edc5f445a6 VFIO updates for v4.10-rc1
- VFIO updates for v4.10 primarily include a new Mediated Device
    interface, which essentially allows software defined devices to be
    exposed to users through VFIO.  The host vendor driver providing
    this virtual device polices, or mediates user access to the device.
    These devices often incorporate portions of real devices, for
    instance the primary initial users of this interface expose vGPUs
    which allow the user to map mediated devices, or mdevs, to a
    portion of a physical GPU.  QEMU composes these mdevs into PCI
    representations using the existing VFIO user API.  This enables
    both Intel KVM-GT support, which is also expected to arrive into
    Linux mainline during the v4.10 merge window, as well as NVIDIA
    vGPU, and also Channel I/O devices (aka CCW devices) for s390
    virtualization support. (Kirti Wankhede, Neo Jia)
 
  - Drop unnecessary uses of pcibios_err_to_errno() (Cao Jin)
 
  - Fixes to VFIO capability chain handling (Eric Auger)
 
  - Error handling fixes for fallout from mdev (Christophe JAILLET)
 
  - Notifiers to expose struct kvm to mdev vendor drivers (Jike Song)
 
  - type1 IOMMU model search fixes (Kirti Wankhede, Neo Jia)

b8d2798f32 This is a fairly quiet release. We don't have any patches to the core
framework. The only patch that can even be considered "core" adds another
 clk_get() variant. The rest of the changes are in drivers for various SoCs, and
 we have a few bits for ARM shmobile architecture code (dts and mach) due to the
 dependency we're breaking between shmobile architecture code and its clk
 driver. Those shmobile bits have also been pulled into arm-soc tree. Here's the
 summary:
 
 Core:
 
  - Support for devm_get_clk_from_child() used with DT bindings that have
    subnodes with the 'clocks' property
 
 New Drivers:
 
  - Allwinner A64 (sun50i)
  - i.MX imx6ull
  - Socionext's UniPhier SoC CPUs
  - Mediatek MT2701 SoCs
  - Rockchip rk1108 SoCs
  - Qualcomm MSM8994/MSM8992 SoCS

  - Oxford Semiconductor OX820 and OX810SE SoCs
  - Renesas RZ/G1M and RZ/GIE SoCs
  - Renesas R-Car RST driver for mode pin states
 
 Updates:
 
  - Four Allwinner SoCs are migrated to the new style clk driver
  - Rockchip rk3399,rk3066 PLL optimizations
  - i.MX LVDS display glitch fixes and AV PLL precision improvements
  - Qualcomm MSM8996 GPU GDSCs, hw controlled GDSCs, and Alpha PLL support

edc57ea92c remoteproc updates for v4.10
Introduces remoteproc "subdevice" support, which allows remoteproc
 driver to associate devices to the "running" state of the remoteproc,
 allowing devices to be probed and removed as the remote processor is
 booted, shut down or recovering from a crash.
 
 Handling of virtio device resources was improved, vring memory is now
 allocated as part of other memory allocation. This ensures that all
 vrings for all virtio devices are allocated before we boot the remote
 processor.
 
 The debugfs mechanism for starting and stopping remoteproc instances was
 replaced with a sysfs interface, also providing a mechanism for
 specifying firmware to use by the instance. This allows user space to
 load and boot use case specific firmware on remote processors.
 
 New drivers for the ST Slimcore and Qualcomm Hexagon DSP as well as
 removal of the unused StE modem loader.
 
 Finally support for crash recovery in the Qualcomm Wirelss subsystem
 (used for WiFi/BT/FM on a number of platforms) and a number of bug fixes
 and cleanups.

5233c331cf It's been an busy period for mmc. Quite some changes in the mmc core, two new
mmc host drivers, some existing drivers being extended to support new IP
 versions and lots of other updates.
 
 MMC core:
  - Delete eMMC packed command support
  - Introduce mmc_abort_tuning() to enable eMMC tuning to fail gracefully
  - Introduce mmc_can_retune() to see if a host can be retuned

    a more detailed description of error conditions which allows devices
    using these regulators to build
  - ACPI support for the fixed voltage regulator.
  - Cleanups for the TI TWL drivers to reduce code duplication.

20d5ba4928 Bulk pin control changes for the v4.10 kernel cycle:
No core changes this time. Mainly gradual improvement and
 feature growth in the drivers.
 
 New drivers:
 
 - New driver for TI DA850/OMAP-L138/AM18XX pinconf
 
 - The SX150x was moved over from the GPIO subsystem and
   reimagined as a pin control driver with GPIO support
   in a joint effort by three independent users of this
   hardware. The result was amazingly good!
 
 - New subdriver for the Oxnas OX820
 
 Improvements:
 
 - The sunxi driver now supports the generic pin control
   bindings rather than the sunxi-specific. Add debouncing
   support to the driver.
 
 - Simplifications in pinctrl-single adding a generic parser.
 
 - Two downstream fixes and move the Raspberry Pi BCM2835 over
   to use the generic GPIOLIB_IRQCHIP.

