Linus Torvalds e09d51adfb ARM: SoC fixes
A few more fixes that have come in, and one revert of a previous fix.
 
 I was a bit too trigger happy to enable PREEMPT on multi_v7_defconfig,
 and it ended up regressing at least BeagleBone XM boards. While we get
 that debugged for next merge window, let's disable it again.
 
 Beyond that:
 
  - Stratix change to fix multicast filtering
  - Minor DT fixes for Renesas and i.MX
  - Ethernet fix for a Renesas board (switching main interfaces)
  - Ethernet phy regulator fix for i.MX6SX

  ARM: 8809/1: proc-v7: fix Thumb annotation of cpu_v7_hvc_switch_mm

Ard Biesheuvel 6282e916f7 ARM: 8809/1: proc-v7: fix Thumb annotation of cpu_v7_hvc_switch_mm
Due to what appears to be a copy/paste error, the opening ENTRY()
of cpu_v7_hvc_switch_mm() lacks a matching ENDPROC(), and instead,
the one for cpu_v7_smc_switch_mm() is duplicated.

Given that it is ENDPROC() that emits the Thumb annotation, the
cpu_v7_hvc_switch_mm() routine will be called in ARM mode on a
Thumb2 kernel, resulting in the following splat:

  Internal error: Oops - undefined instruction: 0 [#1] SMP THUMB2

Leonard Crestez 1ad9fb750a ARM: dts: imx6sx-sdb: Fix enet phy regulator
Bindings for "fixed-regulator" only explicitly support "gpio" property,
not "gpios". Fix by correcting the property name.

The enet PHYs on imx6sx-sdb needs to be explicitly reset after a power
cycle, this can be handled by the phy-reset-gpios property. Sadly this
is not handled on suspend: the fec driver turns phy-supply off but
doesn't assert phy-reset-gpios again on resume.

Since additional phy-level work is required to support powering off the
phy in suspend fix the problem by just marking the regulator as
"boot-on" "always-on" so that it's never turned off. This behavior is
equivalent to older releases.

Keep the phy-reset-gpios property on fec anyway because it is a correct
description of board design.

This issue was exposed by commit efdfeb079c ("regulator: fixed:
Convert to use GPIO descriptor only") which causes the "gpios" property
to also be parsed. Before that commit the "gpios" property had no
effect, PHY reset was only handled in the the bootloader.

This fixes linux-next boot failures previously reported here:

Rob Herring 1af6ab3bac ARM: dts: fsl: Fix improperly quoted stdout-path values
A quoted label reference doesn't expand to the node path and is taken as
a literal string. Dropping the quotes can fix this unless the baudrate
string is appended in which case we have to use the alias.

At least on VF610, the problem was masked by setting the console in
bootargs. Use the alias syntax with baudrate parameter so we can drop
setting the console in bootargs.

Linus Torvalds 519f64bf15 This time it looks like a quieter release cycle in the clk tree. I guess that's
because of summer time holidays/vacations. The biggest change in the diffstat
 is in the Qualcomm clk driver, where they got support for CPUs and handful of
 SoCs. After that, the at91 driver got a major rewrite for newer DT bindings
 that should make things easier going forward and the TI code moved to a
 clockdomain based design. The long tail is mostly small driver updates for
 newer clks and some simpler SoC clock drivers such as the Hisilicon and imx
 support.
 
 In the core framework, we only have two small changes this time. One is a new
 clk API to get all clks for a device with the bulk clk APIs. This allows
 drivers that don't care about doing anything besides turning on all the clks to
 just clk_get() them all and turn them on. The other change is the beginning of
 a way to support save and restore of clk settings in the clk framework. TI is
 the only user right now, but we will want to expand upon this design in the
 future to support more save and restore of clk registers.  At least this gets
 us started and works well enough for one SoC, but there's more work in the
 future.
 
 Core:
  - clk_bulk_get_all() API and friends to get all the clks for a device
  - Basic clk state save/restore hooks
 
 New Drivers:
  - Renesas RZ/A2 (R7S9210) SoC, including early clocks
  - Rensas RZ/G1N (R8A7744) and RZ/G2E (R8A774C0) SoCs
  - Rensas RZ/G2M (r8a774a1) SoC
  - Qualcomm Krait CPU clk support
  - Qualcomm QCS404 GCC support
  - Qualcomm SDM660 GCC support

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
 "This time it looks like a quieter release cycle in the clk tree. I
  guess that's because of summer time holidays/vacations. The biggest
  change in the diffstat is in the Qualcomm clk driver, where they got
  support for CPUs and handful of SoCs. After that, the at91 driver got
  a major rewrite for newer DT bindings that should make things easier
  going forward and the TI code moved to a clockdomain based design.

