compile error in __cmpxchg_u32

Hi,

I found following error in 2.6, when I compiled.

include/asm/system.h: In function `__cmpxchg_u32':
include/asm/system.h:407: error: `val' undeclared (first use in this function)
include/asm/system.h:407: error: (Each undeclared identifier is reported only 
once
include/asm/system.h:407: error: for each function it appears in.)

I made patch. Is this patch right?
