git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- remove of atomisp driver from staging, as nobody would have time to
dedicate huge efforts to fix all the problems there. Also, we have a
feeling that the driver may not even run the way it is.
- move Zoran driver to staging, in order to be either fixed to use VB2
and the proper media kAPIs or to be removed
- remove videobuf-dvb driver, with is unused for a while
- some V4L2 documentation fixes/improvements
- new sensor drivers: imx258 and ov7251
- a new driver was added to allow using I2C transparent drivers
- several improvements at the ddbridge driver
- several improvements at the ISDB pt1 driver, making it more coherent
with the DVB framework
- added a new platform driver for MIPI CSI-2 RX: cadence
- now, all media drivers can be compiled on x86 with COMPILE_TEST
- almost all media drivers now build on non-x86 architectures with
COMPILE_TEST
- lots of other random stuff: cleanups, support for new board models,
bug fixes, etc

git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest
Pull Kselftest update from Shuah Khan:
- Work to restructure timers test suite to move PIE out of rtctest from
Alexandre Belloni.
- Several minor spelling and bug fixes.
- New cgroup tests from Roman Gushchin and Mike Rapoport.
- Kselftest framework changes to handle and report skipped tests
correctly.
Prior to these changes, framework treated all non-zero return codes
from tests as failures. When tests are skipped with non-zero return
code, due to unmet dependencies and/or unsupported configuration,
reporting them as failed lead to false negatives on the tests that
couldn't be run.
- Fixes to test Makefiles to remove unnecessary RUN_TESTS and
EMIT_TESTS overrides and use common defines from lib.mk.
- Fixes to several tests to return correct Kselftest skip code.
- Changes to improve test output.

Pull Kconfig updates from Masahiro Yamada:
"Kconfig now supports new functionality to perform textual
substitution. It has been a while since Linus suggested to move
compiler option tests from makefiles to Kconfig. Finally, here it is.
The implementation has been generalized into a Make-like macro
language.
Some built-in functions such as 'shell' are provided. Variables and
user-defined functions are also supported so that 'cc-option',
'ld-option', etc. are implemented as macros.
Summary:
- refactor package checks for building {m,n,q,g}conf
- remove unused/unmaintained localization support
- remove Kbuild cache

Daniel Borkmann says:
====================
pull-request: bpf-next 2018-06-05
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add a new BPF hook for sendmsg similar to existing hooks for bind and
connect: "This allows to override source IP (including the case when it's
set via cmsg(3)) and destination IP:port for unconnected UDP (slow path).
TCP and connected UDP (fast path) are not affected. This makes UDP support
complete, that is, connected UDP is handled by connect hooks, unconnected
by sendmsg ones.", from Andrey.
2) Rework of the AF_XDP API to allow extending it in future for type writer
model if necessary. In this mode a memory window is passed to hardware
and multiple frames might be filled into that window instead of just one
that is the case in the current fixed frame-size model. With the new
changes made this can be supported without having to add a new descriptor
format. Also, core bits for the zero-copy support for AF_XDP have been
merged as agreed upon, where i40e bits will be routed via Jeff later on.
Various improvements to documentation and sample programs included as
well, all from Björn and Magnus.
3) Given BPF's flexibility, a new program type has been added to implement
infrared decoders. Quote: "The kernel IR decoders support the most
widely used IR protocols, but there are many protocols which are not
supported. [...] There is a 'long tail' of unsupported IR protocols,
for which lircd is need to decode the IR. IR encoding is done in such
a way that some simple circuit can decode it; therefore, BPF is ideal.
[...] user-space can define a decoder in BPF, attach it to the rc
device through the lirc chardev.", from Sean.
4) Several improvements and fixes to BPF core, among others, dumping map
and prog IDs into fdinfo which is a straight forward way to correlate
BPF objects used by applications, removing an indirect call and therefore
retpoline in all map lookup/update/delete calls by invoking the callback
directly for 64 bit archs, adding a new bpf_skb_cgroup_id() BPF helper
for tc BPF programs to have an efficient way of looking up cgroup v2 id
for policy or other use cases. Fixes to make sure we zero tunnel/xfrm
state that hasn't been filled, to allow context access wrt pt_regs in
32 bit archs for tracing, and last but not least various test cases
for fixes that landed in bpf earlier, from Daniel.
5) Get rid of the ndo_xdp_flush API and extend the ndo_xdp_xmit with
a XDP_XMIT_FLUSH flag instead which allows to avoid one indirect
call as flushing is now merged directly into ndo_xdp_xmit(), from Jesper.
6) Add a new bpf_get_current_cgroup_id() helper that can be used in
tracing to retrieve the cgroup id from the current process in order
to allow for e.g. aggregation of container-level events, from Yonghong.
7) Two follow-up fixes for BTF to reject invalid input values and
related to that also two test cases for BPF kselftests, from Martin.
8) Various API improvements to the bpf_fib_lookup() helper, that is,
dropping MPLS bits which are not fully hashed out yet, rejecting
invalid helper flags, returning error for unsupported address
families as well as renaming flowlabel to flowinfo, from David.
9) Various fixes and improvements to sockmap BPF kselftests in particular
in proper error detection and data verification, from Prashant.
10) Two arm32 BPF JIT improvements. One is to fix imm range check with
regards to whether immediate fits into 24 bits, and a naming cleanup
to get functions related to rsh handling consistent to those handling
lsh, from Wang.
11) Two compile warning fixes in BPF, one for BTF and a false positive
to silent gcc in stack_map_get_build_id_offset(), from Arnd.
12) Add missing seg6.h header into tools include infrastructure in order
to fix compilation of BPF kselftests, from Mathieu.
13) Several formatting cleanups in the BPF UAPI helper description that
also fix an error during rst2man compilation, from Quentin.
14) Hide an unused variable in sk_msg_convert_ctx_access() when IPv6 is
not built into the kernel, from Yue.
15) Remove a useless double assignment in dev_map_enqueue(), from Colin.

