (13659): soc-camera: convert to the new mediabus APIGuennadi Liakhovetski
Convert soc-camera core and all soc-camera drivers to the new mediabus API. This also takes soc-camera client drivers one step closer to also be usable with generic v4l2-subdev host drivers.

2009-12-16V4L/DVB (13658): v4l: add a media-bus API for configuring v4l2 subdev pixel ↵Guennadi Liakhovetski
and frame formats Video subdevices, like cameras, decoders, connect to video bridges over specialised busses. Data is being transferred over these busses in various formats, which only loosely correspond to fourcc codes, describing how video data is stored in RAM. This is not a one-to-one correspondence, therefore we cannot use fourcc codes to configure subdevice output data formats. This patch adds codes for several such on-the-bus formats and an API, similar to the familiar .s_fmt(), .g_fmt(), .try_fmt(), .enum_fmt() API for configuring those codes. After all users of the old API in struct v4l2_subdev_video_ops are converted, it will be removed. Also add helper routines to support generic pass-through mode for the soc-camera framework. create mode 100644 drivers/media/video/soc_mediabus.c create mode 100644 include/media/soc_mediabus.h create mode 100644 include/media/v4l2-mediabus.h Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Acked-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2009-12-16HWPOISON: Add soft page offline supportAndi Kleen
This is a simpler, gentler variant of memory_failure() for soft page offlining controlled from user space. It doesn't kill anything, just tries to invalidate and if that doesn't work migrate the page away. This is useful for predictive failure analysis, where a page has a high rate of corrected errors, but hasn't gone bad yet. Instead it can be offlined early and avoided. The offlining is controlled from sysfs, including a new generic entry point for hard page offlining for symmetry too. We use the page isolate facility to prevent re-allocation race. Normally this is only used by memory hotplug. To avoid races with memory allocation I am using lock_system_sleep(). This avoids the situation where memory hotplug is about to isolate a page range and then hwpoison undoes that work. This is a big hammer currently, but the simplest solution currently. When the page is not free or LRU we try to free pages from slab and other caches. The slab freeing is currently quite dumb and does not try to focus on the specific slab cache which might own the page. This could be potentially improved later. Thanks to Fengguang Wu and Haicheng Li for some fixes. [Added fix from Andrew Morton to adapt to new migrate_pages prototype] Signed-off-by: Andi Kleen <ak@linux.intel.com>

Instead of adding a (struct dock_station **) to our dock device's platform data, we can add the (struct dock_station *) directly. This change saves us some ugly casting and improves readability. The cost of making this change is an extra 290 bytes of stack usage, but this is an infrequently called code-path and unlikely to cause the kernel to blow up.

2009-12-15ixgbe: allow tx of pre-formatted vlan tagged packetsGurucharan Shetty
When the 82598 is fed 802.1q packets, it chokes with an error of the form: ixgbe: eth0: ixgbe_tx_csum: partial checksum but proto=81! As the logic there was not smart enough to look into the vlan header to pick out the encapsulated protocol. There are times when we'd like to send these packets out without having to configure a vlan on the interface. Here we check for the vlan tag and allow the packet to go out with the correct hardware checksum. This patch is a clone of a previously submitted patch by Arthur Jones <ajones@riverbed.com> for igb (Commit - fa4a7ef36ec834fee1719636b30d2f28f4cb0166).

Modified patch with Dave's comments to replace mdelay with proper msleep. Fix 82598 copper link issue, where the phy prematurely indicates link before it is ready to process packets. The new function looks for phy link and indicates that, when it is available. If phy is not ready within few seconds of MAC indicating link, the function will return failure which translates to link down indication.

2009-12-16drm/nouveau: prevent all channel creation if accel not availableBen Skeggs
Previously, if there was no firmware available, the DRM would just disable channel creation from userspace, but still use a single channel for its own purposes. With a bit of care it should actually be possible to do this, due to the DRM's very limited use of the engine. It currently doesn't work correctly however, resulting in corrupted fbcon and hangs on a number of cards. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2009-12-16drm/nv40: implement ctxprog/state generationBen Skeggs
The context programs are *very* simple compared to the ones used by the binary driver. There's notes in nv40_grctx.c explaining most of the things we don't implement. If we discover if/why any of it is required further down the track, we'll handle it then. The PGRAPH state generated for each chipset should match what NVIDIA do almost exactly (there's a couple of exceptions). If someone has a lot of time on their hands, they could figure out the mapping of object/method to PGRAPH register and demagic the initial state a little, it's not terribly important however. At time of commit, confirmed to be working at least well enough for accelerated X (and where tested, for 3D apps) on NV40, NV43, NV44, NV46, NV49, NV4A, NV4B and NV4E. A module option has been added to force the use of external firmware blobs if it becomes required. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
