c89ab04feb mm/sparse: cleanup the code surrounding memory_present()
After removal of CONFIG_HAVE_MEMBLOCK_NODE_MAP we have two equivalent
functions that call memory_present() for each region in memblock.memory:
sparse_memory_present_with_active_regions() and membocks_present().

Moreover, all architectures have a call to either of these functions
preceding the call to sparse_init() and in the most cases they are called
one after the other.

Mark the regions from memblock.memory as present during sparce_init() by
making sparse_init() call memblocks_present(), make memblocks_present()
and memory_present() functions static and remove redundant
sparse_memory_present_with_active_regions() function.

Also remove no longer required HAVE_MEMORY_PRESENT configuration option.

56993b4e14 mm/sparsemem: enable vmem_altmap support in vmemmap_alloc_block_buf()
There are many instances where vmemap allocation is often switched between
regular memory and device memory just based on whether altmap is available
or not.  vmemmap_alloc_block_buf() is used in various platforms to
allocate vmemmap mappings.  Lets also enable it to handle altmap based
device memory allocation along with existing regular memory allocations.
This will help in avoiding the altmap based allocation switch in many
places.  To summarize there are two different methods to call
vmemmap_alloc_block_buf().

vmemmap_alloc_block_buf(size, node, NULL)   /* Allocate from system RAM */
vmemmap_alloc_block_buf(size, node, altmap) /* Allocate from altmap */

This converts altmap_alloc_block_buf() into a static function, drops it's
entry from the header and updates Documentation/vm/memory-model.rst.

ea3271f719 tmpfs: support 64-bit inums per-sb
The default is still set to inode32 for backwards compatibility, but
system administrators can opt in to the new 64-bit inode numbers by
either:

1. Passing inode64 on the command line when mounting, or
2. Configuring the kernel with CONFIG_TMPFS_INODE64=y

The inode64 and inode32 names are used based on existing precedent from
XFS.

060807f841 mm, slub: make remaining slub_debug related attributes read-only
SLUB_DEBUG creates several files under /sys/kernel/slab/<cache>/ that can
be read to check if the respective debugging options are enabled for given
cache.  Some options, namely sanity_checks, trace, and failslab can be
also enabled and disabled at runtime by writing into the files.

The runtime toggling is racy.  Some options disable __CMPXCHG_DOUBLE when
enabled, which means that in case of concurrent allocations, some can
still use __CMPXCHG_DOUBLE and some not, leading to potential corruption.
The s->flags field is also not updated or checked atomically.  The
simplest solution is to remove the runtime toggling.  The extended
slub_debug boot parameter syntax introduced by earlier patch should allow
to fine-tune the debugging configuration during boot with same
granularity.

ad38b5b113 mm, slub: make some slub_debug related attributes read-only
SLUB_DEBUG creates several files under /sys/kernel/slab/<cache>/ that can
be read to check if the respective debugging options are enabled for given
cache.  The options can be also toggled at runtime by writing into the
files.  Some of those, namely red_zone, poison, and store_user can be
toggled only when no objects yet exist in the cache.

Vijayanand reports [1] that there is a problem with freelist randomization
if changing the debugging option's state results in different number of
objects per page, and the random sequence cache needs thus needs to be
recomputed.

However, another problem is that the check for "no objects yet exist in
the cache" is racy, as noted by Jann [2] and fixing that would add
overhead or otherwise complicate the allocation/freeing paths.  Thus it
would be much simpler just to remove the runtime toggling support.  The
documentation describes it's "In case you forgot to enable debugging on
the kernel command line", but the neccessity of having no objects limits
its usefulness anyway for many caches.

Vijayanand describes an use case [3] where debugging is enabled for all
but zram caches for memory overhead reasons, and using the runtime toggles
was the only way to achieve such configuration.  After the previous patch
it's now possible to do that directly from the kernel boot option, so we
can remove the dangerous runtime toggles by making the /sys attribute
files read-only.

While updating it, also improve the documentation of the debugging /sys files.

e17f1dfba3 mm, slub: extend slub_debug syntax for multiple blocks
Patch series "slub_debug fixes and improvements".

The slub_debug kernel boot parameter can either apply a single set of
options to all caches or a list of caches.  There is a use case where
debugging is applied for all caches and then disabled at runtime for
specific caches, for performance and memory consumption reasons [1].  As
runtime changes are dangerous, extend the boot parameter syntax so that
multiple blocks of either global or slab-specific options can be
specified, with blocks delimited by ';'.  This will also support the use
case of [1] without runtime changes.

