include/linux/byteorder: Fix compilation of __constant_cpu_to_be32()
The macro __constant_cpu_to_be32() uses ___constant_swab32(), which for
some reason is not defined and causes the following error during
compilation:
include/linux/byteorder/little_endian.h:28:52: warning:
implicit declaration of function ‘___constant_swab32’;
did you mean ‘__builtin_bswap32’? [-Wimplicit-function-declaration]
#define __constant_cpu_to_be32(x) ((__force __be32)___constant_swab32((x)))
Declare all ___constant_swabXX() macros.
