93b943edfc ASoC: generic-dmaengine-pcm: Check NO_RESIDUE flag at runtime
Currently we have two different snd_soc_platform_driver structs in the generic
dmaengine PCM driver. One for dmaengine drivers that support residue reporting
and one for those which do not. When registering the PCM component we check
whether the NO_RESIDUE flag is set or not and use the corresponding
snd_soc_platform_driver. This patch modifies the driver to only have one
snd_soc_platform_driver struct where the pointer() callback checks the
NO_RESIDUE flag at runtime. This allows us to set the NO_RESIDUE flag after the
PCM component has been registered. This becomes necessary when querying whether
the dmaengine driver supports residue reporting from the dmaengine driver itself
since the DMA channel might only be requested after the PCM component has been
registered.

507205632d dma: Indicate residue granularity in dma_slave_caps
This patch adds a new field to the dma_slave_caps struct which indicates the
granularity with which the driver is able to update the residue field of the
dma_tx_state struct. Making this information available to dmaengine users allows
them to make better decisions on how to operate. E.g. for audio certain features
like wakeup less operation or timer based scheduling only make sense and work
correctly if the reported residue is fine-grained enough.

Right now four different levels of granularity are supported:
	* DESCRIPTOR: The DMA channel is only able to tell whether a descriptor has
	  been completed or not, which means residue reporting is not supported by
	  this channel. The residue field of the dma_tx_state field will always be
	  0.
	* SEGMENT: The DMA channel updates the residue field after each successfully
	  completed segment of the transfer (For cyclic transfers this is after each
	  period). This is typically implemented by having the hardware generate an
	  interrupt after each transferred segment and then the drivers updates the
	  outstanding residue by the size of the segment. Another possibility is if
	  the hardware supports SG and the segment descriptor has a field which gets
	  set after the segment has been completed. The driver then counts the
	  number of segments without the flag set to compute the residue.
	* BURST: The DMA channel updates the residue field after each transferred
	  burst. This is typically only supported if the hardware has a progress
	  register of some sort (E.g. a register with the current read/write address
	  or a register with the amount of bursts/beats/bytes that have been
	  transferred or still need to be transferred).

328089a471 ASoC: samsung: Don't set unused struct snd_pcm_hardware fields
The ASoC core assumes that the PCM component of the ASoC card transparently
moves data around and does not impose any restrictions on the memory layout or
the transfer speed. It ignores all fields from the snd_pcm_hardware struct for
the PCM driver that are related to this. Setting these fields in the PCM driver
might suggest otherwise though, so rather not set them.

d37bdf736d ASoC: samsung: Use ASoC dmaengine code where possible
Since all Exynos platforms have been converted to dmaengine and many of
the older platforms are in the process of conversion they do not need to
use the legacy s3c-dma APIs for DMA but can instead use the standard ASoC
dmaengine helpers. This both allows them to benefit from improvements
implemented in the generic code and supports multiplatform.

This patch includes some fixes from Padma for Exynos SoCs, her testing
was on a slightly earlier version of the patch due to unrelated breakage
preventing testing.

0ad7c00057 dma: add channel request API that supports deferred probe
dma_request_slave_channel() simply returns NULL whenever DMA channel
lookup fails. Lookup could fail for two distinct reasons:

a) No DMA specification exists for the channel name.
   This includes situations where no DMA specifications exist at all, or
   other general lookup problems.

b) A DMA specification does exist, yet the driver for that channel is not
   yet registered.

Case (b) should trigger deferred probe in client drivers. However, since
they have no way to differentiate the two situations, it cannot.

Implement new function dma_request_slave_channel_reason(), which performs
identically to dma_request_slave_channel(), except that it returns an
error-pointer rather than NULL, which allows callers to detect when
deferred probe should occur.

Eventually, all drivers should be converted to this new API, the old API
removed, and the new API renamed to the more desirable name. This patch
doesn't convert the existing API and all drivers in one go, since some
drivers call dma_request_slave_channel() then dma_request_channel() if
that fails. That would require either modifying dma_request_channel() in
the same way, or adding extra error-handling code to all affected
drivers, and there are close to 100 drivers using the other API, rather
than just the 15-20 or so that use dma_request_slave_channel(), which
might be tenable in a single patch.

acpi_dma_request_slave_chan_by_name() doesn't currently implement
deferred probe. It should, but this will be addressed later.

194c7dea00 ASoC: dmaengine: add custom DMA config to snd_dmaengine_pcm_config
Add fields to struct snd_dmaengine_pcm_config to allow custom:

- DMA channel names.

  This is useful when the default "tx" and "rx" channel names don't
  apply, for example if a HW module supports multiple channels, each
  having different DMA channel names. This is the case with the FIFOs
  in Tegra's AHUB. This new facility can replace
  SND_DMAENGINE_PCM_FLAG_CUSTOM_CHANNEL_NAME.

- DMA device

  This allows requesting DMA channels for a device other than the device
  which is registering the "PCM" driver. This is quite unusual, but is
  currently useful on Tegra. In much HW, and in Tegra20, each DAI HW
  module contains its own FIFOs which DMA writes to. However, in Tegra30,
  the DMA FIFOs were split out AHUB HW module, which then routes the data
  through a cross-bar, and into the DAI HW modules. However, the current
  ASoC driver structure does not expose this detail, and acts as if the
  FIFOs are still part of the DAI HW modules. Consequently, the "PCM"
  driver is registered with the DAI HW module, yet the DMA channels must
  be looked up in the AHUB HW module's device tree node. This new config
  field allows that to happen. Eventually, the Tegra drivers will be
  reworked to fully expose the AHUB, and this config field can be
  removed.

 3) IPv4 output cached route instantiation properly handles races
    involving two threads trying to install the same route, but we

    Alexei Starovoitov.

 4) Put protections in place to make sure that recvmsg() paths never
    accidently copy uninitialized memory back into userspace and also
    make sure that we never try to use more that sockaddr_storage for
    building the on-kernel-stack copy of a sockaddr.  Fixes from Hannes

 5) R8152 driver transmit flow bug fixes from Hayes Wang.

 6) Fix some minor fallouts from genetlink changes, from Johannes Berg
    and Michael Opdenacker.

Pull SLAB changes from Pekka Enberg:
 "The patches from Joonsoo Kim switch mm/slab.c to use 'struct page' for
  slab internals similar to mm/slub.c.  This reduces memory usage and
  improves performance:

Pull third set of powerpc updates from Benjamin Herrenschmidt:
 "This is a small collection of random bug fixes and a few improvements
  of Oops output which I deemed valuable enough to include as well.

  The fixes are essentially recent build breakage and regressions, and a
  couple of older bugs such as the DTL log duplication, the EEH issue
  with PCI_COMMAND_MASTER and the problem with small contexts passed to
  get/set_context with VSX enabled"

  powerpc/signals: Mark VSX not saved with small contexts
  powerpc/pseries: Fix SMP=n build of rng.c
  powerpc: Make cpu_to_chip_id() available when SMP=n
  powerpc/vio: Fix a dma_mask issue of vio
