Pull powerpc updates from Michael Ellerman:
"Notable changes:
- Support for 4PB user address space on 64-bit, opt-in via mmap().
- Removal of POWER4 support, which was accidentally broken in 2016
and no one noticed, and blocked use of some modern instructions.
- Workarounds so that the hypervisor can enable Transactional Memory
on Power9.
- A series to disable the DAWR (Data Address Watchpoint Register) on
Power9.
- More information displayed in the meltdown/spectre_v1/v2 sysfs
files.
- A vpermxor (Power8 Altivec) implementation for the raid6 Q
Syndrome.
- A big series to make the allocation of our pacas (per cpu area),
kernel page tables, and per-cpu stacks NUMA aware when using the
Radix MMU on Power9.
And as usual many fixes, reworks and cleanups.

Pull kselftest update from Shuah Khan:
"This Kselftest update for 4.17-rc1 consists of:
- Test build error fixes
- Fixes to prevent intel_pstate from building on non-x86 systems.
- New test for ion with vgem driver.
- Change to print the test name to /dev/kmsg to add context to kernel
failures if any uncovered from running the test.
- Kselftest framework enhancements to add KSFT_TAP_LEVEL environment
variable to prevent nested TAP headers being printed in the
Kselftest output.
Nested TAP13 headers could cause problems for some parsers. This
change suppresses the nested headers from test programs and test
shell scripts with changes to framework and Makefiles without
changing the tests"

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.17 kernel cycle:
New drivers:
- Nintendo Wii GameCube GPIO, known as "Hollywood"
- Raspberry Pi mailbox service GPIO expander
- Spreadtrum main SC9860 SoC and IEC GPIO controllers.
Improvements:
- Implemented .get_multiple() callback for most of the
high-performance industrial GPIO cards for the ISA bus.
- ISA GPIO drivers now select the ISA_BUS_API instead of depending on
it. This is merged with the same pattern for all the ISA drivers
and some other Kconfig cleanups related to this.
Cleanup:
- Delete the TZ1090 GPIO drivers following the deletion of this SoC
from the ARM tree.
- Move the documentation over to driver-api to conform with the rest
of the kernel documentation build.
- Continue to make the GPIO drivers include only
<linux/gpio/driver.h> and not the too broad <linux/gpio.h> that we
want to get rid of.
- Managed to remove VLA allocation from two drivers pending more
fixes in this area for the next merge window.
- Misc janitorial fixes"

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.
Specifics:
- Update the in-kernel ACPICA code to upstream revision 20180313
including:
* Module-level AML code handling fixes and simplifications (Bob
Moore, Erik Schmauss).
* Fixes and cleanups related to messaging (Bob Moore).
* Events handling fixes related to disabling and enabling GPEs
(Erik Schmauss).
* Introduction of SPDX license identifiers and removal of license
boilerplate in multiple files (Erik Schmauss).
* Assorted fixes and cleanups (Bob Moore, Erik Schmauss, Hans de
Goede, Seunghun Han).
- Add new basic driver for the ACPI Time and Alarm Device (Rafael
Wysocki).
- Modify the ACPI battery driver to support battery thresholds on
Lenovo ThinkPads (Ognjen Galic, Colin Ian King).
- Avoid reporting battery capacity over 100 in the ACPI battery
driver in some cases (Laszlo Toth).
- Make the kernel recognize an OEM _OSI string from Dell to avoid
power management issues with NVidia GPUs in Dell platforms (Alex
Hung).
- Make the PCI IRQ management code handle missing _PRS cleanly (Alex
Hung).
- Fix uevent notifications related to device hotplut (Lee, Chun-Yi).
- Prevent the ACPI PAD driver from leaking memory (Lenny Szubowicz).
- Update the ACPI CPPC library code to include subspace IDs in the
kernel messages logged by it (George Cherian).
- Add backlight quirk for Samsung 670Z5E (Hans de Goede).
- Add the NFIT and HMAT tables to the list of ACPI tables that can be
overridden via initrd (Dan Williams).
- Fix and clean up some ACPI documentation and Kconfig help language
(Aishwarya Pant, Randy Dunlap).
- Replace license boilerplate with an SPDX license ID in the ACPI
PMIC operation region handling code (Rajmohan Mani)"

The recent commit 15a3204d24a3 ("powerpc/64s: Set assembler machine
type to POWER4") set the machine type in our ASFLAGS when building the
kernel, and removed some ".machine power4" directives from various asm
files.
This broke the selftests build on old toolchains (that don't assume
Power4), because we build the kernel source files into the selftests
using different ASFLAGS.
The fix is simply to add -mpower4 to the selftest ASFLAGS as well.

