Ruihan Li 81a31a860b mm: page_table_check: Make it dependent on EXCLUSIVE_SYSTEM_RAM
Without EXCLUSIVE_SYSTEM_RAM, users are allowed to map arbitrary
physical memory regions into the userspace via /dev/mem. At the same
time, pages may change their properties (e.g., from anonymous pages to
named pages) while they are still being mapped in the userspace, leading
to "corruption" detected by the page table check.

To avoid these false positives, this patch makes PAGE_TABLE_CHECK
depends on EXCLUSIVE_SYSTEM_RAM. This dependency is understandable
because PAGE_TABLE_CHECK is a hardening technique but /dev/mem without
STRICT_DEVMEM (i.e., !EXCLUSIVE_SYSTEM_RAM) is itself a security
problem.

Even with EXCLUSIVE_SYSTEM_RAM, I/O pages may be still allowed to be
mapped via /dev/mem. However, these pages are always considered as named
pages, so they won't break the logic used in the page table check.

Linus Torvalds 8b817fded4 Tracing fixes:
User events:
 
  - Use long instead of int for storing the enable set/clear bit, as it was
    found that big endian machines could end up using the wrong bits.
 
  - Split allocating mm and attaching it. This keeps the allocation separate
    from the registration and avoids various races.
 
  - Remove RCU locking around pin_user_pages_remote() as that can schedule. The
    RCU protection is no longer needed with the above split of mm allocation and
    attaching.
 
  - Rename the "link" fields of the various structs to something more
    meaningful.
 
  - Add comments around user_event_mm struct usage and locking requirements.
 
 Timerlat tracer:
 
  - Fix missed wakeup of timerlat thread caused by the timerlat interrupt
    triggering when tracing is off. The timer interrupt handler needs to always
    wake up the timerlat thread regardless if tracing is enabled or not,
    otherwise, it will never wake up.
 
 Histograms:
 
  - Fix regression of breaking the "stacktrace" modifier for variables. That
    modifier cannot be used for values, but can be used for variables that are
    passed from one histogram to the next. This was broken when adding the
    restriction to values as the variable logic used the same code.
 
  - Rename the special field "stacktrace" to "common_stacktrace". Special fields
    (that are not actually part of the event, but can act just like event
    fields, like 'comm' and 'timestamp') should be prefixed with 'common_' for
    consistency. To keep backward compatibility, 'stacktrace' can still be used
    (as with the special field 'cpu'), but can be overridden if the event has a
    field called 'stacktrace'.
 
  - Update the synthetic event selftests to use the new name (synthetic events
    are created by histograms)
 
 Tracing bootup selftests:
 
  - Reorganize the code to keep artifacts of the selftests not compiled in when
    selftests are not configured.
 
  - Add various cond_resched() around the selftest code, as the softlock
    watchdog was triggering much more often. It appears that the kernel runs
    slower now with full debugging enabled.
 
  - While debugging ftrace with ftrace (using an instance ring buffer instead of
    the top level one), I found that the selftests were disabling prints to the
    debug instance. This should not happen, as the selftests only disable
    printing to the main buffer as the selftests examine the main buffer to see
    if it has what it expects, and prints can make the tests fail. Make the
    selftests only disable printing to the toplevel buffer, and leave the
    instance buffers alone.

Linus Torvalds 18713e8a68 ARM: SoC fixes for 6.4
There have not been a lot of fixes for for the soc tree in 6.4, but
 these have been sitting here for too long.
 
 For the devicetree side, there is one minor warning fix for vexpress,
 the rest all all for the the NXP i.MX platforms: SoC specific bugfixes
 for the iMX8 clocks and its USB-3.0 gadget device, as well as board
 specific fixes for regulators and the phy on some of the i.MX boards.
 
 The microchip risc-v and arm32 maintainers now also add a shared
 maintainer file entry for the arm64 parts.
 
 The remaining fixes are all for firmware drivers, addressing mistakes in
 the optee, scmi and ff-a firmware driver implementation, mostly in the
 error handling code, incorrect use of the alloc_workqueue() interface in
 SCMI, and compatibility with corner cases of the firmware implementation.

We had a good run, but after 4 weeks of use we heard someone
asking about pw-bot commands. Let's explain its existence
in the docs. It's not a complete documentation but hopefully
it's enough for the casual contributor. The project and scope
are in flux so the details would likely become out of date,
if we were to document more in depth.

Steven Rostedt (Google) 4b512860bd tracing: Rename stacktrace field to common_stacktrace
The histogram and synthetic events can use a pseudo event called
"stacktrace" that will create a stacktrace at the time of the event and
use it just like it was a normal field. We have other pseudo events such
as "common_cpu" and "common_timestamp". To stay consistent with that,
convert "stacktrace" to "common_stacktrace". As this was used in older
kernels, to keep backward compatibility, this will act just like
"common_cpu" did with "cpu". That is, "cpu" will be the same as
"common_cpu" unless the event has a "cpu" field. In which case, the
event's field is used. The same is true with "stacktrace".

Also update the documentation to reflect this change.

Linus Torvalds ac92c27935 s390 updates for 6.4-rc3
- Add check whether the required facilities are installed
   before using the s390-specific ChaCha20 implementation.
 
 - Key blobs for s390 protected key interface IOCTLs commands
   PKEY_VERIFYKEY2 and PKEY_VERIFYKEY3 may contain clear key
   material. Zeroize copies of these keys in kernel memory
   after creating protected keys.
 
 - Set CONFIG_INIT_STACK_NONE=y in defconfigs to avoid extra
   overhead of initializing all stack variables by default.
 
 - Make sure that when a new channel-path is enabled all
   subchannels are evaluated: with and without any devices
   connected on it.
 
