Tomi Valkeinen 3d1d40b6a6 MAINTAINERS: make omapfb orphan
omapfb is not maintained by me anymore, so drop my name from the
maintainers, and mark omapfb as orphan.

At some point in the future we should mark omapfb as obsolete, but there
are still some features supported by omapfb which are not supported by
omapdrm, so we're not there yet.

Shawn Lin 6e0832fa43 PCI: Collect all native drivers under drivers/pci/controller/
Native PCI drivers for root complex devices were originally all in
drivers/pci/host/.  Some of these devices can also be operated in endpoint
mode.  Drivers for endpoint mode didn't seem to fit in the "host"
directory, so we put both the root complex and endpoint drivers in
per-device directories, e.g., drivers/pci/dwc/, drivers/pci/cadence/, etc.

These per-device directories contain trivial Kconfig and Makefiles and
clutter drivers/pci/.  Make a new drivers/pci/controllers/ directory and
collect all the device-specific drivers there.

No functional change intended.

 drivers, updates and fixes cycle as it seems.
 
 New drivers/subdrivers:
 
 - Actions Semiconductor S900 driver with more Actions
   variants for S700, S500 in the pipe. Also generic GPIO
   support on top of the same driver and IRQ support is in
   the pipe.
 
 - Renesas r8a77470 PFC support.
 
 - Renesas r8a77990 PFC support.
 
 - Allwinner Sunxi H6 R_PIO support.
 
 - Rockchip PX30 support.
 
 - Meson Meson8m2 support.
 
 - Remove support for the ill-fated Samsung Exynos 5440 SoC.
 
 Improvements:
 
 - Context save/restore support in pinctrl-single.
 
 - External interrupt support for the Mediatek MT7622.
 
 - Qualcomm ACPI HID QCOM8002 supported.
 
 Fixes:
 
 - Fix up suspend/resume support for Exynos 5433.
 
 - Fix Strago DMI fixes on the Intel Cherryview.

 - 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.

Linus Torvalds 0ad39cb3d7 Kconfig updates for v4.18
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
 
 - drop CONFIG_CROSS_COMPILE support
 
 - replace 'option env=' with direct variable expansion
 
 - add built-in functions such as 'shell'
 
 - support variables and user-defined functions
 
 - add helper macros as as 'cc-option'
 
 - add unit tests and a document of the new macro language
 
 - add 'testconfig' to help
 
 - fix warnings from GCC 8.1

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

   - drop CONFIG_CROSS_COMPILE support

   - replace 'option env=' with direct variable expansion

   - add built-in functions such as 'shell'

   - support variables and user-defined functions

   - add helper macros as as 'cc-option'

   - add unit tests and a document of the new macro language

   - add 'testconfig' to help

   - fix warnings from GCC 8.1"

Mathieu Desnoyers d7822b1e24 rseq: Introduce restartable sequences system call
Expose a new system call allowing each thread to register one userspace
memory area to be used as an ABI between kernel and user-space for two
purposes: user-space restartable sequences and quick access to read the
current CPU number value from user-space.

* Restartable sequences (per-cpu atomics)

Restartables sequences allow user-space to perform update operations on
per-cpu data without requiring heavy-weight atomic operations.

The restartable critical sections (percpu atomics) work has been started
by Paul Turner and Andrew Hunter. It lets the kernel handle restart of
critical sections. [1] [2] The re-implementation proposed here brings a
few simplifications to the ABI which facilitates porting to other
architectures and speeds up the user-space fast path.

Here are benchmarks of various rseq use-cases.

Test hardware:

arm32: ARMv7 Processor rev 4 (v7l) "Cubietruck", 2-core
x86-64: Intel E5-2630 v3@2.40GHz, 16-core, hyperthreading

The following benchmarks were all performed on a single thread.

