We are planning to share more code between different NAND based
devices (SPI NAND, OneNAND and raw NANDs), but before doing that
we need to move the existing include/linux/mtd/nand.h file into
include/linux/mtd/rawnand.h so we can later create a nand.h header
containing all common structure and function prototypes.

This fix was intended for 4.13, but didn't get in because both
maintainers were on vacation.
Paul Mackerras:
"It adds mutual exclusion between list_add_rcu and list_del_rcu calls
on the kvm->arch.spapr_tce_tables list. Without this, userspace could
potentially trigger corruption of the list and cause a host crash or
worse."

The ARM-ARM has two bits in the ESR/HSR relevant to external aborts.
A range of {I,D}FSC values (of which bit 5 is always set) and bit 9 'EA'
which provides:
> an IMPLEMENTATION DEFINED classification of External Aborts.
This bit is in addition to the {I,D}FSC range, and has an implementation
defined meaning. KVM should always ignore this bit when handling external
aborts from a guest.
Remove the ESR_ELx_EA definition and rewrite its helper
kvm_vcpu_dabt_isextabt() to check the {I,D}FSC range. This merges
kvm_vcpu_dabt_isextabt() and the recently added is_abort_sea() helper.

If a vcpu exits due to request a user mode spinlock, then
the spinlock-holder may be preempted in user mode or kernel mode.
(Note that not all architectures trap spin loops in user mode,
only AMD x86 and ARM/ARM64 currently do).
But if a vcpu exits in kernel mode, then the holder must be
preempted in kernel mode, so we should choose a vcpu in kernel mode
as a more likely candidate for the lock holder.
This introduces kvm_arch_vcpu_in_kernel() to decide whether the
vcpu is in kernel-mode when it's preempted. kvm_vcpu_on_spin's
new argument says the same of the spinning VCPU.

It's not correct to encode the subsystem in the I2C device name, so
drop the -mfd suffix. To maintain bisect-ability, change driver and
platform code / DTS users in the same patch.

Pull media updates from Mauro Carvalho Chehab:
"Brazil's Independence Day pull request :-)
This is one of the biggest media pull requests, with 625 patches
affecting almost all parts of media (RC, DVB, V4L2, CEC, docs).
This contains:
- A lot of new drivers:
* DVB frontends: mxl5xx, stv0910, stv6111;
* camera flash: as3645a led driver;
* HDMI receiver: adv748X;
* camera sensor: Omnivision 6650 5M driver (ov6650);
* HDMI CEC: ao-cec meson driver;
* V4L2: Qualcom camss driver;
* Remote controller: gpio-ir-tx, pwm-ir-tx and zx-irdec drivers.
- The DDbridge DVB driver got a massive update, with makes it in sync
with modern hardware from that vendor;
- There's an important milestone on this series: the DVB
documentation was written in 2003, but only started to be updated
in 2007. It also used to contain several gaps from the time it was
kept out of tree, mentioning error codes and device nodes that
never existed upstream. On this series, it received a massive
update: all non-deprecated digital TV APIs are now in sync with the
current implementation;
- Some DVB APIs that aren't used by any upstream driver got removed;
- Other parts of the media documentation algo got updated, fixing
some bugs on its PDF output and making it compatible with Sphinx
version 1.6.
As the number of hacks required to build PDF output reduced, I hope
we'll have less troubles as newer versions of our documentation
toolchain are released (famous last words);
- As usual, lots of driver cleanups and improvements"

Pull EFI updates from Ingo Molnar:
"The main changes in this cycle were:
- Transparently fall back to other poweroff method(s) if EFI poweroff
fails (and returns)
- Use separate PE/COFF section headers for the RX and RW parts of the
ARM stub loader so that the firmware can use strict mapping
permissions
- Add support for requesting the firmware to wipe RAM at warm reboot
- Increase the size of the random seed obtained from UEFI so CRNG
fast init can complete earlier
- Update the EFI framebuffer address if it points to a BAR that gets
moved by the PCI resource allocation code
- Enable "reset attack mitigation" of TPM environments: this is
enabled if the kernel is configured with
CONFIG_RESET_ATTACK_MITIGATION=y.
- Clang related fixes
- Misc cleanups, constification, refactoring, etc"

To prevent unintended modifications to the kernel text (malicious or
otherwise) while running the EFI stub, describe the kernel image as
two separate sections: a .text section with read-execute permissions,
covering .text, .rodata, .piggytext and the GOT sections (which the
stub does not care about anyway), and a .data section with read-write
permissions, covering .data and .bss.
This relies on the firmware to actually take the section permission
flags into account, but this is something that is currently being
implemented in EDK2, which means we will likely start seeing it in
the wild between one and two years from now.