For details see the updated Documentation/vm/slub.rst

4510a5a98a ocfs2: replace HTTP links with HTTPS ones

Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `xmlns`:
        For each link, `http://[^# 	]*(?:\w|/)`:
	  If neither `gnu\.org/license`, nor `mozilla\.org/MPL`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

Pull drm updates from Dave Airlie:
 "New xilinx displayport driver, AMD support for two new GPUs (more
  header files), i915 initial support for RocketLake and some work on
  their DG1 (discrete chip).

  The core also grew some lockdep annotations to try and constrain what
  drivers do with dma-fences, and added some documentation on why the
  idea of indefinite fences doesn't work.

e4a7b2dc35 LEDs changes for 5.9-rc1.
Okay, so... this one is interesting. RGB LEDs are very common, and we
 need to have some kind of support for them. Multicolor is for
 arbitrary set of LEDs in one package, RGB is for LEDs that can produce
 full range of colors. We do not have real multicolor LED that is not
 RGB in the pipeline, so that one is disabled for now.
 
 You can expect this saga to continue with next pull requests.

1d8ce0e093 This is the bulk of GPIO changes for the v5.9 kernel cycle:
Core changes:
 
 - Introduce the for_each_requested_gpio() macro to help in
   dependent code all over the place. Also patch a few locations
   to use it while we are at it.
 
 - Split out the sysfs code into its own file.
 
 - Split out the character device code into its own file, then
   make a set of refactorings and improvements to this code.
   We are setting the stage to revamp the userspace API a bit

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v5.9 kernel cycle.

  There is nothing too exciting in it, but a new macro that fixes a
  build failure on a minor ARM32 platform that appeared yesterday is
  part of it so we better merge it.

  Core changes:

   - Introduce the for_each_requested_gpio() macro to help in dependent
     code all over the place. Also patch a few locations to use it while
     we are at it.

   - Split out the sysfs code into its own file.

   - Split out the character device code into its own file, then make a
     set of refactorings and improvements to this code. We are setting
     the stage to revamp the userspace API a bit in the next cycle.

   - Fix a whole slew of kerneldoc that was wrong or missing.

  New drivers:

   - The PCA953x driver now supports the PCAL9535.

  Driver improvements:

   - A host of incremental modernizations and improvements to the
     PCA953x driver.

dd27111e32 Driver core changes for 5.9-rc1
Here is the "big" set of changes to the driver core, and some drivers
 using the changes, for 5.9-rc1.
 
 "Biggest" thing in here is the device link exposure in sysfs, to help
 to tame the madness that is SoC device tree representations and driver
 interactions with it.
 
 Other stuff in here that is interesting is:
 	- device probe log helper so that drivers can report problems in
 	  a unified way easier.
 	- devres functions added
 	- DEVICE_ATTR_ADMIN_* macro added to make it harder to write
 	  incorrect sysfs file permissions
 	- documentation cleanups
 	- ability for debugfs to be present in the kernel, yet not
 	  exposed to userspace.  Needed for systems that want it
 	  enabled, but do not trust users, so they can still use some
 	  kernel functions that were otherwise disabled.
 	- other minor fixes and cleanups
 
 The patches outside of drivers/base/ all have acks from the respective
 subsystem maintainers to go through this tree instead of theirs.
 
 All of these have been in linux-next with no reported issues.

4da9f33026 Support for FSGSBASE. Almost 5 years after the first RFC to support it,
this has been brought into a shape which is maintainable and actually
 works.
 
 This final version was done by Sasha Levin who took it up after Intel
 dropped the ball. Sasha discovered that the SGX (sic!) offerings out there
 ship rogue kernel modules enabling FSGSBASE behind the kernels back which
 opens an instantanious unpriviledged root hole.
 
 The FSGSBASE instructions provide a considerable speedup of the context
 switch path and enable user space to write GSBASE without kernel
 interaction. This enablement requires careful handling of the exception
 entries which go through the paranoid entry path as they cannot longer rely
 on the assumption that user GSBASE is positive (as enforced via prctl() on
 non FSGSBASE enabled systemn). All other entries (syscalls, interrupts and
 exceptions) can still just utilize SWAPGS unconditionally when the entry
 comes from user space. Converting these entries to use FSGSBASE has no
 benefit as SWAPGS is only marginally slower than WRGSBASE and locating and
 retrieving the kernel GSBASE value is not a free operation either. The real
 benefit of RD/WRGSBASE is the avoidance of the MSR reads and writes.
 
