We have a Lenovo machine with the codec ALC294 on it, without the
patch, the Node 0x0b is regarded as the loopback mixer, but the Node
0x0b in this codec is "Vendor Defined Widget" instead of the audio
mixer, please see the log below:
Node 0x0b [Vendor Defined Widget] wcaps 0xf00000: Mono
Control: name="Beep Playback Volume", index=0, device=0
ControlAmp: chs=3, dir=In, idx=4, ofs=0
Control: name="Beep Playback Switch", index=0, device=0
ControlAmp: chs=3, dir=In, idx=4, ofs=0
And I have consulted with Realtek, so far the ALC234/274/294 all don't
have loopback mixer.

Since commit:
af2cf278ef4f ("x86/mm/hotplug: Don't remove PGD entries in remove_pagetable()")
we no longer free PUDs so that we do not have to synchronize
all PGDs on hot-remove/vfree().
But the new 5-level page table patchset reverted that for 4-level
page tables, in the following commit:
f2a6a7050109: ("x86: Convert the rest of the code to support p4d_t")
This patch restores the damage and disables free_pud() if we are in the
4-level page table case, thus avoiding BUG_ON() after hot-remove.

ARM64 depends on the macro __AARCH64EB__ being defined or not
to correctly select or define endian-specific macros, structures
or pieces of code.
This macro is predefined by the compiler but sparse knows nothing
about it and thus may pre-process files differently from what
gcc would.
Fix this by passing '-D__AARCH64EL__' or '-D__AARCH64EB__' to
sparse depending of the endianness of the kernel, like defined
by GCC.
Note: In most case it won't change anything since most arm64 use
little-endian (but an allyesconfig would use big-endian!).

If we write a relocation into the buffer, we require our own implicit
synchronisation added after the start of the execbuf, outside of the
user's control. As we may end up clflushing, or doing the patch itself
on the GPU, asynchronously we need to look at the implicit serialisation
on obj->resv and hence need to disable EXEC_OBJECT_ASYNC for this
object.
If the user does trigger a stall for relocations, we make sure the stall
is complete enough so that the batch is not submitted before we complete
those relocations.

Since we may track unfenced access (GPU access to the vma that
explicitly requires no fence), vma->last_fence may be set without any
attached fence (vma->fence) and so will not be flushed when we call
i915_vma_put_fence(). Since we stopped doing a full retire of the
activity trackers for unbind, we need to explicitly retire each tracker.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
Second set of IIO new device support, features and cleanups for the 4.13 cycle.
A few reverts here. One was a general failure to notice a device was already
supported by another driver. The second is due to a review comment pointing
out that the original patch was a bad idea and would break existing systems.
Reverts
* bma180
- Revert addition of support for the BMA250E it is already supported by
the bmc150-accel and better supported at that. Oops.
* hi8435
- The fix for cleanup of the reset gpio stuff isn't a good way to go. It
breaks systems where an inverting level convertor is used. The right fix
is to make the original devicetree correct - even if it involves patching
the devicetree in kernel.
New Device Support
* stm32-adc
- STM32H7 support and bindings.
Features
* core
- add a hardware triggered operating mode for systems in which the actual
trigger is never seen by the kernel. This is typically only used when
a device 'can' use other triggers, but if a particular magic one is
enabled the interrupt is effectively handled in hardware and we never see
it.
* st-lsm6dsx
- support active low interrupts.
* stm32-adc
- Make the core adc clock optional as not all hardware supported requires it.
- Make the bus clock optional in the per instance driver as it may be shared
by all instances of the ADC and is handled by the core.
- Rework to have a data structure representing the device type specific
elements.
* stm32-trigger (and counter)
- Use the INDIO_HARDWARE_TRIGGERED_MODE where appropriate.
- Add an attribute to configure device modes for quadrature counting etc.
Clean ups and minor fixes
* IIO core.
- use __sysfs_match_string() helper rather than open coding the same.
* ad7791
- use sysfs_match_string() helper rather than open coding the same.
* aspeed-adc
- handle return value of clk_prepare_enable
* cpcap
- Fix default register values and ensure the battery thermistor is enabled
correctly.
- Fix the reported die temperature where we can - docs are lacking.
- Remove the hung interrupt quirk as no longer happens due to fix in the
mfd driver.
* hi8435
- Remove &s from hi8435_info definition as unneeded and inconsistent.
* hid-sensor-trgger
- Add kconfig depends on IIO_BUFFER (fixes patch in previous series)
* ina2xx
- Make the use of iio_info_mask* elements consistent for all channels.
This doesn't have any visible effect, but acts as clear documentation of
which channels various resulting attributes apply to.
* lpc32xx
- handle the return value of clk_prepare_enable.
* meson-saradc
- NULL instead of 0 for pointer.
* mma9551
- use NULL for GPIO connection ID to aid implementation fo ACPI support.
Here the connection ID doesn't actually tell us anything and it is much
easier to deal with the driver if it's not there.
* mpu6050
- Fix lock issues through use of a local mux.
- Replace sprintf with scnprintf as appropriate.
- Check whoami against all known values. This allows for a small number of
boards where we are really fishing for the part not being present at all.
It is unfortunately common to have undescribed changes to use newer chips.
We paper over this but just emitting a warning for those cases as long as
we know about.
* mxs-lradc
- Fix some non static warnings.
* rcar-adc
- Part of making the naming for this part consistent across the kernel.
* st_accel
- drop some spi_device_id entries for variants with no SPI support
* st_magn
- drop some spi_device_id entries for variants with no SPI support.
* sx9500
- Use devm_gpiod_get instead of indexed value with an index of 0 on all
occasions.
* twl4030
- Drop unused twl4030_get_madc_conversion as callers removed now throughout
kernel.
- Unexport twl4030_madc_conversion() as no used only within this driver.
- Drop twl4030_madc_user_params as not used now.
- Drop twl4030_madc_request.func_cb as not used now.
- Fold the twl4030-madc.h header into the driver as no longer used anywhere
else in the kernel.
* xilinx
- Handle the return value of clk_prepare_enable

