2011-03-22[media] media: Entity use countLaurent Pinchart
Due to the wide differences between drivers regarding power management needs, the media controller does not implement power management. However, the media_entity structure includes a use_count field that media drivers can use to track the number of users of every entity for power management needs. The use_count field is owned by media drivers and must not be touched by entity drivers. Access to the field must be protected by the media device graph_mutex lock.

2011-03-22[media] media: Entity graph traversalSakari Ailus
Add media entity graph traversal. The traversal follows enabled links by depth first. Traversing graph backwards is prevented by comparing the next possible entity in the graph with the previous one. Multiply connected graphs are thus not supported.

2011-03-22[media] media: Entities, pads and linksLaurent Pinchart
As video hardware pipelines become increasingly complex and configurable, the current hardware description through v4l2 subdevices reaches its limits. In addition to enumerating and configuring subdevices, video camera drivers need a way to discover and modify at runtime how those subdevices are connected. This is done through new elements called entities, pads and links. An entity is a basic media hardware building block. It can correspond to a large variety of logical blocks such as physical hardware devices (CMOS sensor for instance), logical hardware devices (a building block in a System-on-Chip image processing pipeline), DMA channels or physical connectors. A pad is a connection endpoint through which an entity can interact with other entities. Data (not restricted to video) produced by an entity flows from the entity's output to one or more entity inputs. Pads should not be confused with physical pins at chip boundaries. A link is a point-to-point oriented connection between two pads, either on the same entity or on different entities. Data flows from a source pad to a sink pad. Links are stored in the source entity. To make backwards graph walk faster, a copy of all links is also stored in the sink entity. The copy is known as a backlink and is only used to help graph traversal. The entity API is made of three functions: - media_entity_init() initializes an entity. The caller must provide an array of pads as well as an estimated number of links. The links array is allocated dynamically and will be reallocated if it grows beyond the initial estimate. - media_entity_cleanup() frees resources allocated for an entity. It must be called during the cleanup phase after unregistering the entity and before freeing it. - media_entity_create_link() creates a link between two entities. An entry in the link array of each entity is allocated and stores pointers to source and sink pads. When a media device is unregistered, all its entities are unregistered automatically. The code is based on Hans Verkuil <hverkuil@xs4all.nl> initial work.

2011-03-21IPVS: Use global mutex in ip_vs_app.cSimon Horman
As part of the work to make IPVS network namespace aware __ip_vs_app_mutex was replaced by a per-namespace lock, ipvs->app_mutex. ipvs->app_key is also supplied for debugging purposes. Unfortunately this implementation results in ipvs->app_key residing in non-static storage which at the very least causes a lockdep warning. This patch takes the rather heavy-handed approach of reinstating __ip_vs_app_mutex which will cover access to the ipvs->list_head of all network namespaces.

The AER error information printing support is implemented in drivers/pci/pcie/aer/aer_print.c. So some string constants, functions and macros definitions can be re-used without being exported. The original PCIe AER error information printing function is not re-used directly because the overall format is quite different. And changing the original printing format may make some original users' scripts broken.

2011-03-21ACPI, APEI, Add ERST record ID cacheHuang Ying
APEI ERST firmware interface and implementation has no multiple users in mind. For example, if there is four records in storage with ID: 1, 2, 3 and 4, if two ERST readers enumerate the records via GET_NEXT_RECORD_ID as follow, reader 1 reader 2 1 2 3 4 -1 -1 where -1 signals there is no more record ID. Reader 1 has no chance to check record 2 and 4, while reader 2 has no chance to check record 1 and 3. And any other GET_NEXT_RECORD_ID will return -1, that is, other readers will has no chance to check any record even they are not cleared by anyone. This makes raw GET_NEXT_RECORD_ID not suitable for used by multiple users. To solve the issue, an in-memory ERST record ID cache is designed and implemented. When enumerating record ID, the ID returned by GET_NEXT_RECORD_ID is added into cache in addition to be returned to caller. So other readers can check the cache to get all record ID available.

So if the SA is created by pf_key, any input packet with SA's encryption algorithm will cause panic. int xfrm_input() { ... x->repl->advance(x, seq); ... } This patch fixed it by introduce new function __xfrm_init_state().

2011-03-21[media] v4l: removal of old, obsolete ioctlsHans Verkuil
Some ioctl's were defined wrong on 2.6.2 and 2.6.6, using the wrong type of R/W arguments. They were fixed, but the old ioctl names are still there, maintained to avoid breaking binary compatibility: There's no sense on preserving those forever, as it is very doubtful that someone would try to use a such old binary with a modern kernel. Removing them will allow us to remove some magic done at the V4L ioctl handler. Note that any application compiled with a videodev2.h from 2.6.7 or later will be using the correct ioctls.

2011-03-21[media] Remove the remaining usages for T_STANDBYMauro Carvalho Chehab
tda9887 used to use the T_STANDBY type internally, while tea5761 used it to put the device to sleep. Fix the code for it to work properly with the tuner core changes and remove this flag from tuner.h. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-03-21[media] tuner-core: Better implement standby modeMauro Carvalho Chehab
In the past, T_STANDBY were used on devices with a separate radio tuner to mark a tuner that were disabled. With the time, it got newer meanings. Also, due to a bug at the logic, the driver might incorrectly return T_STANDBY to userspace. So, instead of keeping the abuse, just use a boolean for storing such information. We can't remove T_STANDBY yet, as this is used on two other drivers. A latter patch will address its usage outside tuner-core.

2011-03-21[media] Add v4l2 subdev driver for NOON010PC30L image sensorSylwester Nawrocki
Add I2C/V4L2 subdev driver for Siliconfile NOON010PC30 CIF camera. The driver implements basic functionality, i.e. CIF/QCIF/QQCIF resolution and color format selection, automatic/manual color balance control. Other functions like cropping, rotation/flip, exposure etc. can be easily implemented if needed.
