[PATCH] headers: enable ppc64 ___arch__swab16 and ___arch__swab32
This patch cleans up asm-ppc64/byteorder.h to enable ___arch__swab16 and ___arch__swab32 which are marked TODO currently. It removes ___arch__swab64 because ppc64 does not have short instruction combinations for swab64, the recent gcc generates enough smart code that is equivalent to hand assembled code under my tests.
