Notifications may now be linked and thus a single tw can post multiple
CQEs, it's not safe to use LAZY_WAKE with them. Disable LAZY_WAKE for
now, if that'd prove to be a problem we can count them and pass the
expected number of CQEs into __io_req_task_work_add().

SEND[MSG]_ZC produces multiple CQEs via notifications, LAZY_WAKE doesn't
handle it and so disable LAZY_WAKE for sendzc polling. It should be
fine, sends are not likely to be polled in the first place.

As described in the added code comment, a reference to .exit.text is ok
for drivers registered via module_platform_driver_probe(). Make this
explicit to prevent the following section mismatch warning
WARNING: modpost: drivers/input/mouse/amimouse: section mismatch in reference: amimouse_driver+0x8 (section: .data) -> amimouse_remove (section: .exit.text)

Enable ufs & ufs phy nodes for Oriole. Also define the ufs regulator node.
ufs regulator is a stub until full s2mpg11 slave pmic support is added.
The gpio defined is for the BOOTLD0 (gs101) signal connected to
UFS_EN(s2mpg11) gpio enabled voltage rail for UFS.

typec_register_partner() does not guarantee partner registration
to always succeed. In the event of failure, port->partner is set
to the error value or NULL. Given that port->partner validity is
not checked, this results in the following crash:

Before sending Enter Mode for an Alt Mode, there is a gap between Discover
Modes and the Alt Mode driver queueing the Enter Mode VDM for the port
partner to send a message to the port.
If this message results in unregistering Alt Modes such as in a DR_SWAP,
then the following deadlock can occur with respect to the DisplayPort Alt
Mode driver:
1. The DR_SWAP state holds port->lock. Unregistering the Alt Mode driver
results in a cancel_work_sync() that waits for the current dp_altmode_work
to finish.
2. dp_altmode_work makes a call to tcpm_altmode_enter. The deadlock occurs
because tcpm_queue_vdm_unlock attempts to hold port->lock.
Before attempting to grab the lock, ensure that the port is in a state
vdm_run_state_machine can run in. Alt Mode unregistration will not occur
in these states.

When a Fast Role Swap control message attempt results in a transition
to ERROR_RECOVERY, the TCPC can still queue a TCPM_SOURCING_VBUS event.
If the event is queued but processed after the tcpm_reset_port() call
in the PORT_RESET state, then the following occurs:
1. tcpm_reset_port() calls tcpm_init_vbus() to reset the vbus sourcing and
sinking state
2. tcpm_pd_event_handler() turns VBUS on before the port is in the default
state.
3. The port resolves as a sink. In the SNK_DISCOVERY state,
tcpm_set_charge() cannot set vbus to charge.
Clear pd events within PORT_RESET to get rid of non-applicable events.

Add fortify tests for memcpy() and memmove(). This can use a similar
method to the fortify_panic() replacement, only we can do it for what
was the WARN_ONCE(), which can be redefined.
Since this is primarily testing the fortify behaviors of the memcpy()
and memmove() defenses, the tests for memcpy() and memmove() are
identical.

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
data_page wants to be NUL-terminated and NUL-padded, use strscpy_pad to
provide both of these. data_page no longer awkwardly relies on
init_mount to perform its NUL-termination, although that sanity check is
left unchanged.

Correctly set the length of the drm_event to the size of the structure
that's actually used.
The length of the drm_event was set to the parent structure instead of
to the drm_vmw_event_fence which is supposed to be read. drm_read
uses the length parameter to copy the event to the user space thus
resuling in oob reads.

Currently we allocate all 3 levels of radix3 page tables using
nvkm_gsp_mem_ctor(), which uses dma_alloc_coherent() for allocating all of
the relevant memory. This can end up failing in scenarios where the system
has very high memory fragmentation, and we can't find enough contiguous
memory to allocate level 2 of the page table.
Currently, this can result in runtime PM issues on systems where memory
fragmentation is high - as we'll fail to allocate the page table for our
suspend/resume buffer:

Luckily, we don't actually need to allocate coherent memory for the page
table thanks to being able to pass the GPU a radix3 page table for
suspend/resume data. So, let's rewrite nvkm_gsp_radix3_sg() to use the sg
allocator for level 2. We continue using coherent allocations for lvl0 and
1, since they only take a single page.

We hit this when trying to initialize firmware of type
NVKM_FIRMWARE_IMG_DMA because we allocate our memory with
dma_alloc_coherent, and DMA allocations can't be turned back into memory
pages - which a scatterlist needs in order to map them.
So, fix this by allocating the memory with vmalloc instead().

Unfortunately both Lenovo Legion Pro 7 16ARX8H and Legion 7i 16IAX7
got the very same PCI SSID while the hardware implementations are
completely different (the former is with TI TAS2781 codec while the
latter is with Cirrus CS35L41 codec). The former model got broken by
the recent fix for the latter model.
For addressing the regression, check the codec SSID and apply the
proper quirk for each model now.

