Matthew Wilcox ea43546750 atomic_t: unify all arch definitions
The atomic_t type cannot currently be used in some header files because it
would create an include loop with asm/atomic.h.  Move the type definition
to linux/types.h to break the loop.

Rusty Russell ccec25ff69 blackfin: define __fls
Like fls, but can't be handed 0 and returns the bit number.

(I broke this arch in linux-next by using __fls in generic code).

when copying L1 regions, go to the start of bss rather
than end since we have code to zero it out already
