Bastien Nocera 015664d152 USB: rio500: Remove Rio 500 kernel driver
The Rio500 kernel driver has not been used by Rio500 owners since 2001
not long after the rio500 project added support for a user-space USB stack
through the very first versions of usbdevfs and then libusb.

Support for the kernel driver was removed from the upstream utilities
in 2008:

Mark Rutland b4ed71f557 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.

Alexandre Ghiti dba79c3df4 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.

Mike Rapoport 782de70c42 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().

Nicholas Piggin 13224794cb 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.

Linus Torvalds f97c81dc6c 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.

Arnd Bergmann b74d957f63 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.

Linus Torvalds c6b48dad92 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.

Linus Torvalds 6ab8ad3160 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

Linus Torvalds cef7298262 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.

     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"

Linus Torvalds 399eb9b6cb 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.

Linus Torvalds 2b97c39514 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.

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

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
     syscalls

   - Early RNG seeding by the bootloader

   - Improve robustness of SMP boot

   - Fix TLB invalidation in light of recent architectural
     clarifications

   - Support for i.MX8 DDR PMU

   - Remove direct LSE instruction patching in favour of static keys

   - Function error injection using kprobes

Linus Torvalds bbfe0d6b8b 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.

Linus Walleij 2a7326caab 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.

Christoph Hellwig b4dca15129 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.

Nathan Chancellor b0fe66cf09 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
with clang:

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).
