Avoid potential gcc bug by not using a weak function for

The patch is unreviewable (and hence unusable) if you don't describe
this "potential gcc bug".

gcc-4.1.0 and 4.1.1 were explicitly banned via a test in
include/linux/compiler-gcc4.h for this reason.


OK, no issue then. Sorry for the noise.
