New Asus notebooks are using a WMI device similar to
the one used in Eee PCs. Since we don't want to load
eeepc-wmi module on Asus notebooks, and we want to
keep the eeepc-wmi module for backward compatibility,
this patch introduce a new module, named asus-wmi, that
will be used by eeepc-wmi and the new Asus Notebook WMI
Driver.
eeepc-wmi's input device strings (device name and phys)
are kept, but rfkill and led names are changed (s/eeepc/asus/).
This should not break anything since rfkill are used by type or
index, not by name, and the eeepc::touchpad led wasn't working
correctly before 2.6.39 anyway.

- all the integration parameters have been captured by the binding.
- the block name really uniquely identifies this hardware.
Some advocate putting SoC names everywhere in case software needs
to work around some chip-specific bug, but more precise SoC
information already exists in SVR, and board information already
exists in the top-level device tree node.
Note that sometimes the SoC name is a worse identifier than the
block version, as the block version can change between revisions
of the same SoC.
As a matter of historical reference, neither SEC versions 2.x
nor 3.x (driven by talitos) ever needed CHIP references.

The SEC4 is also known as the Cryptographic Accelerator

autofs4 - reinstate last used update on access
vfs - check non-mountpoint dentry might block in __follow_mount_rcu()
Now that inode state changes are protected by the inode->i_lock and
the inode LRU manipulations by the inode_lru_lock, we can remove the
inode_lock from prune_icache and the initial part of iput_final().
instead of using the inode_lock to protect the inode during
iput_final, use the inode->i_lock instead. This protects the inode
against new references being taken while we change the inode state
to I_FREEING, as well as preventing prune_icache from grabbing the
inode while we are manipulating it. Hence we no longer need the
inode_lock in iput_final prior to setting I_FREEING on the inode.
For prune_icache, we no longer need the inode_lock to protect the
LRU list, and the inodes themselves are protected against freeing
races by the inode->i_lock. Hence we can lift the inode_lock from
prune_icache as well.

ADFS (FileCore) storage complies with the RISC OS filetype specification
(12 bits of file type information is stored in the file load address,
rather than using a file extension). The existing driver largely ignores
this information and does not present it to the end user.
It is desirable that stored filetypes be made visible to the end user to
facilitate a precise copy of data and metadata from a hard disc (or image
thereof) into a RISC OS emulator (such as RPCEmu) or to a network share
which can be accessed by real Acorn systems.
This patch implements a per-mount filetype suffix option (use -o
ftsuffix=1) to present any filetype as a ,xyz hexadecimal suffix on each
file. This type suffix is compatible with that used by RISC OS systems
that access network servers using NFS client software and by RPCemu's host
filing system.

On some architectures, the boot process involves de-registering the boot
console (early boot), initialize drivers and then re-register the console.
This mechanism introduces a window in which no printk can happen on the
console and messages are buffered and then printed once the new console is
available.
If a kernel crashes during this window, all it's left on the boot console
is "console [foo] enabled, bootconsole disabled" making debug of the crash
rather 'interesting'.
By adding "keep_bootcon" option, do not unregister the boot console, that
will allow to printk everything that is happening up to the crash.
The option is clearly meant only for debugging purposes as it introduces
lots of duplicated info printed on console, but will make bug report from
users easier as it doesn't require a kernel build just to figure out where
we crash.

When a cpu is considered stuck, instead of limping along and just printing
a warning, it is sometimes preferred to just panic, let kdump capture the
vmcore and reboot. This gets the machine back into a stable state quickly
while saving the info that got it into a stuck state to begin with.
Add a Kconfig option to allow users to set the hardlockup to panic
by default. Also add in a 'nmi_watchdog=nopanic' to override this.

Add a userspace API to get, set and enumerate the media format on a
subdev pad.
The format at the output of a subdev usually depends on the format at
its input(s). The try format operation is thus not suitable for probing
format at individual pads, as it can't modify the device state and thus
can't remember the format tried at the input to compute the output
format.
To fix the problem, pass an extra argument to the get/set format
operations to select the 'try' or 'active' format.
The try format is used when probing the subdev. Setting the try format
must not change the device configuration but can store data for later
reuse. Data storage is provided at the file-handle level so applications
probing the subdev concurently won't interfere with each other.
The active format is used when configuring the subdev. It's identical to
the format handled by the usual get/set operations.

Drivers often need to associate pipeline objects to entities, and to
take stream state into account when configuring entities and links. The
pipeline API helps drivers manage that information.
When starting streaming, drivers call media_entity_pipeline_start(). The
function marks all entities connected to the given entity through
enabled links, either directly or indirectly, as streaming. Similarly,
when stopping the stream, drivers call media_entity_pipeline_stop().
The media_entity_pipeline_start() function takes a pointer to a media
pipeline and stores it in every entity in the graph. Drivers should
embed the media_pipeline structure in higher-level pipeline structures
and can then access the pipeline through the media_entity structure.
Link configuration will fail with -EBUSY by default if either end of the
link is a streaming entity, unless the link is marked with the
MEDIA_LNK_FL_DYNAMIC flag.

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.

Some ioctl's were defined wrong on 2.6.2 and 2.6.6, using the wrong

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

SMSC SCH5627 Super I/O chips include complete hardware monitoring
capabilities. They can monitor up to 5 voltages, 4 fans and 8
temperatures.
The hardware monitoring part of the SMSC SCH5627 is accessed by talking
through an embedded microcontroller. An application note describing the
protocol for communicating with the microcontroller is available upon
request. Please mail me if you want a copy.

* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
powerpc/ptrace: Remove BUG_ON when full register set not available
powerpc: Factoring mpic cpu id fetching into a function
powerpc: Make MPIC honor the "pic-no-reset" device tree property
powerpc: Document the Open PIC device tree binding
powerpc/pci: Fix crash in PCI code on ppc64 when matching device nodes
This binding documents several properties that have been in use for quite
some time, and adds one new property 'pic-no-reset', which controls the
runtime initialization behavior of the PIC. More specifically, the presence
of 'pic-no-reset' mandates that the PIC shall not be reset during runtime
initialization and that any initialization related to interrupt sources
shall be limited to sources explicitly referenced in the device tree. This
functionality is useful in AMP systems where multiple OSes are sharing the
PIC and the reinitialization of the PIC can interfere with OSes that are
already up and running.
The interrupt specifier definition is based off of Stuart Yoder's FSL MPIC
binding.

The cgroup documentation does not specify how a process can be removed
from a particular group. This patch adds a note at the end of the
simple example about how this is done. Also, some cgroups (like
cpusets) require user input before a new group can be used. This is
noted in the patch as well.
