a09820043c dw_dmac: autoconfigure data_width or get it via platform data
Not all of the controllers support the 64 bit data width. Make it configurable
via platform data. The driver will try to get a value from the component
parameters, otherwise it will use the platform data.

4a63a8b3e8 dw_dmac: autoconfigure block_size or use platform data
The maximum block size is a configurable parameter for the chip. So, driver
will try to get it from the encoded component parameters. Otherwise it will
come from the platform data.

482c67ea7b dw_dmac: get number of channels from hardware if possible
In case the controller has the encoded parameters feature enabled the driver
will use it to get the number of channels. In the future it will be used for
the other important parameters as well.

2a9fe9ae3a dw_dmac: fill optional encoded parameters in register structure
There is a block of the registers that are optional. However, if enabled they
contain useful information about the controller hardware configuration. We will
use this piece of data to autoconfigure the driver.

5e97fa9149 mxs/dma: Enlarge the CCW descriptor area to 4 pages
In case of a large SPI flash, the amount of DMA descriptors
available to the DMA driver is not large enough anymore. For
example 8MB SPI flash now needs 129 descriptors to be transfered
in one long read. There are currently 53 descriptors available in
one PAGE_SIZE-big block. Enlarge the allocated descriptor area to
four PAGE_SIZE blocks to fulfill such requirements.

8fccc5bfd7 dw_dmac: utilize slave_id to pass request line
There is slave_id field in the generic slave config structure that is dedicated
for the uniq slave number. In our case we have the request lines wired to the
certain hardware. Therefore the number of the request line is uniq and could be
used as slave_id. It allows us in some cases to drop out the usage of the
custom slave config structure.

c8acd6aa6b dmaengine: mmp-pdma support
1. virtual channel vs. physical channel
Virtual channel is managed by dmaengine
Physical channel handling resource, such as irq
Physical channel is alloced dynamically as descending priority,
freed immediately when irq done.
The availble highest priority physically channel will alwayes be alloced

Issue pending list -> alloc highest dma physically channel available -> dma done -> free physically channel

2. list: running list & pending list
submit: desc list -> pending list
issue_pending_list: if (IDLE) pending list -> running list; free pending list (RUN)
irq: free running list (IDLE)
     check pendlist -> pending list -> running list; free pending list (RUN)

3. irq:
Each list generate one irq, calling callback
One list may contain several desc chain, in such case, make sure only the last desc list generate irq.

4. async
Submit will add desc chain to pending list, which can be multi-called
If multi desc chain is submitted, only the last desc would generate irq -> call back
If IDLE, issue_pending_list start pending_list, transforming pendlist to running list
If RUN, irq will start pending list

5. test
5.1 pxa3xx_nand on pxa910
5.2 insmod dmatest.ko (threads_per_chan=y)
By default drivers/dma/dmatest.c test every channel and test memcpy with 1 threads per channel

94d3901c11 drivers/dma/sirf-dma.c: fix usage of devm functions
Fix some problems with the use of devm_ functions.

devm_kzalloc: devm_kfree is not needed

devm_ioremap: iounmap should not be used, no free is needed

devm_request_irq: the devm_free_irq is followed by irq_dispose_mapping.  I
don't know if it is safe to move the freeing of the irq in this case, so I
have just un-devm'd this function, since the implicit freeing is never
taken advantage of.

In the original code failure of of_address_to_resource jumped to free_mem,
but should have jumped to irq_dispose, since irq_of_parse_and_map has
completed at this point.

In the original code unmap_mem was after irq_dispose, but it should have
been before, again since irq_of_parse_and_map has completed at this point.

One of these problems was found using the following semantic match:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
expression x;
@@

*x = devm_ioremap(...)
...
iounmap(x);

bfdf85dfce ARM: arm-soc: cpuidle enablement for OMAP
Coupled cpuidle was meant to merge for 3.5 through Len Brown's tree, but
 didn't go in because the pull request ended up rejected. So it just got
 merged, and we got this staged branch that enables the coupled cpuidle
 code on OMAP.
 
 With a stable git workflow from the other maintainer we could have staged
 this earlier, but that wasn't the case so we have had to merge it late.
 
 The alternative is to hold it off until 3.7 but given that the code is
 well-isolated to OMAP and they are eager to see it go in, I didn't push
 back hard in that direction.

8783b6e2b2 mm: remove node_start_pfn checking in new WARN_ON for now

88fdf75d1b ("mm: warn if pg_data_t isn't initialized with zero")
triggers for him, and it is the node_start_pfn field that has already
been initialized once.

The call trace looks like this:

    start_kernel ->
    setup_arch ->
    paging_init ->

5ef50c3bec ceph: simplify+fix atomic_open
The initial ->atomic_open op was carried over from the old intent code,
which was incomplete and didn't really work.  Replace it with a fresh
method.  In particular:

 * always attempt to do an atomic open+lookup, both for the create case
   and for lookups of existing files.
 * fix symlink handling by returning 1 to the VFS so that we can follow
   the link to its destination. This fixes a longstanding ceph bug (#2392).

Pull ARM DMA engine updates from Russell King:
 "This looks scary at first glance, but what it is is:
   - a rework of the sa11x0 DMA engine driver merged during the previous
     cycle, to extract a common set of helper functions for DMA engine
     implementations.
   - conversion of amba-pl08x.c to use these helper functions.
   - addition of OMAP DMA engine driver (using these helper functions),
     and conversion of some of the OMAP DMA users to use DMA engine.

  Nothing in the helper functions is ARM specific, so I hope that other
  implementations can consolidate some of their code by making use of
  these helpers.

  This has been sitting in linux-next most of the merge cycle, and has
  been tested by several OMAP folk.  I've tested it on sa11x0 platforms,
  and given it my best shot on my broken platforms which have the
  amba-pl08x controller.

  The last point is the addition to feature-removal-schedule.txt, which
  will have a merge conflict.  Between myself and TI, we're planning to
  remove the old TI DMA implementation next year."
