ARM: sunxi: Fix CPU powerdown on A83T
PRCM_PWROFF_GATING_REG has CPU0 at bit 4 on A83T. So without this
patch, instead of gating the CPU0, the whole cluster was power gated,
when shutting down first CPU in the cluster.

ARM: dts: sun8i-a83t-tbs-a711: Fix WiFi resume from suspend
Without enabling keep-power-in-suspend, we can't wake the device
up using WOL packet, and the log is flooded with these messages
on resume:
sunxi-mmc 1c10000.mmc: send stop command failed
sunxi-mmc 1c10000.mmc: data error, sending stop command
sunxi-mmc 1c10000.mmc: send stop command failed
sunxi-mmc 1c10000.mmc: data error, sending stop command
So to make the WiFi really a wakeup-source, we need to keep it powered
during suspend.

ARM: dts: sun7i: Drop the module clock from the device tree
What we thought would be the module clock is actually the clock meant to be
used by the sensors, and play no role in the CSI controller. Now that the
binding has been updated to reflect that, let's update the device tree too.

mm: treewide: clarify pgtable_page_{ctor,dtor}() naming
The naming of pgtable_page_{ctor,dtor}() seems to have confused a few
people, and until recently arm64 used these erroneously/pointlessly for
other levels of page table.
To make it incredibly clear that these only apply to the PTE level, and to
align with the naming of pgtable_pmd_page_{ctor,dtor}(), let's rename them
to pgtable_pte_page_{ctor,dtor}().
These changes were generated with the following shell script:
----
git grep -lw 'pgtable_page_.tor' | while read FILE; do
sed -i '{s/pgtable_page_ctor/pgtable_pte_page_ctor/}' $FILE;
sed -i '{s/pgtable_page_dtor/pgtable_pte_page_dtor/}' $FILE;
done
----
... with the documentation re-flowed to remain under 80 columns, and
whitespace fixed up in macros to keep backslashes aligned.
There should be no functional change as a result of this patch.

arm: use generic mmap top-down layout and brk randomization
arm uses a top-down mmap layout by default that exactly fits the generic functions, so get rid of arch specific code and use the generic version by selecting ARCH_WANT_DEFAULT_TOPDOWN_MMAP_LAYOUT. As ARCH_WANT_DEFAULT_TOPDOWN_MMAP_LAYOUT selects ARCH_HAS_ELF_RANDOMIZE, use the generic version of arch_randomize_brk since it also fits. Note that this commit also removes the possibility for arm to have elf randomization and no MMU: without MMU, the security added by randomization is worth nothing. Note that it is safe to remove STACK_RND_MASK since it matches the default value.

mm: consolidate pgtable_cache_init() and pgd_cache_init()
Both pgtable_cache_init() and pgd_cache_init() are used to initialize kmem cache for page table allocations on several architectures that do not use PAGE_SIZE tables for one or more levels of the page table hierarchy. Most architectures do not implement these functions and use __weak default NOP implementation of pgd_cache_init(). Since there is no such default for pgtable_cache_init(), its empty stub is duplicated among most architectures. Rename the definitions of pgd_cache_init() to pgtable_cache_init() and drop empty stubs of pgtable_cache_init().

mm: remove quicklist page table caches
Patch series "mm: remove quicklist page table caches". A while ago Nicholas proposed to remove quicklist page table caches [1]. I've rebased his patch on the curren upstream and switched ia64 and sh to use generic versions of PTE allocation. [1] https://lore.kernel.org/linux-mm/20190711030339.20892-1-npiggin@gmail.com This patch (of 3): Remove page table allocator "quicklists". These have been around for a long time, but have not got much traction in the last decade and are only used on ia64 and sh architectures. The numbers in the initial commit look interesting but probably don't apply anymore. If anybody wants to resurrect this it's in the git history, but it's unhelpful to have this code and divergent allocator behaviour for minor archs. Also it might be better to instead make more general improvements to page allocator if this is still so slow.

ARM: SoC: late updates for v5.4
This is some material that we picked up into our tree late or
that had complex inter-depondencies. The fact that there are these
interdependencies tends to meant that these are often actually the most
interesting new additions:
The new Aspeed AST2600 baseboard management controller is added, this
is a Cortex-A7 based follow-up to the ARM11 based AST2500 and had some
dependencies on other device drivers.
After many years, support for the MMP2 based OLPC XO-1.75 finally makes
it into the kernel.
The Armada 3720 based Turris Mox open source router platform is a late
addition and it follows some preparatory work across multiple branches.
The OMAP2+ platform had some large-scale cleanup involving driver
changes and DT changes, here we finish it off, dropping a lot of the
now-unused platform data.
The TI K3 platform that got added for 5.3 gains a lot more support
for individual bits on the SoC, this part just came late for the
merge window.

