The regular atomic_long_*() wrappers are built atop these, as we do for {atomic,atomic64}_*() atop arch_{atomic,atomic64}_*(). We don't provide arch_* versions of the cond_read*() variants, as we don't have arch_* versions of the underlying atomic/atomic64 functions (nor the smp_cond_load*() helpers these are typically based on). Note that the headers in this patch under include/linux/atomic/ are generated by the scripts in scripts/atomic/.

This patch centralizes them under include/linux/atomic/. Other than the header guards and hashes, there is no change to any of the generated headers as a result of this patch.
