H A D | atomic.h | diff 237f12337cfa2175474e4dd015bc07a25eb9080d Sat Oct 26 09:07:04 CDT 2013 Chen Gang <gang.chen@asianux.com> ARM: 7866/1: include: asm: use 'long long' instead of 'u64' within atomic.h
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.
