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.

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.

Pull selinux patches from Paul Moore:
 "I already used my best holiday pull request lines in the audit pull
  request, so this one is going to be a bit more boring, sorry about
  that. To make up for this, we do have a birthday of sorts to
  celebrate: SELinux turns 18 years old this December. Perhaps not the
  most exciting thing in the world for most people, but I think it's
  safe to say that anyone reading this email doesn't exactly fall into
  the "most people" category.

  Back to business and the pull request itself:

  Ondrej has five patches in this pull request and I lump them into
  three categories: one patch to always allow submounts (using similar
  logic to elsewhere in the kernel), one to fix some issues with the
  SELinux policydb, and the others to cleanup and improve the SELinux
  sidtab.

  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. Like any good open source effort,
  SELinux is only as good as the community which supports it, and I'm
  very happy that we have the community we do - thank you all!"

8d6973327e 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.

 - The generalization of the RDT code to accommodate the addition of

   This entails a subsystem move into a separate and generic

89261c5702 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.

5694cecdb0 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

 "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.

1fbb2dc6f0 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.)

Pull clk updates from Stephen Boyd:
 "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.

  Apart from 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.

  Summary:

  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)"

0051db8218 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.

79f20778fb 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

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.

8e61e7b5c4 sound updates for 4.21 
There are no intensive changes in both ALSA and ASoC core parts while
 rather most of changes are a bunch of driver fixes and updates.
 A large diff pattern appears in ASoC TI part which now merges both
 OMAP and DaVinci stuff, but the rest spreads allover the places.
 
 Note that this pull request includes also some updates for LED trigger
 and platform drivers for mute LEDs, appearing in the diffstat as well.
 
 Some highlights:
 
 ASoC:
 - Preparatory work for merging the audio-graph and audio-graph-scu
   cards
 - A merge of TI OMAP and DaVinci directories, as both product lines
   get merged together.  Also including a few architecture changes as
   well.
 - Major cleanups of the Maxim MAX9867 driver
 - Small fixes for tablets & co with Intel BYT/CHT chips
 - Lots of rsnd updates as usual
 - Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with
   RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx I2S
   controllers
 
 HD-audio:
 - Introduce audio-mute LED trigger for replacing the former hackish
   dynamic binding
 - Huawei WMI hotkey and mute LED support
 - Refactoring of PM code and display power controls
 - Headset button support in the generic jack code
 - A few updates for Tegra
 - Fixups for HP EliteBook and ASUS UX391UA
 - Lots of updates for Intel ASoC HD-audio, including the improved DSP
   detection and the fallback binding from ASoC SST to legacy HD-audio
   controller drivers
 
 Others:
 - Updates for FireWire TASCAM and Fireface devices, some other fixes
 - A few potential Spectre v1 fixes that are all trivial

c79b411eaa crypto: skcipher - remove remnants of internal IV generators 
Remove dead code related to internal IV generators, which are no longer
used since they've been replaced with the "seqiv" and "echainiv"
templates.  The removed code includes:

- The "givcipher" (GIVCIPHER) algorithm type.  No algorithms are
  registered with this type anymore, so it's unneeded.

- The "const char *geniv" member of aead_alg, ablkcipher_alg, and
  blkcipher_alg.  A few algorithms still set this, but it isn't used
  anymore except to show via /proc/crypto and CRYPTO_MSG_GETALG.
  Just hardcode "<default>" or "<none>" in those cases.

- The 'skcipher_givcrypt_request' structure, which is never used.

a4e92ce8e4 powerpc/fadump: Reservationless firmware assisted dump 
One of the primary issues with Firmware Assisted Dump (fadump) on Power
is that it needs a large amount of memory to be reserved. On large
systems with TeraBytes of memory, this reservation can be quite
significant.

In some cases, fadump fails if the memory reserved is insufficient, or
if the reserved memory was DLPAR hot-removed.

In the normal case, post reboot, the preserved memory is filtered to
extract only relevant areas of interest using the makedumpfile tool.
While the tool provides flexibility to determine what needs to be part
of the dump and what memory to filter out, all supported distributions
default this to "Capture only kernel data and nothing else".

We take advantage of this default and the Linux kernel's Contiguous
Memory Allocator (CMA) to fundamentally change the memory reservation
model for fadump.

Instead of setting aside a significant chunk of memory nobody can use,
this patch uses CMA instead, to reserve a significant chunk of memory
that the kernel is prevented from using (due to MIGRATE_CMA), but
applications are free to use it. With this fadump will still be able
to capture all of the kernel memory and most of the user space memory
except the user pages that were present in CMA region.

Essentially, on a P9 LPAR with 2 cores, 8GB RAM and current upstream:
[root@zzxx-yy10 ~]# free -m
              total        used        free      shared  buff/cache   available
Mem:           7557         193        6822          12         541        6725
Swap:          4095           0        4095

With this patch:
[root@zzxx-yy10 ~]# free -m
              total        used        free      shared  buff/cache   available
Mem:           8133         194        7464          12         475        7338
Swap:          4095           0        4095

Changes made here are completely transparent to how fadump has
traditionally worked.

Thanks to Aneesh Kumar and Anshuman Khandual for helping us understand
CMA and its usage.

- Handle case where CMA reservation spans nodes.

294304e4c5 netfilter: conntrack: udp: set stream timeout to 2 minutes 
We have no explicit signal when a UDP stream has terminated, peers just
stop sending.

For suspected stream connections a timeout of two minutes is sane to keep
NAT mapping alive a while longer.

It matches tcp conntracks 'timewait' default timeout value.

====================
Intel Wired LAN Driver Updates 2018-12-20

This series contains updates to e100, igb, ixgbe, i40e and ice drivers.

I replaced spinlocks for mutex locks to reduce the latency on CPU0 for
igb when updating the statistics.  This work was based off a patch
provided by Jan Jablonsky, which was against an older version of the igb
driver.

Jesus adjusts the receive packet buffer size from 32K to 30K when
running in QAV mode, to stay within 60K for total packet buffer size for
igb.

Vinicius adds igb kernel documentation regarding the CBS algorithm and
its implementation in the i210 family of NICs.

YueHaibing from Huawei fixed the e100 driver that was potentially
passing a NULL pointer, so use the kernel macro IS_ERR_OR_NULL()
instead.

Konstantin Khorenko fixes i40e where we were not setting up the
neigh_priv_len in our net_device, which caused the driver to read beyond
the neighbor entry allocated memory.

Miroslav Lichvar extends the PTP gettime() to read the system clock by
adding support for PTP_SYS_OFFSET_EXTENDED ioctl in i40e.

Young Xiao fixed the ice driver to only enable NAPI on q_vectors that
actually have transmit and receive rings.

Kai-Heng Feng fixes an igb issue that when placed in suspend mode, the
NIC does not wake up when a cable is plugged in.  This was due to the
driver not setting PME during runtime suspend.

Stephen Douthit enables the ixgbe driver allow DSA devices to use the
MII interface to talk to switches.

This adds new dt entry ext-fem-name, it is used by ath10k driver
to select correct timing parameters and configure it in target wifi hardware.
The Front End Module(FEM) normally includes tx power amplifier(PA) and
rx low noise amplifier(LNA). The default timing parameters like tx end to
PA off timing values were fine tuned for internal FEM used in reference
design. And these timing values can not be same if ODM modifies hardware
design with different external FEM. This DT entry helps to choose correct
timing values in driver if different external FEM hardware used.
