[Why]
Memory allocation occurs within dml21_validate() for adding phantom planes.
May cause kernel to be tainted due to usage of FP Start.
[How]
Move FP start from dml21_validate to before mode programming/mode support.
Calculations requiring floating point are all done within mode programming
or mode support.

[WHY & HOW]
Remove the unnecessary DC_FP_START/DC_FP_END pair to reduce time in
preempt_disable. It also fixes "BUG: sleeping function called from

[Why]
FAMS2 expects vmin/vmax to be updated in the case when freesync is
off, but supported. But we only update it when freesync is enabled.
[How]
Change the vsync handler such that dc_stream_adjust_vmin_vmax() its called
irrespective of whether freesync is enabled. If freesync is supported,
then there is no harm in updating vmin/vmax registers.

[Why]
"BUG: sleeping function called from invalid context" error.
after:
"drm/amd/display: Protect FPU in dml2_validate()/dml21_validate()"
The populate_dml_plane_cfg_from_plane_state() uses the GFP_KERNEL flag
for memory allocation, which shouldn't be used in atomic contexts.
The allocation is needed only for using another helper function
get_scaler_data_for_plane().
[How]
Modify helpers to pass a pointer to scaler_data within existing context,
eliminating the need for dynamic memory allocation/deallocation
and copying.

Marek reported seeing a NULL pointer fault in the xenbus_thread
callstack:
BUG: kernel NULL pointer dereference, address: 0000000000000000
RIP: e030:__wake_up_common+0x4c/0x180
Call Trace:
<TASK>
__wake_up_common_lock+0x82/0xd0
process_msg+0x18e/0x2f0
xenbus_thread+0x165/0x1c0
process_msg+0x18e is req->cb(req). req->cb is set to xs_wake_up(), a
thin wrapper around wake_up(), or xenbus_dev_queue_reply(). It seems
like it was xs_wake_up() in this case.
It seems like req may have woken up the xs_wait_for_reply(), which
kfree()ed the req. When xenbus_thread resumes, it faults on the zero-ed
data.
Linux Device Drivers 2nd edition states:
"Normally, a wake_up call can cause an immediate reschedule to happen,
meaning that other processes might run before wake_up returns."
... which would match the behaviour observed.
Change to keeping two krefs on each request. One for the caller, and
one for xenbus_thread. Each will kref_put() when finished, and the last
will free it.
This use of kref matches the description in
Documentation/core-api/kref.rst

Make xenbus_init() allow a non-local xenstore for a PVH dom0 - it is
currently forced to XS_LOCAL. With Hyperlaunch booting dom0 and a
xenstore stubdom, dom0 can be handled as a regular XS_HVM following the
late init path.
Ideally we'd drop the use of xen_initial_domain() and just check for the
event channel instead. However, ARM has a xen,enhanced no-xenstore
mode, where the event channel and PFN would both be 0. Retain the
xen_initial_domain() check, and use that for an additional check when
the event channel is 0.
Check the full 64bit HVM_PARAM_STORE_EVTCHN value to catch the off
chance that high bits are set for the 32bit event channel.

Xen swiotlb support was missed when the patch set starting with
4ab5f8ec7d71 ("mm/slab: decouple ARCH_KMALLOC_MINALIGN from
ARCH_DMA_MINALIGN") was merged.
When running Xen on iMX8QXP, a SoC without IOMMU, the effect was that USB
transfers ended up corrupted when there was more than one URB inflight at
the same time.
Add a call to dma_kmalloc_needs_bounce() to make sure that allocations too
small for DMA get bounced via swiotlb.

The wlan_ctrl_by_user detection was introduced by commit a50bd128f28c
("asus-wmi: record wlan status while controlled by userapp").
Quoting from that commit's commit message:
"""
When you call WMIMethod(DSTS, 0x00010011) to get WLAN status, it may return
(1) 0x00050001 (On)
(2) 0x00050000 (Off)
(3) 0x00030001 (On)
(4) 0x00030000 (Off)
(5) 0x00000002 (Unknown)
(1), (2) means that the model has hardware GPIO for WLAN, you can call
WMIMethod(DEVS, 0x00010011, 1 or 0) to turn WLAN on/off.
(3), (4) means that the model doesn’t have hardware GPIO, you need to use
API or driver library to turn WLAN on/off, and call
WMIMethod(DEVS, 0x00010012, 1 or 0) to set WLAN LED status.
After you set WLAN LED status, you can see the WLAN status is changed with
WMIMethod(DSTS, 0x00010011). Because the status is recorded lastly
(ex: Windows), you can use it for synchronization.
(5) means that the model doesn’t have WLAN device.
WLAN is the ONLY special case with upper rule.
"""
The wlan_ctrl_by_user flag should be set on 0x0003000? ((3), (4) above)
return values, but the flag mistakenly also gets set on laptops with
0x0005000? ((1), (2)) return values. This is causing rfkill problems on
laptops where 0x0005000? is returned.
Fix the check to only set the wlan_ctrl_by_user flag for 0x0003000?
return values.

