[Why]
Resolve compiler warnings by marking unused parameters explicitly.

[How]
In .c and .h function definitions, keep parameter names
in signatures and add a line with `(void)param;` in function body

Preserved function signatures and avoids breaking code paths that
may reference the parameter under conditional compilation.

[WHY]
Improve the output when using the ftrace debug feature,
making it easier to identify which function is currently being executed.

[HOW]
Rename the program_timing function to a name that
includes the path to the function's file.

OTG has new functionality to allow P-State relative to VStartup. Keepout region
for this should be configured based on DML outputs same as other global sync

<title>kbuild: make -Woverride-init warnings more consistent</title>
<updated>2024-03-31T02:32:26+00:00</updated>

<id>c40845e3195d074b34f8f8e400e28c9403a06588</id>
<content type='text'>
The -Woverride-init warn about code that may be intentional or not,
but the inintentional ones tend to be real bugs, so there is a bit of
disagreement on whether this warning option should be enabled by default
and we have multiple settings in scripts/Makefile.extrawarn as well as
individual subsystems.

Older versions of clang only supported -Wno-initializer-overrides with
the same meaning as gcc's -Woverride-init, though all supported versions
now work with both. Because of this difference, an earlier cleanup of
mine accidentally turned the clang warning off for W=1 builds and only
left it on for W=2, while it's still enabled for gcc with W=1.

There is also one driver that only turns the warning off for newer
versions of gcc but not other compilers, and some but not all the
Makefiles still use a cc-disable-warning conditional that is no
longer needed with supported compilers here.

Address all of the above by removing the special cases for clang
and always turning the warning off unconditionally where it got
in the way, using the syntax that is supported by both compilers.