* Per-CPU statistic counter increment

                getcpu+atomic (ns/op)    rseq (ns/op)    speedup
arm32:                344.0                 31.4          11.0
x86-64:                15.3                  2.0           7.7

* LTTng-UST: write event 32-bit header, 32-bit payload into tracer
             per-cpu buffer

                getcpu+atomic (ns/op)    rseq (ns/op)    speedup
arm32:               2502.0                 2250.0         1.1
x86-64:               117.4                   98.0         1.2

* liburcu percpu: lock-unlock pair, dereference, read/compare word

                getcpu+atomic (ns/op)    rseq (ns/op)    speedup
arm32:                751.0                 128.5          5.8
x86-64:                53.4                  28.6          1.9

* jemalloc memory allocator adapted to use rseq

Using rseq with per-cpu memory pools in jemalloc at Facebook (based on
rseq 2016 implementation):

The production workload response-time has 1-2% gain avg. latency, and
the P99 overall latency drops by 2-3%.

* Reading the current CPU number

Speeding up reading the current CPU number on which the caller thread is
running is done by keeping the current CPU number up do date within the
cpu_id field of the memory area registered by the thread. This is done
by making scheduler preemption set the TIF_NOTIFY_RESUME flag on the
current thread. Upon return to user-space, a notify-resume handler
updates the current CPU value within the registered user-space memory
area. User-space can then read the current CPU number directly from
memory.

Keeping the current cpu id in a memory area shared between kernel and
user-space is an improvement over current mechanisms available to read
the current CPU number, which has the following benefits over
alternative approaches:

- 35x speedup on ARM vs system call through glibc
- 20x speedup on x86 compared to calling glibc, which calls vdso
  executing a "lsl" instruction,
- 14x speedup on x86 compared to inlined "lsl" instruction,
- Unlike vdso approaches, this cpu_id value can be read from an inline
  assembly, which makes it a useful building block for restartable
  sequences.
- The approach of reading the cpu id through memory mapping shared
  between kernel and user-space is portable (e.g. ARM), which is not the
  case for the lsl-based x86 vdso.

On x86, yet another possible approach would be to use the gs segment
selector to point to user-space per-cpu data. This approach performs
similarly to the cpu id cache, but it has two disadvantages: it is
not portable, and it is incompatible with existing applications already
using the gs segment selector for other purposes.

Benchmarking various approaches for reading the current CPU number:

ARMv7 Processor rev 4 (v7l)
Machine model: Cubietruck
- Baseline (empty loop):                                    8.4 ns
- Read CPU from rseq cpu_id:                               16.7 ns
- Read CPU from rseq cpu_id (lazy register):               19.8 ns
- glibc 2.19-0ubuntu6.6 getcpu:                           301.8 ns
- getcpu system call:                                     234.9 ns

x86-64 Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz:
- Baseline (empty loop):                                    0.8 ns
- Read CPU from rseq cpu_id:                                0.8 ns
- Read CPU from rseq cpu_id (lazy register):                0.8 ns
- Read using gs segment selector:                           0.8 ns
- "lsl" inline assembly:                                   13.0 ns
- glibc 2.19-0ubuntu6 getcpu:                              16.6 ns
- getcpu system call:                                      53.9 ns

- Speed (benchmark taken on v8 of patchset)

Running 10 runs of hackbench -l 100000 seems to indicate, contrary to
expectations, that enabling CONFIG_RSEQ slightly accelerates the
scheduler:

Configuration: 2 sockets * 8-core Intel(R) Xeon(R) CPU E5-2630 v3 @
2.40GHz (directly on hardware, hyperthreading disabled in BIOS, energy
saving disabled in BIOS, turboboost disabled in BIOS, cpuidle.off=1
kernel parameter), with a Linux v4.6 defconfig+localyesconfig,
restartable sequences series applied.

* CONFIG_RSEQ=n

avg.:      41.37 s
std.dev.:   0.36 s

* CONFIG_RSEQ=y

avg.:      40.46 s
std.dev.:   0.33 s

- Size

On x86-64, between CONFIG_RSEQ=n/y, the text size increase of vmlinux is
567 bytes, and the data size increase of vmlinux is 5696 bytes.

