Pull more tracing fixes from Steven Rostedt:
- Fix regression of waiting a long time on updating trace event filters
When the faultable trace points were added, it needed task trace RCU
synchronization.
This was added to the tracepoint_synchronize_unregister() function.
The filter logic always called this function whenever it updated the
trace event filters before freeing the old filters. This increased
the time of "trace-cmd record" from taking 13 seconds to running over
2 minutes to complete.
Move the freeing of the filters to call_rcu*() logic, which brings
the time back down to 13 seconds.
- Fix ring_buffer_subbuf_order_set() error path lock protection
The error path of the ring_buffer_subbuf_order_set() released the
mutex too early and allowed subsequent accesses to setting the
subbuffer size to corrupt the data and cause a bug.
By moving the mutex locking to the end of the error path, it prevents
the reentrant access to the critical data and also allows the
function to convert the taking of the mutex over to the guard()
logic.
- Remove unused power management clock events
The clock events were added in 2010 for power management. In 2011 arm
used them. In 2013 the code they were used in was removed. These
events have been wasting memory since then.
- Fix sparse warnings
There was a few places that sparse warned about trace_events_filter.c
where file->filter was referenced directly, but it is annotated with
an __rcu tag. Use the helper functions and fix them up to use
rcu_dereference() properly.
* tag 'trace-v6.16-3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace:

Intention for MNT_LOCKED had always been to protect the internal
mountpoints within a subtree that got copied across the userns boundary,
not the mountpoint that tree got attached to - after all, it _was_
exposed before the copying.
For roots of secondary copies that is enforced in attach_recursive_mnt() -
MNT_LOCKED is explicitly stripped for those. For the root of primary
copy we are almost always guaranteed that MNT_LOCKED won't be there,
so attach_recursive_mnt() doesn't bother. Unfortunately, one call
chain got overlooked - triggering e.g. NFS referral will have the
submount inherit the public flags from parent; that's fine for such
things as read-only, nosuid, etc., but not for MNT_LOCKED.
This is particularly pointless since the mount attached by finish_automount()
is usually expirable, which makes any protection granted by MNT_LOCKED
null and void; just wait for a while and that mount will go away on its own.
Include MNT_LOCKED into the set of flags to be ignored by do_add_mount() - it
really is an internal flag.

The events clock_enable, clock_disable, and clock_set_rate were added back
in 2010. In 2011 they were used by the arm architecture but removed in
2013. These events add around 7K of memory which was wasted for the last 12
years.
Remove them.

Pull USB / Thunderbolt updates from Greg KH:
"Here is the big set of USB and Thunderbolt changes for 6.16-rc1.
Included in here are the following:
- USB offload support for audio devices.
I think this takes the record for the most number of patch series
(30+) over the longest period of time (2+ years) to get merged
properly.
Many props go to Wesley Cheng for seeing this effort through, they
took a major out-of-tree hacked-up-monstrosity that was created by
multiple vendors for their specific devices, got it all merged into
a semi-coherent set of changes, and got all of the different major
subsystems to agree on how this should be implemented both with
changes to their code as well as userspace apis, AND wrangled the
hardware companies into agreeing to go forward with this, despite
making them all redo work they had already done in their private
device trees.
This feature offers major power savings on embedded devices where a
USB audio stream can continue to flow while the rest of the system
is sleeping, something that devices running on battery power really
care about. There are still some more small tweaks left to be done
here, and those patches are still out for review and arguing among
the different hardware companies, but this is a major step forward
and a great example of how to do upstream development well.
- small number of thunderbolt fixes and updates, things seem to be
slowing down here (famous last words...)
- xhci refactors and reworking to try to handle some rough corner
cases in some hardware implementations where things don't always
work properly
- typec driver updates
- USB3 power management reworking and updates
- Removal of some old and orphaned UDC gadget drivers that had not
been used in a very long time, dropping over 11 thousand lines from
the tree, always a nice thing, making up for the 12k lines added
for the USB offload feature.
- lots of little updates and fixes in different drivers
All of these have been in linux-next for over 2 weeks, the USB offload
logic has been in there for 8 weeks now, with no reported issues"

Currently, __split_vma() triggers hugetlb page table unsharing through
vm_ops->may_split(). This happens before the VMA lock and rmap locks are
taken - which is too early, it allows racing VMA-locked page faults in our
process and racing rmap walks from other processes to cause page tables to
be shared again before we actually perform the split.
Fix it by explicitly calling into the hugetlb unshare logic from
__split_vma() in the same place where THP splitting also happens. At that
point, both the VMA and the rmap(s) are write-locked.
An annoying detail is that we can now call into the helper
hugetlb_unshare_pmds() from two different locking contexts:
1. from hugetlb_split(), holding:
- mmap lock (exclusively)
- VMA lock
- file rmap lock (exclusively)
2. hugetlb_unshare_all_pmds(), which I think is designed to be able to
call us with only the mmap lock held (in shared mode), but currently
only runs while holding mmap lock (exclusively) and VMA lock
Backporting note:
This commit fixes a racy protection that was introduced in commit
b30c14cd6102 ("hugetlb: unshare some PMDs when splitting VMAs"); that
commit claimed to fix an issue introduced in 5.13, but it should actually
also go all the way back.

