[PATCH] add bottom_half.h
With CONFIG_SMP=n:
drivers/input/ff-memless.c:384: warning: implicit declaration of function 'local_bh_disable'
drivers/input/ff-memless.c:393: warning: implicit declaration of function 'local_bh_enable'
Really linux/spinlock.h should include linux/interrupt.h. But interrupt.h
includes sched.h which will need spinlock.h.
So the patch breaks the _bh declarations out into a separate header and
includes it in both interrupt.h and spinlock.h.
