 With reasonable understanding what the MIPS architecture features covered 
by these macros, functions, etc. are you should be able to infer from 
Linux code what it actually does.

 May I suggest some reading on the architecture first then?  I realise 
MIPS Technologies' architecture specifications may not be the best way to 
learn how the architecture works, so why not try a MIPS textbook instead, 
such as Dominic Sweetman's excellent "See MIPS Run Linux" (ISBN 
978-0-12-088421-6)?  While not covering such details of Linux as you are 
looking for, it includes related introductory subjects to get you started.  
And of course it covers the MIPS architecture itself.  You may be able to 
find the book at your nearby (or less near) library.

 I think it's about as much as we can help -- you need to get down to 
understanding the details yourself or you'll be bound to asking around 
helplessly all the time.