  The long tail is mostly small driver updates for newer clks and some
  simpler SoC clock drivers such as the Hisilicon and imx support.

  In the core framework, we only have two small changes this time.

  One is a new clk API to get all clks for a device with the bulk clk
  APIs. This allows drivers that don't care about doing anything besides
  turning on all the clks to just clk_get() them all and turn them on.

  The other change is the beginning of a way to support save and restore
  of clk settings in the clk framework. TI is the only user right now,
  but we will want to expand upon this design in the future to support
  more save and restore of clk registers. At least this gets us started
  and works well enough for one SoC, but there's more work in the
  future.

  Core:
   - clk_bulk_get_all() API and friends to get all the clks for a device
   - Basic clk state save/restore hooks

  New Drivers:
   - Renesas RZ/A2 (R7S9210) SoC, including early clocks

Mike Rapoport 7e1c4e2792 memblock: stop using implicit alignment to SMP_CACHE_BYTES
When a memblock allocation APIs are called with align = 0, the alignment
is implicitly set to SMP_CACHE_BYTES.

Implicit alignment is done deep in the memblock allocator and it can
come as a surprise.  Not that such an alignment would be wrong even
when used incorrectly but it is better to be explicit for the sake of
clarity and the prinicple of the least surprise.

Replace all such uses of memblock APIs with the 'align' parameter
explicitly set to SMP_CACHE_BYTES and stop implicit alignment assignment
in the memblock internal allocation functions.

For the case when memblock APIs are used via helper functions, e.g.  like
iommu_arena_new_node() in Alpha, the helper functions were detected with
Coccinelle's help and then manually examined and updated where
appropriate.

The direct memblock APIs users were updated using the semantic patch below:

Mike Rapoport b4a991ec58 mm: remove CONFIG_NO_BOOTMEM
All achitectures select NO_BOOTMEM which essentially becomes 'Y' for any
kernel configuration and therefore it can be removed.

Nick Desaulniers de0d22e50c treewide: remove current_text_addr
Prefer _THIS_IP_ defined in linux/kernel.h.

Most definitions of current_text_addr were the same as _THIS_IP_, but
a few archs had inline assembly instead.

This patch removes the final call site of current_text_addr, making all
of the definitions dead code.

Linus Torvalds 4b42745211 ARM: SoC platform updates for 4.20
A couple of platforms change hands in the MAINTAINERS file:
 
 - Linus Walleij lists himself for the ARM Reference platforms:
   versatile, vexpress, integrator and realview. He has been the main
   contributor for these for a while, and makes it official now.
 
 - Vladimir Zapolskiy takes over the LPC18xx platform from Joachim Eastwood
 
 - Manivannan Sadhasivam becomes a secondary maintainer for the
   Actions Semi machines
 
 - Nicolas Ferre lists updates the MAINTAINER listing for the AT91
   platform: Ludovic Desroches is now a co-maintainer for the platform, and
   several other people (Claudiu Beznea, Cristian Birsan, Eugen Hristev,
   Codrin Ciubotariu) take over individual device drivers.
 
 Thanks everyone for working on this, and welcome to the new maintainers!
 
 The "virt" platform on qemy or kvm can now be used in big-endian mode
 without additional tricks, thanks to Jason Donenfeld.
 
 Once again, we gain support for another NXP i.MX6 variant, this time
 it's the i.MX 6ULZ 32-bit single-core version.
 
 On arm64, we add support for two SoCs from Renesas: RZ/G2E (r8a774c0)
 and RZ/G2M (r8a774a1). These are described as microcontrollers on the
 manufacturer website, but appear to be rather powerful. The RZ/G2M is
 used on the reference board for the CIP Super Long Term Support (SLTS)
 Linux Kernels.

Linus Torvalds b22b6beae6 ARM: SoC driver updates for 4.17
The most noteworthy SoC driver changes this time include:
 
 - The TEE subsystem gains an in-kernel interface to access the TEE
   from device drivers.
 
 - The reset controller subsystem gains a driver for the Qualcomm
   Snapdragon 845 Power Domain Controller.
 
 - The Xilinx Zynq platform now has a firmware interface for its
   platform management unit. This contains a firmware "ioctl" interface
   that was a little controversial at first, but the version we merged
   solved that by not exposing arbitrary firmware calls to user space.
 
 - The Amlogic Meson platform gains a "canvas" driver that is used
   for video processing and shared between different high-level drivers.
 