This is a preparatory patch to use timespec64 as the basic type

The davinci remoteproc driver is currently de-asserting the reset in
its rproc .start() ops, but is not asserting the reset in its .stop()
ops. This leaves the remote processor to not boot properly when using
the sysfs 'state' variable between multiple start and stop operations.
On the other hand, a reset is being asserted unconditionally in the
driver remove function to alleviate some of these issues.
Move this reset assertion logic into the .stop() ops implementation
to fix the sysfs state-machine and the unbalanced reset. The logic
from remove is still effective since .stop() ops will be invoked
during the remove due to the enabled 'auto-boot' support. The probe
already has support for asserting the reset in case the DSP is not
in reset for some reason.

The reset_assert() function is used to make sure the DSP remote
processor is in a reset state regardless of its previous state.
The driver relies on davinci_clk_reset_{assert,deassert}()
functions for reset management which take in a clock parameter.
The assert_reset() performs a clk_get()/clk_put() cycle to
acquire the clock handle to use with this function. This is
totally unnecessary and the code can be simplified to use
the clock acquired during probe and directly use the reset
functions, so simplify this logic.

The davinci remoteproc driver requires a CMA pool for allocating
memory for virtio vrings/buffers and other sections of the firmware
image. The allocations are done using the DMA API. The CMA option is
currently selected automatically on systems with MMU when davinci
remoteproc is enabled, switch this to a saner depends on dependency
convention. The dependency is also updated to use the DMA_CMA kconfig
symbol that is used for CMA allocations using the DMA API, the CMA
dependency is inherited implicitly.

