167569343f ARM: SoC platform updates for 4.17
This release brings up a new platform based on the old ARM9 core: the
 Nuvoton NPCM is used as a baseboard management controller, competing
 with the better known ASpeed AST2xx series.
 
 Another important change is the addition of ARMv7-A based chips
 in mach-stm32. The older parts in this platform are ARMv7-M based
 microcontrollers, now they are expanding to general-purpose workloads.
 
 The other changes are the usual defconfig updates to enable additional
 drivers, lesser bugfixes. The largest updates as often are the ongoing
 OMAP cleanups, but we also have a number of changes for the older
 PXA and davinci platforms this time.
 
 For the Renesas shmobile/r-car platform, some new infrastructure
 is needed to make the watchdog work correctly.
 
 Supporting Multiprocessing on Allwinner A80 required a significant
 amount of new code, but is not doing anything unexpected.

b240b419db ARM: SoC device tree updates for 4.17
This is the usual set of changes for device trees, with over 700
 non-merged changesets. There is an ongoing set of dtc warning fixes and
 the usual bugfixes, cleanups and added device support.
 
 The most interesting bit as usual is support for new machines listed
 below:
 
 - The Allwinner H6 makes its debut with the Pine-H64 board, and we get
   two new machines based on its older siblings: the H5 based OrangePi
   Zero+ and the A64 based Teres-I Laptop from Olimex. On the 32-bit side,
   we add The Olimex som204 based on Allwinner A20, and the Banana Pi M2
   Zero development board (based on H2).
 
 - NVIDIA adds support for Tegra194 aka "Xavier", plus their p2972
   development board and p2888 CPU module.
 
 - The Nuvoton npcm750 is a BMC that was newly added, for now we only
   support running on the evaluation board.
 
 - STmicroelectronics stm32 gains support for the stm32mp157c and two
   evaluation boards.
 
 - The Toradex Colibri board family grows a few members based on the
   i.MX6ULL variant.
 
 - The Advantec DMS-BA16 is a Qseven module using the NXP i.MX6
   family of chips.
 
 - The Phytec phyBOARD Mira is a family of industrial boards based on
   i.MX6. For now, four models get added.
 
 - TI am335x based PDU-001 is an industrial embedded machine used for
   traffic monitoring
 
 - The Aspeed platform now supports running on the BMC on the Qualcomm
   Centriq 2400 server
 
 - Samsung Exynos4 based Galaxy S3 is a family of mobile phones Qualcomm
   msm8974 based Galaxy S5 is a rather different phone made by the same
   company.
 
 - The Xilinx Zynq and ZynqMP platforms now gained a lot of dts file
   for the various boards made by Xilinx themselves, as well as the
   Digilent Zybo Z7.
 
 - The ARM Versatile family now supports the "IB2" interface board.
 
 - The Renesas H2 based "Stout" and the H3 based Salvator-X are more
   evaluation boards named after a kind of beer, as most of them are.
   The r8a77980 (V3H) based "Condor" apparently doesn't follow that
   tradition. ;-)
 
 - ROC-RK3328-CC is a simple developement board from the Libre Computer
   Project, based on the Rockchips RK3328 SoC
 
 - Haiku is another development board plus Qseven module based on Rockchips
   RK3368 and made by Theobroma Systems.

23221d997b arm64 updates for 4.17
Nothing particularly stands out here, probably because people were tied
 up with spectre/meltdown stuff last time around. Still, the main pieces
 are:
 
 - Rework of our CPU features framework so that we can whitelist CPUs that
   don't require kpti even in a heterogeneous system
 
 - Support for the IDC/DIC architecture extensions, which allow us to elide
   instruction and data cache maintenance when writing out instructions
 
 - Removal of the large memory model which resulted in suboptimal codegen
   by the compiler and increased the use of literal pools, which could
   potentially be used as ROP gadgets since they are mapped as executable
 
