This was on x86-64 right?

That function is implemented in the generic atomic64 implementation
and my x86-32 version, but not in the x86-64 implementation.

There is a similar problem with the 32-bt atomic_dec_if_positive, that
is implemented by ppc, mips, microblaze and avr32 but not in x86-32
and asm-generic.
Currently the 64-bit version seems unused, while the 32-bit one seems
to be only used by ppc-only drivers (IBM pSeries virtual SCSI and
PlayStation3 drivers).

I'll send a couple of patches to fix this shortly.
