Rob Herring ad21a4ce04 dt-bindings: pinctrl: aspeed: Fix 'compatible' schema errors
The Aspeed pinctl schema have errors in the 'compatible' schema:

Documentation/devicetree/bindings/pinctrl/aspeed,ast2400-pinctrl.yaml: \
properties:compatible:enum: ['aspeed', 'ast2400-pinctrl', 'aspeed', 'g4-pinctrl'] has non-unique elements
Documentation/devicetree/bindings/pinctrl/aspeed,ast2500-pinctrl.yaml: \
properties:compatible:enum: ['aspeed', 'ast2500-pinctrl', 'aspeed', 'g5-pinctrl'] has non-unique elements

Flow style sequences have to be quoted if the vales contain ','. Fix
this by using the more common one line per entry formatting.

Rob Herring 7d9ef7f37d dt-bindings: riscv: Limit cpus schema to only check RiscV 'cpu' nodes
Matching on the 'cpus' node was a bad choice because the schema is
incorrectly applied to non-RiscV cpus nodes. As we now have a common cpus
schema which checks the general structure, it is also redundant to do so
in the Risc-V CPU schema.

The downside is one could conceivably mix different architecture's cpu
nodes or have typos in the compatible string. The latter problem pretty
much exists for every schema.

Rob Herring 15ffef1ae6 dt-bindings: Ensure child nodes are of type 'object'
Properties which are child node definitions need to have an explict
type. Otherwise, a matching (DT) property can silently match when an
error is desired. Fix this up tree-wide. Once this is fixed, the
meta-schema will enforce this on any child node definitions.

Linus Torvalds af6af87d7e ARM: Device-tree updates
We continue to see a lot of new material. I've highlighted some of it
 below, but there's been more beyond that as well.
 
 One of the sweeping changes is that many boards have seen their ARM Mali
 GPU devices added to device trees, since the DRM drivers have now been
 merged.
 
 So, with the caveat that I have surely missed several great
 contributions, here's a collection of the material this time around:
 
 New SoCs:
 
  - Mediatek mt8183 (4x Cortex-A73 + 4x Cortex-A53)
 
  - TI J721E (2x Cortex-A72 + 3x Cortex-R5F + 3 DSPs + MMA)
 
  - Amlogic G12B (4x Cortex-A73 + 2x Cortex-A53)
 
 New Boards / platforms:
 
  - Aspeed BMC support for a number of new server platforms
 
  - Kontron SMARC SoM (several i.MX6 versions)
 
  - Novtech's Meerkat96 (i.MX7)
 
  - ST Micro Avenger96 board
 
  - Hardkernel ODROID-N2 (Amlogic G12B)
 
  - Purism Librem5 devkit (i.MX8MQ)
 
  - Google Cheza (Qualcomm SDM845)
 
  - Qualcomm Dragonboard 845c (Qualcomm SDM845)
 
  - Hugsun X99 TV Box (Rockchip RK3399)
 
  - Khadas Edge/Edge-V/Captain (Rockchip RK3399)
 
 Updated / expanded boards and platforms:
 
  - Renesas r7s9210 has a lot of new peripherals added
 
  - Polish and fixes for Rockchip-based Chromebooks
 
  - Amlogic G12A has a lot of peripherals added
 
  - Nvidia Jetson Nano sees various fixes and improvements, and is now at
    feature parity with TX1

  Summary of the more significant patches:

   - Patch series "mm/memory_hotplug: Factor out memory block
     devicehandling", v3. David Hildenbrand.

     Some spring-cleaning of the memory hotplug code, notably in
     drivers/base/memory.c

   - "mm: thp: fix false negative of shmem vma's THP eligibility". Yang
     Shi.

     Fix /proc/pid/smaps output for THP pages used in shmem.

   - "resource: fix locking in find_next_iomem_res()" + 1. Nadav Amit.

     Bugfix and speedup for kernel/resource.c

   - Patch series "mm: Further memory block device cleanups", David
     Hildenbrand.

     More spring-cleaning of the memory hotplug code.

   - Patch series "mm: Sub-section memory hotplug support". Dan
     Williams.

     Generalise the memory hotplug code so that pmem can use it more
     completely. Then remove the hacks from the libnvdimm code which
     were there to work around the memory-hotplug code's constraints.

   - "proc/sysctl: add shared variables for range check", Matteo Croce.

     We have about 250 instances of

          int zero;
          ...
                  .extra1 = &zero,

     in the tree. This is a tree-wide sweep to make all those private
     "zero"s and "one"s use global variables.