 - Rework of forced signal delivery so that the siginfo_t is well-formed
   and handling of show_unhandled_signals is consolidated and made
   consistent between different fault types
 
 - More siginfo cleanup based on the initial patches from Eric Biederman
 
 - Workaround for Cortex-A55 erratum #1024718
 
 - Some small ACPI IORT updates and cleanups from Lorenzo Pieralisi
 
 - Misc cleanups and non-critical fixes

Pull arm64 updates from Will Deacon:
 "Nothing particularly stands out here, probably because people were
  tied up with spectre/meltdown stuff last time around. Still, the main
  pieces are:

   - Rework of our CPU features framework so that we can whitelist CPUs
     that don't require kpti even in a heterogeneous system

   - Support for the IDC/DIC architecture extensions, which allow us to
     elide instruction and data cache maintenance when writing out
     instructions

   - Removal of the large memory model which resulted in suboptimal
     codegen by the compiler and increased the use of literal pools,
     which could potentially be used as ROP gadgets since they are
     mapped as executable

   - Rework of forced signal delivery so that the siginfo_t is
     well-formed and handling of show_unhandled_signals is consolidated
     and made consistent between different fault types

   - More siginfo cleanup based on the initial patches from Eric
     Biederman

   - Workaround for Cortex-A55 erratum #1024718

   - Some small ACPI IORT updates and cleanups from Lorenzo Pieralisi

   - Misc cleanups and non-critical fixes"

667b24d049 arm64: Set CONFIG_MULTI_IRQ_HANDLER
arm has an optional MULTI_IRQ_HANDLER, which arm64 copied but didn't make
optional.  The multi irq handler infrastructure has been copied to generic
code selectable with a new config symbol. That symbol can be selected by
randconfig builds and can cause build breakage.

Introduce CONFIG_MULTI_IRQ_HANDLER as an intermediate step which prevents
the core config symbol from being selected. The arm64 local config symbol
will be removed once arm64 gets converted to the generic code.

642e7fd233 Merge branch 'syscalls-next' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux
Pull removal of in-kernel calls to syscalls from Dominik Brodowski:
 "System calls are interaction points between userspace and the kernel.
  Therefore, system call functions such as sys_xyzzy() or
  compat_sys_xyzzy() should only be called from userspace via the
  syscall table, but not from elsewhere in the kernel.

  At least on 64-bit x86, it will likely be a hard requirement from
  v4.17 onwards to not call system call functions in the kernel: It is
  better to use use a different calling convention for system calls
  there, where struct pt_regs is decoded on-the-fly in a syscall wrapper
  which then hands processing over to the actual syscall function. This
  means that only those parameters which are actually needed for a
  specific syscall are passed on during syscall entry, instead of
  filling in six CPU registers with random user space content all the
  time (which may cause serious trouble down the call chain). Those
  x86-specific patches will be pushed through the x86 tree in the near
  future.

  Moreover, rules on how data may be accessed may differ between kernel
  data and user data. This is another reason why calling sys_xyzzy() is
  generally a bad idea, and -- at most -- acceptable in arch-specific
  code.

  This patchset removes all in-kernel calls to syscall functions in the
  kernel with the exception of arch/. On top of this, it cleans up the
  three places where many syscalls are referenced or prototyped, namely
  kernel/sys_ni.c, include/linux/syscalls.h and include/linux/compat.h"

a90f590a1b mm: add ksys_mmap_pgoff() helper; remove in-kernel calls to sys_mmap_pgoff()
Using this helper allows us to avoid the in-kernel calls to the
sys_mmap_pgoff() syscall. The ksys_ prefix denotes that this function is
meant as a drop-in replacement for the syscall. In particular, it uses the
same calling convention as sys_mmap_pgoff().

This patch is part of a series which removes in-kernel calls to syscalls.
On this basis, the syscall entry path can be streamlined. For details, see

fd553821a9 The rk3399 gained support its Cadence displayport controller and some
minor additions like pins for 2ch i2s0 and the cif test clocks as well
 as a default rate for ACLK_VIO that should be 400MHz according to the TRM.
 