A virtual SuperSpeed device in the FreeBSD BVCP package
(https://bhyve.npulse.net/) presents an invalid ep0 maxpacket size of 256.
It stopped working with Linux following a recent commit because now we
check these sizes more carefully than before.
Fix this regression by using the bMaxpacketSize0 value in the device
descriptor for SuperSpeed or faster devices, even if it is invalid. This
is a very simple-minded change; we might want to check more carefully for
values that actually make some sense (for instance, no smaller than 64).

Testing ohci functionality with qemu's pci-ohci emulation often results
in ohci interface stalls, resulting in hung task timeouts.
The problem is caused by lost interrupts between the emulation and the
Linux kernel code. Additional interrupts raised while the ohci interrupt
handler in Linux is running and before the handler clears the interrupt
status are not handled. The fix for a similar problem in ehci suggests
that the problem is likely caused by edge-triggered MSI interrupts. See
commit 0b60557230ad ("usb: ehci: Prevent missed ehci interrupts with
edge-triggered MSI") for details.
Ensure that the ohci interrupt code handles all pending interrupts before
returning to solve the problem.

Merge series from Jerome Brunet <jbrunet@baylibre.com>:
This patchset fixes 2 problems on TDM which both find a solution
by properly implementing the .trigger() callback for the TDM backend.
ATM, enabling the TDM formatters is done by the .prepare() callback
because handling the formatter is slow due to necessary calls to CCF.
The first problem affects the TDMIN. Because .prepare() is called on DPCM
backend first, the formatter are started before the FIFOs and this may
cause a random channel shifts if the TDMIN use multiple lanes with more
than 2 slots per lanes. Using trigger() allows to set the FE/BE order,
solving the problem.
There has already been an attempt to fix this 3y ago [1] and reverted [2]
It triggered a 'sleep in irq' error on the period IRQ. The solution is
to just use the bottom half of threaded IRQ. This is patch #1. Patch #2
and #3 remain mostly the same as 3y ago.
For TDMOUT, the problem is on pause. ATM pause only stops the FIFO and
the TDMOUT just starves. When it does, it will actually repeat the last
sample continuously. Depending on the platform, if there is no high-pass
filter on the analog path, this may translate to a constant position of
the speaker membrane. There is no audible glitch but it may damage the
speaker coil.
Properly stopping the TDMOUT in pause solves the problem. There is
behaviour change associated with that fix. Clocks used to be continuous
on pause because of the problem above. They will now be gated on pause by
default, as they should. The last change introduce the proper support for
continuous clocks, if needed.

[BUG]
When running generic/287, the following file extent items can be
generated:
item 16 key (258 EXTENT_DATA 2682880) itemoff 15305 itemsize 53
generation 9 type 1 (regular)
extent data disk byte 1378414592 nr 462848
extent data offset 0 nr 462848 ram 2097152
extent compression 0 (none)
Note that file extent item is not a compressed one, but its ram_bytes is
way larger than its disk_num_bytes.
According to btrfs on-disk scheme, ram_bytes should match disk_num_bytes
if it's not a compressed one.
[CAUSE]
Since commit b73a6fd1b1ef ("btrfs: split partial dio bios before
submit"), for partial dio writes, we would split the ordered extent.
However the function btrfs_split_ordered_extent() doesn't update the
ram_bytes even it has already shrunk the disk_num_bytes.
Originally the function btrfs_split_ordered_extent() is only introduced
for zoned devices in commit d22002fd37bd ("btrfs: zoned: split ordered
extent when bio is sent"), but later commit b73a6fd1b1ef ("btrfs: split
partial dio bios before submit") makes non-zoned btrfs affected.
Thankfully for un-compressed file extent, we do not really utilize the
ram_bytes member, thus it won't cause any real problem.
[FIX]
Also update btrfs_ordered_extent::ram_bytes inside
btrfs_split_ordered_extent().
Fixes: d22002fd37bd ("btrfs: zoned: split ordered extent when bio is sent")

With 'iommu=off' on the kernel command line and x2APIC enabled by the BIOS
the code which disables the x2APIC triggers an unchecked MSR access error:
RDMSR from 0x802 at rIP: 0xffffffff94079992 (native_apic_msr_read+0x12/0x50)
This is happens because default_acpi_madt_oem_check() selects an x2APIC
driver before the x2APIC is disabled.
When the x2APIC is disabled because interrupt remapping cannot be enabled
due to 'iommu=off' on the command line, x2apic_disable() invokes
apic_set_fixmap() which in turn tries to read the APIC ID. This triggers
the MSR warning because x2APIC is disabled, but the APIC driver is still
x2APIC based.
Prevent that by adding an argument to apic_set_fixmap() which makes the
APIC ID read out conditional and set it to false from the x2APIC disable
path. That's correct as the APIC ID has already been read out during early
discovery.

