The commit d7ba858a7f (ALSA: fm801: implement TEA575x tuner autodetection)

In ALSA firewire stack, drivers basically has no control elements. This
is due to the fact that each model has own functionality even if they use
the same communication chipset. Implementing all of the functionalities in
kernel space unreasonably increases our efforts to maintain the stack. In
most case, these functionalities can be implemented in userspace via Linux
fw character devices.
However, ALSA OXFW driver has control elements comes from old
firewire-speakers driver. Adding the elements is in a file names as
'oxfw-control.c', while the elements are really model-specific. The
name is confusing because it gives an idea to handle control elements
for all of OXFW-based models.

Intel Atom processors seem to have a problem at recording when
bdl_pos_adj is set to an odd value. When a value like 1 is used, it
may drop the samples unexpectedly. Actually, for the old Atoms, we
used to set AZX_DRIVER_SCH type, and this assigns 32 as default.
Meanwhile the newer chips, Baytrail and Braswell, are set as
AZX_DRIVER_PCH, and the lower default value, 1, is assigned.
This patch changes the default values for these chipsets to a safer
default, 32, again. Since changing the driver type (AZX_DRIVER_XXX)
leads to the rename of the driver string, it would result in a
possible regression. So, we can't change the type. Instead, in this
patch, manual (ugly) PCI ID checks are added on top.
A drawback by this increase is the slight increase of the latency, but
it's a sub-ms order in normal situations, so mostly negligible.

Since we have a new audio component ops to fetch the current ELD and
state now, we can reduce the usage of unsol event of HDMI/DP pins.
The unsol event isn't only unreliable, but it also needs the power
up/down of the codec and link at each time, which is a significant
power and time loss.
In this patch, the jack creation and unsol/jack event handling are
modified to use the audio component for the dedicated Intel chips.
The jack handling got slightly more codes than a simple usage of
hda_jack layer since we need to deal directly with snd_jack object;
the hda_jack layer is basically designed for the pin sense read and
unsol events, both of which aren't used any longer in our case.

Here are the patchset to add get_eld op to audio component for
communicating more directly between i915 and HD-audio.
Currently, the HDMI/DP audio status and ELD are notified and obtained
via the hardware-level communication over HD-audio unsolicited event
and verbs although the graphics driver holds the exactly same
information. As we already have a notification via audio component,
this is another step forward; namely, the audio driver may fetch
directly the audio status and ELD via the new component op.

This patch adds a reverse mapping from a digital port number to
intel_encoder object containing the corresponding intel_digital_port.
It simplifies the query of the encoder a lot.
Note that, even if it's a valid digital port, the dig_port_map[] might
point still to NULL -- usually it implies a DP MST port. Due to this
fact, the NULL check in each place has no WARN_ON() and just skips the
port. Once when the situation changes in future, we might introduce
WARN_ON() for a more strict check.

Implement a new i915_audio_component_ops, get_eld(). It's called by
the audio driver to fetch the current audio status and ELD of the
given HDMI/DP port. It returns the size of expected ELD bytes if it's
valid, zero if no valid ELD is found, or a negative error code. The
current state of audio on/off is stored in the given pointer, too.
Note that the returned size isn't limited to the given max bytes. If
the size is greater than the max bytes, it means that only a part of
ELD has been copied back.
For achieving this implementation, a new field audio_connector is
added to struct intel_digital_port. It points to the connector
assigned to the given digital port. It's set/reset at each audio
enable/disable call in intel_audio.c, and protected with av_mutex.

Due to the recent change, HDA controller driver for Intel PCH tries to
bind i915 audio component always at the probe time no matter whether
HDMI/DP codec is found. This is, however, superflulous for old
chipsets (e.g. on IVB) where they don't have always the HDMI/DP codecs
but often have only a discrete GPU instead.
For the newer chipsets, we need already the i915 binding from the
beginning due to power well control. Meanwhile, for older chipsets
where we don't need power well, we don't need the i915 binding at the
controller level.
This patch removes again the i915 binding in the HDA controller driver
for old Intel PCHs, but adds the binding in HDMI/DP codec driver
instead. This allows still the use of the direct notification from
the graphics driver while we can avoid the unnecessary load of i915
driver for machines only with another GPU.

