That solves several merge conflicts:
	Documentation/DocBook/media/v4l/subdev-formats.xml
	Documentation/devicetree/bindings/vendor-prefixes.txt
	drivers/staging/media/mn88473/mn88473.c
	include/linux/kconfig.h
	include/uapi/linux/media-bus-format.h

The ones at subdev-formats.xml and media-bus-format.h are not trivial.
That's why we opted to merge from DRM.

Sumit Semwal d8fbe341be dma-buf: cleanup dma_buf_export() to make it easily extensible
At present, dma_buf_export() takes a series of parameters, which
makes it difficult to add any new parameters for exporters, if required.

Make it simpler by moving all these parameters into a struct, and pass
the struct * as parameter to dma_buf_export().

While at it, unite dma_buf_export_named() with dma_buf_export(), and
change all callers accordingly.

David Henningsson 7d1b6e2932 ALSA: hda - fix "num_steps = 0" error on ALC256
The ALC256 does not have a mixer nid at 0x0b, and there's no
loopback path (the output pins are directly connected to the DACs).

This commit fixes an "num_steps = 0 for NID=0xb (ctl = Beep Playback Volume)"
error (and as a result, problems with amixer/alsamixer).

If there's pcbeep functionality, it certainly isn't controlled by setting an
amp on 0x0b, so disable beep functionality (at least for now).

Takamichi Horikawa 6d1f2f6056 ALSA: usb-audio: Fix audio output on Roland SC-D70 sound module
Roland SC-D70 reports its device class as vendor specific class and
the quirk QUIRK_AUDIO_FIXED_ENDPOINT was used for audio output.

In the quirks table the sampling rate was hard-coded to 44100 Hz
and therefore not worked when the sound module was in 48000 Hz mode.

In this change the quirk is changed to QUIRK_AUDIO_STANDARD_INTERFACE
but as the sound module reports incorrect bSubframeSize in its
descriptors, additional change is made in format.c to detect it and
to override it (which uses the existing code for Edirol SD-90).

Tested both when the sound module was in 44100 Hz mode and 48000 Hz
mode and both audio input and output. MIDI related part of the driver
is not touched.

Mengdong Lin 40cc2392f4 ALSA: hda - add AZX_DCAPS_I915_POWERWELL to Baytrail
This patch addes AZX_DCAPS_I915_POWERWELL to BYT (Baytrail).

Like Braswell and Skylake, the HDMI codec on Bytrail is also in the shared
power well with GPU. This power well must be turned on before we reset link
to probe the codec, to avoid communication failure with the codec.

The side effect is that this power is always ON in S0 because the BYT HDMI
codec does not support EPSS or D3ClkStop and so the controller doesn't enter
D3 at runtime, and the HDMI codec and analog codec share a single physical
HD-A link and so we cannot reset the HD-A link freely when we re-enable the
power to use the HDMI codec.

Next step is to test if an AGP reset or double AGP reset on BYT HDMI codec is
okay to bring the HDMI codec back to a functional state after restoring the
power. If okay, we can bind the power on/off with the HDMI codec PM without
interrupting the analog audio.

Andreas Oetken 71cd26e76a altera tse: Error-Bit on tx-avalon-stream always set.
The Error-Bit on the avalon streaming interface of the
tx-dma-channel was always set. In SGMII configurations
this leads to error-symbols on the PCS and packet-rejection
on the receiver side (e.g. SGMII/1000Base-X connected switch).

This only applies to the tse-configuration with MSGDMA.

This issue was detected and fixed on a custom board with
a direct connection to a Marvell switch in SGMII-PHY-Mode.
(incl. custom patches for SGMII-PCS).

According to the datasheet if ff_tx_err (avalon-streaming)
is set it is forwarded to gm_tx_err. As a result the PCS
is forwarding the error by sending a "/V/"-caracter.

David S. Miller 91f5bd8437 Merge branch 'ppp_csum_unset'
Tom Herbert says:

====================
net: Fix "hw csum failure" message flood for ppp tunnel

This patch set addresses bug "Bug 95171 - "hw csum failure" message
flood for ppp tunnel since upgrade to 3.16". The problem is that pppoe
is being used over UDP with UDP checksusm enabled. On receive
checksum conversion turns checksum-unnecessary in checksum-
complete. The PPP receive functions do not properly pull
the checksum over its headers, so that when an encapsulated
checksums is considered the checksum-complete value is incorrect.

This patch adds skb_checksum_complete_unset which can be called
in the receive path in lieu of pulling checksum complete in
layer. This is useful when the packet is being modified (e.g.
decompressed) and the checksum-complete value is no longer
relevant.

In the ppp_receive_frame we call skb_checksum_complete_unset to toss
out checksum-complete. This should eliminate the reported messages.
Alternatively, we could add skb_postpull_rcsum and probably
special case handling for VJ compression if maintaining the
checksum-complete is needed (not clear to me this is worth the
effort).

I haven't tested this since setting up the failure scenario doesn't
seem trivial to configure.

Linus Torvalds b153f1d37a SCSI misc on 20150419
I'd like to say these were a set of regressions for the recent merge window
 code.  Unfortunately, they all predate the merge window code (stable cc'd).
 There's two fixes for data integrity (mostly only showing up on module
 removal), an mvsas crash with expander attached SATA devices which goes back
 to the dawn of the driver but is only just being picked up as sas expanders
 become a standard item in low end server hardware, an am53c974 one because the
 interrupt data isn't fully initialised before the line is and a megaraid_sas
 one because it uses smp_processor_id() to select MSI-X queues and that now
 triggers a WARN_ON().

Joakim Tjernlund a068833bbf pppoe: Lacks DST MAC address check
A pppoe session is identified by its session ID and MAC address.
Currently pppoe does not check if the received pkg has the correct
MAC address. This is a problem when the eth I/F is in promisc mode
as then any DST MAC address is accepted.

Sebastian Pöhn 2ab957492d ip_forward: Drop frames with attached skb->sk
Initial discussion was:
[FYI] xfrm: Don't lookup sk_policy for timewait sockets

Forwarded frames should not have a socket attached. Especially
tw sockets will lead to panics later-on in the stack.

This was observed with TPROXY assigning a tw socket and broken
policy routing (misconfigured). As a result frame enters
forwarding path instead of input. We cannot solve this in
TPROXY as it cannot know that policy routing is broken.

Linus Torvalds f4d03bd143 smp: don't use 16-bit words for atomic accesses
Yes, it should work, but it's a bad idea.  Not only did ARM64 not have
the 16-bit access code (there's a separate patch to add it), it's just
not a good atomic type.  Some architectures fundamentally don't do
atomic accesses in them (alpha), and it's not like it saves any space
here anyway because of structure packing issues.

We normally should aim for flags to be "unsigned int" or "unsigned
long".  And if space is at a premium, use a single byte (although that
causes problems on alpha again).  There might be very special cases
where a 16-byte entity is really wanted, but this is not one of them.
