drm/sun4i: Use backend/mixer as dedicated DMA device
The sun4i DRM driver deals with DMA constraints in a peculiar way.
Instead of using the actual DMA device in various helpers, it justs
reconfigures the DMA constraints of the virtual display device using
the DMA device's device tree node by calling of_dma_configure().
Turns out of_dma_configure() should only be called from bus code.
Lately this also triggers a big warning through of_iommu_configure()
and ultimately __iommu_probe_device():
late IOMMU probe at driver bind, something fishy here!
Now that the GEM DMA helpers have proper support for allocating
and mapping buffers with a dedicated DMA device, switch over to
it as the proper solution.
The mixer change was tested on a Pine H64 model B. The backend change
was only compile tested. Though I don't expect any issues, help testing
on an older device would be appreciated.

drm/mediatek: Set dedicated DMA device and drop custom GEM callbacks
In commit 9b54a32c7c6a ("drm/mediatek: mtk_gem: Partial refactor and
use drm_gem_dma_object") the MediaTek DRM driver was refactored to use
drm_gem_dma_object, but custom callbacks were still needed to deal with
using the first device of the pipeline as the DMA device, instead of
the MMSYS device that the DRM driver binds to.
Turns out there is already partial support for dedicated DMA devices in
the DRM subsystem for PRIME imports. The preceding patches add support
for dedicated DMA devices to the GEM DMA helpers.
This allows us to just set the dedicated DMA device for the DRM device,
and drop all the custom GEM callbacks. Also drop the .dma_dev field
from the driver private data as it is no longer needed.
There are slight differences in the mmap helper: the VM_DONTDUMP and
VM_IO flags are no longer set. Both were lifted from drm_gem_mmap_obj().
VM_IO probably doesn't make sense since the buffer is allocated using
dma_alloc_attrs().

drm/gem-dma: Support dedicated DMA device for allocation and mapping
Support for a dedicated DMA device for prime imports was added in commit 143ec8d3f939 ("drm/prime: Support dedicated DMA device for dma-buf imports").
This allowed the DRM driver to provide a dedicated DMA device when its
own underlying device was not capable of DMA, for example when it is a
USB device (the original target) or a virtual device. The latter case is
common on embedded SoCs, on which the display pipeline is composed of
various fixed function blocks, and the DRM device is simply a made-up
device, an address space managing the routing between the blocks, or
whichever block the implementor thought made sense at the time. The
point is that the chosen device is often not the actual device doing
the DMA. Various drivers have used workarounds or reimplemented the
GEM DMA helpers to get the DMA addresses and IOMMUs to work correctly.
Add support for the dedicated DMA device to the GEM DMA helpers.
No existing driver currently uses the GEM DMA helpers and calls
drm_dev_set_dma_dev() to set a dedicated DMA device, so no existing
users should be affected.

sched_ext: Use irq_work_queue_on() in schedule_deferred()
schedule_deferred() uses irq_work_queue() which always queues on the
calling CPU. The deferred work can run from any CPU correctly, and the
_locked() path already processes remote rqs from the calling CPU. However,
when falling through to the irq_work path, queuing on the target CPU is
preferable as the work can run sooner via IPI delivery rather than waiting
for the calling CPU to re-enable IRQs.
Currently, only reenqueue operations use this path - either BPF-initiated
reenqueue targeting a remote rq, or IMMED reenqueue when the target CPU is
busy running userspace (not in balance or wakeup, so the _locked() fast
paths aren't available). Use irq_work_queue_on() to target the owning CPU.