(GX4HRXL)
MECHREVO Wujie 14XA (GX4HRXL) wakes up immediately after s2idle entry.
This happens regardless of whether the laptop is plugged into AC power,
or whether any peripheral is plugged into the laptop.
Similar to commit a55bdad5dfd1 ("platform/x86/amd/pmc: Disable keyboard
wakeup on AMD Framework 13"), the MECHREVO Wujie 14XA wakes up almost
instantly after s2idle suspend entry (IRQ1 is the keyboard):
2025-04-18 17:23:57,588 DEBUG: PM: Triggering wakeup from IRQ 9
2025-04-18 17:23:57,588 DEBUG: PM: Triggering wakeup from IRQ 1
Add this model to the spurious_8042 quirk to workaround this.
This patch does not affect the wake-up function of the built-in keyboard.
Because the firmware of this machine adds an insurance for keyboard
wake-up events, as it always triggers an additional IRQ 9 to wake up the
system.

Change get_thinkpad_model_data() to check for additional vendor name
"NEC" in order to support NEC Lavie X1475JAS notebook (and perhaps
more).
The reason of this works with minimal changes is because NEC Lavie
X1475JAS is a Thinkpad inside. ACPI dumps reveals its OEM ID to be
"LENOVO", BIOS version "R2PET30W" matches typical Lenovo BIOS version,
the existence of HKEY of LEN0268, with DMI fw string is "R2PHT24W".
I compiled and tested with my own machine, attached the dmesg
below as proof of work:

With commit bcb5d6c76903 ("s390/pci: introduce lock to synchronize state
of zpci_dev's") the code to ignore power off of a PF that has child VFs
was changed from a direct return to a goto to the unlock and
pci_dev_put() section. The change however left the existing pci_dev_put()
untouched resulting in a doubple put. This can subsequently cause a use
after free if the struct pci_dev is released in an unexpected state.
Fix this by removing the extra pci_dev_put().

The original nvme subsystem design didn't have a CONNECTING state; the
state machine allowed transitions from RESETTING to LIVE directly.
With the introduction of nvme fabrics the CONNECTING state was
introduce. Over time the nvme-pci started to use the CONNECTING state as
well.
Eventually, a bug fix for the nvme-fc started to depend that the only
valid transition to LIVE was from CONNECTING. Though this change didn't
update the firmware update handler which was still depending on
RESETTING to LIVE transition.
The simplest way to address it for the time being is to switch into
CONNECTING state before going to LIVE state.

Use Device Serial Number instead of PCI bus/device/function for
the index of struct ice_adapter.
Functions on the same physical device should point to the very same
ice_adapter instance, but with two PFs, when at least one of them is
PCI-e passed-through to a VM, it is no longer the case - PFs will get
seemingly random PCI BDF values, and thus indices, what finally leds to
each of them being on their own instance of ice_adapter. That causes them
to don't attempt any synchronization of the PTP HW clock usage, or any
other future resources.
DSN works nicely in place of the index, as it is "immutable" in terms of
virtualization.
Fixes: 0e2bddf9e5f9 ("ice: add ice_adapter for shared data across PFs on the same NIC")

back the `uninlined_format_args` to `style` from `pedantic` (it was
there waiting for rust-analyzer suppotr), and thus we will start to see
lints like:
warning: variables can be used directly in the `format!` string

The vfio-pci huge_fault handler doesn't make any attempt to insert a
mapping containing the faulting address, it only inserts mappings if the
faulting address and resulting pfn are aligned. This works in a lot of
cases, particularly in conjunction with QEMU where DMA mappings linearly
fault the mmap. However, there are configurations where we don't get
that linear faulting and pages are faulted on-demand.
The scenario reported in the bug below is such a case, where the physical
address width of the CPU is greater than that of the IOMMU, resulting in a
VM where guest firmware has mapped device MMIO beyond the address width of
the IOMMU. In this configuration, the MMIO is faulted on demand and
tracing indicates that occasionally the faults generate a VM_FAULT_OOM.
Given the use case, this results in a "error: kvm run failed Bad address",
killing the VM.
The host is not under memory pressure in this test, therefore it's
suspected that VM_FAULT_OOM is actually the result of a NULL return from
__pte_offset_map_lock() in the get_locked_pte() path from insert_pfn().
This suggests a potential race inserting a pte concurrent to a pmd, and
maybe indicates some deficiency in the mm layer properly handling such a
case.
Nevertheless, Peter noted the inconsistency of vfio-pci's huge_fault
handler where our mapping granularity depends on the alignment of the
faulting address relative to the order rather than aligning the faulting
address to the order to more consistently insert huge mappings. This
change not only uses the page tables more consistently and efficiently, but
as any fault to an aligned page results in the same mapping, the race
condition suspected in the VM_FAULT_OOM is avoided.

