adceb41688 drm/i915/display: add intel_display_conversion.c to hide stuff better
The __to_intel_display() generics require the definition of struct
drm_i915_private i.e. inclusion of i915_drv.h. Add
intel_display_conversion.c with a __i915_to_display() function to do the
conversion without the intel_display_conversion.h having an implicit
dependency on i915_drv.h.

The long term goal is to remove __to_intel_display() and the
intel_display_conversion.[ch] files altoghether, and this is merely a
transitional step to make the dependencies on i915_drv.h explicit.

17d7072607 drm/i915: extract intel_uncore_trace.[ch]
The i915_reg_rw tracing is a small isolated part of i915_trace.h. Its
users are orthogonal to the other i915_trace.h users as well, and its
implementation does not require all the includes of i915_trace.h. Split
i915_reg_rw tracing to separate intel_uncore_trace.[ch].

The main underlying goal is to reduce implicit includes of i915_drv.h
from display code.

57442cfb45 drm/i915/gvt: always pass struct intel_display * to register macros
The long term goal is to remove the __to_intel_display() generics from
display macros, such as register macros. This requires that all such
macro usage passes struct intel_display * rather than struct
drm_i915_private * to the macros.

The short term goal is to hide the struct drm_i915_private access in
intel_display_conversions.h into a function. This is problematic with
gvt, because it's a separate module, and the conversion function would
need to be exported.

Make the conversion to always passing struct intel_display * in gvt to
unblock both of the above.

df7c8e3dde drm/connector: add mutex to protect ELD from concurrent access
The connector->eld is accessed by the .get_eld() callback. This access
can collide with the drm_edid_to_eld() updating the data at the same
time. Add drm_connector.eld_mutex to protect the data from concurrenct
access. Individual drivers are not updated (to reduce possible issues
while applying the patch), maintainers are to find a best suitable way
to lock that mutex while accessing the ELD data.

4c41a48f5f s390/pci: Add pci_msg debug view to PCI report
Using the newly introduced debug_dump() mechanism add formatted content
of pci_debug_msg_id to the PCI report. The formatting is based on the
existing sprintf format but removes caller pointer and area index and
adds an column header. This will allow the platform to collect this log
data together with hardware errors. This sets the reverse flag such that
the newest log entries get added to the PCI report even if not all debug
log entries fit.

7832b3047d s390/debug: Simplify and document debug_next_entry() logic
Contrary to convention debug_next_entry() returns a falsy 0 value if
there are more entries and a truthy 1 value when there are no more
entries. As there is only one caller just reverse this logic to be less
surprising and document the behavior in a kdoc comment. Also replace the
goto with an early return. In the future this allows using it in
a do {} while (debug_next_entry(...)) loop.

88441d5c6d rust: miscdevice: access the struct miscdevice from fops->open()
Providing access to the underlying `struct miscdevice` is useful for
various reasons. For example, this allows you access the miscdevice's
internal `struct device` for use with the `dev_*` printing macros.

Note that since the underlying `struct miscdevice` could get freed at
any point after the fops->open() call (if misc_deregister is called),
only the open call is given access to it. To use `dev_*` printing macros
from other fops hooks, take a refcount on `miscdevice->this_device` to
keep it alive. See the linked thread for further discussion on the
lifetime of `struct miscdevice`.
