Including; add missing documentation for function arguments, re-ordering
of #defines i.e. not placed between kerneldoc headers and the functions
they are documenting, demotion of file header/comment from kerneldoc
format and removal of documentation for non-existent args.

Fixes the following W=1 kernel build warnings:
