Note the behaviour of kasan.fault=panic_on_write for async modes, since
all asynchronous faults will result in panic (even if they are reads).

The recommended ways for getting DAMON monitoring results are using
tried_regions sysfs directory for partial snapshot of the results, and
DAMON tracepoint for full record of the results. However, the
tried_regions sysfs directory usage has not sufficiently updated on some
sections of the DAMON usage document. Update those.

Patch series "Docs/{mm,admin-guide}damon: update design and usage docs".
Update DAMON design and usage documents for outdated and unnecessarily
duplicated parts.
This patch (of 7):
The 'age' of each region in DAMON monitoring results is an important
concept for both monitoring part and DAMOS. And DAMOS section of the
design document is mentioning it. However, the age itself is not
explained in the document. Add a section for that.

KASAN's boot time kernel parameter 'kasan.fault=' currently supports
'report' and 'panic', which results in either only reporting bugs or also
panicking on reports.
However, some users may wish to have more control over when KASAN reports
result in a kernel panic: in particular, KASAN reported invalid _writes_
are of special interest, because they have greater potential to corrupt
random kernel memory or be more easily exploited.
To panic on invalid writes only, introduce 'kasan.fault=panic_on_write',
which allows users to choose to continue running on invalid reads, but
panic only on invalid writes.

Make pte_offset_map() a wrapper for __pte_offset_map() (optionally outputs
pmdval), pte_offset_map_lock() a sparse __cond_lock wrapper for
__pte_offset_map_lock(): those __funcs added in mm/pgtable-generic.c.
__pte_offset_map() do pmdval validation (including pmd_clear_bad() when
pmd_bad()), returning NULL if pmdval is not for a page table.
__pte_offset_map_lock() verify pmdval unchanged after getting the lock,
trying again if it changed.
No #ifdef CONFIG_TRANSPARENT_HUGEPAGE around them: that could be done to
cover the imminent case, but we expect to generalize it later, and it
makes a mess of where to do the pmd_bad() clearing.
Add pte_offset_map_nolock(): outputs ptl like pte_offset_map_lock(),
without actually taking the lock. This will be preferred to open uses of
pte_lockptr(), because (when split ptlock is in page table's struct page)
it points to the right lock for the returned pte pointer, even if *pmd
gets changed racily afterwards.
Update corresponding Documentation.
Do not add the anticipated rcu_read_lock() and rcu_read_unlock()s yet:
they have to wait until all architectures are balancing pte_offset_map()s
with pte_unmap()s (as in the arch series posted earlier). But comment
where they will go, so that it's easy to add them for experiments. And
only when those are in place can transient racy failure cases be enabled.
Add more safety for the PAE mismatched pmd_low pmd_high case at that time.

one is supposed to build selftests:
make headers && make -C tools/testing/selftests/mm
However, that's not yet documented anywhere. So add it to

Patch series "Docs/mm/damon: Minor fixes and design doc update".
Some of the DAMON documents are outdated, or having minor typos or grammar
erros. Especially, the design doc has not updated for DAMOS, which is an
important part of DAMON. Fix the minor issues and update documents.
This patch (of 10):
The first two questions of DAMON faqs have raised when DAMON patches were
first submitted. More than one year has passed since DAMON patches get
merged in the mainline, and that kind of questions are not asked nowadays.
Remove the questions.

This patch is similar to commit 8e20d4b33266 ("mm/memcontrol: export
memcg->watermark via sysfs for v2 memcg"), but exports the swap counter's
watermark.
We allocate jobs to our compute farm using heuristics determined by memory
and swap usage from previous jobs. Tracking the peak swap usage for new
jobs is important for determining when jobs are exceeding their expected
bounds, or when our baseline metrics are getting outdated.
Our toolset was written to use the "memory.memsw.max_usage_in_bytes" file
in cgroups v1, and altering it to poll cgroups v2's "memory.swap.current"
would give less accurate results as well as add complication to the code.
Having this watermark exposed in sysfs is much preferred.

Pull tracing fixes from Steven Rostedt:
"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"

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.

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.

- 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

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'

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.
