Chenyi Qiang ed2351174e KVM: x86: Extend KVM_{G,S}ET_VCPU_EVENTS to support pending triple fault
For the triple fault sythesized by KVM, e.g. the RSM path or
nested_vmx_abort(), if KVM exits to userspace before the request is
serviced, userspace could migrate the VM and lose the triple fault.

Extend KVM_{G,S}ET_VCPU_EVENTS to support pending triple fault with a
new event KVM_VCPUEVENT_VALID_FAULT_FAULT so that userspace can save and
restore the triple fault event. This extension is guarded by a new KVM
capability KVM_CAP_TRIPLE_FAULT_EVENT.

Note that in the set_vcpu_events path, userspace is able to set/clear
the triple fault request through triple_fault.pending field.

Zeng Guang 3587531638 KVM: x86: Allow userspace to set maximum VCPU id for VM
Introduce new max_vcpu_ids in KVM for x86 architecture. Userspace
can assign maximum possible vcpu id for current VM session using
KVM_CAP_MAX_VCPU_ID of KVM_ENABLE_CAP ioctl().

This is done for x86 only because the sole use case is to guide
memory allocation for PID-pointer table, a structure needed to
enable VMX IPI.

By default, max_vcpu_ids set as KVM_MAX_VCPU_IDS.

Linus Torvalds c6f2f3e2c8 Add partial Loongarch architecture code
This is the majority of the loongarch architecture code, including
 the final system call interface and all core functionality.
 
 It still misses three sets of peripheral but vital patches to add
 support for other subsystems, which have yet to pass review:
 
  - The drivers/firmware/efi stub for booting from a standard UEFI
    firmware implementation. Both the original custom boot interface
    and a draft implementation of the EFI stub did not make it, so
    it is currently impossible to boot the kernel, until the
    loongarch specific portions get accepted into the UEFI subsystem
 
  - The drivers/irqchip/irq-loongson-*.c drivers are shared with the
    the MIPS port, but currently lack support for ACPI based booting,
    which will get merged through the irqchip subsystem.
 
  - Similarly, the drivers/pci/controller/pci-loongson.c needs to be
    modified for ACPI support, which will be merged through the
    PCI subsystem.
 
 While the port cannot actually be used before all the above are
 merged, having it in 5.19 helps to establish the user space ABI
 for the libc ports to build on, and to help any treewide changes
 in the mainline kernel get applied here as well. A gcc-12 based
 tool chains for build testing is now included in

Linus Torvalds f66e797b40 RISC-V Patches for the 5.19 Merge Window, Part 2
This is mostly some DT updates, but also a handful of cleanups and some
 fixes.  The most user-visible of those are:
 
 * A device tree for the Sundance Polarberry, along with a handful of
   fixes and clenups to the PolarFire SOC device trees and bindings.
 * The memfd_secret syscall number is now visible to userspace,
 * Some improvements to the vm layout dump, which really should have
   followed shortly after the sv48 patches but I missed.

Linus Torvalds 500a434fc5 Driver core changes for 5.19-rc1
Here is the set of driver core changes for 5.19-rc1.
 
 Note, I'm not really happy with this pull request as-is, see below for
 details, but overall this is all good for everything but a small set of
 systems, which we have a fix for already.
 
 Lots of tiny driver core changes and cleanups happened this cycle,
 but the two major things were:
 
 	- firmware_loader reorganization and additions including the
 	  ability to have XZ compressed firmware images and the ability
 	  for userspace to initiate the firmware load when it needs to,
 	  instead of being always initiated by the kernel. FPGA devices
 	  specifically want this ability to have their firmware changed
 	  over the lifetime of the system boot, and this allows them to
 	  work without having to come up with yet-another-custom-uapi
 	  interface for loading firmware for them.
 	- physical location support added to sysfs so that devices that
 	  know this information, can tell userspace where they are
 	  located in a common way.  Some ACPI devices already support
 	  this today, and more bus types should support this in the
 	  future.
 
 Smaller changes included:
 	- driver_override api cleanups and fixes
 	- error path cleanups and fixes
 	- get_abi script fixes
 	- deferred probe timeout changes.
 
 It's that last change that I'm the most worried about.  It has been
 reported to cause boot problems for a number of systems, and I have a
 tested patch series that resolves this issue.  But I didn't get it
 merged into my tree before 5.18-final came out, so it has not gotten any
 linux-next testing.
 
 I'll send the fixup patches (there are 2) as a follow-on series to this
 pull request if you want to take them directly, _OR_ I can just revert
 the probe timeout changes and they can wait for the next -rc1 merge
 cycle.  Given that the fixes are tested, and pretty simple, I'm leaning
 toward that choice.  Sorry this all came at the end of the merge window,
 I should have resolved this all 2 weeks ago, that's my fault as it was
 in the middle of some travel for me.
 
