6e6d3c6f0e dmaengine: stm32: Don't use %pK through printk
In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d24 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping locks in atomic contexts.

Switch to the regular pointer formatting which is safer and
easier to reason about.

e19bdbaa31 dmaengine: stm32-dma: configure next sg only if there are more than 2 sgs
DMA operates in Double Buffer Mode (DBM) when the transfer is cyclic and
there are at least two periods.
When DBM is enabled, the DMA toggles between two memory targets (SxM0AR and
SxM1AR), indicated by the SxSCR.CT bit (Current Target).
There is no need to update the next memory address if two periods are
configured, as SxM0AR and SxM1AR are already properly set up before the
transfer begins in the stm32_dma_start_transfer() function.
This avoids unnecessary updates to SxM0AR/SxM1AR, thereby preventing
potential Transfer Errors. Specifically, when the channel is enabled,
SxM0AR and SxM1AR can only be written if SxSCR.CT=1 and SxSCR.CT=0,
respectively. Otherwise, a Transfer Error interrupt is triggered, and the
stream is automatically disabled.

5f295519b4 smp: Improve locality in smp_call_function_any()
smp_call_function_any() tries to make a local call as it's the cheapest
option, or switches to a CPU in the same node. If it's not possible, the
algorithm gives up and searches for any CPU, in a numerical order.

Instead, it can search for the best CPU based on NUMA locality, including
the 2nd nearest hop (a set of equidistant nodes), and higher.

sched_numa_find_nth_cpu() does exactly that, and also helps to drop most
of the housekeeping code.

This mirrors the existing Open Firmware (OF) support (`of_id_table`) and

a6f494becf PCI/AER: Add message when AER_MAX_MULTI_ERR_DEVICES limit is hit
When a PCIe device detects an error, it logs the error locally and issues
an error Message routed to the Root Complex (PCIe r6.0, sec 6.2.5). If the
Root Port or RCEC supports AER and Linux has enabled the AER interrupt,
aer_isr() traverses the relevant devices and adds those with AER errors
logged to the aer_err_info.dev[] array for error logging and recovery.

If aer_isr() finds more than AER_MAX_MULTI_ERR_DEVICES devices with AER
errors logged, it silently ignores them, and those extra devices are not
included in the recovery flow.

Emit an error message if we find more than AER_MAX_MULTI_ERR_DEVICES
devices with AER errors logged.

a42939ee86 drm/xe: Remove xe_uc_fini_hw
xe_uc_init_hw() is called multiple times from xe_gt.c,
and that makes the name xe_uc_fini_hw(), called for a different
reason in xe_guc.c confusing.

Remove it and inline the xe_uc_sanitize_reset into xe_guc.c directly.

Now that we added the separate step of initialising GUC in

init, and the rest after allocations are allowed.

Clarify that the functions are the part of gt_init() that are called

works after discovering and initialisation of force_wake on all engines,
that's why the split is needed in the first place.

Everything in vf_guc_init should be done as early as possible, otherwise
VRAM probing becomes impossible.

Also move xe_gt_mmio_init to the end of xe_gt_init_early(), cleaning up

ef4af870be ACPICA: Decrease AcpiExTracePoint verbosity
Early in kernel boot pointers can't be used and so %p shows up
incorrectly:

```
extrace-0138 ex_trace_point        : Method Begin [0x(____ptrval____):\M460] execution.
```

Later in the boot %p works, but it's not really actually useful when
the pathname can resolve properly.

Adjust the debug print so that if the Pathname resolves that the pointer
isn't also printed:

```
extrace-0138 ex_trace_point        : Method Begin [\M460] execution.
```
