The Allwinner A10 has an ethernet controller that seem to be developped
internally by them.
The exact feature set of this controller is unknown, since there is no
public documentation for this IP, and this driver is mostly the one
published by Allwinner that has been heavily cleaned up.

This adds device tree parsing support for the shared driver of mv643xx_eth.
As the bindings are slightly different from current PPC bindings new binding
documentation is also added. Following PPC-style device setup, the shared
driver now also adds port platform_devices and sets up port platform_data.

As Stephen proposed:
Since bonding supports configuration via iproute (netlink) and sysfs, I think
it is time to purge the old ifenslave code out of Documentation/networking
and update the documentation.

There is no point. We would just squeeze the guest to put more and
more pages in the swap disk without any purpose.
The only time it makes sense to use the selfballooning and shrinking
is when frontswap is being utilized.

If tmem is built-in or a module, the user has the option on
the command line to influence it by doing: tmem.<some option>
instead of having a variety of "nocleancache", and
"nofrontswap". The others: "noselfballooning" and "selfballooning";
and "noselfshrink" are in a different driver xen-selfballoon.c
and the patches:
xen/tmem: Remove the usage of 'noselfshrink' and use 'tmem.selfshrink' bool instead.
xen/tmem: Remove the usage of 'noselfballoon','selfballoon' and use 'tmem.selfballon' bool instead.
remove them.
Also add documentation.

The Linux kernel uses a number of per-CPU kthreads, any of which might
contribute to OS jitter at any time. The usual approach to normal
kthreads, namely to bind them to a "housekeeping" CPU, does not work
with these kthreads because they cannot operate correctly if moved to
some other CPU. This commit therefore lists ways of controlling OS
jitter from the Linux kernel's per-CPU kthreads. It also lists some
ways of diagnosing excessive jitter.

Pull MIPS updates from Ralf Baechle:
- More work on DT support for various platforms
- Various fixes that were to late to make it straight into 3.9
- Improved platform support, in particular the Netlogic XLR and
BCM63xx, and the SEAD3 and Malta eval boards.
- Support for several Ralink SOC families.
- Complete support for the microMIPS ASE which basically reencodes the
existing MIPS32/MIPS64 ISA to use non-constant size instructions.
- Some fallout from LTO work which remove old cruft and will generally
make the MIPS kernel easier to maintain and resistant to compiler
optimization, even in absence of LTO.
- KVM support. While MIPS has announced hardware virtualization
extensions this KVM extension uses trap and emulate mode for
virtualization of MIPS32. More KVM work to add support for VZ
hardware virtualizaiton extensions and MIPS64 will probably already
be merged for 3.11.
Most of this has been sitting in -next for a long time. All defconfigs
have been build or run time tested except three for which fixes are being
sent by other maintainers.

Pull ARM SoC fixes and straggler patches from Olof Johansson:
"A collection of fixes for fall out from 3.10 merge window, some build
fixes and warning cleanups and a small handful of patches that were
small and contained and made sense to still include in 3.10 (some of
these have also been in -next since the merge window opened).
Largest continous series is for OMAP, but there's a handful for other
platforms.
For i.MX, one of the patches are framebuffer fixups due to fallout
during the merge window, and the other removes some stale and broken
code."

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren:
Omap fixes for things that were discovered during the merge window:
- Few GPMC fixes and binding doc updates noted after sending
pull requests for the GPMC branch.
- Board fixes for beagle usb host and rx51 spi probe order
- SoC fixes dt earlyprintk, omap1 dma and omap2+ id.c error
handling fixes
Then few minor things that are not strictly fixes but are good
to get out of the way:
- Add missing legacy mux registers for am/dm73x gpio
- Add detection for am33xx pg2.1 silicon
- Enable twl4030 audio modules in defconfig

The GPMC timing properties for device-tree have been updated
by adding a "-ns" or "-ps" suffix to indicate the units of
time the property represents. Therefore, update the timing
property names for TI GPMC NAND example.

Pull btrfs update from Chris Mason:
"These are mostly fixes. The biggest exceptions are Josef's skinny
extents and Jan Schmidt's code to rebuild our quota indexes if they
get out of sync (or you enable quotas on an existing filesystem).
The skinny extents are off by default because they are a new variation
on the extent allocation tree format. btrfstune -x enables them, and
the new format makes the extent allocation tree about 30% smaller.
I rebased this a few days ago to rework Dave Sterba's crc checks on
the super block, but almost all of these go back to rc6, since I
though 3.9 was due any minute.
The biggest missing fix is the tracepoint bug that was hit late in
3.9. I ran into problems with that in overnight testing and I'm still
tracking it down. I'll definitely have that fixed for rc2."

GENERIC_GPIO has been made equivalent to GPIOLIB in architecture code
and all driver code has been switch to depend on GPIOLIB. It is thus

There is a new generic API to get a DMA channel for a slave device (commit
9a6cecc8 "dmaengine: add helper function to request a slave DMA channel"). In
similar fashion to the DT case (commit aa3da644 "of: Add generic device tree
DMA helpers") we introduce helpers to the DMAC drivers which are enumerated by
ACPI.
The proposed extension provides the following API calls:
acpi_dma_controller_register(), devm_acpi_dma_controller_register()
acpi_dma_controller_free(), devm_acpi_dma_controller_free()
acpi_dma_simple_xlate()
acpi_dma_request_slave_chan_by_index()
acpi_dma_request_slave_chan_by_name()
The first two should be used, for example, at probe() and remove() of the
corresponding DMAC driver. At the register stage the DMAC driver supplies a
custom xlate() function to translate a struct dma_spec into struct dma_chan.
Accordingly to the ACPI Fixed DMA resource specification the only two pieces of
information the slave device has are the channel id and the request line (slave
id). Those two are represented by struct dma_spec. The
acpi_dma_request_slave_chan_by_index() provides access to the specifix FixedDMA
resource by its index. Whereas dma_request_slave_channel() takes a string
parameter to identify the DMA resources required by the slave device. To make a
slave device driver work with both DeviceTree and ACPI enumeration a simple
convention is established: "tx" corresponds to the index 0 and "rx" to the
index 1. In case of robust configuration the slave device driver unfortunately
needs to call acpi_dma_request_slave_chan_by_index() directly.
Additionally the patch provides "managed" version of the register/free pair
i.e. devm_acpi_dma_controller_register() and devm_acpi_dma_controller_free().
Usually, the driver uses only devm_acpi_dma_controller_register().

Comparison between buffers is stored to the dedicated structure.
Note that the verify result is now accessible only via file 'results' in the
debugfs.

The patch provides a storage for the test results in the linked list. The
gathered data could be used after test is done.
The new file 'results' represents gathered data of the in progress test. The
messages collected are printed to the kernel log as well.
Example of output:
% cat /sys/kernel/debug/dmatest/results
dma0chan0-copy0: #1: No errors with src_off=0x7bf dst_off=0x8ad len=0x3fea (0)
The message format is unified across the different types of errors. A number in
the parens represents additional information, e.g. error code, error counter,
or status.
Note that the buffer comparison is done in the old way, i.e. data is not
collected and just printed out.
