Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next
Pull networking updates from David Miller:
1) New ipset extensions for matching on destination MAC addresses, from
Stefano Brivio.
2) Add ipv4 ttl and tos, plus ipv6 flow label and hop limit offloads to
nfp driver. From Stefano Brivio.
3) Implement GRO for plain UDP sockets, from Paolo Abeni.
4) Lots of work from Michał Mirosław to eliminate the VLAN_TAG_PRESENT
bit so that we could support the entire vlan_tci value.
5) Rework the IPSEC policy lookups to better optimize more usecases,
from Florian Westphal.
6) Infrastructure changes eliminating direct manipulation of SKB lists
wherever possible, and to always use the appropriate SKB list
helpers. This work is still ongoing...
7) Lots of PHY driver and state machine improvements and
simplifications, from Heiner Kallweit.
8) Various TSO deferral refinements, from Eric Dumazet.
9) Add ntuple filter support to aquantia driver, from Dmitry Bogdanov.
10) Batch dropping of XDP packets in tuntap, from Jason Wang.
11) Lots of cleanups and improvements to the r8169 driver from Heiner
Kallweit, including support for ->xmit_more. This driver has been
getting some much needed love since he started working on it.
12) Lots of new forwarding selftests from Petr Machata.
13) Enable VXLAN learning in mlxsw driver, from Ido Schimmel.
14) Packed ring support for virtio, from Tiwei Bie.
15) Add new Aquantia AQtion USB driver, from Dmitry Bezrukov.
16) Add XDP support to dpaa2-eth driver, from Ioana Ciocoi Radulescu.
17) Implement coalescing on TCP backlog queue, from Eric Dumazet.
18) Implement carrier change in tun driver, from Nicolas Dichtel.
19) Support msg_zerocopy in UDP, from Willem de Bruijn.
20) Significantly improve garbage collection of neighbor objects when
the table has many PERMANENT entries, from David Ahern.
21) Remove egdev usage from nfp and mlx5, and remove the facility
completely from the tree as it no longer has any users. From Oz
Shlomo and others.
22) Add a NETDEV_PRE_CHANGEADDR so that drivers can veto the change and
therefore abort the operation before the commit phase (which is the
NETDEV_CHANGEADDR event). From Petr Machata.
23) Add indirect call wrappers to avoid retpoline overhead, and use them
in the GRO code paths. From Paolo Abeni.
24) Add support for netlink FDB get operations, from Roopa Prabhu.
25) Support bloom filter in mlxsw driver, from Nir Dotan.
26) Add SKB extension infrastructure. This consolidates the handling of
the auxiliary SKB data used by IPSEC and bridge netfilter, and is
designed to support the needs to MPTCP which could be integrated in
the future.
27) Lots of XDP TX optimizations in mlx5 from Tariq Toukan.

The other patches from Alexey and Petr and trivial fixes that are adequately described in their respective subject lines. With this last pull request of the year, I want to thank everyone who has contributed patches, testing, and reviews to the SELinux project this year, and the past 18 years.

While most of them are re-gifts from others, unlike the typical re-gift, these are things you will want in and around your tree; I promise. This pull request is perhaps a bit larger than our typical PR, but most of it comes from Jan's rework of audit's fanotify code; a very welcome improvement. We ran this through our normal regression tests, as well as some newly created stress tests and everything looks good. Richard added a few patches, mostly cleaning up a few things and and shortening some of the audit records that we send to userspace; a change the userspace folks are quite happy about. Finally YueHaibing and I kick in a few patches to simplify things a bit and make the code less prone to errors.

powerpc updates for 4.21
Notable changes:
- Mitigations for Spectre v2 on some Freescale (NXP) CPUs.
- A large series adding support for pass-through of Nvidia V100 GPUs to guests
on Power9.
- Another large series to enable hardware assistance for TLB table walk on
MPC8xx CPUs.
- Some preparatory changes to our DMA code, to make way for further cleanups
from Christoph.
- Several fixes for our Transactional Memory handling discovered by fuzzing the
signal return path.
- Support for generating our system call table(s) from a text file like other
architectures.
- A fix to our page fault handler so that instead of generating a WARN_ON_ONCE,
user accesses of kernel addresses instead print a ratelimited and
appropriately scary warning.
- A cosmetic change to make our unhandled page fault messages more similar to
other arches and also more compact and informative.
- Freescale updates from Scott:
"Highlights include elimination of legacy clock bindings use from dts
files, an 83xx watchdog handler, fixes to old dts interrupt errors, and
some minor cleanup."
And many clean-ups, reworks and minor fixes etc.