Failures inside codetag_load_module() are currently ignored. As a result
an error there would not cause a module load failure and freeing of the
associated resources. Correct this behavior by propagating the error code
to the caller and handling possible errors. With this change, error to
allocate percpu counters, which happens at this stage, will not be ignored
and will cause a module load failure and freeing of resources. With this
change we also do not need to disable memory allocation profiling when
this error happens, instead we fail to load the module.

The __mod_device_table__* symbols are only parsed by modpost to generate
MODULE_ALIAS() entries from MODULE_DEVICE_TABLE().
Therefore, these symbols do not need to be globally visible, or globally
unique.
If they are in the global scope, we would worry about the symbol
uniqueness, but modpost is fine with parsing multiple symbols with the
same name.

The following ftrace patch for riscv uses a data store to update ftrace
function. Therefore, a romote fence is required to order it against
function_trace_op updates. The mechanism is similar to the fence between
function_trace_op and update_ftrace_func in the generic ftrace, so we
leverage the same ftrace_sync_ipi function.

The expected flow of operations when using PXP is to query the PXP
status and wait for it to transition to "ready" before attempting to
create an exec_queue. This flow is followed by the Mesa driver, but
there is no guarantee that an incorrectly coded (or malicious) app
will not attempt to create the queue first without querying the status.
Therefore, we need to clarify what the expected behavior of the queue
creation ioctl is in this scenario.
Currently, the ioctl always fails with an -EBUSY code no matter the
error, but for consistency it is better to distinguish between "failed
to init" (-EIO) and "not ready" (-EBUSY), the same way the query ioctl
does. Note that, while this is a change in the return code of an ioctl,
the behavior of the ioctl in this particular corner case was not clearly
spec'd, so no one should have been relying on it (and we know that Mesa,
which is the only known userspace for this, didn't).