     Alas, it isn't practical to make those two global integers const"

Yang Shi c06306696f mm: thp: fix false negative of shmem vma's THP eligibility
Commit 7635d9cbe8 ("mm, thp, proc: report THP eligibility for each
vma") introduced THPeligible bit for processes' smaps.  But, when
checking the eligibility for shmem vma, __transparent_hugepage_enabled()
is called to override the result from shmem_huge_enabled().  It may
result in the anonymous vma's THP flag override shmem's.  For example,
running a simple test which create THP for shmem, but with anonymous THP
disabled, when reading the process's smaps, it may show:

  7fc92ec00000-7fc92f000000 rw-s 00000000 00:14 27764 /dev/shm/test
  Size:               4096 kB
  ...
  [snip]
  ...
  ShmemPmdMapped:     4096 kB
  ...
  [snip]
  ...
  THPeligible:    0

And, /proc/meminfo does show THP allocated and PMD mapped too:

  ShmemHugePages:     4096 kB
  ShmemPmdMapped:     4096 kB

This doesn't make too much sense.  The shmem objects should be treated
separately from anonymous THP.  Calling shmem_huge_enabled() with
checking MMF_DISABLE_THP sounds good enough.  And, we could skip stack
and dax vma check since we already checked if the vma is shmem already.

Also check if vma is suitable for THP by calling
transhuge_vma_suitable().

And minor fix to smaps output format and documentation.

Masahiro Yamada b7dca6dd1e kbuild: create *.mod with full directory path and remove MODVERDIR
While descending directories, Kbuild produces objects for modules,
but do not link final *.ko files; it is done in the modpost.

To keep track of modules, Kbuild creates a *.mod file in $(MODVERDIR)
for every module it is building. Some post-processing steps read the
necessary information from *.mod files. This avoids descending into
directories again. This mechanism was introduced in 2003 or so.

Later, commit 551559e13a ("kbuild: implement modules.order") added
modules.order. So, we can simply read it out to know all the modules
with directory paths. This is easier than parsing the first line of
*.mod files.

$(MODVERDIR) has a flat directory structure, that is, *.mod files
are named only with base names. This is based on the assumption that
the module name is unique across the tree. This assumption is really
fragile.

Stephen Rothwell reported a race condition caused by a module name
conflict:

  https://lkml.org/lkml/2019/5/13/991

In parallel building, two different threads could write to the same
$(MODVERDIR)/*.mod simultaneously.

Non-unique module names are the source of all kind of troubles, hence
commit 3a48a91901 ("kbuild: check uniqueness of module names")
introduced a new checker script.

However, it is still fragile in the build system point of view because
this race happens before scripts/modules-check.sh is invoked. If it
happens again, the modpost will emit unclear error messages.

To fix this issue completely, create *.mod with full directory path
so that two threads never attempt to write to the same file.

$(MODVERDIR) is no longer needed.

Since modules with directory paths are listed in modules.order, Kbuild
is still able to find *.mod files without additional descending.

I also killed cmd_secanalysis; scripts/mod/sumversion.c computes MD4 hash
for modules with MODULE_VERSION(). When CONFIG_DEBUG_SECTION_MISMATCH=y,
it occurs not only in the modpost stage, but also during directory
descending, where sumversion.c may parse stale *.mod files. It would emit
'No such file or directory' warning when an object consisting a module is
renamed, or when a single-obj module is turned into a multi-obj module or
vice versa.

Linus Torvalds 916f562fb2 This round of clk driver and framework updates is heavy on the driver update
side. The two main highlights in the core framework are the addition of an bulk
 clk_get API that handles optional clks and an extra debugfs file that tells the
 developer about the current parent of a clk.
 
 The driver updates are dominated by i.MX in the diffstat, but that is mostly
 because that SoC has started converting to the clk_hw style of clk
 registration. The next big update is in the Amlogic meson clk driver that
 gained some support for audio, cpu, and temperature clks while fixing some PLL
 issues. Finally, the biggest thing that stands out is the conversion of a large
 part of the Allwinner sunxi-ng driver to the new clk parent scheme that uses
 less strings and more pointer comparisons to match clk parents and children up.
 
 In general, it looks like we have a lot of little fixes and tweaks here and
 there to clk data along with the normal addition of a handful of new drivers
 and a couple new core framework features.
 
