Subject: "(unsigned long)__builtin_return_address(0)", _RET_IP_, CALLER_ADDR0?


as another possibility for standardizing code, is there a standard
for the simplification mentioned in the subject and documented here:

http://www.crashcourse.ca/wiki/index.php/The_style_script#Testing_for_.22.28unsigned_long.29__builtin_return_address.280.29.22_simplification

it's a bit confusing that, even within the kernel/ directory, all
three constructs are used, even sometimes being mixed in the same
source file, which is really more confusing than it has to be.

is there a standard?
