2103 the entropy pool as well. If neither RDRAND nor RDTSC are
2104 supported, then entropy is read from the i8254 timer. The
2105 usable entropy is limited by the kernel being built using
2107 minimum of 2MB. As a result, only 10 bits of entropy are
2173 for memory hotplug support but reduces the entropy available for
