38047d5c26 Driver core patches for 4.17-rc1
Here is the "big" set of driver core patches for 4.17-rc1.
 
 There's really not much here, just a bunch of firmware code refactoring
 from Luis as he attempts to wrangle that codebase into something that is
 managable, along with a bunch of userspace tests for it.  Other than
 that, a handful of small bugfixes and reverts of things that didn't work
 out.
 
 Full details are in the shortlog, it's not all that much.
 
 All of these have been in linux-next for a while with no reported
 issues.

df34df483a Staging/IIO patches for 4.17-rc1
Here is the big set of Staging/IIO driver patches for 4.17-rc1.
 
 It is a lot, over 500 changes, but not huge by previous kernel release
 standards.  We deleted more lines than we added again (27k added vs. 91k
 remvoed), thanks to finally being able to delete the IRDA drivers and
 networking code.
 
 We also deleted the ccree crypto driver, but that's coming back in
 through the crypto tree to you, in a much cleaned-up form.
 
 Added this round is at lot of "mt7621" device support, which is for an
 embedded device that Neil Brown cares about, and of course a handful of
 new IIO drivers as well.
 
 And finally, the fsl-mc core code moved out of the staging tree to the
 "real" part of the kernel, which is nice to see happen as well.
 
 Full details are in the shortlog, which has all of the tiny cleanup
 patches described.
 
 All of these have been in linux-next for a while with no reported
 issues.

ac9053d2dc USB/PHY patches for 4.17-rc1
Here is the big set of USB and PHY driver patches for 4.17-rc1.
 
 Lots of USB typeC work happened this round, with code moving from the
 staging directory into the "real" part of the kernel, as well as new
 infrastructure being added to be able to handle the different types of
 "roles" that typeC requires.
 
 There is also the normal huge set of USB gadget controller and driver
 updates, along with XHCI changes, and a raft of other tiny fixes all
 over the USB tree.  And the PHY driver updates are merged in here as
 well as they interacted with the USB drivers in some places.

A quiet release for SPI, some fixes and small updates for individual
 drivers with one bigger change from Linus Walleij which coverts the
 bitbanging SPI driver to use the GPIO descriptor API from Linus Walleij.
 Since GPIO descriptors were used by platform data this means there's a
 few changes in arch/ making relevant updates for a few platforms and one
 misc driver that are affected.

f5a8eb632b arch: remove obsolete architecture ports
This removes the entire architecture code for blackfin, cris, frv, m32r,
 metag, mn10300, score, and tile, including the associated device drivers.
 
 I have been working with the (former) maintainers for each one to ensure
 that my interpretation was right and the code is definitely unused in
 mainline kernels. Many had fond memories of working on the respective
 ports to start with and getting them included in upstream, but also saw
 no point in keeping the port alive without any users.
 
 In the end, it seems that while the eight architectures are extremely
 different, they all suffered the same fate: There was one company
 in charge of an SoC line, a CPU microarchitecture and a software
 ecosystem, which was more costly than licensing newer off-the-shelf
 CPU cores from a third party (typically ARM, MIPS, or RISC-V). It seems
 that all the SoC product lines are still around, but have not used the
 custom CPU architectures for several years at this point. In contrast,
 CPU instruction sets that remain popular and have actively maintained
 kernel ports tend to all be used across multiple licensees.
 
 The removal came out of a discussion that is now documented at
 https://lwn.net/Articles/748074/. Unlike the original plans, I'm not
 marking any ports as deprecated but remove them all at once after I made
 sure that they are all unused. Some architectures (notably tile, mn10300,
 and blackfin) are still being shipped in products with old kernels,
 but those products will never be updated to newer kernel releases.
 
 After this series, we still have a few architectures without mainline
 gcc support:
 
 - unicore32 and hexagon both have very outdated gcc releases, but the
   maintainers promised to work on providing something newer. At least
   in case of hexagon, this will only be llvm, not gcc.
 
 - openrisc, risc-v and nds32 are still in the process of finishing their
   support or getting it added to mainline gcc in the first place.
   They all have patched gcc-7.3 ports that work to some degree, but
   complete upstream support won't happen before gcc-8.1. Csky posted
   their first kernel patch set last week, their situation will be similar.

701f3b3149 Merge branch 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull locking updates from Ingo Molnar:
 "The main changes in the locking subsystem in this cycle were:

   - Add the Linux Kernel Memory Consistency Model (LKMM) subsystem,
     which is an an array of tools in tools/memory-model/ that formally
     describe the Linux memory coherency model (a.k.a.
     Documentation/memory-barriers.txt), and also produce 'litmus tests'
     in form of kernel code which can be directly executed and tested.

     Here's a high level background article about an earlier version of
     this work on LWN.net:

        https://lwn.net/Articles/718628/

     The design principles:

      "There is reason to believe that Documentation/memory-barriers.txt
       could use some help, and a major purpose of this patch is to
       provide that help in the form of a design-time tool that can
       produce all valid executions of a small fragment of concurrent
       Linux-kernel code, which is called a "litmus test". This tool's
       functionality is roughly similar to a full state-space search.
       Please note that this is a design-time tool, not useful for
       regression testing. However, we hope that the underlying
       Linux-kernel memory model will be incorporated into other tools
       capable of analyzing large bodies of code for regression-testing
       purposes."

     [...]

      "A second tool is klitmus7, which converts litmus tests to
       loadable kernel modules for direct testing. As with herd7, the
       klitmus7 code is freely available from

         http://diy.inria.fr/sources/index.html

       (and via "git" at https://github.com/herd/herdtools7)"

     [...]

