I am curious why 'unsinged long' > won't work? Is it b/c on ARM you always want a 64-bit type? Yes, we would like to make the same interface work for 32 and 64 bit guests, without any need for a "compat layer" as we currently have on x86. In fact I am going to add another patch to explicitly size all the other unsigned long that we have in the public interface. _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
