====================
Netfilter fixes for net

This is a large batch of Netfilter fixes for net, they are:

1) Three patches to fix NAT conversion to rhashtable: Switch to rhlist
   structure that allows to have several objects with the same key.
   Moreover, fix wrong comparison logic in nf_nat_bysource_cmp() as this is
   expecting a return value similar to memcmp(). Change location of
   the nat_bysource field in the nf_conn structure to avoid zeroing
   this as it breaks interaction with SLAB_DESTROY_BY_RCU and lead us
   to crashes. From Florian Westphal.

2) Don't allow malformed fragments go through in IPv6, drop them,
   otherwise we hit GPF, patch from Florian Westphal.

3) Fix crash if attributes are missing in nft_range, from Liping Zhang.

4) Fix arptables 32-bits userspace 64-bits kernel compat, from Hongxu Jia.

5) Two patches from David Ahern to fix netfilter interaction with vrf.
   From David Ahern.

6) Fix element timeout calculation in nf_tables, we take milliseconds
   from userspace, but we use jiffies from kernelspace. Patch from
   Anders K.  Pedersen.

7) Missing validation length netlink attribute for nft_hash, from
   Laura Garcia.

8) Fix nf_conntrack_helper documentation, we don't default to off
   anymore for a bit of time so let's get this in sync with the code.

I know is late but I think these are important, specifically the NAT
bits, as they are mostly addressing fallout from recent changes. I also
read there are chances to have -rc8, if that is the case, that would
also give us a bit more time to test this.

e5f3a4a56c Documentation: devicetree: clarify usage of the RGMII phy-modes
RGMII requires special RX and/or TX delays depending on the actual
hardware circuit/wiring. These delays can be added by the MAC, the PHY
or the designer of the circuit (the latter means that no delay has to
be added by PHY or MAC).
There are 4 RGMII phy-modes used describe where a delay should be
applied:
- rgmii: the RX and TX delays are either added by the MAC (where the
  exact delay is typically configurable, and can be turned off when no
  extra delay is needed) or not needed at all (because the hardware
  wiring adds the delay already). The PHY should neither add the RX nor
  TX delay in this case.
- rgmii-rxid: configures the PHY to enable the RX delay. The MAC should
  not add the RX delay in this case.
- rgmii-txid: configures the PHY to enable the TX delay. The MAC should
  not add the TX delay in this case.
- rgmii-id: combines rgmii-rxid and rgmii-txid and thus configures the
  PHY to enable the RX and TX delays. The MAC should neither add the RX
  nor TX delay in this case.

Document these cases in the ethernet.txt documentation to make it clear
when to use each mode.
If applied incorrectly one might end up with MAC and PHY both enabling
for example the TX delay, which breaks ethernet TX traffic on 1000Mbit/s
links.

77079b133f ARM: SoC fixes for v4.9-rc
Again a set of smaller fixes across several platforms (OMAP, Marvell,
 Allwinner, i.MX, etc).
 
 A handful of typo fixes and smaller missing contents from device trees,
 with some tweaks to OMAP mach files to deal with CPU feature print
 misformatting, potential NULL ptr dereference and one setup issue
 with UARTs.

e3fd9a93a1 kvm: kvmclock: let KVM_GET_CLOCK return whether the master clock is in use
Userspace can read the exact value of kvmclock by reading the TSC
and fetching the timekeeping parameters out of guest memory.  This
however is brittle and not necessary anymore with KVM 4.11.  Provide
a mechanism that lets userspace know if the new KVM_GET_CLOCK
semantics are in effect, and---since we are at it---if the clock
is stable across all VCPUs.

52cad4b54d Fixes for omaps for v4.9-rc cycle. Except for the omap3 fix for the SoC
features printed, all these are quite trivial and tiny. The omap5 jack
 detection and gpadc patches are not strictly fixes, but I wanted to get
 binding document typo fixed before it pops up on other boards. The
 gpadc one liner was in the same series and I applied and pushed it out
 already before noticing it could have waited. The list of changes is:
 
 - Fix omap3 SoC features printed
 
 - Make sure OMAP_INTERCONNECT is selected for am43xx only configurations
 
 - Add missing memory node for torpedo
 
 - Initialize uart4_mask properly to avoid writing garbage to PRM registers
 
 - Fix NULL pointer dereference for omap4 volt_data
 
 - Add alias for omap5 gpadc needed by iio drivers
 
 - Enable omap5 jack headset jack detection and fix it's binding typo

1c8018f7a7 ipmi/bt-bmc: change compatible node to 'aspeed, ast2400-ibt-bmc'
The Aspeed SoCs have two BT interfaces : one is IPMI compliant and the
other is H8S/2168 compliant.