 - When SMT thread CPUs are added to CPU topology masks the
   nr_cpu_ids limit is not checked and could be exceeded.
   Respect the nr_cpu_ids limit and avoid a warning when
   CONFIG_DEBUG_PER_CPU_MAPS is set.
 
 - The pointer to IPL Parameter Information Block is stored
   in the absolute lowcore as a virtual address. Save it as
   the physical address for later use by dump tools.
 
 - Fix a Queued Direct I/O (QDIO) problem on z/VM guests using
   QIOASSIST with dedicated (pass through) QDIO-based devices
   such as FCP, real OSA or HiperSockets.
 
 - s390's struct statfs and struct statfs64 contain padding,
   which field-by-field copying does not set. Initialize the
   respective structures with zeros before filling them and
   copying to userspace.
 
 - Grow s390 compat_statfs64, statfs and statfs64 structures
   f_spare array member to cover padding and simplify things.
 
 - Remove obsolete SCHED_BOOK and SCHED_DRAWER configs.
 
 - Remove unneeded S390_CCW_IOMMU and S390_AP_IOM configs.

msm-fixes for v6.4-rc3

Display Fixes:

+ Catalog fixes:
 - fix the programmable fetch lines and qos settings of msm8998
   to match what is present downstream
 - fix the LM pairs for msm8998 to match what is present downstream.
   The current settings are not right as LMs with incompatible
   connected blocks are paired
 - remove unused INTF0 interrupt mask from SM6115/QCM2290 as there
   is no INTF0 present on those chipsets. There is only one DSI on
   index 1
 - remove TE2 block from relevant chipsets because this is mainly
   used for ping-pong split feature which is not supported upstream
   and also for the chipsets where we are removing them in this
   change, that block is not present as the tear check has been moved
   to the intf block
 - relocate non-MDP_TOP INTF_INTR offsets from dpu_hwio.h to
   dpu_hw_interrupts.c to match where they belong
 - fix the indentation for REV_7xxx interrupt masks
 - fix the offset and version for dither blocks of SM8[34]50/SC8280XP
   chipsets as it was incorrect
 - make the ping-pong blk length 0 for appropriate chipsets as those
   chipsets only have a dither ping-pong dither block but no other
   functionality in the base ping-pong
 - remove some duplicate register defines from INTF
+ Fix the log mask for the writeback block so that it can be enabled
  correctly via debugfs
+ unregister the hdmi codec for dp during unbind otherwise it leaks
  audio codec devices
+ Yaml change to fix warnings related to 'qcom,master-dsi' and
  'qcom,sync-dual-dsi'

GPU Fixes:

+ fix submit error path leak
+ arm-smmu-qcom fix for regression that broke per-process page tables
+ fix no-iommu crash

Jason Gunthorpe 0f1cbf941d s390/iommu: get rid of S390_CCW_IOMMU and S390_AP_IOMMU
These don't do anything anymore, the only user of the symbol was
VFIO_CCW/AP which already "depends on VFIO" and VFIO itself selects
IOMMU_API.

When this was added VFIO was wrongly doing "depends on IOMMU_API" which
required some contortions like this to ensure IOMMU_API was turned on.

  one command less to execute. This led to a few small adjustments to
  the text and the flow in the surrounding area.

* fix two thinkos in the section explaining full git clones

Frank Li 50a1726b14 dt-binding: cdns,usb3: Fix cdns,on-chip-buff-size type
In cdns3-gadget.c, 'cdns,on-chip-buff-size' was read using
device_property_read_u16(). It resulted in 0 if a 32bit value was used
in dts. This commit fixes the dt binding doc to declare it as u16.

Douglas Anderson 43cd3ddbff dt-bindings: interrupt-controller: arm,gic-v3: Add quirk for Mediatek SoCs w/ broken FW
When trying to turn on the "pseudo NMI" kernel feature in Linux, it
was discovered that all Mediatek-based Chromebooks that ever shipped
(at least ones with GICv3) had a firmware bug where they wouldn't save
certain GIC "GICR" registers properly. If a processor ever entered a
suspend/idle mode where the GICR registers lost state then they'd be
reset to their default state.

As a result of the bug, if you try to enable "pseudo NMIs" on the
affected devices then certain interrupts will unexpectedly get
promoted to be "pseudo NMIs" and cause crashes / freezes / general
mayhem.

ChromeOS is looking to start turning on "pseudo NMIs" in production to
make crash reports more actionable. To do so, we will release firmware
updates for at least some of the affected Mediatek Chromebooks.
However, even when we update the firmware of a Chromebook it's always
possible that a user will end up booting with old firmware. We need to
be able to detect when we're running with firmware that will crash and
burn if pseudo NMIs are enabled.

The current plan is:
* Update the device trees of all affected Chromebooks to include the
  'mediatek,broken-save-restore-fw' property. The kernel can use this
  to know not to enable certain features like "pseudo NMI". NOTE:
  device trees for Chromebooks are never baked into the firmware but
  are bundled with the kernel. A kernel will never be configured to
  use "pseudo NMIs" and be bundled with an old device tree.
* When we get a fixed firmware for one of these Chromebooks, it will
  patch the device tree to remove this property.

For some details, you can also see the public bug

Dario Binacchi caf78f0f49 dt-bindings: net: can: add "st,can-secondary" property
On the stm32f7 Socs the can peripheral can be in single or dual
configuration. In the dual configuration, in turn, it can be in primary
or secondary mode. The addition of the 'st,can-secondary' property allows
you to specify this mode in the dual configuration.

CAN peripheral nodes in single configuration contain neither
"st,can-primary" nor "st,can-secondary".
