Fix a few problems I discovered when building a kernel with upstream CVS
binutils.
We have to add the NOTES macro to our linker script, since a kernel
built with --build-id is otherwise unable to boot. Last time NOTES was
added, it broke things, but the definition of the macro has changed not
to rely on parts of the linker script that aren't present on Blackfin.
I also noticed that _l2_lma_start does not point into the kernel image,
but rather somewhere in L1/L2 space, which seems unintended. Also, when
the L2 section was added to the linker script, the part following it which
computes then length of the init section was not updated.

Remove all traces of the relocation stack. It's been removed from
binutils for years now.
Add a sanity overflow check to pcrel24 relocations to catch modules that
were built without -mlong-calls.

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.

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).

Impact: change calling convention of existing clock_event APIs
struct clock_event_timer's cpumask field gets changed to take pointer,
as does the ->broadcast function.
Another single-patch change. For safety, we BUG_ON() in
clockevents_register_device() if it's not set.
