Processor features are stored in a union containing two "banks":union hv_partition_processor_features { uint64_t as_uint[2]; struct { uint64_t sse3_support:1; ... } } get_proc_features() to retrieve the 2nd bank was passing a pointer that steps over the whole union (+16B) instead of picking the 2nd bank _in_ the union. This manifests in mismatching feature bits for the 2nd bank and possibly other side-effects caused by writing beyond the union. We need to step over the first bank (+8B) by using as_uint64[0/1] to correct this behaviour.
