Subject: [PATCH 0/5] refcount_t and various related bits

Hi all,

Here is the refcount_t patch and some related bits that I hacked up the past
few days while playing with it in order to make it generate less aweful code
(on x86_64).

I think we can start by merging the refcount_t and kref patches, the rest can
come later if so desired. New here is the Kconfig knob to turn warnings
off -- it significantly reduces the generated code while still avoiding
the UAF.

I added David Howells because both he and hpa have suggested something like
try_cmpxchg() in the past.
