There are behavioural requirements on the seq_file next() function in
terms of how it updates *pos at end-of-file, and these are now enforced
by a warning.

I was recently attempting to justify the reason this was needed, and
couldn't remember the details, and didn't find them in the
documentation.

So I re-read the code until I understood it again, and updated the
documentation to match.

I also enhanced the text about SEQ_START_TOKEN as it seemed potentially
misleading.

The command-line parameters "dyndbg" and "async_probe" are not
parameters for kernel/module.c but instead they are for the
module that is being loaded. Try to make that distinction in the
help text.

OTOH, "module.sig_enforce" is handled as a parameter of kernel/module.c
so "module." is correct for it.

Subroutine dump_struct uses type attributes to check if the struct
syntax is valid. Then, it removes all attributes before using it for
output. `____cacheline_aligned` is an attribute that is
not included in both steps. Add it, since it is used by kernel structs.

Based on previous patch to add ____cacheline_aligned_in_smp.
Motivated by patches to reorder this attribute to before the
variable name.   Whilst we could do that in all cases, that would
be a massive change and it is more common in the kernel to place
this particular attribute after the variable name. A quick grep
suggests approximately 400 instances of which 341 have this
attribute just before a semicolon and hence after the variable name.

Cross-referencing to other documentation pages is possible using the
:doc:`doc-file` directive from Sphinx.

Add automatic markup for references to other documentation pages in the
format Documentation/subfolder/doc-file.rst (the extension being
optional).
This requires that the path be passed all the way from the Documentation
folder, which can be longer than passing a relative path through the
:doc: directive, but avoids the markup, making the text cleaner when
read in plain text.
