Pull tracing fixes from Steven Rostedt:
- Fix another kerneldoc warning
- Fix eventfs files to inherit the ownership of its parent directory.
The dynamic creation of dentries in eventfs did not take into account
if the tracefs file system was mounted with a gid/uid, and would
still default to the gid/uid of root. This is a regression.
- Fix warning when synthetic event testing is enabled along with
startup event tracing testing is enabled

nvme_init_ctrl() resets numa_node to NUMA_NO_NODE, so be sure to set the

RISC-V Devicetrees for v6.8
StarFive:
Key peripheral support for the jh7100 that depended on the non-standard
non-coherent DMA operations, namely mmc, sdcard and sdio wifi. This
platform has long been supported out of tree by Emil and Ubuntu etc ship
images for it, so having mainline support for a wider range of
peripherals (at last) is great.
Microchip:
The flash used by Auto Update support and the corresponding QSPI
controller are added. On publicly available Icicle kits this flash is
not usable (engineering sample silicon issues) but in the future Icicle
kits will be available that have production silicon.
T-Head:
Jisheng is busy with RL this cycle and hence T-Head appears here. The
Lichee Pi and BeagleV both grow eMMC and uSD support.
Sopgho:
Support for the Huashan Pi and the cv1812h SoC it uses. The cv1812h is
almost identical to the existing cv1800b SoC. These SoCs are intended
for use in IP camera type systems but also appear on SBCs, with the last
digit denoting the amount integrated DDR3 the device has. The difference
between the cv1812h and the existing cv180x devices appears to be the
addition of video output interfaces.

As part of the FW definitions, we declare each blob as required via the
MODULE_FIRMWARE() macro. This causes the initramfs update (or equivalent
process) to look for the blobs on disk when the kernel is installed;
therefore, we need to make sure that all FWs we define are available in
linux-firmware.
We currently don't plan to push the PVC blob to linux-firmware, while the
LNL one will only be pushed once we have machines in CI to test it, so we
need to remove them from the list for now.

Ideally this header could be included without the CONFIG_FAULT_INJECTION
and it would take care itself for the includes it needs.
So, let's temporary workaround this by moving this below and including
only when CONFIG_FAULT_INJECTION is selected to avoid build breakages.
Another solution would be us including the linux/types.h as well, but
this creates unnecessary cases.

The tail of the provided ring buffer is shared between the kernel and
the application, but the head is private to the kernel as the
application doesn't need to see it. However, this also prevents the
application from knowing how many buffers the kernel has consumed.
Usually this is fine, as the information is inherently racy in that
the kernel could be consuming buffers continually, but for cleanup
purposes it may be relevant to know how many buffers are still left
in the ring.
Add IORING_REGISTER_PBUF_STATUS which will return status for a given
provided buffer ring. Right now it just returns the head, but space
is reserved for more information later in, if needed.

In order to make proper use the uAPI, a prerequisite is to understand
some key concepts about the discrete GPU devices which are supported
by the Xe driver. For example, some structs defined in the uAPI are an
abstraction of a hardware component with a specific role.
This diagram helps to build a mental representation of a device how it
is seen by the Xe driver. As written in the documentation, it does not
intend to be a literal representation of an existing device. A lot
more information could be added but the intention for the overview is
to keep it simple, and go into detail as needed in other sections.

The uAPI should stay generic in regarding to the bitmask. It is
the userspace responsibility to check for the type/class of the
memory, without any assumption.
Also add comments inside the code to explain how it is actually
constructed so we don't accidentally change the assignment of
the instance and the masks.
No functional change in this patch. It only explains and document
the memory_region masks. A further follow-up work with the
organization of all memory regions around struct xe_mem_regions
is desired, but not part of this patch.

No functional change in this patch.
Let's ensure all of our structs are documented and with a certain
standard. Also, let's have an overview and list of IOCTLs as the
very beginning of the generated HTML doc.

This patch doesn't modify any text or uapi entries themselves.
It only move things up and down aiming a better organization of the uAPI.
While fixing the documentation I noticed that query_engine_cs_cycles
was in the middle of the memory_region info. Then I noticed more
mismatches on the order when compared to the order of the IOCTL
and QUERY entries declaration. So this patch aims to bring some
order to the uAPI so it gets easier to read and the documentation
generated in the end is able to tell a consistent story.
Overall order:
1. IOCTL definition
2. Extension definition and helper structs
3. IOCTL's Query structs in the order of the Query's entries.
4. The rest of IOCTL structs in the order of IOCTL declaration.
5. uEvents

As there is no direct way to make comments of constants directly

Remove concept of async vs sync VM bind queues, rather make all binds
async.
The following bits have dropped from the uAPI:
DRM_XE_ENGINE_CLASS_VM_BIND_ASYNC
DRM_XE_ENGINE_CLASS_VM_BIND_SYNC
DRM_XE_VM_CREATE_FLAG_ASYNC_DEFAULT
DRM_XE_VM_BIND_FLAG_ASYNC
To implement sync binds the UMD is expected to use the out-fence
interface.

remove the num_engines/instances members from drm_xe_wait_user_fence
structure and add a exec_queue_id member
Right now this is only checking if the engine list is sane and nothing
else. In the end every operation with this IOCTL is a soft check.
So, let's formalize that and only use this IOCTL to wait on the fence.
exec_queue_id member will help to user space to get proper error code
from kernel while in exec_queue reset
