[PATCH V4 0/3] MIPS: make funcs preempt-safe for non-mipsr2 cpus

["Jim Quinlan" <jim2101024@gmail.com>]

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 
    scripts/kernel-doc.

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 checkpatch.pl 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.