ksmbd: fix memory leaks and NULL deref in smb2_lock()
smb2_lock() has three error handling issues after list_del() detaches
smb_lock from lock_list at no_check_cl:
1) If vfs_lock_file() returns an unexpected error in the non-UNLOCK
path, goto out leaks smb_lock and its flock because the out:
handler only iterates lock_list and rollback_list, neither of
which contains the detached smb_lock.
2) If vfs_lock_file() returns -ENOENT in the UNLOCK path, goto out
leaks smb_lock and flock for the same reason. The error code
returned to the dispatcher is also stale.
3) In the rollback path, smb_flock_init() can return NULL on
allocation failure. The result is dereferenced unconditionally,
causing a kernel NULL pointer dereference. Add a NULL check to
prevent the crash and clean up the bookkeeping; the VFS lock
itself cannot be rolled back without the allocation and will be
released at file or connection teardown.
Fix cases 1 and 2 by hoisting the locks_free_lock()/kfree() to before
the if(!rc) check in the UNLOCK branch so all exit paths share one
free site, and by freeing smb_lock and flock before goto out in the
non-UNLOCK branch. Propagate the correct error code in both cases.
Fix case 3 by wrapping the VFS unlock in an if(rlock) guard and adding
a NULL check for locks_free_lock(rlock) in the shared cleanup.

ksmbd: fix use-after-free and NULL deref in smb_grant_oplock()
smb_grant_oplock() has two issues in the oplock publication sequence:
1) opinfo is linked into ci->m_op_list (via opinfo_add) before
add_lease_global_list() is called. If add_lease_global_list()
fails (kmalloc returns NULL), the error path frees the opinfo
via __free_opinfo() while it is still linked in ci->m_op_list.
Concurrent m_op_list readers (opinfo_get_list, or direct iteration
in smb_break_all_levII_oplock) dereference the freed node.
2) opinfo->o_fp is assigned after add_lease_global_list() publishes
the opinfo on the global lease list. A concurrent
find_same_lease_key() can walk the lease list and dereference
opinfo->o_fp->f_ci while o_fp is still NULL.
Fix by restructuring the publication sequence to eliminate post-publish
failure:
- Set opinfo->o_fp before any list publication (fixes NULL deref).
- Preallocate lease_table via alloc_lease_table() before opinfo_add()
so add_lease_global_list() becomes infallible after publication.
- Keep the original m_op_list publication order (opinfo_add before
lease list) so concurrent opens via same_client_has_lease() and
opinfo_get_list() still see the in-flight grant.
- Use opinfo_put() instead of __free_opinfo() on err_out so that
the RCU-deferred free path is used.
This also requires splitting add_lease_global_list() to take a
preallocated lease_table and changing its return type from int to void,
since it can no longer fail.

- patch 1 improves one of the CTokenizer unit test, fixing some
potential issues on it;
- patches 2 and 3 contain some improvement/fixes for Sphinx

- The remaining patches:
- create a new class for kernel-doc config;
- fix some internal representations of KdocItem;
- add unit tests for KernelDoc() parser class;
- add support to output KdocItem in YAML, which is a

docs: test_kdoc_parser: add support for dynamic test creation
Use the content of kdoc-test.yaml to generate unittests to
verify that kernel-doc internal methods are parsing C code
and generating output the expected way.
Depending on what is written at the parser file at
kdoc-test.yaml, up to 5 tests can be generated from a single
test entry inside the YAML file:
1. from source to kdoc_item: test KernelDoc class;
2. from kdoc_item to man: test ManOutput class;
3. from kdoc_item to rst: test RestOutput class;
4. from source to man without checking expected KdocItem;
5. from source to rst without checking expected KdocItem.
docs: add a simple kdoc-test.yaml together with a validation tool
Create a simple kdoc-test.yaml to be used to create unit tests for