 Core:
  - Add a 'clk_parent' file in clk debugfs
  - Add a clk_bulk_get_optional() API (with devm too)
 
 New Drivers:
  - Support gated clk controller on MIPS based BCM63XX SoCs
  - Support SiLabs Si5341 and Si5340 chips
  - Support for CPU clks on Raspberry Pi devices
  - Audsys clock driver for MediaTek MT8516 SoCs
 
 Updates:
  - Convert a large portion of the Allwinner sunxi-ng driver to new clk parent scheme
  - Small frequency support for SiLabs Si544 chips
  - Slow clk support for AT91 SAM9X60 SoCs
  - Remove dead code in various clk drivers (-Wunused)
  - Support for Marvell 98DX1135 SoCs
  - Get duty cycle of generic pwm clks
  - Improvement in mmc phase calculation and cleanup of some rate defintions
  - Switch i.MX6 and i.MX7 clock drivers to clk_hw based APIs
  - Add GPIO, SNVS and GIC clocks for i.MX8 drivers
  - Mark imx6sx/ul/ull/sll MMDC_P1_IPG and imx8mm DRAM_APB as critical clock
  - Correct imx7ulp nic1_bus_clk and imx8mm audio_pll2_clk clock setting
  - Add clks for new Exynos5422 Dynamic Memory Controller driver
  - Clock definition for Exynos4412 Mali
  - Add CMM (Color Management Module) clocks on Renesas R-Car H3, M3-N, E3, and D3
  - Add TPU (Timer Pulse Unit / PWM) clocks on Renesas RZ/G2M
  - Support for 32 bit clock IDs in TI's sci-clks for J721e SoCs
  - TI clock probing done from DT by default instead of firmware
  - Fix Amlogic Meson mpll fractional part and spread sprectrum issues
  - Add Amlogic meson8 audio clocks
  - Add Amlogic g12a temperature sensors clocks
  - Add Amlogic g12a and g12b cpu clocks
  - Add TPU (Timer Pulse Unit / PWM) clocks on Renesas R-Car H3, M3-W, and M3-N
  - Add CMM (Color Management Module) clocks on Renesas R-Car M3-W
  - Add Clock Domain support on Renesas RZ/N1

Daniel Drake 9af93db9e1 platform/x86: asus: Rename "fan mode" to "fan boost mode"
The Asus WMI spec indicates that the function being controlled here
is called "Fan Boost Mode". The user-facing documentation also calls it
this.

The spec uses the term "fan mode" is used to refer to other things,
including functionality expected to appear on future products.
We missed this before as we are not dealing with the most readable of
specs, and didn't forsee any confusion around shortening the name.

Rename "fan mode" to "fan boost mode" to improve consistency with the
spec and to avoid a future naming conflict.

There is no interface breakage here since this has yet to be included
in an official kernel release. I also updated the kernel version listed
under ABI accordingly.

Masahiro Yamada 5ef872636c kbuild: get rid of misleading $(AS) from documents
The assembler files in the kernel are *.S instead of *.s, so they must
be preprocessed. Since 'as' of GNU binutils is not able to preprocess,
we always use $(CC) as an assembler driver.

$(AS) is almost unused in Kbuild. As of v5.2, there is just one place
that directly invokes $(AS).

  $ git grep -e '$(AS)' -e '${AS}' -e '$AS' -e '$(AS:' -e '${AS:' -- :^Documentation
  drivers/net/wan/Makefile:  AS68K = $(AS)

The documentation about *_AFLAGS* sounds like the flags were passed
to $(AS). This is somewhat misleading.

Right now, for every directory that we need to have LaTeX output,

That causes an extra overhead and it is actually a hack, as
the latex_documents line there are usually a copy of the ones
that are there already at the main conf.py.

Mauro Carvalho Chehab 08a69058c0 docs: power: add it to to the main documentation index
The power docs are orphaned at the documentation body.

While it could likely be moved to be inside some guide, I'm opting to just
adding it to the main index.rst, removing the :orphan: and adding the SPDX
header.

The reason is similar to what it was done for other driver-specific
subsystems: the docs there contain a mix of Kernelspace, uAPI and
admin-guide. So, better to keep them on its own directory,
while the docs there are not properly classified.

Mauro Carvalho Chehab 4d2e26a38f docs: powerpc: convert docs to ReST and rename to *.rst
Convert docs to ReST and add them to the arch-specific
book.

The conversion here was trivial, as almost every file there
was already using an elegant format close to ReST standard.

The changes were mostly to mark literal blocks and add a few
missing section title identifiers.

One note with regards to "--": on Sphinx, this can't be used
to identify a list, as it will format it badly. This can be
used, however, to identify a long hyphen - and "---" is an
even longer one.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

Zhenzhong Duan 3097834637 x86: Add "nopv" parameter to disable PV extensions
In virtualization environment, PV extensions (drivers, interrupts,
timers, etc) are enabled in the majority of use cases which is the
best option.

