This patch is for for-next branch.
The selfIDComplete event occurs in the bus managed by one of 1394 OHCI
controller in Linux system, while the existing tracepoints events has
the lack of data about it to distinguish the issued hardware from the
others.
This commit adds card_index member into event structure to store the index
of host controller in use, and prints it.

In the protocol of IEEE 1394, phy configuration packet is broadcasted to
the bus to configure all PHYs residing on the bus. It includes two
purposes; selecting root node and optimizing gap count.
This commit adds some helper function to serialize/deserialize the
content of phy configuration packet, as well as some KUnit tests for it.

It is helpful to trace the content of self ID sequence when the core
function building bus topology.
This commit adds a tracepoints event fot the purpose. It seems not to
achieve printing variable length of array in print time without any
storage, thus the structure of event includes a superfluous array to store
the state of port. Additionally, there is no helper function to print
symbol array, thus the state of port is printed as raw value.

When the state of bus reset finishes, 1394 OHCI driver constructs self ID
sequences, then it calls fw_core_handle_bus_reset() in core function. The
core function enumerates the self ID sequences to build bus topology.
This commit adds a structure and some helper functions for the enumeration,
and adds a KUnit test suite to ensure its expected behaviour.

One patch from John David Anglin which reworks the parisc cache flushing
routines with the aim to fix the random segmentation faults on machines with
PA8800 and PA8900 processors. We have faced those segfaults since many years,
but with this patch no single segfault could be triggered any longer. The
patch was tested by 3 people on 5 different machines with various stable
kernels (6.6, 6.8 and 6.9).

Pull parisc fix from Helge Deller:
"On parisc we have suffered since years from random segfaults which
seem to have been triggered due to cache inconsistencies. Those
segfaults happened more often on machines with PA8800 and PA8900 CPUs,
which have much bigger caches than the earlier machines.
Dave Anglin has worked over the last few weeks to fix this bug. His
patch has been successfully tested by various people on various
machines and with various kernels (6.6, 6.8 and 6.9), and the debian
buildd servers haven't shown a single random segfault with this patch.
Since the cache handling has been reworked, the patch is slightly
bigger than I would like in this stage, but the greatly improved
stability IMHO justifies the inclusion now"

Commit 66601a29bb ("leds: class: If no default trigger is given, make
hw_control trigger the default trigger") causes ledtrig-netdev to get
set as default trigger on various network LEDs.
This causes users to hit a pre-existing AB-BA deadlock issue in
ledtrig-netdev between the LED-trigger locks and the rtnl mutex,
resulting in hung tasks in kernels >= 6.9.
Solving the deadlock is non trivial, so for now revert the change to
set the hw_control trigger as default trigger, so that ledtrig-netdev
no longer gets activated automatically for various network LEDs.
The netdev trigger is not needed because the network LEDs are usually under
hw-control and the netdev trigger tries to leave things that way so setting
it as the active trigger for the LED class device is a no-op.
Fixes: 66601a29bb ("leds: class: If no default trigger is given, make hw_control trigger the default trigger")

Merge tag 'i2c-host-fixes-6.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-current
Two fixes from Jean aim to correctly report i2c functionality,
specifically ensuring that I2C_FUNC_SLAVE is reported when a
device operates solely as a slave interface.
The currently used normalized address format is not applicable to all
MI300 systems. This leads to incorrect results during address
translation.
Drop the fixed layout and construct the normalized address from system
settings.

- Fix long standing lockdep issue of using remap_pfn_range() from
the vfio-pci fault handler for mapping device MMIO. Commit
ba168b52bf ("mm: use rwsem assertion macros for mmap_lock") now
exposes this as a warning forcing this to be addressed.
remap_pfn_range() was used here to efficiently map the entire vma,
but it really never should have been used in the fault handler and
doesn't handle concurrency, which introduced complex locking. We
also needed to track vmas mapping the device memory in order to zap
those vmas when the memory is disabled resulting in a vma list.
Instead of all that mess, setup an address space on the device fd
such that we can use unmap_mapping_range() for zapping to avoid
the tracking overhead and use the standard vmf_insert_pfn() to
insert mappings on fault. For now we'll iterate the vma and
opportunistically try to insert mappings for the entire vma. This
aligns with typical use cases, but hopefully in the future we can
drop the iterative approach and make use of huge_fault instead,
once vmf_insert_pfn{pud,pmd}() learn to handle pfnmaps.
