sparc64: Make atomic_xchg() an inline function rather than a macro.
[ Upstream commit d13864b68e41c11e4231de90cf358658f6ecea45 ]
This avoids a lot of -Wunused warnings such as:
====================
kernel/debug/debug_core.c: In function ‘kgdb_cpu_enter’:
./arch/sparc/include/asm/cmpxchg_64.h:55:22: warning: value computed is not used [-Wunused-value]
#define xchg(ptr,x) ((__typeof__(*(ptr)))__xchg((unsigned long)(x),(ptr),sizeof(*(ptr))))
./arch/sparc/include/asm/atomic_64.h:86:30: note: in expansion of macro ‘xchg’
#define atomic_xchg(v, new) (xchg(&((v)->counter), new))
^~~~
kernel/debug/debug_core.c:508:4: note: in expansion of macro ‘atomic_xchg’
atomic_xchg(&kgdb_active, cpu);
^~~~~~~~~~~