 The changes come with appropriate selftests and have held up in field
 testing against the (sanitized) Graphene-SGX driver.

2baa85d692 ACPI updates for 5.9-rc1
- Eliminate significant AML processing overhead related to using
    operation regions in system memory by reworking the management
    of memory mappings in the ACPI code to defer unmap operations
    (to do them outside of the ACPICA locks, among other things) and
    making the memory operation reagion handler avoid releasing memory
    mappings created by it too early (Rafael Wysocki).
 
  - Update the ACPICA code in the kernel to upstream revision
    20200717:
 
    * Prevent operation region reference counts from overflowing in
      some cases (Erik Kaneda).
 
    * Replace one-element array with flexible-array (Gustavo A. R.
      Silva).
 
  - Fix ACPI PCI hotplug reference counting (Rafael Wysocki).
 
  - Drop last bits of the ACPI procfs interface (Thomas Renninger).
 
  - Drop some redundant checks from the code parsing ACPI tables
    related to NUMA (Hanjun Guo).
 
  - Avoid redundant object evaluation in the ACPI device properties
    handling code (Heikki Krogerus).
 
  - Avoid unecessary memory overhead related to storing the signatures
    of the ACPI tables recognized by the kernel (Ard Biesheuvel).
 
  - Add missing newline characters when printing module parameter

Pull ACPI updates from Rafael Wysocki:
 "These eliminate significant AML processing overhead related to using
  operation regions in system memory, update the ACPICA code in the
  kernel to upstream revision 20200717 (including a fix to prevent
  operation region reference counts from overflowing in some cases),
  remove the last bits of the (long deprecated) ACPI procfs interface
  and do some assorted cleanups.

  Specifics:

   - Eliminate significant AML processing overhead related to using
     operation regions in system memory by reworking the management of
     memory mappings in the ACPI code to defer unmap operations (to do
     them outside of the ACPICA locks, among other things) and making
     the memory operation reagion handler avoid releasing memory
     mappings created by it too early (Rafael Wysocki).

   - Update the ACPICA code in the kernel to upstream revision 20200717:

       * Prevent operation region reference counts from overflowing in
         some cases (Erik Kaneda).

       * Replace one-element array with flexible-array (Gustavo A. R.
         Silva).

   - Fix ACPI PCI hotplug reference counting (Rafael Wysocki).

   - Drop last bits of the ACPI procfs interface (Thomas Renninger).

   - Drop some redundant checks from the code parsing ACPI tables
     related to NUMA (Hanjun Guo).

   - Avoid redundant object evaluation in the ACPI device properties
     handling code (Heikki Krogerus).

   - Avoid unecessary memory overhead related to storing the signatures
     of the ACPI tables recognized by the kernel (Ard Biesheuvel).

   - Add missing newline characters when printing module parameter
     values in some places (Xiongfeng Wang).

   - Update the link to the ACPI specifications in some places (Tiezhu
     Yang).

   - Use the fallthrough pseudo-keyword in the ACPI code (Gustavo A. R.
     Silva).

   - Drop redundant variable initialization from the APEI code (Colin
     Ian King).

   - Drop uninitialized_var() from the ACPI PAD driver (Jason Yan).

   - Replace HTTP links with HTTPS ones in the ACPI code (Alexander A.

b171373902 spi: Updates for v5.9
A fairly quiet release for SPI, nothing really going on in the core
 although there's been quite a bit of driver related activity.  This pull
 request includes the addition of some shared code in drivers/memory for
 the Renesas RPC-IF which is used by a newly added SPI driver, the memory
 subsystem doesn't seem to have a fixed maintainer at the minute and this
 seemed like the most sensible way to get that hardware supported.
 
  - Quite a few cleanups and optimizations for the Altera, Qualcomm GENI,
    sun6i and lantiq drivers.
  - Several more GPIO descriptor conversions.
  - Move the Cadence QuadSPI driver from drivers/mtd to drivers/spi.
  - New support for Mediatek MT8192 and Renesas RPC-IF, R8A7742 and
    R8A774e1.

d4db4e5532 ARM: new SoC support for v5.9
There are three SoC families newly dded to the 32-bit and
 64-bit Arm architecture code in the kernel this time:
 
  - Daniel Palmer adds initial support for two chips made by MStar, a
    taiwanese SoC manufacturer that became part of Mediatek in 2012. For
    now, the added support is fairly minimal, with just two of its
    Cortex-A7 based 32-bit camera chips getting support for a limited
    set of on-chip peripherals.
 