ARM: aspeed: ast2500 is ARMv6K
Linux supports both the original ARMv6 level (early ARM1136) and ARMv6K
(later ARM1136, ARM1176 and ARM11mpcore).
ast2500 falls into the second categoy, being based on arm1176jzf-s.
This is enabled by default when using ARCH_MULTI_V6, so we should
not 'select CPU_V6'.
Removing this will lead to more efficient use of atomic instructions.
Fixes:

USB changes for 5.4-rc1
Here is the big set of USB patches for 5.4-rc1. Two major chunks of code are moving out of the tree and into the staging directory, uwb and wusb (wireless USB support), because there are no devices that actually use this protocol anymore, and what we have today probably doesn't work at all given that the maintainers left many many years ago. So move it to staging where it will be removed in a few releases if no one screams. Other than that, lots of little things. The usual gadget and xhci and usb serial driver updates, along with a bunch of sysfs file cleanups due to the driver core changes to support that. Nothing really major, just constant forward progress. All of these have been in linux-next for a while with no reported issues.

sound updates for 5.4
As shown in diffstat and logs, it was again a busy development
cycle at this time, too. The most significant changes are still
on-going refactoring / modernization works for ASoC core and
drivers, but there are lots of other changes as well. Here we go,
some highlights below:
ASoC:
- Quite lots of cleanup / refactoring of ASoC core and APIs;
most of them are systematic, but also including cleanups and
modernization
- A bulk of updates for some ASoC platforms, Freescale, sunxi and
Intel SST/SOF
- Initial support for Sound Open Firmware on i.MX8
- Removal of deprecated w90x900 and nuc900 drivers
- New support for Cirrus Logic CS47L15 and CS47L92, Freescale i.MX
7ULP and 8MQ, Meson G12A and NXP UDA1334
USB-audio:
- More validations of descriptor units for hardening against bugs
reported by fuzzers
- PCM device assignment workaround for a past call-order change
- Scarlett Gen2 mixer interface, a few more more quirks
HD-audio:
- Support for audio component with AMD/ATI and Nvidia HDMI codecs
- Clean up HD-audio core and remove indirect access ops for Intel SOF
- DMIC detection at probe; it would make systems automatically falling
back to SST/SOF driver on devices that need DMIC handling.
Needs a new Kconfig to set, and beware that it's still new and a bit
experimental
FireWire:
- Lots of code refactoring and cleanups

ARM: DT updates for v5.4
This is another huge branch with close to 450 changessets related to
devicetree files, roughly half of this for 32-bit and 64-bit respectively.
There are lots of cleanups and additional hardware support for platforms
we already support based on SoCs from Renesas, ST-Microelectronics,
Intel/Altera, Rockchips, Allwinner, Broadcom and other manufacturers.
A total of 6 new SoCs and 37 new boards gets added this time, one more
SoC will come in a follow-up branch. Most of the new boards are for
64-bit ARM SoCs, the others are typically for the 32-bit Cortex-A7.
Going more into details for SoC platforms with new hardware support:
The Snapdragon 855 (SM8150) is Qualcomm's current high-end phone platform,
usually paired with an external 5G modem. So far we only support the
Qualcomm SM8150 MTP reference platform, but no actual products.
For the slightly older Qualcomm platforms, support for several interesting
products is getting added: Three laptops based on Snapdragon 835/MSM8998
(Asus NovaGo, HP Envy X2 and Lenovo Miix 630), one laptop based on
Snapdragon 850/sdm850 (Lenovo Yoga C630) and several phones based on
the older Snapdragon 410/MSM8916 (Samsung A3 and A5, Longcheer L8150
aka Android One 2nd gen "seed" aka Wileyfox Swift).
Mediatek MT7629 is a new wireless network router chip, similar to
the older MT7623. It gets added together with the reference board
implementation.
Allwinner V3 is a repackaged version of the existing low-end V3s chip,
and is used in the tiny Lichee Pi Zero plus, also added here. There is
also a new TV set-top box based on Allwinner H6, the Tanix TX6, and the
eMMC variant of the Olimex A64-Olinuxino development board.
NXP i.MX8M Nano is a new member of the ever-expanding i.MX SoC family,
similar to the i.MX8M Mini. As usual, there is a large number of new
boards for i.MX SoCs: Einfochips i.MX8QXP AI_ML, SolidRun Hummingboard
Pulse baseboard and System-on-Module, Boundary Devices i.MX8MQ Nitrogen8M,
and TechNexion PICO-PI-IMX8M-DEV for the 64-bit i.MX8 line. For 32-bit,
we get the Kontron i.MX6UL N6310 SoM with two baseboards, the PHYTEC
phyBOARD-Segin SoM with three baseboards, and the Zodiac Inflight
Innovations i.MX7 RMU2 board.
In a different NXP product line, the Layerscape LS1046A "Freeway"
reference board gets added.
Amlogic SM1 (S905X3) and G12B (S922X, A311D) are updated chips from their
set-top-box line and smart speaker with newer CPU and GPU cores compared
to their predecessors. Both are now also supported by the Khadas VIM3
development board series, and the dts files for that get reorganized a
bit to better deal with all variants. Another board based on SM1 that
gets added is the SEI Robotics SEI610.
There are a handful of new x86 and Power9 server boards using Aspeed BMC
chips that are gaining support for running Linux on the BMC through the
OpenBMC project: Facebook Minipack/Wedge100/Wedge40, Lenovo Hr855xg2,
and Mihawk. Notably these are still new machines using SoCs based on
the ARM9 and ARM11 CPU cores, as support for the new Cortex-A7 based
AST2600 is still ramping up.
There are three new end-user products using 32-bit Rockchips SoCs:
Mecer Xtreme Mini S6 is an Android "mini PC" box based on the low-end
RK3229 chip, while the two AOpen products Chromebox Mini (Fievel) and
Chromebase Mini (Tiger) run ChromeOS and are meant for commercial settings
(digital signage, PoS, ...).
One more single-board computer based on the popular 64-bit RK3399 is
added: the Leez RK3399 P710.