 All have been tested in linux-next for weeks, with no reported issues
 other than the above-mentioned boot time outs.

Linus Torvalds 6f9b5ed8ca Char / Misc / Other smaller driver subsystem updates for 5.19-rc1
Here is the large set of char, misc, and other driver subsystem updates
 for 5.19-rc1.  The merge request for this has been delayed as I wanted
 to get lots of linux-next testing due to some late arrivals of changes
 for the habannalabs driver.
 
 Highlights of this merge are:
 	- habanalabs driver updates for new hardware types and fixes and
 	  other updates
 	- IIO driver tree merge which includes loads of new IIO drivers
 	  and cleanups and additions
 	- PHY driver tree merge with new drivers and small updates to
 	  existing ones
 	- interconnect driver tree merge with fixes and updates
 	- soundwire driver tree merge with some small fixes
 	- coresight driver tree merge with small fixes and updates
 	- mhi bus driver tree merge with lots of updates and new device
 	  support
 	- firmware driver updates
 	- fpga driver updates
 	- lkdtm driver updates (with a merge conflict, more on that
 	  below)
 	- extcon driver tree merge with small updates
 	- lots of other tiny driver updates and fixes and cleanups, full
 	  details in the shortlog.
 
 All of these have been in linux-next for almost 2 weeks with no reported
 problems.
 
 Note, there are 3 merge conflicts when merging this with your tree:
 	- MAINTAINERS, should be easy to resolve
 	- drivers/slimbus/qcom-ctrl.c, should be straightforward
 	  resolution
 	- drivers/misc/lkdtm/stackleak.c, not an easy resolution.  This
 	  has been noted in the linux-next tree for a while, and
 	  resolved there, here's a link to the resolution that Stephen
 	  came up with and that Kees says is correct:
 	  	https://lore.kernel.org/r/20220509185344.3fe1a354@canb.auug.org.au
 
 I will be glad to provide a merge point that contains these resolutions
 if that makes things any easier for you.

Here is the "big" set of USB and Thunderbolt driver changes for

 	- Thunderbolt driver updates:
 		- fixes for devices without displayport adapters
 		- lane bonding support and improvements
 		- other minor changes based on device testing
 	- dwc3 gadget driver changes.  It seems this driver will never
 	  be finished given that the IP core is showing up in zillions
 	  of new devices and each implementation decides to do something
 	  different with it...
 	- uvc gadget driver updates as more devices start to use and
 	  rely on this hardware as well
 	- usb_maxpacket() api changes to remove an unneeded and unused
 	  parameter.
 	- usb-serial driver device id updates and small cleanups
 	- typec cleanups and fixes based on device testing
 	- device tree updates for usb properties
 	- lots of other small fixes and driver updates.
 
 All of these have been in linux-next for weeks with no reported
 problems.

The second part of the multiplatform changes now converts the
 Intel/Marvell PXA platform along with the rest. The patches went through
 several rebases before the merge window as bugs were found, so they
 remained separate.
 
 This has to touch a lot of drivers, in particular the touchscreen,
 pcmcia, sound and clk bits, to detach the driver files from the
 platform and board specific header files.

Rob Herring fe3f70eec4 dt-bindings: PCI: apple: Add missing 'power-domains' property
The 'unevaluatedProperties' schema checks is not fully working and doesn't
catch some cases where there's a $ref to another schema. A fix is pending,
but results in new warnings in examples.

The Apple PCIe host schema is missing 'power-domains' in the schema.
The example has 3 power domains. However, this is wrong too as actual
dts files have a single power domain and Sven confirmed 1 is correct.

Delay accounting does not track the delay of write-protect copy.  When
tasks trigger many write-protect copys(include COW and unsharing of
anonymous pages[1]), it may spend a amount of time waiting for them.  To
get the delay of tasks in write-protect copy, could help users to evaluate
the impact of using KSM or fork() or GUP.

Bharat Kumar Gogada e2c6170a55 dt-bindings: PCI: xilinx-cpm: Fix reg property order
All existing vendor DTSes are using "cpm_slcr" reg followed by "cfg" reg.

This order is also suggested by node name which is pcie@fca10000 which
suggests that cpm_slcr register should be the first.

Driver itself is using devm_platform_ioremap_resource_byname() for both
names that's why there is no functional change even on description which
are using current order.

But still prefer to change order to cover currently used description.

  There is also a patch to fix an unexpected decompression strategy

  Apart from these, documentation is also updated for a better

  In addition, this has some trivial cleanups without actual code logic

Quite a large number of conversions this time around, courtesy of Uwe
 who has been working tirelessly on these. No drivers of the legacy API
 are left at this point, so as a next step the old API can be removed.
 