  - Lars Povlsen from Microchip adds support for their new Sparx5
    family of ethernet switch chips using 64-bit Cortex-A53 cores.
    These are descended from earlier VSC7xxx SparX and Ocelot chips
    using 32-bit MIPS cores.
 
  - Daniele Alessandrelli from Intel adds support for the new Keem Bay
    SoC for computer vision, built around a Movidius VPU with Linux
    running on Arm Cortex-A53 cores.

Pull new ARM SoC support from Arnd Bergmann:
 "There are three SoC families newly dded to the 32-bit and 64-bit Arm
  architecture code in the kernel this time:

   - Daniel Palmer adds initial support for two chips made by MStar, a
     taiwanese SoC manufacturer that became part of Mediatek in 2012.

     For now, the added support is fairly minimal, with just two of its
     Cortex-A7 based 32-bit camera chips getting support for a limited
     set of on-chip peripherals.

   - Lars Povlsen from Microchip adds support for their new Sparx5
     family of ethernet switch chips using 64-bit Cortex-A53 cores.

     These are descended from earlier VSC7xxx SparX and Ocelot chips
     using 32-bit MIPS cores.

   - Daniele Alessandrelli from Intel adds support for the new Keem Bay
     SoC for computer vision, built around a Movidius VPU with Linux
     running on Arm Cortex-A53 cores"

822ef14e9d ARM: SoC driver updates for v5.9
A couple of subsystems have their own subsystem maintainers but choose
 to have the code merged through the soc tree as upstream, as the code
 tends to be used across multiple SoCs or has SoC specific drivers itself:
 
  - memory controllers:
      Krzysztof Kozlowski takes ownership of the drivers/memory
      subsystem and its drivers, starting out with a set of cleanup
      patches.
      A larger driver for the Tegra memory controller that was accidentally
      missed for v5.8 is now added.
 
  - reset controllers:
      Only minor updates to drivers/reset this time
 
  - firmware:
      The "turris mox" firmware driver gains support for signed firmware blobs
      The tegra firmware driver gets extended to export some debug information
      Various updates to i.MX firmware drivers, mostly cosmetic
 
  - ARM SCMI/SCPI:
      A new mechanism for platform notifications is added, among a number
      of minor changes.
 
  - optee:
      Probing of the TEE bus is rewritten to better support detection of
      devices that depend on the tee-supplicant user space.
      A new firmware based trusted platform module (fTPM) driver is added
      based on OP-TEE
 
  - SoC attributes:
      A new driver is added to provide a generic soc_device for identifying
      a machine through the SMCCC ARCH_SOC_ID firmware interface rather than
      by probing SoC family specific registers.
      The series also contains some cleanups to the common soc_device code.
 
 There are also a number of updates to SoC specific drivers,
 the main ones are:
 
  - Mediatek cmdq driver gains a few in-kernel interfaces
 
  - Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding
    support for additional SoC variants
 
  - The Qualcomm GENI core code gains interconnect path voting and
    performance level support, and integrating this into a number of
    device drivers.
 
  - A new driver for Samsung Exynos5800 voltage coupler for
 
  - Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC
    specific device drivers
 
  - Updates to the TI K3 Ring Accelerator driver

2f3fbfdaf7 ARM: SoC DT changes for 5.9
As usual, there are many patches addressing minor issues in existing
 DTS files, such as DTC warnings, or adding support for additional
 peripherals.
 
 There are three added SoCs in existing product families:
 
  - Amazon:
     Alpine v3 is a 16-core Cortex-A72 SoC from Amazon's Annapurna Labs,
     otherwise known as AL73400 or first-generation Graviton, and following
     the already supported Cortex-A1`5 and Cortex-A57 based Alpine chips.
     This one is added together with the official Evaluation platform.
 
  - Qualcomm:
     The Snapdragon SDM630 platform is a family of mid-range mobile phone
     chips from 2017 based on Cortex-A53 or Kryo 260 CPUs.
     A total of five end-user products are added based on these, all
     Android phones from Sony: Xperia 10, 10 Plus, XA2, XA2 Plus and
     XA2 Ultra.
 
