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.

23221d997b arm64 updates for 4.17 
Nothing particularly stands out here, probably because people were tied
 up with spectre/meltdown stuff last time around. Still, the main pieces
 are:
 
 - Rework of our CPU features framework so that we can whitelist CPUs that
   don't require kpti even in a heterogeneous system
 
 - Support for the IDC/DIC architecture extensions, which allow us to elide
   instruction and data cache maintenance when writing out instructions
 
 - Removal of the large memory model which resulted in suboptimal codegen
   by the compiler and increased the use of literal pools, which could
   potentially be used as ROP gadgets since they are mapped as executable
 
 - Rework of forced signal delivery so that the siginfo_t is well-formed
   and handling of show_unhandled_signals is consolidated and made
   consistent between different fault types
 
 - More siginfo cleanup based on the initial patches from Eric Biederman
 
 - Workaround for Cortex-A55 erratum #1024718
 
 - Some small ACPI IORT updates and cleanups from Lorenzo Pieralisi
 
 - Misc cleanups and non-critical fixes

Pull time(r) updates from Thomas Gleixner:
 "A small set of updates for timers and timekeeping:

   - The most interesting change is the consolidation of clock MONOTONIC
     and clock BOOTTIME.

     Clock MONOTONIC behaves now exactly like clock BOOTTIME and does
     not longer ignore the time spent in suspend. A new clock
     MONOTONIC_ACTIVE is provived which behaves like clock MONOTONIC in
     kernels before this change. This allows applications to
     programmatically check for the clock MONOTONIC behaviour.

     As discussed in the review thread, this has the potential of
     breaking user space and we might have to revert this. Knock on wood
     that we can avoid that exercise.

   - Updates to the NTP mechanism to improve accuracy

   - A new kernel internal data structure to aid the ongoing Y2038 work.

   - Cleanups and simplifications of the clocksource code.

   - Make the alarmtimer code play nicely with debugobjects"

cc5ada7ca3 Mostly small changes, as usual. 
This does add an IPMI BMC server-side driver, to allow a Linux
 system to act as an IPMI controller.  That's the biggest change,
 but it is just a new driver that is fairly narrow in use.
 
 The other largish change is removing ACPI SPMI probe support,
 which should have never really been there in the beginning.

Pull ACPI updates from Rafael Wysocki:
 "These update the ACPICA code in the kernel to follow upstream revision
  20180313 which includes fixes related to the so-called module-level
  AML (mostly "if" type of statements outside of any methods) that
  should improve the handling of systems that load alternative SSDTs
  depending on the current configuration, for example, and event
  handling fixes related to disabling and enabling GPEs on system
  startup and on suspend/resume.

  Moreover, the ACPICA license boilerplate is replaced with SPDX license
  IDs which alone reduces the number of lines of ACPICA code in the
  kernel quite a bit.

  Also added is a new driver for the generic ACPI Time and Alarm Device
  (TAD). At the moment it only handles the most basic capabilities of
  the TAD, however.

  In addition to that the ACPI battery driver is improved to handle
  battery thresholds on ThinkPads, among other things, some bugs are
  fixed, a new backlight quirk is added and some documentation is
  updated.

642e7fd233 Merge branch 'syscalls-next' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux 
Pull removal of in-kernel calls to syscalls from Dominik Brodowski:
 "System calls are interaction points between userspace and the kernel.
  Therefore, system call functions such as sys_xyzzy() or
  compat_sys_xyzzy() should only be called from userspace via the
  syscall table, but not from elsewhere in the kernel.

  At least on 64-bit x86, it will likely be a hard requirement from
  v4.17 onwards to not call system call functions in the kernel: It is
  better to use use a different calling convention for system calls
  there, where struct pt_regs is decoded on-the-fly in a syscall wrapper
  which then hands processing over to the actual syscall function. This
  means that only those parameters which are actually needed for a
  specific syscall are passed on during syscall entry, instead of
  filling in six CPU registers with random user space content all the
  time (which may cause serious trouble down the call chain). Those
  x86-specific patches will be pushed through the x86 tree in the near
  future.

  Moreover, rules on how data may be accessed may differ between kernel
  data and user data. This is another reason why calling sys_xyzzy() is
  generally a bad idea, and -- at most -- acceptable in arch-specific
  code.

  This patchset removes all in-kernel calls to syscall functions in the
  kernel with the exception of arch/. On top of this, it cleans up the
  three places where many syscalls are referenced or prototyped, namely
  kernel/sys_ni.c, include/linux/syscalls.h and include/linux/compat.h"

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.

Pull perf updates from Ingo Molnar:
 "The main kernel side changes were:

   - Modernize the kprobe and uprobe creation/destruction tooling ABIs:

     The existing text based APIs (kprobe_events and uprobe_events in
     tracefs), are naive, limited ABIs in that they require user-space
     to clean up after themselves, which is both difficult and fragile
     if the tool is buggy or exits unexpectedly. In other words they are
     not really suited for modern, robust tooling.

     So introduce a modern, file descriptor based ABI that does not have
     these limitations: introduce the 'perf_kprobe' and 'perf_uprobe'
     PMUs and extend the perf_event_open() syscall to create events with
     a kprobe/uprobe attached to them. These [k,u]probe are associated
     with this file descriptor, so they are not available in tracefs.

