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.
Note cmpxchg is *not* a performance win vs interrupt disable / enable on IA64.