Jag Raman says:
====================
sparc64: Add MDESC & VIO support for VCC
This series of patches is part of an effort to add VCC (Virtual Console
Concentrator) support to Linux.
VCC enables the virtualization of serial console on SPARC processors. VCC
provides access to the guest domain's serial console.
VCC depends on some core functionalities in the linux kernel for SPARC. The
functionalities include LDC (Logical Domain Channels), MDESC (Machine
Descriptor) and VIO (Virtual IO protocol). In order for VCC to be enabled,
it requires that these core functionalities support them.
This series of patches adds MDESC & VIO support to enable VCC on Linux. It
is the second batch of changes to enable VCC.
This version of the series addresses the following changes
suggested by Dave Miller
Patch 4/5:
- "name" field in vdev_port md_node_info is declared as "const char *"
- Code has been modified to dynamically allocate & free "name" in
vdev_port md_node_info
- Parameters to mdesc_get_node(), mdesc_get_node_info() &
mdesc_get_node_ops() have been updated to use "const char *"
Patch 6/5:
- "node_name" parameter in vio_create_one() has been
changed to "const char *" type from "char *"
- Typecasts in vio_create_one() invocations to convert
"const char *" to "char *" have been removed
Patch 11/5:
- Invocations of mdesc_node_get() & mdesc_get_node_info()
have been updated to use the prototypes defined in patch 4/5

====================
wireless-drivers-next patches for 4.13
New features and bug fixes to quite a few different drivers, but
nothing really special standing out.
What makes me happy that we have now more vendors actively
contributing to upstream drivers. In this pull request we have patches
from Broadcom, Intel, Qualcomm, Realtek and Redpine Signals, and I
still have patches from Marvell and Quantenna pending in patchwork. Now
that's something comparing to how things looked 11 years ago in Jeff
Garzik's "State of the Union: Wireless" email:
https://lkml.org/lkml/2006/1/5/671
Major changes:
wil6210
* add low level RF sector interface via nl80211 vendor commands
* add module parameter ftm_mode to load separate firmware for factory
testing
* support devices with different PCIe bar size
* add support for PCIe D3hot in system suspend
* remove ioctl interface which should not be in a wireless driver
ath10k
* go back to using dma_alloc_coherent() for firmware scratch memory
* add per chain RSSI reporting
brcmfmac
* add support multi-scheduled scan
* add scheduled scan support for specified BSSIDs
* add support for brcm43430 revision 0
wlcore
* add wil1285 compatible
rsi
* add RS9113 USB support
iwlwifi
* FW API documentation improvements (for tools and htmldoc)
* continuing work for the new A000 family
* bump the maximum supported FW API to 31
* improve the differentiation between 8000, 9000 and A000 families

sctp: RFC 4960 Errata fixes
This patchset contains fixes for 4 Errata topics from
https://tools.ietf.org/html/draft-ietf-tsvwg-rfc4960-errata-01
Namely, sections:
3.12. Order of Adjustments of partial_bytes_acked and cwnd
3.22. Increase of partial_bytes_acked in Congestion Avoidance
3.26. CWND Increase in Congestion Avoidance Phase
3.27. Refresh of cwnd and ssthresh after Idle Period
Tests performed with netperf using net namespaces, with drop rates at
0%, 0.5% and 1% by netem, IPv4 and IPv6, 10 runs for each combination.
I couldn't spot differences on the stats. With and without these patches
the results vary in a similar way in terms of throughput and
retransmissions.
Tests with 20ms delay and 20ms delay + drops at 0.5% and 1% also had
results in a similar way, no noticeable difference.
Looking at cwnd, it was possible to notice slightly lower values being
used while still sustaining same throughput profile.

RFC 4960 Errata 3.27 identifies that ssthresh should be adjusted to cwnd
because otherwise it could cause the transport to lock into congestion
avoidance phase specially if ssthresh was previously reduced by some
packet drop, leading to poor performance.
The Errata says to adjust ssthresh to cwnd only once, though the same
goal is achieved by updating it every time we update cwnd too. The
caveat is that we could take longer to get back up to speed but that
should be compensated by the fact that we don't adjust on RTO basis (as
RFC says) but based on Heartbeats, which are usually way longer.

RFC4960 Errata 3.26 identified that at the same time RFC4960 states that
cwnd should never grow more than 1*MTU per RTT, Section 7.2.2 was
underspecified and as described could allow increasing cwnd more than
that.
This patch updates it so partial_bytes_acked is maxed to cwnd if
flight_size doesn't reach cwnd, protecting it from such case.

As per RFC4960 Errata 3.22, this condition is not needed anymore as it
could cause the partial_bytes_acked to not consider the TSNs acked in
the Gap Ack Blocks although they were received by the peer successfully.
This patch thus drops the check for new Cumulative TSN Ack Point,
leaving just the flight_size < cwnd one.
