[patch 09/23] Add cmpxchg_local, cmpxchg64 and cmpxchg64_local to ia64
Add the primitives cmpxchg_local, cmpxchg64 and cmpxchg64_local to ia64. They use cmpxchg_acq as underlying macro, just like the already existing ia64 cmpxchg(). Changelog: ia64 cmpxchg_local coding style fix Quoting Keith Owens: As a matter of coding style, I prefer #define cmpxchg_local cmpxchg #define cmpxchg64_local cmpxchg64 Which makes it absolutely clear that they are the same code. With your patch, humans have to do a string compare of two defines to see if they are the same.
