    sys/sun4v/include    endian.h 
  Log:
  In the replacement text of the __bswapN_const() macros encapsulate the
  argument in parentheses so these macros are safe to use and invocations
  with an expression as the argument like __bswap32_const(42 << 23 | 13)
  work as expected. Additionally, mask all the individually shifted bytes
  as appropriate so the bytes which exceed the width of the respective
  __bswapN_const() macro in invocations like __bswap16_const(0xdead600d)
  are ignored like it's the case with the corresponding __bswapN_var()
  function.