 Support is added for a few new devices such as the Xilinx AXI timer-
 based PWMs and the PWM IP found on Sunplus SoCs.
 
 Other than that, there's a number of fixes, cleanups and optimizations.

Linus Torvalds f634b63d43 remoteproc updates for v5.19
This fixes a race condition in the user space interface for starting and
 stopping remote processors, it makes the ELF loader properly skip zero
 memsz segments and it cleans up the debugfs tracefile code a bit by not
 checking for errors.
 
 It introduces support for controlling the audio DSP on Qualcomm MSM8226,
 as well as audio and compute DSPs on Qualcomm SC8280XP.
 
 It makes it possible to specify the firmware path for Mediatek's remote
 processors, fixes a double free in the SCP driver and addresses an issue
 with the SRAM initialization on MT8195.
 
 Lastly it deprecates the custom ELF loader in the iMX remoteproc driver,
 in favor of using the shared one.

  and stopping remote processors, it makes the ELF loader properly skip
  zero memsz segments and it cleans up the debugfs tracefile code a bit
  by not checking for errors.

  It introduces support for controlling the audio DSP on Qualcomm
  MSM8226, as well as audio and compute DSPs on Qualcomm SC8280XP.

  It makes it possible to specify the firmware path for Mediatek's
  remote processors, fixes a double free in the SCP driver and addresses
  an issue with the SRAM initialization on MT8195.

  Lastly it deprecates the custom ELF loader in the iMX remoteproc
  driver, in favor of using the shared one"

Nelson Penn a27e51b45e documentation: Format button_dev as a pointer.
The docs on creating an input device driver have an example in which
button_dev is a pointer to an input_dev struct. However, in two code
snippets below, button_dev is used as if it is not a pointer. Make these
occurrences of button_dev reflect that it is a pointer.

Miguel Ojeda 6199e138fe docs: add SVG version of the Linux logo
In the Rust for Linux patch series, Jonathan Corbet requested [1] that
we avoid binary assets (such as the logo), possibly by recreating
them in SVG format.

However, it turns out there is no SVG version of the Linux logo
in the kernel tree yet, only a GIF one from the pre-v2.0.0 days.

This patch fixes that by adding a SVG version of the Linux logo,
which we could then use in the Rust for Linux documentation and
other similar places.

This is a vector re-illustration by Garrett LeSage of the original
logo by Larry Ewing, plus cleanups by IFo Hancroft.

The file was imported as-is from:

    ecd40de642/tux.svg

The stated license in the repository is:

> Public domain http://creativecommons.org/publicdomain/zero/1.0/
>
> ...but, if anyone asks:
>
> Tux was originally made by Larry Ewing in the Gimp, re-illustrated
> in vector by Garrett LeSage, using Inkscape and refined and
> cleaned up by IFo Hancroft.

Here, the acknowledgement requirement has been made mandatory to
match the wording of the existing GIF logo in `COPYING-logo`.

Both Garrett LeSage and IFo Hancroft gave their permission [2,3]
to use their re-illustration with the license as given in
the `COPYING-logo` file.

Miguel Ojeda fae35da4ac docs: move Linux logo into a new `images` folder
Having assets in the top-level `Documentation` directory can make
it harder to find the documents one needs, especially if we want
to add more of them later on.

Instead, create a new `images` folder inside it that is used
to hold assets such as logos.

In addition, update the reference in `scripts/spdxcheck-test.sh`.

Akira Yokosawa 627f01eab9 docs/conf.py: Cope with removal of language=None in Sphinx 5.0.0
One of the changes in Sphinx 5.0.0 [1] says [sic]:

    5.0.0 final

     - #10474: language does not accept None as it value.
       The default value of language becomes to 'en' now.

[1]: https://www.sphinx-doc.org/en/master/changes.html#release-5-0-0-released-may-30-2022

It results in a new warning from Sphinx 5.0.0 [sic]:

    WARNING: Invalid configuration value found: 'language = None'.
    Update your configuration to a valid langauge code. Falling
    back to 'en' (English).

Silence the warning by using 'en'.
It works with all the Sphinx versions required for building
kernel documentation (1.7.9 or later).

regulator: mt6315-regulator: fix invalid allowed mode
In the binding example, the regulator mode 4 is shown as a valid mode,
but the driver actually only support mode 0 to 2:

This generates an error in dmesg when copy/pasting the binding example:
[    0.306080] vbuck1: invalid regulator-allowed-modes element 4
[    0.307290] vbuck2: invalid regulator-allowed-modes element 4

This commit fixes this error by removing the invalid mode from the
examples.