similar to other arches and also more compact and informative.
- Freescale updates from Scott:
"Highlights include elimination of legacy clock bindings use from
dts files, an 83xx watchdog handler, fixes to old dts interrupt
errors, and some minor cleanup."
And many clean-ups, reworks and minor fixes etc.

sched/fair: Fix warning on non-SMP build
Caused by making the variable static:
kernel/sched/fair.c:119:21: warning: 'capacity_margin' defined but not used [-Wunused-variable]
Seems easiest to just move it up under the existing ifdef CONFIG_SMP
that's a few lines above.

Here's the main MIPS pull for Linux 4.21. Core architecture changes
include:
- Syscall tables & definitions for unistd.h are now generated by
scripts, providing greater consistency with other architectures &
making it easier to add new syscalls.
- Support for building kernels with no floating point support, upon
which any userland attempting to use floating point instructions will
receive a SIGILL. Mostly useful to shrink the kernel & as preparation
for nanoMIPS support which does not yet include FP.
- MIPS SIMD Architecture (MSA) vector register context is now exposed
by ptrace via a new NT_MIPS_MSA regset.
- ASIDs are now stored as 64b values even for MIPS32 kernels, expanding
the ASID version field sufficiently that we don't need to worry about
overflow & avoiding rare issues with reused ASIDs that have been
observed in the wild.
- The branch delay slot "emulation" page is now mapped without write
permission for the user, preventing its use as a nice location for
attacks to execute malicious code from.
- Support for ioremap_prot(), primarily to allow gdb or other
ptrace users the ability to view their tracee's memory using the same
cache coherency attribute.
- Optimizations to more cpu_has_* macros, allowing more to be
compile-time constant where possible.
- Enable building the whole kernel with UBSAN instrumentation.
- Enable building the kernel with link-time dead code & data
elimination.
Platform specific changes include:
- The Boston board gains a workaround for DMA prefetching issues with
the EG20T Platform Controller Hub that it uses.
- Cleanups to Cavium Octeon code removing about 20k lines of redundant
code, mostly unused or duplicate register definitions in headers.
- defconfig updates for the DECstation machines, including new
defconfigs for r4k & 64b machines.
- Further work on Loongson 3 support.
- DMA fixes for SiByte machines.

RISC-V Updates for the 4.21 Merge Window, Part 1
We don't have many patches for this merge window, probably because
everything has been a bit busy with the holidays and conferences. The
only big user-visible change is to move over to an SBI-based earlycon
instead of our arch-specific early printk support.
The only outstanding patch set I know of is the audit patch set, which
I've managed to make a mess of and will attempt to clean up.

asm-generic: syscall table script for arch/sh
I worked with Firoz Khan to change all architectures to have their system call tables (syscall.S and asm/unistd.h) generated by a script from a more readable input file the same way that we already had on x86, s390 and arm. I offered to take those conversions through the asm-generic tree that did not get picked up by the architecture maintainers, and fortunately all but one have now been accepted into arch maintainer trees, so this branch only contains the conversion for arch/sh/, with permission from Rich. The conversion does not include the old 64-bit sh5 architecture, which has never shipped and not even compiled in a long time. The table in include/uapi/asm/unistd.h is also not included here, as Firoz is still working on that one, it will have to wait for the next following merge window, hopefully together with the addition of the 64-bit time_t system calls for the y2038 work that led to the system call table rework.

