aa69546f01 linux 6.0.y: Due to popular demand, allow unofficial Project C port again but make it clear it might be unstable
Since we are either doing ports ourselves or using other's while we wait for Alfred's, let's handle unofficial versions with a toggle "marking" them until proper release eventually becomes available.

4201196110 preempt_rt: Fixups
- get rid of the deprecated _kver_subver_map and related check
- notify the user about the last known good kernel version target of the PREEMPT_RT patchset
- use warning instead of msg2 for PREEMPT_RT patch skipping since we are skipping a very impacting patch explicitly requested by the .cfg

Subject: [PATCH] soundwire: intel: Initialize clock stop timeout
The bus->clk_stop_timeout member is only initialized to a non-zero value
during the codec driver probe. This can lead to corner cases where this
value remains pegged at zero when the bus suspends, which results in an
endless loop in sdw_bus_wait_for_clk_prep_deprep().
Corner cases include configurations with no codecs described in the
firmware, or delays in probing codec drivers.
Initializing the default timeout to the smallest non-zero value avoid this
problem and allows for the existing logic to be preserved: the
bus->clk_stop_timeout is set as the maximum required by all codecs
connected on the bus.

Subject: [PATCH 4/5] drm/sched: add DRM_SCHED_FENCE_DONT_PIPELINE flag
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Setting this flag on a scheduler fence prevents pipelining of jobs
depending on this fence. In other words we always insert a full CPU
round trip before dependen jobs are pushed to the pipeline.

Subject: [PATCH 5/5] drm/amdgpu: use DRM_SCHED_FENCE_DONT_PIPELINE for VM
updates

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Make sure that we always have a CPU round trip to let the submission
code correctly decide if a TLB flush is necessary or not.