 The rest is more of the usual, mostly related to SoC specific power
 management support and core drivers in drivers/soc:
 
 - Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
   features related to power and reset control.
 
 - The Mediatek mt8183 and mt6765 SoC platforms gain support for
   their respective power management chips.
 
 - A new driver for NXP i.MX8, which need a firmware interface for
   power management.
 
 - The SCPI firmware interface now contains support estimating power
   usage of performance states
 
 - The NVIDIA Tegra "pmc" driver gains a few new features, in particular
   a pinctrl interface for configuring the pads.
 
 - Lots of small changes for Qualcomm, in particular the "smem"
   device driver.
 
 - Some cleanups for the TI OMAP series related to their sysc
   controller.
 
 Additional cleanups and bugfixes in SoC specific drivers include the
 Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms.

Linus Torvalds 93335e5911 ARM: SoC device tree updates for 4.20
There are close to 800 indivudal changesets in this branch again, which
 feels like a lot. There are particularly many changes for the NVIDIA
 Tegra platform this time, in fact more than it has seen in the two years
 since the v4.9 merge window. Aside from this, it's been fairly normal,
 with lots of changes going into Renesas R-CAR, NXP i.MX, Allwinner Sunxi,
 Samsung Exynos, and TI OMAP.
 
 Most of the changes are for adding new features into existing boards,
 for brevity I'm only mentioning completely new machines and SoCs here.
 For the first time I think we have (slightly) more new 64-bit hardware
 than 32-bit:
 
 Two boards get added for TI OMAP: Moxa UC-2101 is an industrial
 computer, see https://www.moxa.com/product/UC-2100.htm; GTA04A5
 is a minor variation of the motherboards of the GTA04 phone, see
 https://shop.goldelico.com/wiki.php?page=GTA04A5
 
 Clearfog is a nice little board for quad-core
 Marvell Armada 8040 network processor, see
 https://www.solid-run.com/marvell-armada-family/clearfog-gt-8k/
 
 Two additional server boards come with the Aspeed baseboard management
 controllers: Stardragon4800 is an arm64 reference platform made by HXT
 (based on Qualcomm's server chips), and TiogaPass is an Open Compute
 mainboard with x86 CPUs. Both use the ARM11 based AST2500 chips in
 the BMC.
 
 NXP i.MX usually sees a lot of new boards each release. This time there
 we only add one minor variant: ConnectCore 6UL SBC Pro uses the same
 SoM design as the ConnectCore 6UL SBC Express added later. However,
 there is a new chip, the i.MX6ULZ, which is an even smaller variant
 of the i.MX6ULL, with features removed. There is also support for the
 reference board design, the i.MX6ULZ 14x14 EVK.
 
 A new Raspberry Pi variant gets added, this one is the CM3 compute module
 based on bcm2837, it was launched in early 2017 but only now added to
 the kernel, both as 32-bit and as 64-bit files, as we tend to do for
 Raspberry Pi.
 
 On the Allwinner side, everything is again about cheap development
 boards, usually of the "Fruit Pi" variety. The new ones this time
 are:
 Orange Pi Zero Plus2: http://www.orangepi.org/OrangePiZeroPlus2/
 Orange Pi One Plus: http://www.orangepi.org/OrangePiOneplus/
 Pine64 LTS: https://www.pine64.org/?product=pine-a64-lts
 Banana Pi M2+ H5: http://www.banana-pi.org/m2plus.html
 The last one of these is now a 64-bit version of the earlier Banana
 Pi M2+ H3, with the same board layout.
 
 Similarly, for Rockchips, get get another variant of the 32-bit
 Asus Tinker board, the model 'S' based on rk3288, and three now
 boards based on the popular RK3399 chip:
 ROC-RK3399-PC: https://libre.computer/products/boards/roc-rk3399-pc/
 Rock960: https://www.96boards.org/product/rock960/
 RockPro64: https://www.pine64.org/?page_id=61454
 These are all quite powerful boards with lots of RAM and I/O, and
 the RK3399 is the same chip used in several Chromebooks.  Finally,
 we get support for the PX30 (aka rk3326) chip, which is based on the
 low-end 64-bit Cortex-A35 CPU core. So far, only the evaluation board
 is supported.
 
 One more Banana Pi is added with a Mediatek chip: Banana Pi R64 is based
 on the MT7622 WiFi router platform, and the first product I've seen with
 a 64-bit Mediatek chip in that market: http://www.banana-pi.org/r64.html
 
 For HiSilicon, we gain support for the Hi3670 SoC and HiKey 370
 development board, which are similar to the Hi3660 and Hikey 360
 respectively, but add support for an NPU.
 