     Credits go to:

      "This patch was the result of a most excellent collaboration
       founded by Jade Alglave and also including Alan Stern, Andrea
       Parri, and Luc Maranget."

     ... and to the gents listed in the MAINTAINERS entry:

18bd49043c MAINTAINERS: demote ARM port to "odd fixes"
As of the start of 2018, I am no longer paid to support the core 32-bit
ARM architecture code.  This means that this code is no longer
commercially supported, and is now only supported through voluntary
effort.

I will continue to merge patches as and when able, but this will be at a
lower priority than before (which means a longer latency.) I have also
be scaled back the amount of time spent reading email, so email that is
intended for my attention needs to make itself plainly obvious, or I
will miss it.

In an attempt to reduce the amount of email Cc'd to me, exclude
arch/arm/boot/dts from the maintainers patterns, but add entries for the
SolidRun platforms I look after.

03fe2debbb Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Fun set of conflict resolutions here...

For the mac80211 stuff, these were fortunately just parallel
adds.  Trivially resolved.

In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the
function phy_disable_interrupts() earlier in the file, whilst in
'net-next' the phy_error() call from this function was removed.

In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the
'rt_table_id' member of rtable collided with a bug fix in 'net' that
added a new struct member "rt_mtu_locked" which needs to be copied
over here.

The mlxsw driver conflict consisted of net-next separating
the span code and definitions into separate files, whilst
a 'net' bug fix made some changes to that moved code.

The mlx5 infiniband conflict resolution was quite non-trivial,
the RDMA tree's merge commit was used as a guide here, and
here are their notes:

====================

    Due to bug fixes found by the syzkaller bot and taken into the for-rc
    branch after development for the 4.17 merge window had already started
    being taken into the for-next branch, there were fairly non-trivial
    merge issues that would need to be resolved between the for-rc branch
    and the for-next branch.  This merge resolves those conflicts and
    provides a unified base upon which ongoing development for 4.17 can
    be based.

    Conflicts:
            drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f95
            (IB/mlx5: Fix cleanup order on unload) added to for-rc and
            commit b5ca15ad7e (IB/mlx5: Add proper representors support)
            add as part of the devel cycle both needed to modify the
            init/de-init functions used by mlx5.  To support the new
            representors, the new functions added by the cleanup patch
            needed to be made non-static, and the init/de-init list
            added by the representors patch needed to be modified to
            match the init/de-init list changes made by the cleanup
            patch.
    Updates:
            drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function
            prototypes added by representors patch to reflect new function
            names as changed by cleanup patch
            drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init
            stage list to match new order from cleanup patch

f6fb9ec02b usb: roles: Add Intel xHCI USB role switch driver
Various Intel SoCs (Cherry Trail, Broxton and others) have an internal USB
role switch for swiching the OTG USB data lines between the xHCI host
controller and the dwc3 gadget controller.

Note on some Cherry Trail systems there is ACPI/AML code listening to
edge interrupts on the id-pin (through an _AIE ACPI method) and switching
the role between ROLE_HOST and ROLE_NONE based on the id-pin. Note it does
not set the role to ROLE_DEVICE, because device-mode is usually not used
under Windows.

The presence of AML code which modifies the cfg0 reg (on some systems)
means that our read/write/modify of cfg0 may race with the AML code
doing the same to avoid this we take the global ACPI lock while doing
the read/write/modify.

Pull percpu fixes from Tejun Heo:
 "Late percpu pull request for v4.16-rc6.

   - percpu allocator pool replenishing no longer triggers OOM or
     warning messages.

     Also, the alloc interface now understands __GFP_NORETRY and
     __GFP_NOWARN. This is to allow avoiding OOMs from userland
     triggered actions like bpf map creation.

     Also added cond_resched() in alloc loop.

   - perpcu allocation now can be interrupted by kill sigs to avoid
     deadlocking OOM killer.

   - Added Dennis Zhou as a co-maintainer.

     He has rewritten the area map allocator, understands most of the
     code base and has been responsive for all bug reports"

c690eddc2f CRIS: Drop support for the CRIS port
The port was added back in 2000 so it's no longer even a good source
of inspiration for newer ports (if it ever was)

The last SoC (ARTPEC-3) with a CRIS main CPU was launched in 2008.

Coupled with time and working developer board hardware being
in low supply, it's time to drop the port from Linux.

So long and thanks for all the fish!

bb9d812643 arch: remove tile port
The Tile architecture port was added by Chris Metcalf in 2010, and
maintained until early 2018 when he orphaned it due to his departure
from Mellanox, and nobody else stepped up to maintain it. The product
line is still around in the form of the BlueField SoC, but no longer
uses the Tile architecture.

There are also still products for sale with Tile-GX SoCs, notably the
Mikrotik CCR router family. The products all use old (linux-3.3) kernels
with lots of patches and won't be upgraded by their manufacturers. There
have been efforts to port both OpenWRT and Debian to these, but both
projects have stalled and are very unlikely to be continued in the future.

Given that we are reasonably sure that nobody is still using the port
with an upstream kernel any more, it seems better to remove it now while
the port is in a good shape than to let it bitrot for a few years first.

4ba66a9760 arch: remove blackfin port
The Analog Devices Blackfin port was added in 2007 and was rather
active for a while, but all work on it has come to a standstill
over time, as Analog have changed their product line-up.

Aaron Wu confirmed that the architecture port is no longer relevant,
and multiple people suggested removing blackfin independently because
of some of its oddities like a non-working SMP port, and the amount of
duplication between the chip variants, which cause extra work when
doing cross-architecture changes.
