Pull char/misc driver updates from Greg KH:
"Here is the big char/misc driver update for 4.14-rc1.
Lots of different stuff in here, it's been an active development cycle
for some reason. Highlights are:
- updated binder driver, this brings binder up to date with what
shipped in the Android O release, plus some more changes that
happened since then that are in the Android development trees.
- coresight updates and fixes
- mux driver file renames to be a bit "nicer"
- intel_th driver updates
- normal set of hyper-v updates and changes
- small fpga subsystem and driver updates
- lots of const code changes all over the driver trees
- extcon driver updates
- fmc driver subsystem upadates
- w1 subsystem minor reworks and new features and drivers added
- spmi driver updates
Plus a smattering of other minor driver updates and fixes.
All of these have been in linux-next with no reported issues for a
while"

Pull driver core update from Greg KH:
"Here is the "big" driver core update for 4.14-rc1.
It's really not all that big, the largest thing here being some
firmware tests to help ensure that that crazy api is working properly.
There's also a new uevent for when a driver is bound or unbound from a
device, fixing a hole in the driver model that's been there since the
very beginning. Many thanks to Dmitry for being persistent and
pointing out how wrong I was about this all along :)
Patches for the new uevents are already in the systemd tree, if people
want to play around with them.
Otherwise just a number of other small api changes and updates here,
nothing major. All of these patches have been in linux-next for a

Pull arm64 updates from Catalin Marinas:
- VMAP_STACK support, allowing the kernel stacks to be allocated in the
vmalloc space with a guard page for trapping stack overflows. One of
the patches introduces THREAD_ALIGN and changes the generic
alloc_thread_stack_node() to use this instead of THREAD_SIZE (no
functional change for other architectures)
- Contiguous PTE hugetlb support re-enabled (after being reverted a
couple of times). We now have the semantics agreed in the generic mm
layer together with API improvements so that the architecture code
can detect between contiguous and non-contiguous huge PTEs
- Initial support for persistent memory on ARM: DC CVAP instruction
exposed to user space (HWCAP) and the in-kernel pmem API implemented
- raid6 improvements for arm64: faster algorithm for the delta syndrome
and implementation of the recovery routines using Neon
- FP/SIMD refactoring and removal of support for Neon in interrupt
context. This is in preparation for full SVE support
- PTE accessors converted from inline asm to cmpxchg so that we can use
LSE atomics if available (ARMv8.1)

With TXQs, the AP_VLAN interfaces are resolved to their owner AP
interface when enqueuing the frame, which makes sense since the
frame really goes out on that as far as the driver is concerned.
However, this introduces a problem: frames to be encrypted with
a VLAN-specific GTK will now be encrypted with the AP GTK, since
the information about which virtual interface to use to select
the key is taken from the TXQ.
Fix this by preserving info->control.vif and using that in the
dequeue function. This now requires doing the driver-mapping
in the dequeue as well.
Since there's no way to filter the frames that are sitting on a
TXQ, drop all frames, which may affect other interfaces, when an
AP_VLAN is removed.

The X-Powers AXP813 PMIC is normally used with Allwinner's A83T SoC.
It has the same range of functions as other X-Powers PMICs, such as
DC-DC buck converter and linear regulator outputs, AC-IN and VBUS
power supplies, power button trigger, GPIOs, ADCs, and a battery
charger.
Note that the IRQ table given in the datasheet is incorrect: in IRQ
enable/status registers 1, there are separate IRQs for ACIN and VBUS,
instead of bits [7:5] being the same as bits [4:2]. So it shares the
same IRQs as the AXP803, rather than the AXP288.
This patch adds basic mfd support for it, with only the power button
enabled.

