Subject: _RET_IP_ VS __builtin_return_address(0)

Hi,

With a grep search, I find the usage of _RET_IP_ and __builtin_return_address(0)
in current kernel:
_RET_IP_           __builtin_return_address(0)
     89                                128
Actually this isn't matter with the runtime behavior.
But I'm wondering if there is any trend to unify this kind of usage?

Thanks,
Yong