The kernel's EFI PE/COFF header contains a dummy .reloc section, and
an explanatory comment that claims that this is required for the EFI
application loader to accept the Image as a relocatable image (i.e.,
one that can be loaded at any offset and fixed up in place)
This was inherited from the x86 implementation, which has elaborate host
tooling to mangle the PE/COFF header post-link time, and which populates
the .reloc section with a single dummy base relocation. On ARM, no such
tooling exists, and the .reloc section remains empty, and is never even
exposed via the BaseRelocationTable directory entry, which is where the
PE/COFF loader looks for it.
The PE/COFF spec is unclear about relocatable images that do not require
any fixups, but the EDK2 implementation, which is the de facto reference
for PE/COFF in the UEFI space, clearly does not care, and explicitly
mentions (in a comment) that relocatable images with no base relocations
are perfectly fine, as long as they don't have the RELOCS_STRIPPED
attribute set (which is not the case for our PE/COFF image)
So simply remove the .reloc section altogether.

For the final round, avoid the expanded and padded lookup tables
exported by the generic AES driver. Instead, for encryption, we can
perform byte loads from the same table we used for the inner rounds,
which will still be hot in the caches. For decryption, use the inverse
AES Sbox directly, which is 4x smaller than the inverse lookup table
exported by the generic driver.
This should significantly reduce the Dcache footprint of our code,
which makes the code more robust against timing attacks. It does not
introduce any additional module dependencies, given that we already
rely on the core AES module for the shared key expansion routines.

Implement a NEON fallback for systems that do support NEON but have
no support for the optional 64x64->128 polynomial multiplication
instruction that is part of the ARMv8 Crypto Extensions. It is based
on the paper "Fast Software Polynomial Multiplication on ARM Processors
Using the NEON Engine" by Danilo Camara, Conrado Gouvea, Julio Lopez and
Ricardo Dahab (https://hal.inria.fr/hal-01506572)
On a 32-bit guest executing under KVM on a Cortex-A57, the new code is
not only 4x faster than the generic table based GHASH driver, it is also
time invariant. (Note that the existing vmull.p64 code is 16x faster on
this core).

There are quite a number of occurrences in the kernel of the pattern
if (dst != src)
memcpy(dst, src, walk.total % AES_BLOCK_SIZE);
crypto_xor(dst, final, walk.total % AES_BLOCK_SIZE);
or
crypto_xor(keystream, src, nbytes);
memcpy(dst, keystream, nbytes);
where crypto_xor() is preceded or followed by a memcpy() invocation
that is only there because crypto_xor() uses its output parameter as
one of the inputs. To avoid having to add new instances of this pattern
in the arm64 code, which will be refactored to implement non-SIMD
fallbacks, add an alternative implementation called crypto_xor_cpy(),
taking separate input and output arguments. This removes the need for
the separate memcpy().

The JIT compiler emits ARM 32 bit instructions. Currently, It supports
eBPF only. Classic BPF is supported because of the conversion by BPF core.
This patch is essentially changing the current implementation of JIT compiler
of Berkeley Packet Filter from classic to internal with almost all
instructions from eBPF ISA supported except the following
BPF_ALU64 | BPF_DIV | BPF_K
BPF_ALU64 | BPF_DIV | BPF_X
BPF_ALU64 | BPF_MOD | BPF_K
BPF_ALU64 | BPF_MOD | BPF_X
BPF_STX | BPF_XADD | BPF_W
BPF_STX | BPF_XADD | BPF_DW
Implementation is using scratch space to emulate 64 bit eBPF ISA on 32 bit
ARM because of deficiency of general purpose registers on ARM. Currently,
only LITTLE ENDIAN machines are supported in this eBPF JIT Compiler.
Tested on ARMv7 with QEMU by me (Shubham Bansal).
Testing results on ARMv7:
1) test_bpf: Summary: 341 PASSED, 0 FAILED, [312/333 JIT'ed]
2) test_tag: OK (40945 tests)
3) test_progs: Summary: 30 PASSED, 0 FAILED
4) test_lpm: OK
5) test_lru_map: OK
Above tests are all done with following flags enabled discreatly.
1) bpf_jit_enable=1