ASoC: Updates for v4.18
This is a very big update, mainly due to a huge set of new drivers some
of which are individually very large. We also have a lot of fixes for
the topology stuff, several of the users have stepped up and fixed some
the serious issues there, and continued progress on the transition away
from CODEC specific drivers to generic component drivers.
- Many fixes for the topology code, including fixes for the half done
v4 ABI compatibility from Guenter Roeck and other ABI fixes from
Kirill Marinushkin.
- Lots of cleanup for Intel platforms based on Realtek CODECs from Hans
de Goode.
- More followups on removing legacy CODEC things and transitioning to
components from Morimoto-san.
- Conversion of OMAP DMA to the new, more standard SDMA-PCM driver.
- A series of fixes and updates to the rather elderly Cirrus Logic SoC
drivers from Alexander Sverdlin.
- Qualcomm DSP support from Srinivas Kandagatla.
- New drivers for Analog SSM2305, Atmel I2S controllers, Mediatek
MT6351, MT6797 and MT7622, Qualcomm DSPs, Realtek RT1305, RT1306 and
RT5668 and TI TSCS454

- Lots of tidying up changes all across the map for Linux's formal
memory/locking-model tooling, by Alan Stern, Akira Yokosawa, Andrea

Notable changes beyond an overall update in the tooling itself is the
tidying up of spin_is_locked() semantics, which spills over into the
kernel proper as well.
- qspinlock improvements: the locking algorithm now guarantees forward
progress whereas the previous implementation in mainline could starve
threads indefinitely in cmpxchg() loops. Also other related cleanups
to the qspinlock code (Will Deacon)

====================
Intel Wired LAN Driver Updates 2018-06-04
This series contains a smorgasbord of updates to documentation, e1000e,
igb, ixgbe, ixgbevf and i40e.
Benjamin Poirier fixes a potential kernel crash due to NULL pointer
dereference in e1000e.
Jeff updates the kernel documentation for e100 and e1000 to correct
default values and URLs which were incorrect in the documentation. Also
took the time to update these to the new reStructured text format for
kernel documentation.
Joanna Yurdal fixes a missing PTP transmit timestamp by ensuring that
TSICR gets cleared when ICR is cleared.
Sergey updates igb to reset all the transmit queues at one time so that
we only have to wait once for all the queues to be reset.
Alex fixes ixgbevf so that malicious driver detection (MDD) can co-exist
with XDP.
Emil and Tony extend the RTNL lock to ensure we get the most up-to-date
values for the bits and avoid a possible race condition when going down.
YueHaibing from Huawei introduces a helper function in ixgbe for
operation reads to simplify the code a bit more.
Daniel Borkmann adds support for XDP meta data when using build SKB
for i40e.
Shannon Nelson provides twp fixes for the IPSec code in ixgbe, first is
to make sure we do not try to offload the decryption of any incoming
packet that is destined for the management engine. The other fix is to
resolve a cast problem introduced by a sparse cleanup patch.

In Certain QCOM SoCs like apq8096 and msm8996 that have KRYO processors,
the CPU frequency subset and voltage value of each OPP varies
based on the silicon variant in use. Qualcomm Process Voltage Scaling Tables
defines the voltage and frequency value based on the msm-id in SMEM
and speedbin blown in the efuse combination.
The qcom-cpufreq-kryo driver reads the msm-id and efuse value from the SoC
to provide the OPP framework with required information.
This is used to determine the voltage and frequency value for each OPP of
operating-points-v2 table when it is parsed by the OPP framework.

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.

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.

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.

Documentation for Renesas R-Car MIPI CSI-2 receiver. The CSI-2 receivers
are located between the video sources (CSI-2 transmitters) and the video
grabbers (VIN) on Gen3 of Renesas R-Car SoC.
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
a few possible routes which are set by hardware limitations, which are
different for each SoC in the Gen3 family.

The current hugetlbfs maintainer has not been active for more than a few
years. I have been been active in this area for more than two years and
plan to remain active in the foreseeable future.
Also, update the hugetlbfs entry to include linux-mm mail list and
additional hugetlbfs related files. hugetlb.c and hugetlb.h are not
100% hugetlbfs, but a majority of their content is hugetlbfs related.

This driver hasn't been tested in a long, long time. The hardware is
ancient and pretty much obsolete. This driver also needs to be converted
to newer media frameworks (vb2!) but due to the lack of time and interest
that is unlikely to happen.
So this driver is a prime candidate for removal. If someone is interested
in working on this driver to prevent its removal, then please contact the
linux-media mailinglist.
