From: Guan Xuetao <gxt@mprc.pku.edu.cn>

3.4.104-rc1 review patch. If anyone has any objections, please let me know.

------------------

commit 195d4577d1d7ab1f0398b3190547c116b56f435f upstream.

When disintegrate system.h, I left an error in asm/cmpxchg.h, which
will result in following error:

arch/unicore32/include/asm/cmpxchg.h: In function '__xchg':
arch/unicore32/include/asm/cmpxchg.h:38: error: void value not ignored as it ought to be