For now, all we want is a simple function mapped on a yaml test
using the defined schema.
To be sure that the schema is followed, add an unittest for
the file, which will also validate that the schema is properly
parsed.
It should be noticed that the .TH definition for the man format
contains a timestamp. We'll need to handle that when dealing with
the actual implementation for the ManOutput class unit tests.
docs: unittests: add a parser to test kernel-doc parser logic
Validating that kernel-doc is parsing data properly is tricky.
Add an unittest skeleton that alllows passing a source code
and check if the corresponding values of export_table and
entries returned by the parser are properly filled.
It works by mocking a file input with the contents of a source
string, an comparing if:
- exports set matches;
- expected KernelItem entries match.
Create a new TestSelfValidate meant to check if the logic
inside KdocParser.run_test() does its job of checking for
differences inside KdocItem.
docs: kdoc_item: add support to generate a KdocItem from a dict
When reading the contents on a KdocItem using YAML, the data
will be imported into a dict.
Add a method to create a new KdocItem from a dict to allow
converting such input into a real KdocItem.
While here, address an issue that, if the class is initialized
with an internal parameter outside the 4 initial arguments,
it would end being added inside other_stuff, which breaks
initializing it from a dict.

the logic with handles a series of KdocItem symbols from
a single file belons to kdoc_output, and not to kdoc_files.

While here, also ensure that self.config will be placed
together with set.out_style.

This patch series change how kdoc parser handles macro replacements.
Instead of heavily relying on regular expressions that can sometimes
be very complex, it uses a C lexical tokenizer. This ensures that
BEGIN/END blocks on functions and structs are properly handled,
even when nested.
Checking before/after the patch series, for both man pages and
rst only had:
- whitespace differences;
- struct_group macros now are shown as inner anonimous structs
as it should be.
Also, I didn't notice any relevant change on the documentation build
time. With that regards, right now, every time a CMatch replacement
rule takes in place, it does:
for each transform:
- tokenizes the source code;
- handle CMatch;
- convert tokens back to a string.
A possible optimization would be to do, instead:
- tokenizes source code;
- for each transform handle CMatch;
- convert tokens back to a string.
For now, I opted not do do it, because:
- too much changes on a single row;
- docs build time is taking ~3:30 minutes, which is
about the same time it ws taken before the changes;
- there is a very dirty hack inside function_xforms:
(KernRe(r"_noprof"), ""). This is meant to change
function prototypes instead of function arguments.
So, if ok for you, I would prefer to merge this one first. We can later
optimize kdoc_parser to avoid multiple token <-> string conversions.

docs: kdoc: ensure that comments are dropped before calling split_struct_proto()
Changeset 2b957decdb6c ("docs: kdoc: don't add broken comments inside prototypes")
revealed a hidden bug at split_struct_proto(): some comments there may break
its capability of properly identifying a struct.
Fixing it is as simple as stripping comments before calling it.
The CMatch logic is complex enough to justify tests to ensure
that it is doing its job.
Add unittests to check the functionality provided by CMatch
by replicating expected patterns.
The CMatch class handles with complex macros. Add an unittest
to check if its doing the right thing and detect eventual regressions
as we improve its code.
The initial version was generated using gpt-oss:latest LLM
on my local GPU, as LLMs aren't bad transforming patterns
into unittests.
Yet, the curent version contains only the skeleton of what
LLM produced, as I ended higly changing its content to be
more representative and to have real case scenarios.
The kdoc_xforms test suite contains 3 test groups. Two of
them tests the basic functionality of CMatch to
replace patterns.
The last one (TestRealUsecases) contains real code snippets
from the Kernel with some cleanups to better fit in 80 columns
and uses the same transforms as kernel-doc, thus allowing
to test the logic used inside kdoc_parser to transform
functions, structs and variable patterns.
Its output is like this:

Handling C code purely using regular expressions doesn't work well.
Add a C tokenizer to help doing it the right way.
The tokenizer was written using as basis the Python re documentation
tokenizer example from:
https://docs.python.org/3/library/re.html#writing-a-tokenizer
Parsing a file like drivers/scsi/isci/host.h, which contains
broken kernel-doc markups makes it create a prototype that contains
unmatched end comments.
That causes, for instance, struct sci_power_control to be shown this
this prototype:

*/ struct sci_timer timer;
* requesters field. */ u8 phys_waiting;
*/ u8 phys_granted_power;
* mapped into requesters via struct sci_phy.phy_index */ struct isci_phy *requesters[SCI_MAX_PHYS];

Fix the logic to detect such cases, and keep adding the comments
inside it.

