atomic* value is signed value, and atomic* functions need also process signed value (parameter value, and return value), so 32-bit arm need use 'long long' instead of 'u64'. After replacement, it will also fix a bug for atomic64_add_negative(): "u64 is never less than 0". The modifications are: in vim, use "1,% s/\<u64\>/long long/g" command. remove '__aligned(8)' which is useless for 64-bit. be sure of 80 column limitation after replacement.
