f274baa49b ALSA: usb-audio: Allow non-vmalloc buffer for PCM buffers
Currently, USB-audio driver allocates the PCM buffer via vmalloc(), as
this serves merely as an intermediate buffer that is copied to each
URB transfer buffer.  This works well in general on x86, but on some
archs this may result in cache coherency issues when mmap is used.
OTOH, it works also on such arch unless mmap is used.

This patch is a step for mitigating the inconvenience; a new module
option "use_vmalloc" is provided so that user can choose to allocate
the DMA coherent buffer instead of the existing vmalloc buffer.
The drawback is that it'd be the standard dma_alloc_coherent() calls
and the system would require contiguous pages on non-x86 archs.

Note that it's a global option and not dynamically switchable since
the buffer is pre-allocated at the probe time.  In theory, it's
possible to be switchable, but it'd be trickier and racier.

As default use_vmalloc option is set to true, so that the old behavior
is kept.  For allowing the coherent mmap on ARM or MIPS, pass
use_vmalloc=0 option explicitly.

ba5e4426e8 virtio_net: Extend virtio to use VF datapath when available
This patch enables virtio_net to switch over to a VF datapath when STANDBY
feature is enabled and a VF netdev is present with the same MAC address.
It allows live migration of a VM with a direct attached VF without the need
to setup a bond/team between a VF and virtio net device in the guest.

It uses the API that is exported by the net_failover driver to create and
and destroy a master failover netdev. When STANDBY feature is enabled, an
additional netdev(failover netdev) is created that acts as a master device
and tracks the state of the 2 lower netdevs. The original virtio_net netdev
is marked as 'standby' netdev and a passthru device with the same MAC is
registered as 'primary' netdev.

The hypervisor needs to unplug the VF device from the guest on the source
host and reset the MAC filter of the VF to initiate failover of datapath
to virtio before starting the migration. After the migration is completed,
the destination hypervisor sets the MAC filter on the VF and plugs it back
to the guest to switch over to VF datapath.

This patch is based on the discussion initiated by Jesse on this thread.

cfc80d9a11 net: Introduce net_failover driver
The net_failover driver provides an automated failover mechanism via APIs
to create and destroy a failover master netdev and manages a primary and
standby slave netdevs that get registered via the generic failover
infrastructure.

The failover netdev acts a master device and controls 2 slave devices. The
original paravirtual interface gets registered as 'standby' slave netdev and
a passthru/vf device with the same MAC gets registered as 'primary' slave
netdev. Both 'standby' and 'failover' netdevs are associated with the same
'pci' device. The user accesses the network interface via 'failover' netdev.
The 'failover' netdev chooses 'primary' netdev as default for transmits when
it is available with link up and running.

This can be used by paravirtual drivers to enable an alternate low latency
datapath. It also enables hypervisor controlled live migration of a VM with
direct attached VF by failing over to the paravirtual datapath when the VF
is unplugged.

30c8bd5aa8 net: Introduce generic failover module
The failover module provides a generic interface for paravirtual drivers
to register a netdev and a set of ops with a failover instance. The ops
are used as event handlers that get called to handle netdev register/
unregister/link change/name change events on slave pci ethernet devices
with the same mac address as the failover netdev.

This enables paravirtual drivers to use a VF as an accelerated low latency
datapath. It also allows migration of VMs with direct attached VFs by
failing over to the paravirtual datapath when the VF is unplugged.

316d55d55f Documentation: kconfig: document a new Kconfig macro language
Add a document for the macro language introduced to Kconfig.

The motivation of this work is to move the compiler option tests to
Kconfig from Makefile.  A number of kernel features require the
compiler support.  Enabling such features blindly in Kconfig ends up
with a lot of nasty build-time testing in Makefiles.  If a chosen
feature turns out unsupported by the compiler, what the build system
can do is either to disable it (silently!) or to forcibly break the
build, despite Kconfig has let the user to enable it.  By moving the
compiler capability tests to Kconfig, features unsupported by the
compiler will be hidden automatically.

This change was strongly prompted by Linus Torvalds.  You can find
his suggestions [1] [2] in ML.  The original idea was to add a new
attribute with 'option shell=...', but I found more generalized text
expansion would make Kconfig more powerful and lovely.  The basic
ideas are from Make, but there are some differences.

104daea149 kconfig: reference environment variables directly and remove 'option env='
To get access to environment variables, Kconfig needs to define a
symbol using "option env=" syntax.  It is tedious to add a symbol entry
for each environment variable given that we need to define much more
such as 'CC', 'AS', 'srctree' etc. to evaluate the compiler capability
in Kconfig.

Adding '$' for symbol references is grammatically inconsistent.
Looking at the code, the symbols prefixed with 'S' are expanded by:
 - conf_expand_value()
   This is used to expand 'arch/$ARCH/defconfig' and 'defconfig_list'
 - sym_expand_string_value()
   This is used to expand strings in 'source' and 'mainmenu'

All of them are fixed values independent of user configuration.  So,
they can be changed into the direct expansion instead of symbols.

This change makes the code much cleaner.  The bounce symbols 'SRCARCH',
'ARCH', 'SUBARCH', 'KERNELVERSION' are gone.

sym_init() hard-coding 'UNAME_RELEASE' is also gone.  'UNAME_RELEASE'
should be replaced with an environment variable.

ARCH_DEFCONFIG is a normal symbol, so it should be simply referenced
without '$' prefix.

The new syntax is addicted by Make.  The variable reference needs
parentheses, like $(FOO), but you can omit them for single-letter
variables, like $F.  Yet, in Makefiles, people tend to use the
parenthetical form for consistency / clarification.

At this moment, only the environment variable is supported, but I will
extend the concept of 'variable' later on.

