The clean up of CALLER_ADDR*() functions required the archs to either use the default __builtin_return_address(X) (where X > 0) or override it with something the arch can use. To override it, the arch would define function_return_address(x).
The arm architecture requires this to be redefined but instead of defining function_return_address(x) it defined function_return_addr(x).
