1) It makes MC documentation consistend with other parts;
2) The header file can be used as a quick index to all API
elements;
3) The cross-reference check helps to identify symbols that
aren't documented.

The function that replace references add a "\ " at the end of
references, to avoid the ReST markup parser to not identify
them as references. That works fine except for the end of lines,

The kernel-include directive is needed to include the auto generated rst
content from a build (pre-) process. E.g. the linux_tv Makefile
generates intermediate reST-files from header files. Since there is a O=
option:
make O=dir [targets] Locate all output files in "dir"
We need to include intermediate reST files from arbitrary (O=/tmp/foo)
locations:
The 'kernel-include' reST-directive is a replacement for the 'include'
directive. The 'kernel-include' directive expand environment variables
in the path name and allows to include files from arbitrary locations.
.. hint::
Including files from arbitrary locations (e.g. from '/etc') is a
security risk for builders. This is why the 'include' directive from
docutils *prohibit* pathnames pointing to locations *above* the
filesystem tree where the reST document with the include directive is
placed.
Substrings of the form $name or ${name} are replaced by the value of
environment variable name. Malformed variable names and references to
non-existing variables are left unchanged.