arm64 festive updates for 4.21
In the end, we ended up with quite a lot more than I expected: - Support for ARMv8.3 Pointer Authentication in userspace (CRIU and kernel-side support to come later) - Support for per-thread stack canaries, pending an update to GCC that is currently undergoing review - Support for kexec_file_load(), which permits secure boot of a kexec payload but also happens to improve the performance of kexec dramatically because we can avoid the sucky purgatory code from userspace. Kdump will come later (requires updates to libfdt). - Optimisation of our dynamic CPU feature framework, so that all detected features are enabled via a single stop_machine() invocation - KPTI whitelisting of Cortex-A CPUs unaffected by Meltdown, so that they can benefit from global TLB entries when KASLR is not in use - 52-bit virtual addressing for userspace (kernel remains 48-bit) - Patch in LSE atomics for per-cpu atomic operations - Custom preempt.h implementation to avoid unconditional calls to preempt_schedule() from preempt_enable() - Support for the new 'SB' Speculation Barrier instruction - Vectorised implementation of XOR checksumming and CRC32 optimisations - Workaround for Cortex-A76 erratum #1165522 - Improved compatibility with Clang/LLD - Support for TX2 system PMUS for profiling the L3 cache and DMC - Reflect read-only permissions in the linear map by default - Ensure MMIO reads are ordered with subsequent calls to Xdelay() - Initial support for memory hotplug - Tweak the threshold when we invalidate the TLB by-ASID, so that mremap() performance is improved for ranges spanning multiple PMDs. - Minor refactoring and cleanups -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABCgAGBQJcE4TmAAoJELescNyEwWM0Nr0H/iaU7/wQSzHyNXtZoImyKTul Blu2ga4/EqUrTU7AVVfmkl/3NBILWlgQVpY6tH6EfXQuvnxqD7CizbHyLdyO+z0S B5PsFUH2GLMNAi48AUNqGqkgb2knFbg+T+9IimijDBkKg1G/KhQnRg6bXX32mLJv Une8oshUPBVJMsHN1AcQknzKariuoE3u0SgJ+eOZ9yA2ZwKxP4yy1SkDt3xQrtI0 lojeRjxcyjTP1oGRNZC+BWUtGOT35p7y6cGTnBd/4TlqBGz5wVAJUcdoxnZ6JYVR O8+ob9zU+4I0+SKt80s7pTLqQiL9rxkKZ5joWK1pr1g9e0s5N5yoETXKFHgJYP8= =sYdt -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 festive updates from Will Deacon: "In the end, we ended up with quite a lot more than I expected: - Support for ARMv8.3 Pointer Authentication in userspace (CRIU and kernel-side support to come later) - Support for per-thread stack canaries, pending an update to GCC that is currently undergoing review - Support for kexec_file_load(), which permits secure boot of a kexec payload but also happens to improve the performance of kexec dramatically because we can avoid the sucky purgatory code from userspace.

Pull irq updates from Thomas Gleixner:
"The interrupt department provides:
Core updates:
- Better spreading to NUMA nodes in the affinity management
- Support for more than one set of interrupts to spread out to allow
separate queues for separate functionality of a single device.
- Decouple the non queue interrupts from being managed. Those are
usually general interrupts for error handling etc. and those should
never be shut down. This also a preparation to utilize the
spreading mechanism for initial spreading of non-managed interrupts
later.
- Make the single CPU target selection in the matrix allocator more
balanced so interrupts won't accumulate on single CPUs in certain
situations.
- A large spell checking patch so we don't end up fixing single typos
over and over.
Driver updates:
- A bunch of new irqchip drivers (RDA8810PL, Madera, imx-irqsteer)
- Updates for the 8MQ, F1C100s platform drivers

Device properties framework updates for 4.21-rc1
- Introduce "software nodes", analogous to the DT and ACPI firmware
nodes except that they can be created by kernel code, in order to
complement fwnodes representing real firmware nodes when they are
incomplete (for example missing device properties) and to supply
the primary fwnode when the firmware lacks hardware description
for a device completely, and replace the "property_set" struct
fwnode_handle type with software nodes (Heikki Krogerus).
- Clean up the just introduced software nodes support and fix a commet
in the graph-handling code (Colin Ian King, Marco Felsch).