S1G beacons are not traditional beacons but a type of extension frame.
Extension frames contain the frame control and duration fields, followed
by zero or more optional fields before the frame body. These optional
fields are distinct from the variable length elements.
The presence of optional fields is indicated in the frame control field.
To correctly locate the elements offset, the frame control must be parsed
to identify which optional fields are present. Currently, mac80211 parses
S1G beacons based on fixed assumptions about the frame layout, without
inspecting the frame control field. This can result in incorrect offsets
to the "variable" portion of the frame.
Properly parse S1G beacon frames by using the field lengths defined in
IEEE 802.11-2024, section 9.3.4.3, ensuring that the elements offset is
calculated accurately.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Print the actual delay time in pci_bridge_wait_for_secondary_bus()
instead of assuming it was 1000ms (Wilfred Mallawa)
- Revert 'iommu/amd: Prevent binding other PCI drivers to IOMMU PCI
devices', which broke resume from system sleep on AMD platforms and
has been fixed by other commits (Lukas Wunner)
Resource management:
- Remove mtip32xx use of pcim_iounmap_regions(), which is deprecated
and unnecessary (Philipp Stanner)
- Remove pcim_iounmap_regions() and pcim_request_region_exclusive()
and related flags since all uses have been removed (Philipp
Stanner)
- Rework devres 'request' functions so they are no longer 'hybrid',
i.e., their behavior no longer depends on whether
pcim_enable_device or pci_enable_device() was used, and remove
related code (Philipp Stanner)
- Warn (not BUG()) about failure to assign optional resources (Ilpo
Järvinen)
Error handling:
- Log the DPC Error Source ID only when it's actually valid (when
ERR_FATAL or ERR_NONFATAL was received from a downstream device)
and decode into bus/device/function (Bjorn Helgaas)
- Determine AER log level once and save it so all related messages
use the same level (Karolina Stolarek)
- Use KERN_WARNING, not KERN_ERR, when logging PCIe Correctable
Errors (Karolina Stolarek)
- Ratelimit PCIe Correctable and Non-Fatal error logging, with sysfs
controls on interval and burst count, to avoid flooding logs and
RCU stall warnings (Jon Pan-Doh)
Power management:
- Increment PM usage counter when probing reset methods so we don't
try to read config space of a powered-off device (Alex Williamson)
- Set all devices to D0 during enumeration to ensure ACPI opregion is
connected via _REG (Mario Limonciello)
Power control:
- Rename pwrctrl Kconfig symbols from 'PWRCTL' to 'PWRCTRL' to match
the filename paths. Retain old deprecated symbols for
compatibility, except for the pwrctrl slot driver
(PCI_PWRCTRL_SLOT) (Johan Hovold)
- When unregistering pwrctrl, cancel outstanding rescan work before
cleaning up data structures to avoid use-after-free issues (Brian
Norris)
Bandwidth control:
- Simplify link bandwidth controller by replacing the count of Link
Bandwidth Management Status (LBMS) events with a PCI_LINK_LBMS_SEEN
flag (Ilpo Järvinen)
- Update the Link Speed after retraining, since the Link Speed may
have changed (Ilpo Järvinen)
PCIe native device hotplug:
- Ignore Presence Detect Changed caused by DPC.
pciehp already ignores Link Down/Up events caused by DPC, but on
slots using in-band presence detect, DPC causes a spurious Presence
Detect Changed event (Lukas Wunner)
- Ignore Link Down/Up caused by Secondary Bus Reset.
On hotplug ports using in-band presence detect, the reset causes a
Presence Detect Changed event, which mistakenly caused teardown and
re-enumeration of the device. Drivers may need to annotate code
that resets their device (Lukas Wunner)
Virtualization:
- Add an ACS quirk for Loongson Root Ports that don't advertise ACS
but don't allow peer-to-peer transactions between Root Ports; the
quirk allows each Root Port to be in a separate IOMMU group (Huacai
Chen)
Endpoint framework:
- For fixed-size BARs, retain both the actual size and the possibly
larger size allocated to accommodate iATU alignment requirements
(Jerome Brunet)
- Simplify ctrl/SPAD space allocation and avoid allocating more space
than needed (Jerome Brunet)
- Correct MSI-X PBA offset calculations for DesignWare and Cadence
endpoint controllers (Niklas Cassel)
- Align the return value (number of interrupts) encoding for
pci_epc_get_msi()/pci_epc_ops::get_msi() and
pci_epc_get_msix()/pci_epc_ops::get_msix() (Niklas Cassel)
- Align the nr_irqs parameter encoding for
pci_epc_set_msi()/pci_epc_ops::set_msi() and
pci_epc_set_msix()/pci_epc_ops::set_msix() (Niklas Cassel)
Common host controller library:
- Convert pci-host-common to a library so platforms that don't need
native host controller drivers don't need to include these helper
functions (Manivannan Sadhasivam)
Apple PCIe controller driver:
- Extract ECAM bridge creation helper from pci_host_common_probe() to
separate driver-specific things like MSI from PCI things (Marc
Zyngier)
- Dynamically allocate RID-to_SID bitmap to prepare for SoCs with
varying capabilities (Marc Zyngier)
- Skip ports disabled in DT when setting up ports (Janne Grunau)
- Add t6020 compatible string (Alyssa Rosenzweig)
- Add T602x PCIe support (Hector Martin)
- Directly set/clear INTx mask bits because T602x dropped the
accessors that could do this without locking (Marc Zyngier)
- Move port PHY registers to their own reg items to accommodate
T602x, which moves them around; retain default offsets for existing
DTs that lack phy%d entries with the reg offsets (Hector Martin)
- Stop polling for core refclk, which doesn't work on T602x and the
bootloader has already done anyway (Hector Martin)
- Use gpiod_set_value_cansleep() when asserting PERST# in probe
because we're allowed to sleep there (Hector Martin)
Cadence PCIe controller driver:
- Drop a runtime PM 'put' to resolve a runtime atomic count underflow
(Hans Zhang)
- Make the cadence core buildable as a module (Kishon Vijay Abraham I)
- Add cdns_pcie_host_disable() and cdns_pcie_ep_disable() for use by
loadable drivers when they are removed (Siddharth Vadapalli)
Freescale i.MX6 PCIe controller driver:
- Apply link training workaround only on IMX6Q, IMX6SX, IMX6SP
(Richard Zhu)
- Remove redundant dw_pcie_wait_for_link() from
imx_pcie_start_link(); since the DWC core does this, imx6 only
needs it when retraining for a faster link speed (Richard Zhu)
- Toggle i.MX95 core reset to align with PHY powerup (Richard Zhu)
- Set SYS_AUX_PWR_DET to work around i.MX95 ERR051624 erratum: in
some cases, the controller can't exit 'L23 Ready' through Beacon or
PERST# deassertion (Richard Zhu)
- Clear GEN3_ZRXDC_NONCOMPL to work around i.MX95 ERR051586 erratum:
controller can't meet 2.5 GT/s ZRX-DC timing when operating at 8
GT/s, causing timeouts in L1 (Richard Zhu)
- Wait for i.MX95 PLL lock before enabling controller (Richard Zhu)
- Save/restore i.MX95 LUT for suspend/resume (Richard Zhu)
Mobiveil PCIe controller driver:
- Return bool (not int) for link-up check in
mobiveil_pab_ops.link_up() and layerscape-gen4, mobiveil (Hans
Zhang)
NVIDIA Tegra194 PCIe controller driver:
- Create debugfs directory for 'aspm_state_cnt' only when
CONFIG_PCIEASPM is enabled, since there are no other entries (Hans
Zhang)
Qualcomm PCIe controller driver:
- Add OF support for parsing DT 'eq-presets-<N>gts' property for lane
equalization presets (Krishna Chaitanya Chundru)

