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.

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.

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.

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