This round is dominated by NXP's i.MX clk drivers. We gained support for two or
three i.MX SoCs in here and that mostly means a lot of driver code and data.
Beyond that platform, there are some new Mediatek, Amlogic, and Qualcomm clk
drivers added in here, and then we get to the long tail of driver updates and
non-critical fixes all around, including code for vendors such as Renesas,
Rockchip, Nvidia, and Allwinner. Overall, the driver updates look normal.
Beyond the usual driver updates we have an update to make registering OF based
clk providers a little simpler when they're devices created as a child of a
device backed by a node in DT. Drivers don't have to jump through hoops to
unregister the provider upon driver removal anymore because the API does the
right thing and uses the parent device DT node.
Core:
- Make devm_of_clk_add_hw_provider() use parent dt node if necessary
- Various SPDX taggings
- Mark clk_ops const when possible
New Drivers:
- NXP i.MX7ULP SoC clock support
- NXP i.MX8QXP SoC clock support
- NXP i.MX8MQ SoC clock support
- NXP QorIQ T1023 SoC support
- Qualcomm SDM845 audio subsystem clks
- Qualcomm SDM845 GPU clck controllers
- Qualcomm QCS404 RPM clk support
- Mediatek MT7629 SoC clk controllers
- Allwinner F1c100s SoC clocks
- Allwinner H6 display engine clocks
- Amlogic GX video clocks
- Support for Amlogic meson8b CPU frequency scaling
- Amlogic Meson8b CPU post-divider clocks
Updates:
- Proper suspend/resume on VersaClock5
- Shrink code some with DEFINE_SHOW_ATTRIBUTE()
- Register fixes for Rockchip rk3188 and rk3328
- One new critical clock for Rockchip rk3188 and a fixed clock id (double used number)
- New clock id for Rockchip rk3328
- Amlogic Meson8/Meson8b video clock support
- Amlogic got a clk-input helper and used it for the axg-audio clock driver
- Sigma Delta modulation for the Allwinner A33 audio clocks
- Support for CPEX (timer) clocks on various Renesas R-Car Gen3 and RZ/G2 SoCs
- Support for SDHI HS400 clocks on early revisions of Renesas R-Car H3 and M3-W
- Support for SDHI and USB clocks on Renesas RZ/A2
- Support for RPC (SPI Multi I/O Bus Controller) clocks on Renesas R-Car V3M
- Qualcomm MSM8998 GCC driver improvements (resets, drop unused clks, etc.)

regmap: Updates for v4.21
This has been a busy release for the regmap-irq code, there's several
new features been added, including an API cleanup for how we specify
types that affected one existing driver (gpio-max77620):
- Support for hardware that flags rising and falling edges on separate
status bits from Bartosz Golaszewski.
- Support for explicitly clearing interrupts before unmasking from
Bartosz Golaszewski.
- Support for level triggered IRQs from Matti Vaittinen.

spi: Updates for v4.21
The main thing this release has been a lot of work on the integration
with SPI NOR flashes, there's been some specific support for a while for
controller features designed to make them perform better but it's not
worked out as well as hoped so the interface has been redesigned in a
way that will hopefully do better - it's already been adopted by a
number of additional controllers so things are looking good. Otherwise
most of the work has been driver specific:
- Support for better integration with NOR flashes from Boris Brezillon
and Yogesh Narayan Gaur plus usage of it in several drivers.
- A big cleanup of the Rockchip driver from Emil Renner Berthing.
- Lots of performance improvements for bcm2835 from Lukas Wunner.
- Slave mode support for pxa2xx from Lubomir Rintel.
- Support for Macronix MXIC, Mediatek MT7629 and MT8183, NPCM PSPI,
and Renesas r8a77470.

regulator: Updates for v4.20
This has been a very busy release for the core, some fixes, one large new
feature and a big bit of refactoring to update the GPIO API:
- Support for coupled regulators from Dmitry Osipenko based on a prior
attempt by Maciej Purski, allowing us to handle situations where the
voltages on two regulators can't be too far apart from each other.
- Conversion of the GPIO support in both drivers and the core to use
GPIO descriptors rather than numbers, part of the overall project to
remove GPIO numbers.
- Support for standby mode suspend states from Andrei Stefanescu.
- New drivers for Allwinner AXP209, Cirrus Logic Lochnagar and
Microchip MPC16502.