 Amlogic gets initial support for the Meson-G12A chip (S905D2),
 another quad-core Cortex-A53 SoC, and its evaluation platform.
 On the 32-bit side, we gain support for an actual end-user product,
 the Endless Computers Endless Mini based on Meson8b (S805), see
 https://endlessos.com/computers/
 
 Qualcomm adds support for their MSM8998 SoC and evaluation platform. This
 chip is commonly known as the Snapdragon 835, and is used in high-end
 phones as well as low-end laptops.
 
 For Renesas, a very bare support for the r8a774a1 (RZ/G2M) is added,
 but no boards for this one. However, we do add boards for the previously
 added r8a77965 (R-Car M3-N): the M3NULCB Kingfisher and the M3NULCB
 Starter Kit Pro.
 
 While we have lots of DT changes for NVIDIA to update the existing files,
 the only board that gets added is the Toradex Colibri T20 on Colibri
 Evaluation Board for the old Tegra2.
 
 Synaptics add support for their AS370 SoC, which is part of the (formerly
 Marvell) Berlin line of set-top-box chips used e.g.  in the various Google
 Chromecast. Only the .dtsi gets added at this point, no actual machines.

Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC device tree updates from Arnd Bergmann:
 "There are close to 800 indivudal changesets in this branch again,
  which feels like a lot. There are particularly many changes for the
  NVIDIA Tegra platform this time, in fact more than it has seen in the
  two years since the v4.9 merge window. Aside from this, it's been
  fairly normal, with lots of changes going into Renesas R-CAR, NXP
  i.MX, Allwinner Sunxi, Samsung Exynos, and TI OMAP.

  Most of the changes are for adding new features into existing boards,
  for brevity I'm only mentioning completely new machines and SoCs here.
  For the first time I think we have (slightly) more new 64-bit hardware
  than 32-bit:

  Two boards get added for TI OMAP: Moxa UC-2101 is an industrial
  computer, see https://www.moxa.com/product/UC-2100.htm; GTA04A5 is a
  minor variation of the motherboards of the GTA04 phone, see
  https://shop.goldelico.com/wiki.php?page=GTA04A5

  Clearfog is a nice little board for quad-core Marvell Armada 8040
  network processor, see
  https://www.solid-run.com/marvell-armada-family/clearfog-gt-8k/

  Two additional server boards come with the Aspeed baseboard management
  controllers: Stardragon4800 is an arm64 reference platform made by HXT
  (based on Qualcomm's server chips), and TiogaPass is an Open Compute
  mainboard with x86 CPUs. Both use the ARM11 based AST2500 chips in the
  BMC.

  NXP i.MX usually sees a lot of new boards each release. This time
  there we only add one minor variant: ConnectCore 6UL SBC Pro uses the
  same SoM design as the ConnectCore 6UL SBC Express added later.
  However, there is a new chip, the i.MX6ULZ, which is an even smaller
  variant of the i.MX6ULL, with features removed. There is also support
  for the reference board design, the i.MX6ULZ 14x14 EVK.

  A new Raspberry Pi variant gets added, this one is the CM3 compute
  module based on bcm2837, it was launched in early 2017 but only now
  added to the kernel, both as 32-bit and as 64-bit files, as we tend to
  do for Raspberry Pi.

  On the Allwinner side, everything is again about cheap development
  boards, usually of the "Fruit Pi" variety. The new ones this time are:
   - Orange Pi Zero Plus2: http://www.orangepi.org/OrangePiZeroPlus2/
   - Orange Pi One Plus: http://www.orangepi.org/OrangePiOneplus/
   - Pine64 LTS: https://www.pine64.org/?product=pine-a64-lts
   - Banana Pi M2+ H5: http://www.banana-pi.org/m2plus.html
  The last one of these is now a 64-bit version of the earlier Banana Pi
  M2+ H3, with the same board layout.

  Similarly, for Rockchips, get get another variant of the 32-bit Asus
  Tinker board, the model 'S' based on rk3288, and three now boards
  based on the popular RK3399 chip:
   - ROC-RK3399-PC: https://libre.computer/products/boards/roc-rk3399-pc/
   - Rock960: https://www.96boards.org/product/rock960/
   - RockPro64: https://www.pine64.org/?page_id=61454
  These are all quite powerful boards with lots of RAM and I/O, and the
  RK3399 is the same chip used in several Chromebooks. Finally, we get
  support for the PX30 (aka rk3326) chip, which is based on the low-end
  64-bit Cortex-A35 CPU core. So far, only the evaluation board is
  supported.