However, in some cases (kexec not fully working, benchmarking)
we want to disable PV extensions. We have "xen_nopv" for that purpose
but only for XEN. For a consistent admin experience a common command
line parameter "nopv" set across all PV guest implementations is a
better choice.

There are guest types which just won't work without PV extensions,
like Xen PV, Xen PVH and jailhouse. add a "ignore_nopv" member to
struct hypervisor_x86 set to true for those guest types and call
the detect functions only if nopv is false or ignore_nopv is true.

The Xen tmem (transcendent memory) driver can be removed, as the

state and will be removed in future Xen versions (>= 4.13).

The xen-selfballoon driver depends on tmem, so it can be removed, too.

Arnd Bergmann 6ced9aa7b5 coda: stop using 'struct timespec' in user API
We exchange file timestamps with user space using psdev device
read/write operations with a fixed but architecture specific binary
layout.

On 32-bit systems, this uses a 'timespec' structure that is defined by
the C library to contain two 32-bit values for seconds and nanoseconds.
As we get ready for the year 2038 overflow of the 32-bit signed seconds,
the kernel now uses 64-bit timestamps internally, and user space will do
the same change by changing the 'timespec' definition in the future.

Unfortunately, this breaks the layout of the coda_vattr structure, so we
need to redefine that in terms of something that does not change.  I'm
introducing a new 'struct vtimespec' structure here that keeps the
existing layout, and the same change has to be done in the coda user
space copy of linux/coda.h before anyone can use that on a 32-bit
architecture with 64-bit time_t.

An open question is what should happen to actual times past y2038, as
they are now truncated to the last valid date when sent to user space,
and interpreted as pre-1970 times when a timestamp with the MSB set is
read back into the kernel.  Alternatively, we could change the new
timespec64_to_coda()/coda_to_timespec64() functions to use a different
interpretation and extend the available range further to the future by
disallowing past timestamps.  This would require more changes in the
user space side though.

Kairui Song c6c405336b vmcore: add a kernel parameter novmcoredd
Since commit 2724273e8f ("vmcore: add API to collect hardware dump in
second kernel"), drivers are allowed to add device related dump data to
vmcore as they want by using the device dump API.  This has a potential
issue, the data is stored in memory, drivers may append too much data
and use too much memory.  The vmcore is typically used in a kdump kernel
which runs in a pre-reserved small chunk of memory.  So as a result it
will make kdump unusable at all due to OOM issues.

So introduce new 'novmcoredd' command line option.  User can disable
device dump to reduce memory usage.  This is helpful if device dump is
using too much memory, disabling device dump could make sure a regular
vmcore without device dump data is still available.

Mauro Carvalho Chehab 113094f743 docs: add some directories to the main documentation index
The contents of those directories were orphaned at the documentation
body.

While those directories could likely be moved to be inside some guide,
I'm opting to just adding their indexes to the main one, removing the
:orphan: and adding the SPDX header.

For the drivers, the rationale is that the documentation contains
a mix of Kernelspace, uAPI and admin-guide. So, better to keep them on
separate directories, as we've be doing with similar subsystem-specific
docs that were not split yet.

For the others, well... I'm too lazy to do the move. Also, it
seems to make sense to keep at least some of those at the main
dir (like kbuild, for example). In any case, a latter patch
could do the move.

Rename the iio documentation files to ReST, add an
index for them and adjust in order to produce a nice html

The cdrom.txt and hdio.txt have their own particular syntax.
In order to speedup the conversion, I used a small ancillary
perl script:

	my $d;
	$d .= $_ while(<>);
	$d =~ s/(\nCDROM\S+)\s+(\w[^\n]*)/$1\n\t$2\n/g;
	$d =~ s/(\nHDIO\S+)\s+(\w[^\n]*)/$1\n\t$2\n/g;
	$d =~ s/(\n\s*usage:)[\s\n]*(\w[^\n]*)/$1:\n\n\t  $2\n/g;
	$d =~ s/(\n\s*)(E\w+[\s\n]*\w[^\n]*)/$1- $2/g;
	$d =~ s/(\n\s*)(inputs|outputs|notes):\s*(\w[^\n]*)/$1$2:\n\t\t$3\n/g;
	print $d;

It basically add blank lines on a few interesting places. The
script is not perfect: still several things require manual work,
but it saved quite some time doing some obvious stuff.