pwm: Changes for v4.21-rc1
Not a lot going on this cycle. There's some more cleanup going on and new driver support that was not quite ready in time for v4.21-rc1, but here are a few fixes and improvements that are good to go. The Kona PWM driver can now be built on the Cygnus architecture and the i.MX driver gained support for hardware readback. Some small fixes are provided for the clks711x and lpc18xx-sct drivers. Finally, to round things off some drivers are switched to SPDX license identifiers. -----BEGIN PGP SIGNATURE----- iQJNBAABCAA3FiEEiOrDCAFJzPfAjcif3SOs138+s6EFAlwgvusZHHRoaWVycnku cmVkaW5nQGdtYWlsLmNvbQAKCRDdI6zXfz6zobXWEACgOF26QUs/Vt6n7r7XRXeL rHZwhJ44+0/wHm6MNJcj8jy7Ct0iJVBhxyK4680A0n2u1T6SxA0YZu2yVC46iNFc 52bipsZ3U8uuKHBvWhGxmYXknj1nJqKPg2yAxyJ4dD6LlJaGYJKaxZe4BH/gZ4qI WaYH88rcopfcVcrzl57IPoibiEwfN1V2WAvGkKihj1y1KN65mbUHgRFAqAA2s0u/ qdpGpqIrBEHeOZSoKuNDEADkO5xiHpO+uEcxY2xeWg0onP/X+tVHerkG28+ruwP/ PWXI3uEe9SAeEzf3YKNqCNWLLRVQ/+JU6oS6qwMjhgV5w+HppIMIUJUo1hddofL0 RvTZ3IhTpGXGCYpp1OuF51ZWZpTb56VZ4roHt20bjaYLqA6SEu0AszxELVvOYO+B kBVMwohtNYeZpuM2eGOdvZAMG55cicRa55MZzpCDMNfJZSr0CrVwnX6o5MKTuozA B21wxm9PPR/miPBmGnFegXmuqB+Uf/uWqXeGfWwwdlfS4dchOb8pBxDoO5P53Dx6 xOnfWQu0Ol1sUVLXg9l0rEJAHx1F3SncrE4WWnV+pK1NkMoz9+Ry5aVqIBOFI+Qw ImEssuM52sv93S9HXuNq6DOUwoOSwkE4HSjPneKmAA1XMQ846YB/zj2R0Ki+dZAK Zlk9HVwIOKpP0gG0tcPBOA== =ni7n -----END PGP SIGNATURE----- Merge tag 'pwm/for-4.21-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm Pull pwm updates from Thierry Reding: "Not a lot going on this cycle.

Power management updates for 4.21-rc1
- Add sysadmin documentation for cpuidle (Rafael Wysocki).
- Make it possible to specify a cpuidle governor from kernel
command line, add new cpuidle state sysfs attributes for
governor evaluation, and improve the "polling" idle state
handling (Rafael Wysocki).
- Fix the handling of the "required-opps" DT property in the
operating performance points (OPP) framework, improve the
integration of it with the generic power domains (genpd)
framework, improve the handling of performance states in
them and clean up the idle states vs performance states
separation in genpd (Viresh Kumar, Ulf Hansson).
- Add a cpufreq driver called "qcom-hw" for Qualcomm SoCs using
a hardware engine to control CPU frequency transitions along
with DT bindings for it (Taniya Das).
- Fix an intel_pstate driver issue related to CPU offline and
update the documentation of it (Srinivas Pandruvada).
- Clean up the imx6q cpufreq driver (Anson Huang).
- Add SPDX license IDs to cpufreq schedutil governor files (Daniel
Lezcano).
- Switch over the runtime PM framework to using high-res timers
for device autosuspend to allow the control of it to be more
precise (Vincent Guittot).
- Disable non-wakeup ACPI GPEs during suspend-to-idle so that they
don't prevent the system from reaching the target low-power state
and simplify the suspend-to-idle handling on ACPI platforms
without full Low-Power S0 Idle (LPS0) support (Rafael Wysocki).
- Add system-wide suspend and resume support to the devfreq
framework (Lukasz Luba).
- Clean up the SmartReflex adaptive voltage scaling (AVS) driver and
add an SPDX license ID to it (Nishanth Menon, Uwe Kleine-König,
Thomas Meyer).
- Get rid of code duplication by using the DEFINE_SHOW_ATTRIBUTE
