Subject: [PATCH v2 0/9] refcount: Improve code-gen

Hi,

Now with Linus' favourite refcount scheme on :-)

Changes since RFC:

 - more cleanups in scripts/atomic/
 - rename atomic_*_ofl() to atomic_*_overflow() (null)
 - alternative x86 refcount scheme (Linus)
 - fix for refcount_dec_not_one()
 - opt __refcount_add_not_zero(.i=1)

Boots x86_64 and builds a kernel.