Pull tracing fixes from Steven Rostedt:
- Fix UAF in module unload in ftrace when there's a bug in the module
If a module is buggy and triggers ftrace_disable which is set when an
anomaly is detected, when it gets unloaded it doesn't free the hooks
into kallsyms, and when a kallsyms lookup is performed it may access
the mod->modname field and crash via UAF.
Fix this by still freeing the mod_maps that are attached to kallsyms
on module unload regardless if ftrace_disable is set or not.
- Do not bother allocating mod_maps for kallsyms if ftrace_disable is
set
- Remove unused trace events
When a trace event or tracepoint is created but not used, it still
creates the code and data structures needed for that trace event.
This just wastes memory.
Remove the trace events that are created but not used. This does not
remove trace events that are created but are not used due configs not
being set. That will be handled later. This only removes events that
have no user under any config.

Pull backlight updates from Lee Jones:
"Framebuffer Subsystem (fbdev):
- The display's blanking status is now tracked in 'struct fb_info'
- 'framebuffer_alloc()' initializes the blank state to FB_BLANK_UNBLANK
- 'register_framebuffer()' sets the state to 'FB_BLANK_POWERDOWN' if
an 'fb_blank' callback exists, ensuring 'FB_EVENT_BLANK' listeners
correctly see the display being turned on during the first modeset
- The 'FB_EVENT_BLANK' event data now includes both the new and the
old blank states
- 'fb_blank()' has been reworked to return early on errors, without
functional changes, in preparation for further state tracking
improvements
- Fbdev now calls dedicated functions in the backlight subsystems to
notify them of blank state changes, instead of relying on fbdev
event notifiers
- For LCDs, fbdev also calls a dedicated function to notify of mode
changes
- Removed the definitions for the unused fbdev event constants
'FB_EVENT_MODE_CHANGE' and 'FB_EVENT_BLANK' from the header file
Backlight Subsystem:
- Implemented fbdev blank state tracking using the (newly enhanced)
blank state information provided directly by 'FB_EVENT_BLANK'
- Removed internal blank state tracking fields ('fb_bl_on') from
'struct backlight_device'
- Moved the handling of blank-state updates into a separate internal
helper function, 'backlight_notify_blank()'
- Removed support for fbdev events and replaced it with a dedicated
function call interface ('backlight_notify_blank()' and
'backlight_notify_blank_all()') for display drivers to update
backlight status
LCD Subsystem:
- Moved the handling of display updates (blank events and mode
changes) from fbdev event notifiers to separate internal helper
functions ('lcd_notify_blank',
'lcd_notify_mode_change')
- Removed support for fbdev events and replaced it with dedicated
function call interfaces ('lcd_notify_blank_all()',
'lcd_notify_mode_change_all()')
- The LCD subsystem now maintains its own internal list of LCD
devices instead of relying on fbdev notifiers
LED Backlight Trigger:
- Moved the handling of blank-state updates into a separate internal
helper, 'ledtrig_backlight_notify_blank()'
- Removed support for fbdev events and replaced it with a dedicated
function call, 'ledtrig_backlight_blank()', for fbdev to notify
trigger of blank state changes
- The LED backlight trigger now maintains its own internal list of
triggers instead of relying on fbdev notifiers
Qualcomm WLED Backlight:
- Added a NULL check after 'devm_kasprintf()' in 'wled_configure()'
to prevent a potential NULL pointer dereference if memory

When the dax_fault_actor() helper was factored out, it removed the calls
to the dax_pmd_insert_mapping and dax_insert_mapping events but never
removed the events themselves. As each event created takes up memory
(roughly 5K each), this is a waste as it is never used.
Remove the unused dax_pmd_insert_mapping and dax_insert_mapping trace
events.