061ad5038c Bulk GPIO changes for the v4.10 kernel cycle:
Core changes:
 
 - Simplify threaded interrupt handling: instead of passing
   numbed parameters to gpiochip_irqchip_add_chained() we
   create a new call: gpiochip_irqchip_add_nested() so the two
   types are clearly semantically different. Also make sure
   that all nested chips call gpiochip_set_nested_irqchip()
   which is necessary for IRQ resend to work properly if
   it happens.
 
 - Return error on seek operations for the chardev.
 
 - Clamp values set as part of gpio[d]_direction_output() so
   that anything != 0 will be send down to the driver as "1"
   not the value passed in.
 
 - ACPI can now support naming of GPIO lines, hogs and holes
   in the GPIO lists.
 
 New drivers:
 
 - The SX150x driver was deemed unfit for the GPIO subsystem
   and was moved over to a combined GPIO+pinctrl driver in the
   pinctrl subsystem.
 
 New features:
 
 - Various cleanups to various drivers.

It's another busy cycle for the docs tree, as the sphinx conversion
 continues.  Highlights include:
 
  - Further work on PDF output, which remains a bit of a pain but should be
    more solid now.
 
  - Five more DocBook template files converted to Sphinx.  Only 27 to go...
    Lots of plain-text files have also been converted and integrated.
 
  - Images in binary formats have been replaced with more source-friendly
    versions.
 
  - Various bits of organizational work, including the renaming of various
    files discussed at the kernel summit.
 
  - New documentation for the device_link mechanism.
 
 ...and, of course, lots of typo fixes and small updates.

af884cd4a5 proc: report no_new_privs state
Similar to being able to examine if a process has been correctly
confined with seccomp, the state of no_new_privs is equally interesting,
so this adds it to /proc/$pid/status.

49920d2878 mm: make transparent hugepage size public
Test programs want to know the size of a transparent hugepage.  While it
is commonly the same as the size of a hugetlbfs page (shown as
Hugepagesize in /proc/meminfo), that is not always so: powerpc
implements transparent hugepages in a different way from hugetlbfs
pages, so it's coincidence when their sizes are the same; and x86 and
others can support more than one hugetlbfs page size.

Add /sys/kernel/mm/transparent_hugepage/hpage_pmd_size to show the THP
size in bytes - it's the same for Anonymous and Shmem hugepages.  Call
it hpage_pmd_size (after HPAGE_PMD_SIZE) rather than hpage_size, in case
some transparent support for pud and pgd pages is added later.

39fa104d5b mm: remove x86-only restriction of movable_node
In commit c5320926e3 ("mem-hotplug: introduce movable_node boot
option"), the memblock allocation direction is changed to bottom-up and
then back to top-down like this:

1. memblock_set_bottom_up(true), called by cmdline_parse_movable_node().
2. memblock_set_bottom_up(false), called by x86's numa_init().

Even though (1) occurs in generic mm code, it is wrapped by #ifdef
CONFIG_MOVABLE_NODE, which depends on X86_64.

This means that when we extend CONFIG_MOVABLE_NODE to non-x86 arches,
things will be unbalanced.  (1) will happen for them, but (2) will not.

This toggle was added in the first place because x86 has a delay between
adding memblocks and marking them as hotpluggable.  Since other arches
do this marking either immediately or not at all, they do not require
the bottom-up toggle.

So, resolve things by moving (1) from cmdline_parse_movable_node() to
x86's setup_arch(), immediately after the movable_node parameter has
been parsed.

4022d039a3 net: smmac: allow configuring lower pbl values
The driver currently always sets the PBLx8/PBLx4 bit, which means that
the pbl values configured via the pbl/txpbl/rxpbl DT properties are
always multiplied by 8/4 in the hardware.

In order to allow the DT to configure lower pbl values, while at the
same time not changing behavior of any existing device trees using the
pbl/txpbl/rxpbl settings, add a property to disable the multiplication
of the pbl by 8/4 in the hardware.

89caaa2d80 net: stmmac: add support for independent DMA pbl for tx/rx
GMAC and newer supports independent programmable burst lengths for
DMA tx/rx. Add new optional devicetree properties representing this.

To be backwards compatible, snps,pbl will still be valid, but
snps,txpbl/snps,rxpbl will override the value in snps,pbl if set.

If the IP is synthesized to use the AXI interface, there is a register
and a matching DT property inside the optional stmmac-axi-config DT node
for controlling burst lengths, named snps,blen.
However, using this register, it is not possible to control tx and rx
independently. Also, this register is not available if the IP was
synthesized with, e.g., the AHB interface.

snps,tso was previously placed under AXI BUS Mode parameters,
suggesting that the property should be in the stmmac-axi-config node.

TSO (TCP Segmentation Offloading) has nothing to do with AXI BUS Mode
parameters, and the parser actually expects it to be in the root node,
not in the stmmac-axi-config.

