So I have some overall thoughts on the documentation; my apologies for
not getting to this until you got to v4...

1) I think the document is mistitled.  It's not really about the language
   that the kernel used, it's about compiler attributes.  So I would make
   both the name of the document and it introduction reflect that.

2) This is an ideal opportunity to document what all of those attributes
   actually mean.  I would guess that is the information many developers
   will come here looking for, and they'll go away frustrated.  The ideal
   thing to do, IMO, would be do say what each attribute means (rather
   than just which compilers support it) in a DOC section in the new
   compiler_attributes.h header, then use RST directives to pull all that
   information into this document.

Thanks,

jon