If a driver is removed, the driver framework invokes the driver's
remove callback. A CAN driver's remove function calls
unregister_candev(), which calls net_device_ops::ndo_stop further down
in the call stack for interfaces which are in the "up" state.
The removal of the module causes a warning, as can_rx_offload_del()
deletes the NAPI, while it is still active, because the interface is
still up.
To fix the warning, first unregister the network interface, which
calls net_device_ops::ndo_stop, which disables the NAPI, and then call
can_rx_offload_del().

The TDC is currently hardcoded enabled. This means that even for lower
CAN-FD data bitrates (with a DBRP (data bitrate prescaler) > 2) a TDC
is configured. This leads to a bus-off condition.
ISO 11898-1 section 11.3.3 says "Transmitter delay compensation" (TDC)
is only applicable if DBRP is 1 or 2.
To fix the problem, switch the driver to use the TDC calculation
provided by the CAN driver framework (which respects ISO 11898-1
section 11.3.3). This has the positive side effect that userspace can
control TDC as needed.
Demonstration of the feature in action:

There has been some confusion about the MCP2518FD using a relative or
absolute TDCO due to the datasheet specifying a range of [-64,63]. I
have a custom board with a 40 MHz clock and an estimated loop delay of
100 to 216 ns. During testing at a data bit rate of 4 Mbit/s I found
that using can_get_relative_tdco() resulted in bus-off errors. The
final TDCO value was 1 which corresponds to a 10% SSP in an absolute
configuration. This behavior is expected if the TDCO value is really
absolute and not relative. Using priv->can.tdc.tdco instead results in
a final TDCO of 8, setting the SSP at exactly 80%. This configuration
works.
The automatic, manual, and off TDC modes were tested at speeds up to,
and including, 8 Mbit/s on real hardware and behave as expected.

Commit 4bc12818b363 ("virtio-net: disable delayed refill when pausing rx")
fixed a deadlock between reconfig paths and refill work trying to disable
the same NAPI instance. The refill work can't run in parallel with reconfig
because trying to double-disable a NAPI instance causes a stall under the
instance lock, which the reconfig path needs to re-enable the NAPI and
therefore unblock the stalled thread.
There are two cases where we re-enable refill too early. One is in the
virtnet_set_queues() handler. We call it when installing XDP:
virtnet_rx_pause_all(vi);
...
virtnet_napi_tx_disable(..);
...
virtnet_set_queues(..);
...
virtnet_rx_resume_all(..);
We want the work to be disabled until we call virtnet_rx_resume_all(),
but virtnet_set_queues() kicks it before NAPIs were re-enabled.
The other case is a more trivial case of mis-ordering in
__virtnet_rx_resume() found by code inspection.
Taking the spin lock in virtnet_set_queues() (requested during review)
may be unnecessary as we are under rtnl_lock and so are all paths writing

Pull SoC fixes from Arnd Bergmann:
"The main changes are once more for the NXP i.MX platform, addressing
multiple regressions in recent devicetree updates for the i.MX8MM and
i.MX6ULL SoCs, a PCIe fix for i.MX9 and a MAINTAINERS file update to
disambiguate NXP i.MX SoCs from Sony IMX image sensors.
The stm32 platform devicetree files get some compatibility fixes for
the interrupt controller node.
Another compatibility fix is done for the Arm Morello platform's cache
controller node.
The code changes are all for firmware drivers, fixing kernel-side bugs
on the Arm FF-A and SCMI drivers"

Event polling delay is set to 0 if there are any pending requests in
either rx or tx requests lists. Checking for pending requests does
not work well for "IN" transfers as the tty driver always queues
requests to the list and TRBs to the ring, preparing to receive data
from the host.
This causes unnecessary busylooping and cpu hogging.
Only set the event polling delay to 0 if there are pending tx "write"
transfers, or if it was less than 10ms since last active data transfer
in any direction.

