I think it is, we decided a bit ago that spinlock based atomics
were a bad idea, and even with that the spinlock atomic_t implementations
do not take the lock in their atomic_read() implementation, they merely
wait to get a sample with the lock clear.

doesn't necessary mean outright rejection so resend.
I'm going to apply Stephen's patch.