     (Song Liu)

   - Intel Cannon Lake CPU support (Harry Pan)

   - Intel PT cleanups (Alexander Shishkin)

   - Improve the performance of pinned/flexible event groups by using RB
     trees (Alexey Budankov)

   - Add PERF_EVENT_IOC_MODIFY_ATTRIBUTES which allows the modification
     of hardware breakpoints, which new ABI variant massively speeds up
     existing tooling that uses hardware breakpoints to instrument (and
     debug) memory usage.

     (Milind Chabbi, Jiri Olsa)

   - Various Intel PEBS handling fixes and improvements, and other Intel
     PMU improvements (Kan Liang)

   - Various perf core improvements and optimizations (Peter Zijlstra)

   - ... misc cleanups, fixes and updates.

  There's over 200 tooling commits, here's an (imperfect) list of
  highlights:

   - 'perf annotate' improvements:

      * Recognize and handle jumps to other functions as calls, which
        improves the navigation along jumps and back. (Arnaldo Carvalho
        de Melo)

      * Add the 'P' hotkey in TUI annotation to dump annotation output
        into a file, to ease e-mail reporting of annotation details.
        (Arnaldo Carvalho de Melo)

      * Add an IPC/cycles column to the TUI (Jin Yao)

      * Improve s390 assembly annotation (Thomas Richter)

      * Refactor the output formatting logic to better separate it into
        interactive and non-interactive features and add the --stdio2
        output variant to demonstrate this. (Arnaldo Carvalho de Melo)

   - 'perf script' improvements:

      * Add Python 3 support (Jaroslav Škarvada)

      * Add --show-round-event (Jiri Olsa)

   - 'perf c2c' improvements:

      * Add NUMA analysis support (Jiri Olsa)

   - 'perf trace' improvements:

      * Improve PowerPC support (Ravi Bangoria)

   - 'perf inject' improvements:

      * Integrate ARM CoreSight traces (Robert Walker)

   - 'perf stat' improvements:

      * Add the --interval-count option (yuzhoujian)

      * Add the --timeout option (yuzhoujian)

   - 'perf sched' improvements (Changbin Du)

   - Vendor events improvements :

      * Add IBM s390 vendor events (Thomas Richter)

      * Add and improve arm64 vendor events (John Garry, Ganapatrao
        Kulkarni)

      * Update POWER9 vendor events (Sukadev Bhattiprolu)

   - PMU handling improvements (Agustin Vega-Frias)

   - Record machine topology in perf.data (Jiri Olsa)

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."

 "The main RCU subsystem changes in this cycle were:

  - Miscellaneous fixes, perhaps most notably removing obsolete code
    whose only purpose in life was to gather information for the
    now-removed RCU debugfs facility. Other notable changes include
    removing NO_HZ_FULL_ALL in favor of the nohz_full kernel boot
    parameter, minor optimizations for expedited grace periods, some
    added tracing, creating an RCU-specific workqueue using Tejun's new
    WQ_MEM_RECLAIM flag, and several cleanups to code and comments.

  - SRCU cleanups and optimizations.

  - Torture-test updates, perhaps most notably the adding of ARMv8
    support, but also including numerous cleanups and usability fixes"

3e67f106f6 inet: frags: break the 2GB limit for frags storage 
Some users are willing to provision huge amounts of memory to be able
to perform reassembly reasonnably well under pressure.

Current memory tracking is using one atomic_t and integers.

Switch to atomic_long_t so that 64bit arches can use more than 2GB,
without any cost for 32bit arches.

Note that this patch avoids an overflow error, if high_thresh was set
to ~2GB, since this test in inet_frag_alloc() was never true :

if (... || frag_mem_limit(nf) > nf->high_thresh)

Tested:

$ echo 16000000000 >/proc/sys/net/ipv4/ipfrag_high_thresh

<frag DDOS>

$ grep FRAG /proc/net/sockstat
FRAG: inuse 14705885 memory 16000002880

648700f76b inet: frags: use rhashtables for reassembly units 
Some applications still rely on IP fragmentation, and to be fair linux
reassembly unit is not working under any serious load.

It uses static hash tables of 1024 buckets, and up to 128 items per bucket (!!!)

A work queue is supposed to garbage collect items when host is under memory
pressure, and doing a hash rebuild, changing seed used in hash computations.

This work queue blocks softirqs for up to 25 ms when doing a hash rebuild,
occurring every 5 seconds if host is under fire.

Then there is the problem of sharing this hash table for all netns.

It is time to switch to rhashtables, and allocate one of them per netns
to speedup netns dismantle, since this is a critical metric these days.

Lookup is now using RCU. A followup patch will even remove
the refcount hold/release left from prior implementation and save
a couple of atomic operations.

Before this patch, 16 cpus (16 RX queue NIC) could not handle more
than 1 Mpps frags DDOS.

After the patch, I reach 9 Mpps without any tuning, and can use up to 2GB
of storage for the fragments (exact number depends on frags being evicted
after timeout)

$ grep FRAG /proc/net/sockstat
FRAG: inuse 1966916 memory 2140004608

A followup patch will change the limits for 64bit arches.

a5af1fb94f dt-bindings: net: meson-dwmac: add support for the Meson8m2 SoC 
The Meson8m2 SoC uses a similar (potentially even identical) register
layout for the dwmac glue as Meson8b and GXBB. Unfortunately there is no
documentation available.
Testing shows that both, RMII and RGMII PHYs are working if they are
configured as on Meson8b. Add a new compatible string to the
documentation so differences (if there are any) between Meson8m2 and the
other SoCs can be taken care of within the driver.