VIA VL805 doesn't bother updating the EP Context cycle bit when the
endpoint halts. This is seen by patching xhci_move_dequeue_past_td()
to print the cycle bits of the EP Context and the TRB at hw_dequeue
and then disconnecting a flash drive while reading it. Actual cycle
state is random as expected, but the EP Context bit is always 1.
This means that the cycle state produced by this function is wrong
half the time, and then the endpoint stops working.
Work around it by looking at the cycle bit of TD's end_trb instead
of believing the Endpoint or Stream Context. Specifically:
- rename cycle_found to hw_dequeue_found to avoid confusion
- initialize new_cycle from td->end_trb instead of hw_dequeue
- switch new_cycle toggling to happen after end_trb is found
Now a workload which regularly stalls the device works normally for
a few hours and clearly demonstrates the HW bug - the EP Context bit
is not updated in a new cycle until Set TR Dequeue overwrites it:
[ +0,000298] sd 10:0:0:0: [sdc] Attached SCSI disk
[ +0,011758] cycle bits: TRB 1 EP Ctx 1
[ +5,947138] cycle bits: TRB 1 EP Ctx 1
[ +0,065731] cycle bits: TRB 0 EP Ctx 1
[ +0,064022] cycle bits: TRB 0 EP Ctx 0
[ +0,063297] cycle bits: TRB 0 EP Ctx 0
[ +0,069823] cycle bits: TRB 0 EP Ctx 0
[ +0,063390] cycle bits: TRB 1 EP Ctx 0
[ +0,063064] cycle bits: TRB 1 EP Ctx 1
[ +0,062293] cycle bits: TRB 1 EP Ctx 1
[ +0,066087] cycle bits: TRB 0 EP Ctx 1
[ +0,063636] cycle bits: TRB 0 EP Ctx 0
[ +0,066360] cycle bits: TRB 0 EP Ctx 0
Also tested on the buggy ASM1042 which moves EP Context dequeue to
the next TRB after errors, one problem case addressed by the rework
that implemented this loop. In this case hw_dequeue can be enqueue,
so simply picking the cycle bit of TRB at hw_dequeue wouldn't work.
Commit 5255660b208a ("xhci: add quirk for host controllers that
don't update endpoint DCS") tried to solve the stale cycle problem,
but it was more complex and got reverted due to a reported issue.

After commit 653d7825c149 ("dcssblk: mark DAX broken, remove FS_DAX_LIMITED
support") moved the "select DAX" from config DCSSBLK to the new config
DCSSBLK_DAX, randconfig tests could result in build errors like this:
s390-linux-ld: drivers/s390/block/dcssblk.o: in function `dcssblk_shared_store':
drivers/s390/block/dcssblk.c:417: undefined reference to `kill_dax'
s390-linux-ld: drivers/s390/block/dcssblk.c:418: undefined reference to `put_dax'
This is because it's now possible to have CONFIG_DCSSBLK=y, but CONFIG_DAX=m.
Fix this by adding "depends on DAX || DAX=n" to config DCSSBLK, to make it
explicit that we want either no DAX, or the same "y/m" for both config DAX
and DCSSBLK, similar to config BLK_DEV_DM.
This also requires removing the "select DAX" from config DCSSBLK_DAX, or
else there would be a recursive dependency detected. DCSSBLK_DAX is marked
as BROKEN at the moment, and won't work well with DAX anyway, so it doesn't
really matter if it is selected.

On x86 during boot, clockevent_i8253_disable() can be invoked via
x86_late_time_init -> hpet_time_init() -> pit_timer_init() which happens
with enabled interrupts.
If some of the old i8253 hardware is actually used then lockdep will notice
that i8253_lock is used in hard interrupt context. This causes lockdep to
complain because it observed the lock being acquired with interrupts
enabled and in hard interrupt context.
Make clockevent_i8253_disable() acquire the lock with
raw_spinlock_irqsave() to cure this.

Some file systems do not support read_iter/write_iter, such as selinuxfs
in this issue.
So before calling them, first confirm that the interface is supported and
then call it.
It is releavant in that vfs_iter_read/write have the check, and removal
of their used caused szybot to be able to hit this issue.

As seen in some recent failures, SLPC num_waiters value is < 0.
This happens because the inc/dec are not balanced. We should skip
decrement for the same conditions as the increment. Currently, we
do that for power saving profile mode. This patch also ensures that
num_waiters is incremented in the case min_softlimit is at boost
freq. It ensures that we don't reduce the frequency while this request
is in flight.