The current ipmi/bt-bmc driver implements the IPMI version and we
should reflect its nature in the compatible node name using
'aspeed,ast2400-ibt-bmc' instead of 'aspeed,ast2400-bt-bmc'. The
latter should be used for a H8S interface driver if it is implemented
one day.

31a3a7b5b2 PCI: rockchip: Add three new resets as required properties
pm_rst, aclk_rst, pclk_rst was controlled by ROM code so the software
wasn't needed to control it again in theory.  But it didn't work properly,
so we do need to do it again and add enough delay between the assert of
pm_rst and the deassert of pm_rst.  The Soc intergrated with this
controller, rk3399, is still under MP test internally, so the backward
compatibility won't be a big deal.

I made a mistake as for naming for this block.  The MIO block is not
implemented for these 3 SoCs in the first place.  The current naming
will be a trouble if an SoC with both MIO and SD-ctrl blocks appear
in the future.

This driver has just been merged in the previous merge window.
Rename it before the release.

  65376df582 ("proc: revert /proc/<pid>/maps [stack:TID] annotation")

Originally, /proc/PID/task/TID/maps was the same as /proc/TID/maps.

In current kernels, /proc/PID/maps (or /proc/TID/maps even for
threads) shows "[stack]" for VMAs in the mm's stack address range.

In contrast, /proc/PID/task/TID/maps uses KSTK_ESP to guess the
target thread's stack's VMA.  This is racy, probably returns garbage
and, on arches with CONFIG_TASK_INFO_IN_THREAD=y, is also crash-prone:
KSTK_ESP is not safe to use on tasks that aren't known to be running
ordinary process-context kernel code.

This patch removes the difference and just shows "[stack]" for VMAs
in the mm's stack range.  This is IMO much more sensible -- the
actual "stack" address really is treated specially by the VM code,
and the current thread stack isn't even well-defined for programs
that frequently switch stacks on their own.

5c6201e60a clk: uniphier: rename MIO clock to SD clock for Pro5, PXs2, LD20 SoCs
I made a mistake as for naming for this block.  The MIO block is not
implemented for these 3 SoCs in the first place.  The current naming
will be a trouble if an SoC with both MIO and SD-ctrl blocks appear
in the future.

This driver has just been merged in the previous merge window.
Rename it before the release.

70b565bbdb cxl: Prevent adapter reset if an active context exists
This patch prevents resetting the cxl adapter via sysfs in presence of
one or more active cxl_context on it. This protects against an
unrecoverable error caused by PSL owning a dirty cache line even after
reset and host tries to touch the same cache line. In case a force reset
of the card is required irrespective of any active contexts, the int
value -1 can be stored in the 'reset' sysfs attribute of the card.

The patch introduces a new atomic_t member named contexts_num inside
struct cxl that holds the number of active context attached to the card
, which is checked against '0' before proceeding with the reset. To
prevent against a race condition where a context is activated just after
reset check is performed, the contexts_num is atomically set to '-1'
after reset-check to indicate that no more contexts can be activated on
the card anymore.

Before activating a context we atomically test if contexts_num is
non-negative and if so, increment its value by one. In case the value of
contexts_num is negative then it indicates that the card is about to be
reset and context activation is error-ed out at that point.

8eb37aff76 pinctrl: aspeed-g5: Fix pin association of SPI1 function
The SPI1 function was associated with the wrong pins: The functions that
those pins provide is either an SPI debug or passthrough function
coupled to SPI1. Make the SPI1 mux function configure the relevant pins
and associate new SPI1DEBUG and SPI1PASSTHRU functions with the pins
that were already defined.

The notation used in the datasheet's multi-function pin table for the SoC is
often creative: in this case the SYS* signals are enabled by a single bit,
which is nothing unusual on its own, but in this case the bit was also
participating in a multi-bit bitfield and therefore represented multiple
functions. This fact was overlooked in the original patch.

commit is now reverted, so also revert this commit.

The binding is valid and shouldn't be deprecated.

dm-raid 1.9.0 fails to activate existing RAID4/10 devices that have the
old superblock format (which does not have takeover/reshaping support
that was added via commit 33e53f0685).

Fix validation path for old superblocks by reverting to the old raid4
layout and basing checks on mddev->new_{level,layout,...} members in
super_init_validation().
