Pull kdump fixes from Peter Anvin:
"The kexec/kdump people have found several problems with the support
for loading over 4 GiB that was introduced in this merge cycle. This
is partly due to a number of design problems inherent in the way the
various pieces of kdump fit together (it is pretty horrifically manual
in many places.)
After a *lot* of iterations this is the patchset that was agreed upon,
but of course it is now very late in the cycle. However, because it
changes both the syntax and semantics of the crashkernel option, it
would be desirable to avoid a stable release with the broken
interfaces."
I'm not happy with the timing, since originally the plan was to release
the final 3.9 tomorrow. But apparently I'm doing an -rc8 instead...

Pull x86 fixes from Peter Anvin:
"Three groups of fixes:
1. Make sure we don't execute the early microcode patching if family
< 6, since it would touch MSRs which don't exist on those
families, causing crashes.
2. The Xen partial emulation of HyperV can be dealt with more
gracefully than just disabling the driver.
3. More EFI variable space magic. In particular, variables hidden
from runtime code need to be taken into account too."

Multiple parts of next/drivers are prerequisites for the final
exynos multiplatform changes, so let's pull in the entire branch.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
This is a series originally prepared for inclusion in 3.9, which did
not work out because of dependencies on the dmaengine driver. All the
changes for the dmaengine code are merged in 3.9 now, so we can finally
do the switchover and remove the now unnecessary dma definitions for
spear13xx from the platform code.
The dma platform_data actually made up the majority of the spear13xx
platform code overall, so moving that into device tree files makes the
code substantially smaller.
* spear/dwdma:
ata: arasan: remove the need for platform_data
ARM: SPEAr13xx: Pass generic DW DMAC platform data from DT
serial: pl011: use generic DMA slave configuration if possible
spi: pl022: use generic DMA slave configuration if possible
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
This adds a complete DT binding for the arasan device driver. There is
currently only one user, which is the spear13xx platform, so we don't
actually have to parse all the properties until another user comes in,
but this does use the generic DMA binding to find the DMA channel.
The patch is untested so far and is part of a series to convert
the spear platform over to use the generic DMA binding, so it
should stay with the rest of the series.

We need full dynticks CPU to also be RCU nocb so
that we don't have to keep the tick to handle RCU
callbacks.
Make sure the range passed to nohz_full= boot
parameter is a subset of rcu_nocbs=
The CPUs that fail to meet this requirement will be
excluded from the nohz_full range. This is checked
early in boot time, before any CPU has the opportunity
to stop its tick.

The timekeeping job must be able to run early on boot
because there may be some pre-SMP (and thus pre-initcalls )
components that rely on it. The IO-APIC is one such users
as it tests the timer health by watching jiffies progression.
Given that it happens before we know the initial online
set, we can't rely on it to select a timekeeper. We need
one before SMP time otherwise we simply crash on boot.
To fix this and keep things simple for now, force the boot CPU
outside of the full dynticks range in any case and do this early
on kernel parameter parsing time.
We might want a trickier solution later, expecially for aSMP
architectures that need to assign housekeeping tasks to arbitrary
low power CPUs.
But it's still first pass KISS time for now.

The main additional change here is Lars-Peter's DMA work plus the

factor a large chunk of code out of the drivers for the platforms using
dmaengine, greatly simplifying development.

This adds new debug feature information so that the DAWR can be
identified by userspace tools like GDB.
Unfortunately the DAWR doesn't sit nicely into the current description
that ptrace provides to userspace via struct ppc_debug_info. It doesn't
allow for specifying that only some ranges are possible or even the end
alignment constraints (DAWR only allows 512 byte wide ranges which can't
cross a 512 byte boundary).
After talking to Edjunior Machado (GDB ppc developer), it was decided
this was the best approach. Just mark it as debug feature DAWR and
tools like GDB can internally decide the constraints.

Chao said that kdump does does work well on his system on 3.8
without extra parameter, even iommu does not work with kdump.
And now have to append crashkernel_low=Y in first kernel to make
kdump work.
We have now modified crashkernel=X to allocate memory beyong 4G (if
available) and do not allocate low range for crashkernel if the user
does not specify that with crashkernel_low=Y. This causes regression
if iommu is not enabled. Without iommu, swiotlb needs to be setup in
first 4G and there is no low memory available to second kernel.
Set crashkernel_low automatically if the user does not specify that.
For system that does support IOMMU with kdump properly, user could
specify crashkernel_low=0 to save that 72M low ram.

This has a nasty set of conflicts with the exynos MCT code, which was
moved in a separate branch, and then fixed up when merged in, but still
conflicts a bit here. It should have been sorted out by this merge though.
Using this parameter one can disable the storage_size/2 check if
he is really sure that the UEFI does sane gc and fulfills the spec.
This parameter is useful if a devices uses more than 50% of the

The i2c-arb-gpio-challenge driver implements an I2C arbitration scheme
where masters need to claim the bus with a GPIO before they can start
a transaction. This should generally only be used when standard I2C
multimaster isn't appropriate for some reason (errata/bugs).
This driver is based on code that Simon Glass added to the i2c-s3c2410
driver in the Chrome OS kernel 3.4 tree. The current incarnation as a
mux driver is as suggested by Grant Likely. See
<https://patchwork.kernel.org/patch/1877311/> for some history.

"Extended nohz" was used as a naming base for the full dynticks
API and Kconfig symbols. It reflects the fact the system tries
to stop the tick in more places than just idle.
But that "extended" name is a bit opaque and vague. Rename it to
"full" makes it clearer what the system tries to do under this
config: try to shutdown the tick anytime it can. The various
constraints that prevent that to happen shouldn't be considered
as fundamental properties of this feature but rather technical
issues that may be solved in the future.

A bunch of changes here, the most interesting one subsystem wise being
Morimoto-san's work to create snd_soc_component which doesn't do much
for now but will be pretty important going forwards:
- Add a new component object type which will form the basis of moving
to a more generic handling of SoC and off-SoC components, contributed
by Kuninori Morimoto.
- A fairly large set of cleanups for the dmaengine integration from
Lars-Peter Clausen, starting to move towards being able to have a
generic driver based on the library.
- Performance optimisations to DAPM from Ryo Tsutsui.
- Support for mixer control sharing in DAPM from Stephen Warren.
- Multiplatform ARM cleanups from Arnd Bergmann.
- New CODEC drivers for AK5385 and TAS5086 from Daniel Mack.

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().

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.

Instead of doing
modprobe dmatest ...
modprobe -r dmatest
we allow user to run tests interactively.
The dmatest could be built as module or inside kernel. Let's consider those
cases.
1. When dmatest is built as a module...
After mounting debugfs and loading the module, the /sys/kernel/debug/dmatest
folder with nodes will be created. They are the same as module parameters with
addition of the 'run' node that controls run and stop phases of the test.
Note that in this case test will not run on load automatically.
Example of usage:
% echo dma0chan0 > /sys/kernel/debug/dmatest/channel
% echo 2000 > /sys/kernel/debug/dmatest/timeout
% echo 1 > /sys/kernel/debug/dmatest/iterations
% echo 1 > /sys/kernel/debug/dmatest/run
After a while you will start to get messages about current status or error like
in the original code.
Note that running a new test will stop any in progress test.
2. When built-in in the kernel...
The module parameters that is supplied to the kernel command line will be used
for the first performed test. After user gets a control, the test could be
interrupted or re-run with same or different parameters. For the details see
the above section "1. When dmatest is built as a module..."
In both cases the module parameters are used as initial values for the test case.
You always could check them at run-time by running
% grep -H . /sys/module/dmatest/parameters/*