 The rk3328 got uart dmas fixed - a non-critical fix, as nobody was using
 that so far.
 
 New boards are the rk3328-based roc-rk3328-cc, the rk3368-based Lion-SOM
 + baseborad from Theobroma Systems and a standalone variant of the Sapphire
 board, as a lot of people where using that without the Exkavator baseboard.
 
 Sapphire also saw a lot of small cleanups of things that are not part
 of the actual Sapphire board, but the baseboard instead. The rk3399-puma
 board got i2s and tsadc support and Gru got its DP node enabled.

Merge tag 'v4.17-rockchip-dts64-1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into next/dt

Pull "Rockchip dts64 changes for 4.17" from Heiko Stübner:

The rk3399 gained support its Cadence displayport controller and some
minor additions like pins for 2ch i2s0 and the cif test clocks as well
as a default rate for ACLK_VIO that should be 400MHz according to the TRM.

The rk3328 got uart dmas fixed - a non-critical fix, as nobody was using
that so far.

New boards are the rk3328-based roc-rk3328-cc, the rk3368-based Lion-SOM
+ baseborad from Theobroma Systems and a standalone variant of the Sapphire
board, as a lot of people where using that without the Exkavator baseboard.

Sapphire also saw a lot of small cleanups of things that are not part
of the actual Sapphire board, but the baseboard instead. The rk3399-puma
board got i2s and tsadc support and Gru got its DP node enabled.

65896545b6 arm64: uaccess: Fix omissions from usercopy whitelist
When the hardend usercopy support was added for arm64, it was
concluded that all cases of usercopy into and out of thread_struct
were statically sized and so didn't require explicit whitelisting
of the appropriate fields in thread_struct.

Testing with usercopy hardening enabled has revealed that this is
not the case for certain ptrace regset manipulation calls on arm64.
This occurs because the sizes of usercopies associated with the
regset API are dynamic by construction, and because arm64 does not
always stage such copies via the stack: indeed the regset API is
designed to avoid the need for that by adding some bounds checking.

This is currently believed to affect only the fpsimd and TLS
registers.

Because the whitelisted fields in thread_struct must be contiguous,
this patch groups them together in a nested struct.  It is also
necessary to be able to determine the location and size of that
struct, so rather than making the struct anonymous (which would
save on edits elsewhere) or adding an anonymous union containing
named and unnamed instances of the same struct (gross), this patch
gives the struct a name and makes the necessary edits to code that
references it (noisy but simple).

Care is needed to ensure that the new struct does not contain
padding (which the usercopy hardening would fail to protect).

For this reason, the presence of tp2_value is made unconditional,
since a padding field would be needed there in any case.  This pads
up to the 16-byte alignment required by struct user_fpsimd_state.

20b8547277 arm64: fpsimd: Split cpu field out from struct fpsimd_state
In preparation for using a common representation of the FPSIMD
state for tasks and KVM vcpus, this patch separates out the "cpu"
field that is used to track the cpu on which the state was most
recently loaded.

This will allow common code to operate on task and vcpu contexts
without requiring the cpu field to be stored at the same offset
from the FPSIMD register data in both cases.  This should avoid the
need for messing with the definition of those parts of struct
vcpu_arch that are exposed in the KVM user ABI.

The resulting change is also convenient for grouping and defining
the set of thread_struct fields that are supposed to be accessible
to copy_{to,from}_user(), which includes user_fpsimd_state but
should exclude the cpu field.  This patch does not amend the
usercopy whitelist to match: that will be addressed in a subsequent
patch.

7f170499f7 arm64: tlbflush: avoid writing RES0 bits
Several of the bits of the TLBI register operand are RES0 per the ARM
ARM, so TLBI operations should avoid writing non-zero values to these
bits.

