Without getting into an argument about which definition of "seed" is
correct --- it's certainly confusing and different form the RDSEED
usage of the word "seed".
Do we expect that anyone else besides arch_get_rnd_seed() would
actually want to use it? I'd argue no; we want the rest of the kernel
to either use get_random_bytes() or prandom_u32(). Given that, maybe
we should just call it arch_random_init(), and expect that the only
user of this interface would be drivers/char/random.c?