Pul removal of obsolete architecture ports from Arnd Bergmann:
"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.
[ See the new nds32 port merged in the previous commit for the next
generation of "one company in charge of an SoC line, a CPU
microarchitecture and a software ecosystem" - Linus ]
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
[ Palmer Dabbelt points out that RISC-V support is in mainline gcc
since gcc-7, although gcc-7.3.0 is the recommended minimum - Linus ]"

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)
- Intel PT tooling improvements (Adrian Hunter)
- PMU handling improvements (Agustin Vega-Frias)
- Record machine topology in perf.data (Jiri Olsa)

Ensure that ARCH is defined and that this only builds for
x86 architectures.
It is possible to build from the root of the Linux tree, which
will define ARCH, or to run make from the selftests/ directory
itself, which has no provision for defining ARCH, so this
change is to use the current definition (if any), or to check
uname -m if undefined.

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)"
[...]

founded by Jade Alglave and also including Alan Stern, Andrea
Parri, and Luc Maranget."

Daniel Borkmann says:
====================
pull-request: bpf-next 2018-03-31
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add raw BPF tracepoint API in order to have a BPF program type that
can access kernel internal arguments of the tracepoints in their
raw form similar to kprobes based BPF programs. This infrastructure
also adds a new BPF_RAW_TRACEPOINT_OPEN command to BPF syscall which
returns an anon-inode backed fd for the tracepoint object that allows
for automatic detach of the BPF program resp. unregistering of the
tracepoint probe on fd release, from Alexei.
2) Add new BPF cgroup hooks at bind() and connect() entry in order to
allow BPF programs to reject, inspect or modify user space passed
struct sockaddr, and as well a hook at post bind time once the port
has been allocated. They are used in FB's container management engine
for implementing policy, replacing fragile LD_PRELOAD wrapper
intercepting bind() and connect() calls that only works in limited
scenarios like glibc based apps but not for other runtimes in
containerized applications, from Andrey.
3) BPF_F_INGRESS flag support has been added to sockmap programs for
their redirect helper call bringing it in line with cls_bpf based
programs. Support is added for both variants of sockmap programs,
meaning for tx ULP hooks as well as recv skb hooks, from John.
4) Various improvements on BPF side for the nfp driver, besides others
this work adds BPF map update and delete helper call support from
the datapath, JITing of 32 and 64 bit XADD instructions as well as
offload support of bpf_get_prandom_u32() call. Initial implementation
of nfp packet cache has been tackled that optimizes memory access
(see merge commit for further details), from Jakub and Jiong.
5) Removal of struct bpf_verifier_env argument from the print_bpf_insn()
API has been done in order to prepare to use print_bpf_insn() soon
out of perf tool directly. This makes the print_bpf_insn() API more
generic and pushes the env into private data. bpftool is adjusted
as well with the print_bpf_insn() argument removal, from Jiri.
6) Couple of cleanups and prep work for the upcoming BTF (BPF Type
Format). The latter will reuse the current BPF verifier log as
well, thus bpf_verifier_log() is further generalized, from Martin.
7) For bpf_getsockopt() and bpf_setsockopt() helpers, IPv4 IP_TOS read
and write support has been added in similar fashion to existing
IPv6 IPV6_TCLASS socket option we already have, from Nikita.
8) Fixes in recent sockmap scatterlist API usage, which did not use
sg_init_table() for initialization thus triggering a BUG_ON() in
scatterlist API when CONFIG_DEBUG_SG was enabled. This adds and
uses a small helper sg_init_marker() to properly handle the affected
cases, from Prashant.
9) Let the BPF core follow IDR code convention and therefore use the
idr_preload() and idr_preload_end() helpers, which would also help
idr_alloc_cyclic() under GFP_ATOMIC to better succeed under memory
pressure, from Shaohua.
10) Last but not least, a spelling fix in an error message for the
BPF cookie UID helper under BPF sample code, from Colin.
