Yes, this seems also fixe the compile warning:
CC arch/i386/power/cpu.o
/home/coywolf/2.6.12-rc3-mm1-cy2/arch/i386/power/cpu.c: In function
`__restore_processor_state':
/home/coywolf/2.6.12-rc3-mm1-cy2/arch/i386/power/cpu.c:137: warning:
implicit declaration of function `enable_sep_cpu'
LD arch/i386/power/built-in.o
I was trying to fix it too. You are quicker and better than me.