The variables are expanded in the lexer so we can simplify the token
handling on the parser side.

For example, the following code works.

[Example code]

  config MY_TOOLCHAIN_LIST
          string
          default "My tools: CC=$(CC), AS=$(AS), CPP=$(CPP)"

[Result]

  $ make -s alldefconfig && tail -n 1 .config
  CONFIG_MY_TOOLCHAIN_LIST="My tools: CC=gcc, AS=as, CPP=gcc -E"

Each CSI-2 device is connected to more than one VIN device which
simultaneously can receive video from the same CSI-2 device. Each VIN
device can also be connected to more than one CSI-2 device. The routing
of which links are used is controlled by the VIN devices. There are only

098afd9817 x86/pci-dma: remove the explicit nodac and allowdac option
This is something drivers should decide (modulo chipset quirks like
for VIA), which as far as I can tell is how things have been handled
for the last 15 years.

Note that we keep the usedac option for now, as it is used in the wild
to override the too generic VIA quirk.

3deb642f0d fs: introduce new ->get_poll_head and ->poll_mask methods
->get_poll_head returns the waitqueue that the poll operation is going
to sleep on.  Note that this means we can only use a single waitqueue
for the poll, unlike some current drivers that use two waitqueues for
different events.  But now that we have keyed wakeups and heavily use
those for poll there aren't that many good reason left to keep the
multiple waitqueues, and if there are any ->poll is still around, the
driver just won't support aio poll.

    PDK2 board, Engicam i.CoreM6 1.5 Quad/Dual MIPI starter kit,
    Kieback & Peter GmbH iMX6Q TPC board.
  - A series from Anson Huang to add a bunch of devices for i.MX6SX
    SabreAuto board, PMIC, IO expanders, FEC, Watchdog, LED and Touch.
  - Update i.MX7D for cpufreq support, using operating-points-v2
    bindings, correcting cpu supply name for voltage scaling.
  - Clean up unneeded 'codec-handle' property from imx25-pdk and
    imx53-tx53 device tree.
  - Switch SoC dtsi and NXP board dts files to use SPDX identifier.
  - Remove unnecessary '#address-cells/#size-cells' to fix DTC warning
    avoid_unnecessary_addr_size seen with W=1 switch.
  - A series from Rob Herring to fix DTC warning graph_endpoint seen with
    IPU OF graph when W=1 switch is on.
  - Update a few boards to use symbol name instead of hard-coding the
    input codes.
  - Update a number of boards to use IRQ_TYPE specifier instead of the
    raw value.
  - A few updates for i.MX6 RDU2 board: bumping SoC/PU operating points,
    adding assigned clocks for GPU, and enabling eGalax touchscreen.
  - A couple of i.MX51 RDU1 updates: limiting usbh1 to full-speed, and
    cleaning up eMMC device node.
  - Convert Hummingboard audio bindings from imx-audio-sgtl5000 to

Merge tag 'imx-dt-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/dt

i.MX device tree update for 4.18:
 - New boards support: BTicino i.MX6DL Mamoj board, DHCOM iMX6 SoM and
   PDK2 board, Engicam i.CoreM6 1.5 Quad/Dual MIPI starter kit,
   Kieback & Peter GmbH iMX6Q TPC board.
 - A series from Anson Huang to add a bunch of devices for i.MX6SX
   SabreAuto board, PMIC, IO expanders, FEC, Watchdog, LED and Touch.
 - Update i.MX7D for cpufreq support, using operating-points-v2
   bindings, correcting cpu supply name for voltage scaling.
 - Clean up unneeded 'codec-handle' property from imx25-pdk and
   imx53-tx53 device tree.
 - Switch SoC dtsi and NXP board dts files to use SPDX identifier.
 - Remove unnecessary '#address-cells/#size-cells' to fix DTC warning
   avoid_unnecessary_addr_size seen with W=1 switch.
 - A series from Rob Herring to fix DTC warning graph_endpoint seen with
   IPU OF graph when W=1 switch is on.
 - Update a few boards to use symbol name instead of hard-coding the
   input codes.
 - Update a number of boards to use IRQ_TYPE specifier instead of the
   raw value.
 - A few updates for i.MX6 RDU2 board: bumping SoC/PU operating points,
   adding assigned clocks for GPU, and enabling eGalax touchscreen.
 - A couple of i.MX51 RDU1 updates: limiting usbh1 to full-speed, and
   cleaning up eMMC device node.
 - Convert Hummingboard audio bindings from imx-audio-sgtl5000 to
   simple-audio-card, so that auxiliary audio devices such as external
   amplifiers can be supported.
 - Replace underscore with hyphen in aliases name to fix DTC warning
   alias_paths with W=1 switch.
 - A couple of updates on i.MX7D SAI and i.MX6ULL UART5 pin defines.
 - Other random and small changes.

579d76deb1 media: docs: clarify relationship between crop and selection APIs
Having two somewhat similar and largely overlapping APIs is confusing,
especially since the older one appears in the docs before the newer
and most featureful counterpart.

Clarify all of this in several ways:
 - swap the two sections
 - give a name to the two APIs in the section names
 - add a note at the beginning of the CROP API section
 - update note about VIDIOC_CROPCAP

Also remove a note that is incorrect (correct wording is in
vidioc-cropcap.rst).

We introduce a new KVM_VGIC_V3_ADDR_TYPE_REDIST_REGION attribute in
KVM_DEV_ARM_VGIC_GRP_ADDR group. It allows userspace to provide the
base address and size of a redistributor region

Compared to KVM_VGIC_V3_ADDR_TYPE_REDIST, this new attribute allows
to declare several separate redistributor regions.

So the whole redist space does not need to be contiguous anymore.
