[POWERPC] Use __always_inline for xchg* and cmpxchg*
This changes the definitions of the xchg and cmpxchg families of functions in include/asm-powerpc/system.h to be marked __always_inline rather than __inline__. The reason for doing this is that we rely on the compiler inlining them in order to eliminate the references to __xchg_called_with_bad_pointer and __cmpxchg_called_with_bad_pointer, which are deliberately left undefined. Thus this change will enable us to make the inline keyword be just a hint rather than a directive. Signed-off-by: Paul Mackerras <paulus@samba.org>