The OSS sound drivers used to rely on virt_to_bus(), but don't any more,
so we can remove the Kconfig dependency.
As a lot of architectures don't provide VIRT_TO_BUS any more, removing
the dependency in sounds/oss/ would make the deprecated drivers appear
there, which we probably don't want. Instead I'm replacing the
simple dependency with 'VIRT_TO_BUS || RPC || NETWINDER' so we can
still build these sound drivers for the platforms that need them,
but don't change anything on other architectures.
As a follow-up, we can remove the virt_to_bus() implementation
and Kconfig symbol in the ARM architecture.

snd-hda-intel driver tries to bind with i915 audio component always
when AZX_DCAPS_I915_POWERWELL is set in the driver caps. This was
mostly OK in the past, as the flag was applied only to a limited set
of devices, namely, Haswell and Broadwell. On these machines, i915
graphics is almost mandatory as long as HDMI/DP is concerned.
Recently the application of i915 binding was widened to more Intel
chips. On these chips, the chance of a kernel without i915 graphics
is much higher, and such user would hit an error like:
snd_hda_intel 0000:00:1b.0: failed to add i915 component master (-19)
Although the error itself is harmless, it's certainly superfluous even
to try binding with i915, if we already know that there isn't any.
This patch fixes it by simply defining AZX_DCAPS_I915_POWERWELL as 0
in the case without i915. Then all codes referring to this flag will
be optimized out by the compiler.

The recent commit [6603249dcd: ALSA: hda - Enable audio component

don't need i915 binding, and yet the driver has a check of i915
binding and complains like
Haswell must be built with CONFIG_SND_HDA_I915
This error is false-positive, and it should be put only for HSW/BDW,
instead of all devices that may be bound with i915.
This patch fixes the condition to check, as well as rephrasing the
message specific to HSW/BDW HDMI/DP.

Many codecs, typically found on Realtek codecs, have the analog
loopback path merged to the secondary input of the middle of the
output paths. Currently, we don't offer the dynamic switching in such
configuration but let each loopback path mute by itself.
This should work well in theory, but in reality, we often see that
such a dead loopback path causes some background noises even if all
the elements get muted. Such a problem has been fixed by adding the
quirk accordingly to disable aamix, and it's the right fix, per se.
The only problem is that it's not so trivial to achieve it; user needs
to pass a hint string via patch module option or sysfs.
This patch gives a bit improvement on the situation: it adds "Loopback
Mixing" control element for such codecs like other codecs (e.g. IDT or
VIA codecs) with the individual loopback paths. User can turn on/off
the loopback path simply via a mixer app.
For keeping the compatibility, the loopback is still enabled on these
codecs. But user can try to turn it off if experiencing a suspicious
background or click noise on the fly, then build a static fixup later
once after the problem is addressed.
Other than the addition of the loopback enable/disablement control,
there should be no changes.

Pull drm fixes from Dave Airlie:
"A bunch of change across the board, the main things are some vblank
fallout in radeon and nouveau required some work, but I think this
should fix it all. There is also one drm fix for an oops in vmwgfx
with how we pass the drm master around.
The rest is just some amdgpu, i915, imx and rockchip fixes.
Probably more than I'd like at this point, but hopefully things settle
down now"

When restarting a syscall with regs->ax == -ERESTART_RESTARTBLOCK,
regs->ax is assigned to a restart_syscall number. For x32 tasks, this
syscall number must have __X32_SYSCALL_BIT set, otherwise it will be
an x86_64 syscall number instead of a valid x32 syscall number. This
issue has been there since the introduction of x32.

MPX decodes instructions in order to tell which bounds register
was violated. Part of this decoding involves looking at the "REX
prefix" which is a special instrucion prefix used to retrofit
support for new registers in to old instructions.
The X86_REX_*() macros are defined to return actual bit values:
#define X86_REX_R(rex) ((rex) & 4)
*not* boolean values. However, the MPX code was checking for
them like they were booleans. This might have led to us
mis-decoding the "REX prefix" and giving false information out to
userspace about bounds violations. X86_REX_B() actually is bit 1,
so this is really only broken for the X86_REX_X() case.
Fix the conditionals up to tolerate the non-boolean values.
