    common: dma-mapping: introduce dma_get_sgtable() function

    This patch adds dma_get_sgtable() function which is required to let
    drivers to share the buffers allocated by DMA-mapping subsystem. Right
    now the driver gets a dma address of the allocated buffer and the kernel
    virtual mapping for it. If it wants to share it with other device (= map
    into its dma address space) it usually hacks around kernel virtual
    addresses to get pointers to pages or assumes that both devices share
    the DMA address space. Both solutions are just hacks for the special
    cases, which should be avoided in the final version of buffer sharing.

    To solve this issue in a generic way, a new call to DMA mapping has been
    introduced - dma_get_sgtable(). It allocates a scatter-list which
    describes the allocated buffer and lets the driver(s) to use it with
    other device(s) by calling dma_map_sg() on it.

    This patch provides a generic implementation based on virt_to_page()
    call. Architectures which require more sophisticated translation might
    provide their own get_sgtable() methods.

compat: add helpers to aid backport of generic DMA changes for v4l

Commit c60520fa needs to be reverted for older kernels because
although we can backport some large changes to DMA that
ended up extending some core dma data structures, for

changes required add a helper that lets us call what we used

We're only adding this for >= 3.2 as this is required only
for media which are also only supporting on >= 3.2.

    lib: devres: Introduce devm_ioremap_resource()

    The devm_request_and_ioremap() function is very useful and helps avoid a
    whole lot of boilerplate. However, one issue that keeps popping up is
    its lack of a specific error code to determine which of the steps that
    it performs failed. Furthermore, while the function gives an example and
    suggests what error code to return on failure, a wide variety of error
    codes are used throughout the tree.

    In an attempt to fix these problems, this patch adds a new function that
    drivers can transition to. The devm_ioremap_resource() returns a pointer
    to the remapped I/O memory on success or an ERR_PTR() encoded error code
    on failure. Callers can check for failure using IS_ERR() and determine
    its cause by extracting the error code using PTR_ERR().

    devm_request_and_ioremap() is implemented as a wrapper around the new
    API and return NULL on failure as before. This ensures that backwards
    compatibility is maintained until all users have been converted to the
    new API, at which point the old devm_request_and_ioremap() function
    should be removed.

    A semantic patch is included which can be used to convert from the old
    devm_request_and_ioremap() API to the new devm_ioremap_resource() API.
    Some non-trivial cases may require manual intervention, though.

that from our port given that we do this port

compat: backport dma-buf

dma-buf was added via commit d15bd7ee on v3.3 but completed
in a more sound fassion in later kernels, you should preferably
be at v3.5 a least, so we take the latest dma-buf implementation
and port it for usage on kernels [3.0-3.4].

This is implemented as a non modular solution upstream but
we can carry the implementation into our compat module.

Note that although commit f23513e8d was added on v2.6.23
that allowed the kernel to call get_unused_fd_flags(flags)
for O_CLOEXEC setting, this routine was not exported until
v3.7. dma-buf makes use of it, and since our backported
dma-buf implementation is modular it means we have to work
around the lack of get_unused_fd_flags() exported symbol
on older kernels. Due to the security concerns noted by
Ulrich on f23513e8 we need to ensure the operatin is
atomic so we fix this on our port of dma-buf for older
kernels by adding our own dma_buf_fd_set_flag() to be called
when dma_buf_fd() is used. This implementation is available
for usage on kernels >= 3.0. We disable it for v3.5 as
we're happy with that implementation.

    dma-buf: Introduce dma buffer sharing mechanism

    This is the first step in defining a dma buffer sharing mechanism.

    A new buffer object dma_buf is added, with operations and API to allow easy
    sharing of this buffer object across devices.

    The framework allows:
    - creation of a buffer object, its association with a file pointer, and
       associated allocator-defined operations on that buffer. This operation is
       called the 'export' operation.
    - different devices to 'attach' themselves to this exported buffer object, to
      facilitate backing storage negotiation, using dma_buf_attach() API.
    - the exported buffer object to be shared with the other entity by asking for
       its 'file-descriptor (fd)', and sharing the fd across.
    - a received fd to get the buffer object back, where it can be accessed using
       the associated exporter-defined operations.
    - the exporter and user to share the scatterlist associated with this buffer
       object using map_dma_buf and unmap_dma_buf operations.

    Atleast one 'attach()' call is required to be made prior to calling the
    map_dma_buf() operation.

    Couple of building blocks in map_dma_buf() are added to ease introduction
    of sync'ing across exporter and users, and late allocation by the exporter.

    For this first version, this framework will work with certain conditions:
    - *ONLY* exporter will be allowed to mmap to userspace (outside of this
       framework - mmap is not a buffer object operation),
    - currently, *ONLY* users that do not need CPU access to the buffer are
       allowed.

    More details are there in the documentation patch.

    This is based on design suggestions from many people at the mini-summits[1],
    most notably from Arnd Bergmann <arnd@arndb.de>, Rob Clark <rob@ti.com> and
    Daniel Vetter <daniel@ffwll.ch>.

    The implementation is inspired from proof-of-concept patch-set from
    Tomasz Stanislawski <t.stanislaws@samsung.com>, who demonstrated buffer sharing
    between two v4l2 devices. [2]

git tracker: handle temporary failures better

If there are multiple commits in the source kernel, one
of which causes backporting failures (ie. patches don't
apply), and a subsequent one fixes it, the output is