  One more Banana Pi is added with a Mediatek chip: Banana Pi R64 is
  based on the MT7622 WiFi router platform, and the first product I've
  seen with a 64-bit Mediatek chip in that market:
  http://www.banana-pi.org/r64.html

  For HiSilicon, we gain support for the Hi3670 SoC and HiKey 370
  development board, which are similar to the Hi3660 and Hikey 360
  respectively, but add support for an NPU.

  Amlogic gets initial support for the Meson-G12A chip (S905D2), another
  quad-core Cortex-A53 SoC, and its evaluation platform. On the 32-bit
  side, we gain support for an actual end-user product, the Endless
  Computers Endless Mini based on Meson8b (S805), see
  https://endlessos.com/computers/

  Qualcomm adds support for their MSM8998 SoC and evaluation platform.
  This chip is commonly known as the Snapdragon 835, and is used in
  high-end phones as well as low-end laptops.

  For Renesas, a very bare support for the r8a774a1 (RZ/G2M) is added,
  but no boards for this one. However, we do add boards for the
  previously added r8a77965 (R-Car M3-N): the M3NULCB Kingfisher and the
  M3NULCB Starter Kit Pro.

  While we have lots of DT changes for NVIDIA to update the existing
  files, the only board that gets added is the Toradex Colibri T20 on
  Colibri Evaluation Board for the old Tegra2.

  Synaptics add support for their AS370 SoC, which is part of the
  (formerly Marvell) Berlin line of set-top-box chips used e.g. in the
  various Google Chromecast. Only the .dtsi gets added at this point, no
  actual machines"

Linus Torvalds b27186abb3 Devicetree updates for 4.20:
- Sync dtc with upstream version v1.4.7-14-gc86da84d30e4
 
 - Work to get rid of direct accesses to struct device_node name and
   type pointers in preparation for removing them. New helpers for
   parsing DT cpu nodes and conversions to use the helpers. printk
   conversions to %pOFn for printing DT node names. Most went thru
   subystem trees, so this is the remainder.
 
 - Fixes to DT child node lookups to actually be restricted to child
   nodes instead of treewide.
 
 - Refactoring of dtb targets out of arch code. This makes the support
   more uniform and enables building all dtbs on c6x, microblaze, and
   powerpc.
 
 - Various DT binding updates for Renesas r8a7744 SoC
 
 - Vendor prefixes for Facebook, OLPC
 
 - Restructuring of some ARM binding docs moving some peripheral bindings
   out of board/SoC binding files
 
 - New "secure-chosen" binding for secure world settings on ARM
 
 - Dual licensing of 2 DT IRQ binding headers

Linus Torvalds ba9f6f8954 Merge branch 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull siginfo updates from Eric Biederman:
 "I have been slowly sorting out siginfo and this is the culmination of
  that work.

  The primary result is in several ways the signal infrastructure has
  been made less error prone. The code has been updated so that manually
  specifying SEND_SIG_FORCED is never necessary. The conversion to the
  new siginfo sending functions is now complete, which makes it
  difficult to send a signal without filling in the proper siginfo
  fields.

  At the tail end of the patchset comes the optimization of decreasing
  the size of struct siginfo in the kernel from 128 bytes to about 48
  bytes on 64bit. The fundamental observation that enables this is by
  definition none of the known ways to use struct siginfo uses the extra
  bytes.

  This comes at the cost of a small user space observable difference.
  For the rare case of siginfo being injected into the kernel only what
  can be copied into kernel_siginfo is delivered to the destination, the
  rest of the bytes are set to 0. For cases where the signal and the
  si_code are known this is safe, because we know those bytes are not
  used. For cases where the signal and si_code combination is unknown
  the bits that won't fit into struct kernel_siginfo are tested to
  verify they are zero, and the send fails if they are not.

  I made an extensive search through userspace code and I could not find
  anything that would break because of the above change. If it turns out
  I did break something it will take just the revert of a single change
  to restore kernel_siginfo to the same size as userspace siginfo.

  Testing did reveal dependencies on preferring the signo passed to
  sigqueueinfo over si->signo, so bit the bullet and added the
  complexity necessary to handle that case.

  Testing also revealed bad things can happen if a negative signal
  number is passed into the system calls. Something no sane application
  will do but something a malicious program or a fuzzer might do. So I
  have fixed the code that performs the bounds checks to ensure negative
  signal numbers are handled"