Commit 47ea0ddb1f56 ("platform/chrome: cros_ec_lpc: Separate host
command and irq disable") re-ordered the resume sequence. Before that
change, cros_ec resume sequence is:
1) Enable IRQ
2) Send resume event
3) Handle events during suspend
After commit 47ea0ddb1f56 ("platform/chrome: cros_ec_lpc: Separate host
command and irq disable"), cros_ec resume sequence is:
1) Enable IRQ
2) Handle events during suspend
3) Send resume event.
This re-ordering leads to delayed handling of any events queued between
items 2) and 3) with the updated sequence. Also in certain platforms, EC
skips triggering interrupt for certain events eg. mkbp events until the
resume event is received. Such events are stuck in the host event queue
indefinitely. This change puts back the original order to avoid any
delay in handling the pending events.

Pull workqueue fixes from Tejun Heo:
"Two doc update patches and the following three fixes:
- On single node systems, the default pool is used but the
node_nr_active for the default pool was set to min_active. This
effectively limited the max concurrency of unbound pools on single
node systems to 8 causing performance regressions on some
workloads. Fixed by setting the default pool's node_nr_active to
max_active.
- wq_update_node_max_active() could trigger divide-by-zero if the
intersection between the allowed CPUs for an unbound workqueue and
online CPUs becomes empty.
- When kick_pool() was trying to repatriate a worker to a CPU in its
pod by setting task->wake_cpu, it didn't consider whether the CPU
being selected is online or not which obviously can lead to
subobtimal behaviors. On s390, this triggered a crash in arch code.
The workqueue patch removes the gross misbehavior but doesn't fix
the crash completely as there's a race window in which CPUs can go
down after wake_cpu is set. Need to decide whether the fix should
be on the core or arch side"

Arm FF-A updates for v6.10
1. Support for handling notification pending interrupt(NPI)
The FF-A uses the notification pending interrupt to inform the receiver
that it has a pending notification. This is a virtual interrupt and is
used by the following type of receivers:
- A guest/VM running under a hypervisor(normal world usecase)
- An S-EL1 SP running under a S-EL2 SPMC(secure world only usecase)
Also, when the FF-A driver is running inside a guest VM under an
hypervisor, the driver/guest VM doesn't have the permission/capability
to request the creation of notification bitmaps. For a VM, the hypervisor
reserves memory for its VM and hypervisor framework notification bitmaps
and the SPMC reserves memory for its SP and SPMC framework notification
bitmaps before the hypervisor initializes it.
These changes include skipping of creation of notification bitmaps, some
refactoring around schedule receiver interrupt(SRI) handling and addition
of support for NPI.
2. Support for FF-A indirect messaging
The FFA_MSG_SEND2 can be used to transmit a partition message from
the Tx buffer of the sender(the driver in this case) endpoint to the Rx
buffer of the receiver endpoint and inform the scheduler that the
receiver endpoint must be run.
Apart from these two main features, there is an optimisation to avoid
queuing of a work when already running on the worker queue.

Arm SCMI updates for v6.10
1. Basic support for SCMI v3.2 pincontrol protocol
SCMI v3.2 introduces pincontrol protocol which is intended for
controlling pins and their configuration. The pin control protocol
provides commands to:
- List the pins, groups of pins, available functions, and their
association with each other.
- Set the parameter configuration and multiplexing of the pins or
groups of pins
- Optionally request exclusive access to a pin or group of pins.
- Optionally configure the permissions of an agent to access a pin
or group of pins.
These changes adds basic support for the same in the SCMI core layer
and an implementation of the generic scmi-pinctrl driver with associated
DT bindings.
2. Framework support for multiple vendors custom protocols
With the fixed space for vendor protocols, the possibility of having
multiple vendors implementing distinct SCMI vendor protocols with
the same overlapping protocol number is very high and with the need
to support them all in a single kernel image or a module is also high.
In order to implement the same we assume:
- vendor protocols has to be tagged at build time with a vendor_id
- vendor protocols could also optionally be tagged at build time with
sub_vendor_id and implementation version
At the initialisation all the built vendor protocols are registered
with the SCMI core using a key derived from the above tags
3. Logging and tracing improvements
This includes using dev_err_probe() to bail out from probe, adding
message dump traces for bad and unexpected replies and widening of
the tag buffer in trace_scmi_dump_msg to allow diverse tag names
4. Miscellaneous updates or improvements
This includes adding the accessor function get_max_msg_size() used
in pinctl protocol, updation of dt-bindings examples for protocol@13
to promote new bindings and simplification of scmi_devm_notifier_unregister

TEE driver for Trusted Services
This introduces a TEE driver for Trusted Services [1].
Trusted Services is a TrustedFirmware.org project that provides a
framework for developing and deploying device Root of Trust services in
FF-A [2] Secure Partitions. The project hosts the reference
implementation of Arm Platform Security Architecture [3] for Arm
A-profile devices.
The FF-A Secure Partitions are accessible through the FF-A driver in
Linux. However, the FF-A driver doesn't have a user space interface so
user space clients currently cannot access Trusted Services. The goal of
this TEE driver is to bridge this gap and make Trusted Services
functionality accessible from user space.
