I mean, the fix consists in making sure that attr.config has all the 64 bits cleared - on the 64 bit machines, int is 64bit, so u64 == int, and all the bits are correctly handled. on 32 bit machines, int is 32bit, and the top 32 bit of attr.config is not cleared.

I may be wrong though, as I didn't scan through all the affected code.