Greg Kroah-Hartman be65f9ed26 staging: lustre: delete the filesystem from the tree.
The Lustre filesystem has been in the kernel tree for over 5 years now.
While it has been an endless source of enjoyment for new kernel
developers learning how to do basic codingstyle cleanups, as well as an
semi-entertaining source of bewilderment from the vfs developers any
time they have looked into the codebase to try to figure out how to port
their latest api changes to this filesystem, it has not really moved
forward into the "this is in shape to get out of staging" despite many
half-completed attempts.

And getting code out of staging is the main goal of that portion of the
kernel tree.  Code should not stagnate and it feels like having this
code in staging is only causing the development cycle of the filesystem
to take longer than it should.  There is a whole separate out-of-tree
copy of this codebase where the developers work on it, and then random
changes are thrown over the wall at staging at some later point in time.
This dual-tree development model has never worked, and the state of this
codebase is proof of that.

So, let's just delete the whole mess.  Now the lustre developers can go
off and work in their out-of-tree codebase and not have to worry about
providing valid changelog entries and breaking their patches up into
logical pieces.  They can take the time they have spend doing those
types of housekeeping chores and get the codebase into a much better
shape, and it can be submitted for inclusion into the real part of the
kernel tree when ready.

David S. Miller fd129f8941 Merge git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next
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.

Takashi Iwai d4d5a1cd29 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

Linus Torvalds 92400b8c8b Merge branch 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull locking updates from Ingo Molnar:

 - Lots of tidying up changes all across the map for Linux's formal
   memory/locking-model tooling, by Alan Stern, Akira Yokosawa, Andrea
   Parri, Paul E. McKenney and SeongJae Park.

   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)

 - misc smaller improvements, cleanups and fixes all across the locking
   subsystem

Jeff Kirsher says:

====================
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.

MAINTAINERS: Update Albert's email, he's back at Berkeley
When I was adding a MAINTAINERS entry for SiFive's drivers I realized
that Albert's email is out of date -- he's gone back to Berkeley, so his
SiFive email is technically defunct.  This patch updates his entry to a
current email address, hosted at Berkeley.

MAINTAINERS: Add myself as a maintainer for SiFive's drivers
There aren't actually any files in the tree that match these patterns
right now, but we've just started submitting our drivers so I thought it
would be good to make sure there's at least someone at SiFive who's
listed as maintaining them.  I'm leaving the RISC-V lists on here
because:

* As of today, all the RISC-V ASICs that people can actually buy are
  from SiFive -- though hopefully there'll be more soon!
* The RTL for many of our devices is open source, so I anticipate these
  devices might make they way chips from other vendors.
* We may standardize some of these devices as part of a RISC-V
  specification at some point in the future.

I'm a bit swamped right now so I might not be the most active maintainer
of these drivers, but I think it'd be good to make sure someone who has
hardware access gets CC'd on updates to our drivers just as a sanity
check.  Hopefully that's an OK way to handle this.

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.

Sridhar Samudrala 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.

Sridhar Samudrala 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.

Masahiro Yamada 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.

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.

Hans Verkuil 68afa17322 media: zoran: move to staging in preparation for removal
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.

S390 bpf_jit.S is removed in net-next and had changes in 'net',
since that code isn't used any more take the removal.

TLS data structures split the TX and RX components in 'net-next',
put the new struct members from the bug fix in 'net' into the RX
part.

The 'net-next' tree had some reworking of how the ERSPAN code works in
the GRE tunneling code, overlapping with a one-line headroom
calculation fix in 'net'.

Overlapping changes in __sock_map_ctx_update_elem(), keep the bits
that read the prog members via READ_ONCE() into local variables
before using them.

Christoph Hellwig 782e6769c0 dma-mapping: provide a generic dma-noncoherent implementation
Add a new dma_map_ops implementation that uses dma-direct for the
address mapping of streaming mappings, and which requires arch-specific
implemenations of coherent allocate/free.

Architectures have to provide flushing helpers to ownership trasnfers
to the device and/or CPU, and can provide optional implementations of
the coherent mmap functionality, and the cache_flush routines for
non-coherent long term allocations.
