-	  Modern versions of GCC (since 4.4) have builtin functions
-	  for handling byte-swapping. Using these, instead of the old
-	  inline assembler that the architecture code provides in the
-	  __arch_bswapXX() macros, allows the compiler to see what's
-	  happening and offers more opportunity for optimisation. In
-	  particular, the compiler will be able to combine the byteswap
-	  with a nearby load or store and use load-and-swap or
-	  store-and-swap instructions if the architecture has them. It
-	  should almost *never* result in code which is worse than the
-	  hand-coded assembler in <asm/swab.h>.  But just in case it