Pablo Neira Ayuso says:
====================
Netfilter updates for next-net (part 2)
The following patchset contains Netfilter updates for net-next. This
patchset includes updates for nf_tables, removal of
CONFIG_NETFILTER_DEBUG and a new mode for xt_hashlimit. More
specifically, they:
1) Add new rate match mode for hashlimit, this introduces a new revision
for this match. The idea is to stop matching packets until ratelimit
criteria stands true. Patch from Vishwanath Pai.
2) Add ->select_ops indirection to nf_tables named objects, so we can
choose between different flavours of the same object type, patch from
Pablo M. Bermudo.
3) Shorter function names in nft_limit, basically:
s/nft_limit_pkt_bytes/nft_limit_bytes, also from Pablo M. Bermudo.
4) Add new stateful limit named object type, this allows us to create
limit policies that you can identify via name, also from Pablo.
5) Remove unused hooknum parameter in conntrack ->packet indirection.
From Florian Westphal.
6) Patches to remove CONFIG_NETFILTER_DEBUG and macros such as
IP_NF_ASSERT and IP_NF_ASSERT. From Varsha Rao.
7) Add nf_tables_updchain() helper function and use it from
nf_tables_newchain() to make it more maintainable. Similarly,
add nf_tables_addchain() and use it too.
8) Add new netlink NLM_F_NONREC flag, this flag should only be used for
deletion requests, specifically, to support non-recursive deletion.
Based on what we discussed during NFWS'17 in Faro.
9) Use NLM_F_NONREC from table and sets in nf_tables.
10) Support for recursive chain deletion. Table and set deletion
commands come with an implicit content flush on deletion, while
chains do not. This patch addresses this inconsistency by adding
the code to perform recursive chain deletions. This also comes with
the bits to deal with the new NLM_F_NONREC netlink flag.

Pull x86 cache quality monitoring update from Thomas Gleixner:
"This update provides a complete rewrite of the Cache Quality
Monitoring (CQM) facility.
The existing CQM support was duct taped into perf with a lot of issues
and the attempts to fix those turned out to be incomplete and
horrible.
After lengthy discussions it was decided to integrate the CQM support
into the Resource Director Technology (RDT) facility, which is the
obvious choise as in hardware CQM is part of RDT. This allowed to add
Memory Bandwidth Monitoring support on top.
As a result the mechanisms for allocating cache/memory bandwidth and
the corresponding monitoring mechanisms are integrated into a single
management facility with a consistent user interface"

Pull x86 mm changes from Ingo Molnar:
"PCID support, 5-level paging support, Secure Memory Encryption support
The main changes in this cycle are support for three new, complex
hardware features of x86 CPUs:
- Add 5-level paging support, which is a new hardware feature on
upcoming Intel CPUs allowing up to 128 PB of virtual address space
and 4 PB of physical RAM space - a 512-fold increase over the old
limits. (Supercomputers of the future forecasting hurricanes on an
ever warming planet can certainly make good use of more RAM.)
Many of the necessary changes went upstream in previous cycles,
v4.14 is the first kernel that can enable 5-level paging.
This feature is activated via CONFIG_X86_5LEVEL=y - disabled by
default.
(By Kirill A. Shutemov)
- Add 'encrypted memory' support, which is a new hardware feature on
upcoming AMD CPUs ('Secure Memory Encryption', SME) allowing system
RAM to be encrypted and decrypted (mostly) transparently by the
CPU, with a little help from the kernel to transition to/from
encrypted RAM. Such RAM should be more secure against various
attacks like RAM access via the memory bus and should make the
radio signature of memory bus traffic harder to intercept (and
decrypt) as well.
This feature is activated via CONFIG_AMD_MEM_ENCRYPT=y - disabled
by default.
(By Tom Lendacky)
- Enable PCID optimized TLB flushing on newer Intel CPUs: PCID is a
hardware feature that attaches an address space tag to TLB entries
and thus allows to skip TLB flushing in many cases, even if we
switch mm's.
(By Andy Lutomirski)
All three of these features were in the works for a long time, and
it's coincidence of the three independent development paths that they
are all enabled in v4.14 at once"

Compared to the old xrx200_phy_fw driver the new version has multiple
enhancements. The name of the firmware files does not have to be added
to all .dts files anymore - one now configures the GPHY mode (FE or GE)
instead. Each GPHY can now also boot separate firmware (thus mixing of
GE and FE GPHYs is now possible).
The new implementation is based on the RCU syscon-mfd and uses the
reeset_controller framework instead of raw RCU register reads/writes.