ARM: SoC driver updates for v5.4
The branch contains driver changes that are tightly
connected to SoC specific code. Aside from smaller
cleanups and bug fixes, here is a list of the notable
changes.
New device drivers:
- The Turris Mox router has a new "moxtet" bus driver
for its on-board pluggable extension bus. The
same platform also gains a firmware driver.
- The Samsung Exynos family gains a new Chipid driver
exporting using the soc device sysfs interface
- A similar socinfo driver for Qualcomm Snapdragon
chips.
- A firmware driver for the NXP i.MX DSP IPC protocol
using shared memory and a mailbox
Other changes:
- The i.MX reset controller driver now supports the
NXP i.MX8MM chip
- Amlogic SoC specific drivers gain support for
the S905X3 and A311D chips
- A rework of the TI Davinci framebuffer driver to
allow important cleanups in the platform code
- A couple of device drivers for removed ARM SoC
platforms are removed. Most of the removals were
picked up by other maintainers, this contains
whatever was left.

ARM: SoC platform updates for v5.4
The main change this time around is a cleanup of some of the oldest platforms based on the XScale and ARM9 CPU cores, which are between 10 and 20 years old. The Kendin/Micrel/Microchip KS8695, Winbond/Nuvoton W90x900 and Intel IOP33x/IOP13xx platforms are removed after we determined that nobody is using them any more. The TI Davinci and NXP LPC32xx platforms on the other hand are still in active use and are converted to the ARCH_MULTIPLATFORM build, meaning that we can compile a kernel that works on these along with most other ARMv5 platforms. Changes toward that goal are also merged for IOP32x, but additional work is needed to complete this. Patches for the remaining ARMv5 platforms have started but need more work and some testing. Support for the new ASpeed AST2600 gets added, this is based on the Cortex-A7 ARMv7 core, and is a newer version of the existing ARMv5 and ARMv6 chips in the same family. Other changes include a cleanup of the ST-Ericsson ux500 platform and the move of the TI Davinci platform to a new clocksource driver.

Pull arm64 updates from Will Deacon:
"Although there isn't tonnes of code in terms of line count, there are
a fair few headline features which I've noted both in the tag and also
in the merge commits when I pulled everything together.
The part I'm most pleased with is that we had 35 contributors this
time around, which feels like a big jump from the usual small group of
core arm64 arch developers. Hopefully they all enjoyed it so much that
they'll continue to contribute, but we'll see.
It's probably worth highlighting that we've pulled in a branch from
the risc-v folks which moves our CPU topology code out to where it can
be shared with others.
Summary:
- 52-bit virtual addressing in the kernel
- New ABI to allow tagged user pointers to be dereferenced by