This patch adds a macro __TLBI_VADDR(addr, asid) that creates the
operand register in the correct format and honors the RES0 bits.

dc6ed61d2f arm64: Add temporary ERRATA_MIDR_ALL_VERSIONS compatibility macro
MIDR_ALL_VERSIONS is changing, and won't have the same meaning
in 4.17, and the right thing to use will be ERRATA_MIDR_ALL_VERSIONS.

In order to cope with the merge window, let's add a compatibility
macro that will allow a relatively smooth transition, and that
can be removed post 4.17-rc1.

190e3138f9 Allwinner H3/H5 changes for 4.17
Here is our usual bunch of changes to the common DTSI shared between arm
 and arm64, and their associated device trees.
 
 Even though the diffstat is quite big, it's been mostly just cleanups. The
 big feature is that the HDMI is now suported on H3 and H5 boards.

c9406e514b arm64: move percpu cmpxchg implementation from cmpxchg.h to percpu.h
We want to avoid pulling linux/preempt.h into cmpxchg.h, since that can
introduce a circular dependency on linux/bitops.h. linux/preempt.h is
only needed by the per-cpu cmpxchg implementation, which is better off
alongside the per-cpu xchg implementation in percpu.h, so move it there
and add the missing #include.

e8a2d040fe arm64: cmpxchg: Include build_bug.h instead of bug.h for BUILD_BUG
Having asm/cmpxchg.h pull in linux/bug.h is problematic because this
ends up pulling in the atomic bitops which themselves may be built on
top of atomic.h and cmpxchg.h.

Instead, just include build_bug.h for the definition of BUILD_BUG.

f02e0468c4 Renesas ARM64 Based SoC DT Updates for v4.17
* R-Car Gen3 boards and SoCs
   - Make phy-mode of EtherAVB a board-specific property.
 
     The SoC DTs file now uses "rgmii" and boards override this with
     "rgmii-txid" as appropriate. Previously "rgmii-txid" was used
     in SoC DTs but this did not describe that more sophiticated
     functionality is a board rather than SoC property.
 
 * Condor board with R-Car V3H (r8a77980) SoC
   - Initial upstream support
 
 * Condor board with R-Car V3H (r8a77980) SoC
   - Initial upstream support
 
 * R-Car D3 (r8a77995)
   - Add I2C nodes and then describing the PCA9654 I/O expander connected to
     the I2C0 bus.
 
 * Eagle board with R-Car V3M (r8a77970) SoC
   - Enable PFC support for configuring SCIF0 pins
     This uses PFC support added to the V3M DT
 
   - Describe EtherAVB PHY IRQ
     This uses support for GPIO added to the V3M DT
 
   - Enable I2C0 support
 
     Sergei Shtylyov says "The I2C0 bus is populated by ON Semiconductor
     PCA9653 I/O expander and Analog Devices ADV7511W HDMI transmitter (but
     we're only describing the former chip now)."
 
 * R-Car V3M (r8a77970) SoCs
   - Add PFC support
   - Describe GPIO devices
   - Describe I2C devices
   - Srt subnodes of root node alphabetically to eas future maintence overhead
 
 * Draak board with R-Car D3 (r8a77995) SoC
   - Enable SDHI2
 
     Wolfram Sang says "The single SDHI controller is connected to eMMC."
 
   - Enable DU
 
     Kieran Bingham says "Enable the DU, providing only the VGA output for
     now."
 
 * R-Car D3 (r8a77995) and V3M (r8a77970) SoCs
   - Move nodes which have no reg property out of bus
     By deffinition the bus only has hardware with an address on the bus
 
   - Remove non-existing STBE region from EtherAVB
     Stream Buffer for EtherAVB-IF (STBE) is not present on these SoCs
 
 * R-Car D3 (r8a77995) SoC
   - Add FCPV, VSP and DU support
 
     Kieran Bingham says "The r8a77995-d3 platform supports 3 VSP instances.
     One VSPBS can be used as a dual-input image blender, while two VSPD
     instances can be utilised as part of a display (DU) pipeline.
 
