The qrtr protocol core logic and the qrtr nameservice are combined into
a single module. Neither the core logic or nameservice provide much
functionality by themselves; combining the two into a single module also
prevents any possible issues that may stem from client modules loading
inbetween qrtr and the ns.
Creating a socket takes two references to the module that owns the
socket protocol. Since the ns needs to create the control socket, this
creates a scenario where there are always two references to the qrtr
module. This prevents the execution of 'rmmod' for qrtr.
To resolve this, forcefully put the module refcount for the socket
opened by the nameservice.

We observe intermittent ping failures from the access point (AP) to
station (STA) in any mode (AP-STA or Mesh) configured. Specifically,
the transmission completion status is not received at tx completion
ring id 4 (WBM2SW ring4) for the packets transmitted via TCL DATA
ring id 3. This prevents freeing up tx descriptors and leads
to buffer exhaustion.
Currently, during initialization of the WBM2SW ring, we are directly
mapping the ring number to the ring mask to obtain the ring mask
group index. This approach is causing setup failures for WBM2SW
ring 4. Similarly, during runtime, when receiving incoming
transmission completion status, the validation of the ring number by
mapping the interrupted ring mask. This is resulting in
validation failure. Thereby preventing entry into the completion
handler ath12k_dp_tx_completion_handler().
The existing design assumed that the ring numbers would always be
sequential and could be directly mapped with the ring mask. However,
this assumption does not hold true for WBM2SW ring 4. Therefore,
modify the design such that, instead of mapping the ring number,
the ring ID is mapped with the ring mask.
According to this design:
1. During initialization of the WBM2SW ring, mapping the ring ID
to the ring mask will ensure obtaining the correct ring mask group
ID.
2. During runtime, validating the interrupted ring mask group ID
within the transmission completion group is sufficient. This
approach allows the ring ID to be derived from the interrupted ring
mask and enables entry into the completion handler.

When debugging GPU hangs Mesa developers are finding it useful to replay
the captured error state against the simulator. But due various simulator
limitations which prevent replicating all hangs, one step further is being
able to replay against a real GPU.
This is almost doable today with the missing part being able to upload the
captured context image into the driver state prior to executing the
uploaded hanging batch and all the buffers.
To enable this last part we add a new context parameter called
I915_CONTEXT_PARAM_CONTEXT_IMAGE. It follows the existing SSEU
configuration pattern of being able to select which context to apply
against, paired with the actual image and its size.
Since this is adding a new concept of debug only uapi, we hide it behind
a new kconfig option and also require activation with a module parameter.
Together with a warning banner printed at driver load, all those combined
should be sufficient to guard against inadvertently enabling the feature.
In terms of implementation we allow the legacy context set param to be
used since that removes the need to record the per context data in the
proto context, while still allowing flexibility of specifying context
images for any context.
Mesa MR using the uapi can be seen at:
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/27594
v2:
* Fix whitespace alignment as per checkpatch.
* Added warning on userspace misuse.
* Rebase for extracting ce->default_state shadowing.
v3:
* Rebase for I915_CONTEXT_PARAM_LOW_LATENCY.

Allocate cleared blocks in the bias range when the DRM
buddy's clear avail is zero. This will validate the bias
range allocation in scenarios like system boot when no
cleared blocks are available and exercise the fallback
path too. The resulting blocks should always be dirty.

- move the size to the variable declaration section.
- move the mm.clear_avail init to allocator init.

Problem statement: During the system boot time, an application request
for the bulk volume of cleared range bias memory when the clear_avail
is zero, we dont fallback into normal allocation method as we had an
unnecessary clear_avail check which prevents the fallback method leads
to fb allocation failure following system goes into unresponsive state.
Solution: Remove the unnecessary clear_avail check in the range bias
allocation function.

During a cgroup_rstat_flush() call, the lowest level of nodes are flushed
first before their parents. Since commit 3b8cc62987 ("blk-cgroup:
Optimize blkcg_rstat_flush()"), iostat propagation was still done to
the parent. Grandparent, however, may not get the iostat update if the
parent has no blkg_iostat_set queued in its lhead lockless list.
Fix this iostat propagation problem by queuing the parent's global
blkg->iostat into one of its percpu lockless lists to make sure that
the delta will always be propagated up to the grandparent and so on
toward the root blkcg.
Note that successive calls to __blkcg_rstat_flush() are serialized by
the cgroup_rstat_lock. So no special barrier is used in the reading
and writing of blkg->iostat.lqueued.

__blkcg_rstat_flush() can be run anytime, especially when blk_cgroup_bio_start
is being executed.
If WRITE of `->lqueued` is re-ordered with READ of 'bisc->lnode.next' in
the loop of __blkcg_rstat_flush(), `next_bisc` can be assigned with one
stat instance being added in blk_cgroup_bio_start(), then the local
list in __blkcg_rstat_flush() could be corrupted.
Fix the issue by adding one barrier.

can't reset the stat instance by memset(), otherwise the llist may be