====================
Netfilter/IPVS updates for net-next

The following patchset contains a large Netfilter update for net-next,
to summarise:

1) Add support for stateful objects. This series provides a nf_tables
   native alternative to the extended accounting infrastructure for
   nf_tables. Two initial stateful objects are supported: counters and
   quotas. Objects are identified by a user-defined name, you can fetch
   and reset them anytime. You can also use a maps to allow fast lookups
   using any arbitrary key combination. More info at:

   http://marc.info/?l=netfilter-devel&m=148029128323837&w=2

2) On-demand registration of nf_conntrack and defrag hooks per netns.
   Register nf_conntrack hooks if we have a stateful ruleset, ie.
   state-based filtering or NAT. The new nf_conntrack_default_on sysctl
   enables this from newly created netnamespaces. Default behaviour is not
   modified. Patches from Florian Westphal.

3) Allocate 4k chunks and then use these for x_tables counter allocation
   requests, this improves ruleset load time and also datapath ruleset
   evaluation, patches from Florian Westphal.

4) Add support for ebpf to the existing x_tables bpf extension.
   From Willem de Bruijn.

5) Update layer 4 checksum if any of the pseudoheader fields is updated.
   This provides a limited form of 1:1 stateless NAT that make sense in
   specific scenario, eg. load balancing.

6) Add support to flush sets in nf_tables. This series comes with a new
   set->ops->deactivate_one() indirection given that we have to walk
   over the list of set elements, then deactivate them one by one.
   The existing set->ops->deactivate() performs an element lookup that
   we don't need.

7) Two patches to avoid cloning packets, thus speed up packet forwarding
   via nft_fwd from ingress. From Florian Westphal.

8) Two IPVS patches via Simon Horman: Decrement ttl in all modes to
   prevent infinite loops, patch from Dwip Banerjee. And one minor
   refactoring from Gao feng.

9) Revisit recent log support for nf_tables netdev families: One patch
   to ensure that we correctly handle non-ethernet packets. Another
   patch to add missing logger definition for netdev. Patches from
   Liping Zhang.

10) Three patches for nft_fib, one to address insufficient register
    initialization and another to solve incorrect (although harmless)
    byteswap operation. Moreover update xt_rpfilter and nft_fib to match
    lbcast packets with zeronet as source, eg. DHCP Discover packets
    (0.0.0.0 -> 255.255.255.255). Also from Liping Zhang.

11) Built-in DCCP, SCTP and UDPlite conntrack and NAT support, from
    Davide Caratti. While DCCP is rather hopeless lately, and UDPlite has
    been broken in many-cast mode for some little time, let's give them a
    chance by placing them at the same level as other existing protocols.
    Thus, users don't explicitly have to modprobe support for this and
    NAT rules work for them. Some people point to the lack of support in
    SOHO Linux-based routers that make deployment of new protocols harder.
    I guess other middleboxes outthere on the Internet are also to blame.
    Anyway, let's see if this has any impact in the midrun.

12) Skip software SCTP software checksum calculation if the NIC comes
    with SCTP checksum offload support. From Davide Caratti.

13) Initial core factoring to prepare conversion to hook array. Three
    patches from Aaron Conole.

14) Gao Feng made a wrong conversion to switch in the xt_multiport
    extension in a patch coming in the previous batch. Fix it in this
    batch.

15) Get vmalloc call in sync with kmalloc flags to avoid a warning
    and likely OOM killer intervention from x_tables. From Marcelo
    Ricardo Leitner.

16) Update Arturo Borrero's email address in all source code headers.

Hence, calc mult and shift basing on CPTS rfclk frequency if both
cpts_clock_shift and cpts_clock_mult properties are not provided in DT (the
basis of calculation algorithm is borrowed from
__clocksource_update_freq_scale() commit 7d2f944a2b ("clocksource:
Provide a generic mult/shift factor calculation")). After this change
cpts_clock_shift and cpts_clock_mult DT properties will become optional.

The "mac_core_rst" represents "mac core reset signal", it resets
the mac core including packet processing unit, descriptor processing unit,
tx engine, rx engine, control unit.
The "mac_ifc_rst" represents "mac interface reset signal", it resets
the mac interface. The mac interface unit connects mac core and
data interface like MII/RMII/RGMII. After we set a new value of
interface mode, we must reset mac interface to reload the new mode value.
The "mac_core_rst" and "mac_ifc_rst" are both optional to be
backward compatible with the hix5hd2 SoC.
The "phy_rst" represents "phy reset signal", it does a hardware reset
on the PHY chip. This reset signal is optional if the PHY can work well
without the hardware reset.

Add one more clock signal, the existing is MAC core clock,
and the new one is MAC interface clock.
The MAC interface clock is optional to be backward compatible with
the hix5hd2 SoC.

Jon,

Did a patch fixing the quibbles.

As it seems you didn't push yet the changeset upstream, feel free to
just fold it with patch 5/5 if you prefer so, or to add as a separate
patch at the end of the series.

Patch enclosed.