     Add support for these, along with their required FCPV nodes."
 
 * Salvator-X and Salvator-XS boards with R-Car Gen3 SoCs
   - Add GPIO extender
     This is a basis for follow-up work to configure the GPIOs of the extender
 
 * Salvator-X and Salvator-XS board with R-Car M3-N (r8a77965) SoC
   - Initial upstream support
 
 * R-Car H3 (r8a7795) and M3-W (r8a7796) SoCs
   - Add OPPs table for cpu devices
     This, along with recently upstreamed Z and Z2 clock support allows
     use of CPUFreq with both A57 and A53 CPUs.
 
   - Add thermal cooling management
     Allows the use of CPUFreq as a cooling device on A57 CPUs
 
   - Correct register size of thermal node
 
     Niklas Söderlund says "To be able to read fused calibration values from
     hardware the size of the register resource of TSC1 needs to be
     incremented to cover one more register which holds the information if
     the calibration values have been fused or not.
 
     Instead of increasing TSC1 size to the value from the datasheet update
     all TSC's size to the smallest granularity of the address decoder
     circuitry"
 
   - Fix register mappings on VSPs
 
     Kieran Bingham says "The VSPD includes a CLUT on RPF2. Ensure that the
     register space is mapped correctly to support this."
 
 * R-Car H3 (r8a7795) SoC
   - Move SCIF node into alphabetical order to ease future maintenance overhead
 
   - Add IPMMU-PV1 device node
 
     This resolves an oversight when IPMMU nodes were added to the H3 DT.
     All IPMMU devices should now be described in DT.
 
   - Add missing SYS-DMAC2 dmas
 
     Geert Uytterhoeven says "On R-Car H3, on-chip peripheral modules that
     can make use of DMA are wired to either SYS-DMAC0 only, or to both
     SYS-DMAC1 and SYS-DMAC2.
 
     Add the missing DMA properties pointing to SYS-DMAC2 for HSCIF[0-2],
     SCIF[0125], and I2C[0-2].  These were initially left out because early
     firmware versions prohibited using SYS-DMAC2.  This restriction has
     been lifted in IPL and Secure Monitor Rev1.0.6 (released on Feb 25,
     2016)."

This reverts commit 1f85b42a69.

The internal dma-direct.h API has changed in -next, which collides with
us trying to use it to manage non-coherent DMA devices on systems with
unreasonably large cache writeback granules.

This isn't at all trivial to resolve, so revert our changes for now and
we can revisit this after the merge window. Effectively, this just
restores our behaviour back to that of 4.16.

ece1397cbc arm64: Add work around for Arm Cortex-A55 Erratum 1024718
Some variants of the Arm Cortex-55 cores (r0p0, r0p1, r1p0) suffer
from an erratum 1024718, which causes incorrect updates when DBM/AP
bits in a page table entry is modified without a break-before-make
sequence. The work around is to skip enabling the hardware DBM feature
on the affected cores. The hardware Access Flag management features
is not affected. There are some other cores suffering from this
errata, which could be added to the midr_list to trigger the work
around.

05abb595bb arm64: Delay enabling hardware DBM feature
We enable hardware DBM bit in a capable CPU, very early in the
boot via __cpu_setup. This doesn't give us a flexibility of
optionally disable the feature, as the clearing the bit
is a bit costly as the TLB can cache the settings. Instead,
we delay enabling the feature until the CPU is brought up
into the kernel. We use the feature capability mechanism
to handle it.

The hardware DBM is a non-conflicting feature. i.e, the kernel
can safely run with a mix of CPUs with some using the feature
and the others don't. So, it is safe for a late CPU to have
this capability and enable it, even if the active CPUs don't.

To get this handled properly by the infrastructure, we
unconditionally set the capability and only enable it
on CPUs which really have the feature. Also, we print the
feature detection from the "matches" call back to make sure
we don't mislead the user when none of the CPUs could use the
feature.
