Summary: CONFIG_EXCEPTION_L1_SCRATCH causes link failure in kernel

Details:

seems when bf561-smp support was merged, the way the exception_stack is handled was changed and so broke things:

LD .tmp_vmlinux1

arch/blackfin/mm/built-in.o: In function `init_pda':

arch/blackfin/mm/init.c:120: undefined reference to `exception_stack'

make: *** [.tmp_vmlinux1] Error 1

the old code did not refer to "exception_stack", it always referred to "exception_stack_top" ...

Move these exception_stack defines to mm/init.c.

It is fixed.