While python internal libraries have support for unit tests, its

internally. The initial skeleton was generated with the help of
LLM tools, but it was higly modified to ensure that it will work

Pull tracing fixes from Steven Rostedt:
- Revert "tracing: Remove pid in task_rename tracing output"
A change was made to remove the pid field from the task_rename event
because it was thought that it was always done for the current task
and recording the pid would be redundant. This turned out to be
incorrect and there are a few corner case where this is not true and
caused some regressions in tooling.
- Fix the reading from user space for migration
The reading of user space uses a seq lock type of logic where it uses
a per-cpu temporary buffer and disables migration, then enables
preemption, does the copy from user space, disables preemption,
enables migration and checks if there was any schedule switches while
preemption was enabled. If there was a context switch, then it is
considered that the per-cpu buffer could be corrupted and it tries
again. There's a protection check that tests if it takes a hundred
tries, it issues a warning and exits out to prevent a live lock.
This was triggered because the task was selected by the load balancer
to be migrated to another CPU, every time preemption is enabled the
migration task would schedule in try to migrate the task but can't
because migration is disabled and let it run again. This caused the
scheduler to schedule out the task every time it enabled preemption
and made the loop never exit (until the 100 iteration test
triggered).
Fix this by enabling and disabling preemption and keeping migration
enabled if the reading from user space needs to be done again. This
will let the migration thread migrate the task and the copy from user
space will likely pass on the next iteration.
- Fix trace_marker copy option freeing
The "copy_trace_marker" option allows a tracing instance to get a
copy of a write to the trace_marker file of the top level instance.
This is managed by a link list protected by RCU. When an instance is
removed, a check is made if the option is set, and if so
synchronized_rcu() is called.
The problem is that an iteration is made to reset all the flags to
what they were when the instance was created (to perform clean ups)
was done before the check of the copy_trace_marker option and that
option was cleared, so the synchronize_rcu() was never called.
Move the clearing of all the flags after the check of
copy_trace_marker to do synchronize_rcu() so that the option is still
set if it was before and the synchronization is performed.
- Fix entries setting when validating the persistent ring buffer
When validating the persistent ring buffer on boot up, the number of
events per sub-buffer is added to the sub-buffer meta page. The
validator was updating cpu_buffer->head_page (the first sub-buffer of
the per-cpu buffer) and not the "head_page" variable that was
iterating the sub-buffers. This was causing the first sub-buffer to
be assigned the entries for each sub-buffer and not the sub-buffer
that was supposed to be updated.
- Use "hash" value to update the direct callers
When updating the ftrace direct callers, it assigned a temporary
callback to all the callback functions of the ftrace ops and not just
the functions represented by the passed in hash. This causes an
unnecessary slow down of the functions of the ftrace_ops that is not
being modified. Only update the functions that are going to be
modified to call the ftrace loop function so that the update can be
made on those functions.

drm/mediatek: Remove all conflicting aperture devices during probe
If a device has a framebuffer available it might be already used as
display by simple-framebuffer or simpledrm when mediatek-drm is probed.
This is actually helpful when porting to a new device as
framebuffers are simple to setup in device trees and fbcon can be
used to monitor the kernel boot process.
When drm-mediatek loads a new fb device is initialized, however
fbcon remains attached to the initial framebuffer which is no longer
connected to the actual display - the early fb is never removed.
We can gracefully transition from framebuffer handling to drm-managed
display by calling aperture_remove_all_conflicting_devices before
registering mediatek-drm. This takes care of unloading other fb
devices/drivers and disconnects fbcon which then automatically
reconnects to mediatekdrmfb as soon as it's available.
The function is invoked just before drm_dev_register() to kick out
the existing framebuffer as late as possible to reduce the time the
screen is unresponsive.