  - Renesas:
     RZ/G2H (r8a774e1) is currently the top model in the Renesas RZ/G
     family, and apparently closely related to the RZ/G2N and RZ/G2M
     models we already support but has a faster GPU and additional
     on-chip peripherals.
     It is added along with the HopeRun HiHope RZ/G2H development board
 
 A small number of new boards for already supported SoCs also debut:
 
  - Allwinner sunxi:
     Only one new machine, revision v1.2 of the Pine64 PinePhone
     (non-Android) smartphone, containing minor changes compared to
     earlier versions.
 
  - Amlogic Meson:
     WeTek Core2 is an Amlogic S912 (GXM) based Set-top-box
 
  - Aspeed:
     EthanolX is AMD's EPYC data center rerence platform, using an
     ASpeed AST2600 baseboard management controller.

     based on the MT8183 (Helio P60t) SoC.
 
  - Nvidia Tegra:
     ASUS Google Nexus 7 and Acer Iconia Tab A500 are two Android
     tablets from around 2012 using Tegra 3 and Tegra 2, respectively.
     Thanks to PostmarketOS, these can now run mainline kernels
     and become useful again.
 
     The Jetson Xavier NX Developer Kit uses a SoM and carrier board
     for the Tegra194, their latest 64-bit chip based on Carmel CPU
     cores and Volta graphics.
 
  - NXP i.MX:
     Five new boards based on the 32-bit i.MX6 series are added:
     The MYiR MYS-6ULX single-board computer, and four different
     models of industrial computers from Protonic.
 
  - Qualcomm:
     MikroTik RouterBoard 3011 is a rackmounted router based on the
     32-bit IPQ8064 networking SoC
     Three older phones get added, the Snapdragon 808 (msm8992) based
     Xiaomi Libra (Mi 4C) and Microsoft Lumia 950, originally running
     Windows Phone, and the Snapdragon 810 (msm8994) based Sony
     Xperia Z5.
 
  - Renesas:
     In addition to the HiHope RZ/G2H board mentioned above, we gain
     support for board versions 3.0 and 4.0 of the earlier RZ/G2M and
     RZ/G2N reference boards.
     Beacon EmbeddedWorks adds another SoM+Carrier development board
     for RZ/G2M.
 
  - Rockchips:
     Radxa Rock Pi N8 development board and the VMARC RK3288 SoM it
     is based on, using the high-end 32-bit rk3288 SoC.
 
 Notable updates to existing platforms are usually for added on-chip
 peripherals, including:
 
  - ASpeed AST2xxx (various)
 
  - Allwinner (cpufreq, thermal, Pinephone touchscreen)
 
  - Amlogic Meson (audio, gpu dvdfs, board updates)
 
  - Arm Versatile
 
  - Broadcom (board updates for switch ports, Raspberry pi clock updates)
 
  - Hisilicon (various)
 
  - Intel/Altera SoCFPGA (various)
 
  - Marvell Armada 7xxx/8xxx (smmu)
 
  - Marvell MMP (GPU on mmp2/mmp3)
 
  - Mediatek mt8183 (USB, pericfg)
 
  - NXP Layerscape (VPU, thermal, DSPI)
 
  - NXP i.MX (VPU, bindings, board updates)
 
  - Nvidia Tegra194 (GPU)
 
  - Qualcomm (GPU, Interconnect, ...)
 
  - Renesas R-Car (SPI, IPMMU, board updates)

76769c38b4 mlx5-updates-2020-08-03
This patchset introduces some updates to mlx5 driver.
 
 1) Jakub converts mlx5 to use the new udp tunnel infrastructure.
    Starting with a hack to allow drivers to request a static configuration
    of the default vxlan port, and then a patch that converts mlx5.
 
 2) Parav implements change_carrier ndo for VF eswitch representors,
    to speedup link state control of representors netdevices.
 
 3) Alex Vesker, makes a simple update to software steering to fix an issue
    with push vlan action sequence
 
 4) Leon removes a redundant dump stack on error flow.

c0dfadfed8 The main change in this cycle was to add support for ZSTD-compressed
kernel and initrd images.
 
 ZSTD has a very fast decompressor, yet it compresses better than gzip.

c44a1b9175 dt-bindings: net: mdio: add reset-post-delay-us property
Add "reset-post-delay-us" parameter to MDIO bus properties,
so it's possible to add a delay after reset deassert.
This is optional in case external hardware slows down
release of the reset signal.