This is the bulk of changes in the GPIO subsystem for the
v5.4 kernel cycle.
Core changes:
- Support hierarchical GPIO irqchips. We now have three
consumers that can use this: Intel IXP4xx, ThunderX and
Qualcomm SPMI GPIO (in the pinctrl subsystem). The support
code has been long in the making and hashed out so it should
be easily adaptable for all hierarchical irqchip parents.
The code only gets compiled in if hierarchical irqchip
is used at the topmost irq controller at least, as the
hierarchical irqchip requires strict hierarchy all the
way up in the system.
- Determine the need for a "valid_mask" for GPIO lines on the
gpio_chip and conversely for the "valid_mask" for the GPIO
interrupt chip interrupt lines by looking for a
.init_valid_mask() callback in the main chip or GPIO interrupt
chip respectively. Allocate it with bitmap_alloc().
- Isolate the device tree/open firmware GPIO description code
out in its own file properly.
- Isolate the ACPI GPIO description code out in its own file
properly.
- Drop a whole lot of #ifdef:s in the main includes: it does
not hurt to keep the include items around, and we get
quicker and clearer compile failures if the appropriate
kernel symbols are not selected for drivers.
New/deleted drivers:
- New driver for Aspeed SGPIO.
- The KS8695 driver is deleted as the platform gets deleted
from arch/arm in this kernel cycle.
- The Cirrus Logic Madera driver now supports CS47L92 and
CS47L15.
- The Freescale MPC8xxx now supports LS1028A and LS1088A.
Driver improvements:
- We pass the GPIO irqchip intialization by directly filling
in the struct instead of using set-up functions (the new
way) for Intel MID, Lynxpoint, Merrifield, XLP, HLWD, Aspeed,
ZX, VF610, TQMX86, MT7621, Zynq and EP93xx.
Out-of-band changes:
- Fix a GPIO header inclusion in Unicore - no response from
maintainer.
- Drop FMC subsystem from MAINTAINERS - was deleted in the
GPIO tree last cycle so let's mop up the shards.

callback in the main chip or GPIO interrupt chip respectively.
Allocate it with bitmap_alloc().
- Isolate the device tree/open firmware GPIO description code out in
its own file properly.
- Isolate the ACPI GPIO description code out in its own file
properly.
- Drop a whole lot of #ifdef:s in the main includes: it does not hurt
to keep the include items around, and we get quicker and clearer
compile failures if the appropriate kernel symbols are not selected
for drivers.
New/deleted drivers:
- New driver for Aspeed SGPIO.
- The KS8695 driver is deleted as the platform gets deleted from
arch/arm in this kernel cycle.
- The Cirrus Logic Madera driver now supports CS47L92 and CS47L15.
- The Freescale MPC8xxx now supports LS1028A and LS1088A.
Driver improvements:
- We pass the GPIO irqchip intialization by directly filling in the
struct instead of using set-up functions (the new way) for Intel
MID, Lynxpoint, Merrifield, XLP, HLWD, Aspeed, ZX, VF610, TQMX86,
MT7621, Zynq and EP93xx.
Out-of-band changes:
- Fix a GPIO header inclusion in Unicore - no response from
maintainer.
- Drop FMC subsystem from MAINTAINERS - was deleted in the GPIO tree
last cycle so let's mop up the shards"

ARM: dts: dir685: Drop spi-cpol from the display
The D-Link DIR-685 had its clock polarity set as active
low using the special SPI "spi-cpol" property.
This is not correct: the datasheet clearly states:
"Fix SCL to GND level when not in use" which is
indicative that this line is active high.
After a recent fix making the GPIO-based SPI driver
force the clock line de-asserted at the beginning of
each SPI transaction this reared its ugly head: now
de-asserted was taken to mean the line should be
driven high, but it should be driven low.
Fix this up in the DTS file and the display works again.

swiotlb-xen: simplify cache maintainance
Now that we know we always have the dma-noncoherent.h helpers available
if we are on an architecture with support for non-coherent devices,
we can just call them directly, and remove the calls to the dma-direct
routines, including the fact that we call the dma_direct_map_page
routines but ignore the value returned from it. Instead we now have
Xen wrappers for the arch_sync_dma_for_{device,cpu} helpers that call
the special Xen versions of those routines for foreign pages.
Note that the new helpers get the physical address passed in addition
to the dma address to avoid another translation for the local cache
maintainance. The pfn_valid checks remain on the dma address as in
the old code, even if that looks a little funny.

ARM: 8905/1: Emit __gnu_mcount_nc when using Clang 10.0.0 or newer
Currently, multi_v7_defconfig + CONFIG_FUNCTION_TRACER fails to build

arm-linux-gnueabi-ld: kernel/softirq.o:softirq.c:(.text+0xa50): more undefined references to `mcount' follow
clang can emit a working mcount symbol, __gnu_mcount_nc, when
'-meabi gnu' is passed to it. Until r369147 in LLVM, this was
broken and caused the kernel not to boot with '-pg' because the
calling convention was not correct. Always build with '-meabi gnu'
when using clang but ensure that '-pg' (which is added with
CONFIG_FUNCTION_TRACER and its prereq CONFIG_HAVE_FUNCTION_TRACER)
cannot be added with it unless this is fixed (which means using
clang 10.0.0 and newer).