Pull power management updates from Rafael Wysocki:
"This time (again) cpufreq gets the majority of changes which mostly
are driver updates (including a major consolidation of intel_pstate),
some schedutil governor modifications and core cleanups.
There also are some changes in the system suspend area, mostly related
to diagnostics and debug messages plus some renames of things related
to suspend-to-idle. One major change here is that suspend-to-idle is
now going to be preferred over S3 on systems where the ACPI tables
indicate to do so and provide requsite support (the Low Power Idle S0
_DSM in particular). The system sleep documentation and the tools
related to it are updated too.
The rest is a few cpuidle changes (nothing major), devfreq updates,
generic power domains (genpd) framework updates and a few assorted
modifications elsewhere.
Specifics:
- Drop the P-state selection algorithm based on a PID controller from
intel_pstate and make it use the same P-state selection method
(based on the CPU load) for all types of systems in the active mode
(Rafael Wysocki, Srinivas Pandruvada).
- Rework the cpufreq core and governors to make it possible to take
cross-CPU utilization updates into account and modify the schedutil
governor to actually do so (Viresh Kumar).
- Clean up the handling of transition latency information in the
cpufreq core and untangle it from the information on which drivers
cannot do dynamic frequency switching (Viresh Kumar).
- Add support for new SoCs (MT2701/MT7623 and MT7622) to the mediatek
cpufreq driver and update its DT bindings (Sean Wang).
- Modify the cpufreq dt-platdev driver to autimatically create
cpufreq devices for the new (v2) Operating Performance Points (OPP)
DT bindings and update its whitelist of supported systems (Viresh
Kumar, Shubhrajyoti Datta, Marc Gonzalez, Khiem Nguyen, Finley
Xiao).
- Add support for Ux500 to the cpufreq-dt driver and drop the
obsolete dbx500 cpufreq driver (Linus Walleij, Arnd Bergmann).
- Add new SoC (R8A7795) support to the cpufreq rcar driver (Khiem
Nguyen).
- Fix and clean up assorted issues in the cpufreq drivers and core
(Arvind Yadav, Christophe Jaillet, Colin Ian King, Gustavo Silva,
Julia Lawall, Leonard Crestez, Rob Herring, Sudeep Holla).
- Update the IO-wait boost handling in the schedutil governor to make
it less aggressive (Joel Fernandes).
- Rework system suspend diagnostics to make it print fewer messages
to the kernel log by default, add a sysfs knob to allow more
suspend-related messages to be printed and add Low Power S0 Idle
constraints checks to the ACPI suspend-to-idle code (Rafael
Wysocki, Srinivas Pandruvada).
- Prefer suspend-to-idle over S3 on ACPI-based systems with the
ACPI_FADT_LOW_POWER_S0 flag set and the Low Power Idle S0 _DSM
interface present in the ACPI tables (Rafael Wysocki).
- Update documentation related to system sleep and rename a number of
items in the code to make it cleare that they are related to
suspend-to-idle (Rafael Wysocki).
- Export a variable allowing device drivers to check the target
system sleep state from the core system suspend code (Florian
Fainelli).
- Clean up the cpuidle subsystem to handle the polling state on x86
in a more straightforward way and to use %pOF instead of full_name
(Rafael Wysocki, Rob Herring).
- Update the devfreq framework to fix and clean up a few minor issues
(Chanwoo Choi, Rob Herring).
- Extend diagnostics in the generic power domains (genpd) framework
and clean it up slightly (Thara Gopinath, Rob Herring).
- Fix and clean up a couple of issues in the operating performance
points (OPP) framework (Viresh Kumar, Waldemar Rymarkiewicz).
- Add support for RV1108 to the rockchip-io Adaptive Voltage Scaling
(AVS) driver (David Wu).
- Fix the usage of notifiers in CPU power management on some
platforms (Alex Shi).
- Update the pm-graph system suspend/hibernation and boot profiling
utility (Todd Brandt).
- Make it possible to run the cpupower utility without CPU0 (Prarit
Bhargava)"

The new 'select CPUFREQ_DT' statement causes a warning in some
configurations:
warning: (ARCH_U8500) selects CPUFREQ_DT which has unmet direct dependencies (CPU_FREQ && HAVE_CLK && OF && (!CPU_THERMAL || THERMAL))
No other platform does this, so I think for consistency it's
best if we remove it again from ux500 and instead add the driver
to the defconfig.

We have moved the Ux500 over to use the generic DT based
cpufreq driver, so delete the old custom driver.
At the same time select CPUFREQ_DT from the machine's
Kconfig in order to satisfy the "default ARCH_U8500"
selection on the old driver.

On tango platforms, firmware configures the CPU clock, and Linux is
then only allowed to use the cpu_clk_divider to change the frequency.
Build the OPP table dynamically at init, in order to support whatever
firmware throws at us.

Pull pin control updates from Linus Walleij:
"This is the big bulk of pin control changes for the v4.14 kernel.
There are just a few bigger changes (new drivers mostly) and then a
lot of small patches all over the place.
Core changes:
- Decision to wrap the sleep mode of the Spreadtrum and in the future
others into a specially tagged state. The generic DT bindings and
the new Spreadtrum driver conforms to this. Others should be moved
over if possible.
New drivers:
- Spreadtrum SoCs especially the SC9860 SoC.
- Storlink/Cortina Gemini 3512 and 3516 SoCs.
New subdrivers:
- Intel Denverton subdriver.
- Intel Cannon Lake subdriver.
- Intel Lewisburg subdriver.
- Allwinner sunxi: R40 subdriver for A10.
- Socionext uniphier PXs3 subdriver.
- Rockchip RK3128 subdriver.
- Renesas SH-PFC R8A77995 subdriver.
Miscellaneous:
- Qualcomm APQ8064 can handle general purpose clock muxing.
- Mediatek MT7623 PCIe mux data fixed up.
- Intel GPIO IRQs are disabled during suspend.
- Several fixes and addtions to Renesas r8a7796.
- Qualcomm SPMI GPIO supports dtest route and LV/MV subtype.
- Input schmitt trigger support in Rockchip RV1108.
- Aspeed G4 and G5 USB host/device pin control control added.
- Qualcomm IPQ4019 has matured with a few missing pin groups and
control bits put in place.
- Lots of constification, this is the latest in cocinelle fixes"

"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.