Mauro Carvalho Chehab 08536105d9 docs: ioctl-number.txt: convert it to ReST format
The conversion itself is simple: add a markup for the
title of this file and add markups for both tables.

Yet, the big table here with IOCTL numbers is badly formatted:
on several lines, the "Include File" column has some values that
are bigger than the reserved space there.

Also, on several places, a comment was misplaced at the "Include
File" space.

So, most of the work here is to actually ensure that each field
will be properly fixed.

Also worth to mention that some URLs have the asterisk character
on it. Well, Sphinx has an issue with asterisks in the middle
of an string. As this is URL, use the alternate format: %2A.

As a side effect of this patch, it is now a lot easier to see that
some reserved ioctl numbers are missing the include files
where it is supposed to be used.

PS.: While this is part of a subdir, I opted to convert this
single file alone, as this file has a potential of conflicts,
as most subsystem maintainers touch it.

Linus Torvalds fec88ab0af HMM patches for 5.3
Improvements and bug fixes for the hmm interface in the kernel:
 
 - Improve clarity, locking and APIs related to the 'hmm mirror' feature
   merged last cycle. In linux-next we now see AMDGPU and nouveau to be
   using this API.
 
 - Remove old or transitional hmm APIs. These are hold overs from the past
   with no users, or APIs that existed only to manage cross tree conflicts.
   There are still a few more of these cleanups that didn't make the merge
   window cut off.
 
 - Improve some core mm APIs:
   * export alloc_pages_vma() for driver use
   * refactor into devm_request_free_mem_region() to manage
     DEVICE_PRIVATE resource reservations
   * refactor duplicative driver code into the core dev_pagemap
     struct
 
 - Remove hmm wrappers of improved core mm APIs, instead have drivers use
   the simplified API directly
 
 - Remove DEVICE_PUBLIC
 
 - Simplify the kconfig flow for the hmm users and core code

Linus Torvalds 5516745311 platform-drivers-x86 for v5.3-1
ASUS WMI driver got a big refactoring in order to support the TUF Gaming
 laptops. Besides that, the regression with backlight being permanently off
 on various EeePC laptops has been fixed.
 
 Accelerometer on HP ProBook 450 G0 shows wrong measurements due to
 X axis being inverted. This has been fixed.
 
 Intel PMC core driver has been extended to be ACPI enumerated
 if the DSDT provides device with _HID "INT33A1". This allows
 to convert the driver to be pure platform and support new hardware
 purely based on ACPI DSDT.
 
 From now on the Intel Speed Select Technology is supported thru
 a corresponding driver. This driver provides an access to the features
 of the ISST, such as Performance Profile, Core Power, Base frequency and
 Turbo Frequency.
 
 Mellanox platform drivers has been refactored and now extended
 to support more systems, including new coming ones.
 
 The OLPC XO-1.75 platform is now supported.
 
 CB4063 Beckhoff Automation board is using PMC clocks,
 provided via pmc_atom driver, for ethernet controllers in a way
 that they can't be managed by the clock driver. The quirk
 has been extended to cover this case.
 
 Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile
 the information of Chuwi Hi10 Air has been fixed to cover more models
 based on the same platform.
 
 Xiaomi notebooks have WMI interface enabled. Thus, the driver to support it
 has been provided. It required some extension of the generic WMI library,
 which allows to propagate opaque context to the ->probe() of the
 individual drivers.
 
 This release includes debugfs clean up from Greg KH for several drivers
 that drop return code check and make debugfs absence or failure non-fatal.
 
 Miscellaneous fixes here and there, mostly for Acer WMI and
 various Intel drivers.
 
 The listed below commits are duplicated due to previously pushed fixes in v5.2 cycle:
 - 1dd93f873d platform/x86: asus-wmi: Only Tell EC the OS will handle display hotkeys from asus_nb_wmi

Linus Torvalds 192f0f8e9d powerpc updates for 5.3
Notable changes:
 
  - Removal of the NPU DMA code, used by the out-of-tree Nvidia driver, as well
    as some other functions only used by drivers that haven't (yet?) made it
    upstream.
 
  - A fix for a bug in our handling of hardware watchpoints (eg. perf record -e
    mem: ...) which could lead to register corruption and kernel crashes.
 
  - Enable HAVE_ARCH_HUGE_VMAP, which allows us to use large pages for vmalloc
    when using the Radix MMU.
 
  - A large but incremental rewrite of our exception handling code to use gas
    macros rather than multiple levels of nested CPP macros.
 
 And the usual small fixes, cleanups and improvements.
