This is V4 of my submission.  Here is a list of requested changes:

   o Extra commit was added for changing an unsigned short to an int.
   o Use of EXTERN_SYMBOL was added to mips-atomic.c and bitops.c,
     as well as the removal of 'extern' in the functions' declarations.
   o Name of funcs changed from atomic_xxx to __mips_xxx in bitops.c.
   o The function comments in bitops.c were tweaked to please

Here is a list of requested changes that were not done (and why):

   o Suggested optimization of _MIPS_SZLONG and others was not needed
     as mips-atomic.c now includes <asm/irqflags.h>.
   o Suggested fixes to please for whitespace before
     newlines in asm strings was attempted but the result made the
     assembly code look more cluttered => no change made.

These were unrequested changes:
   o Changed order of func listings in irqflags.h so that only one
     #ifdef/#endif pair was needed instead of three.

FWIW: I haven't tested these, but...
