Log Message:
x86: Defer x86_rndseed until after pmap_bootstrap.
Loading the random seed, which is what x86_rndseed does, requires
direct map access on KASLR kernels, which requires pmap_bootstrap to
have run.
This had been broken in
amd64/machdep.c 1.359
i386/machdep.c 1.832
because we apparently don't have any automatic test setup for KASLR
kernels, which we should address.
This change shouldn't cause any security regression on kernels that
previously owrked, because none of the logic that now happens before
x86_rndseed uses the entropy pool anyway (uvm_md_init,
init_x86_clusters, xen_parse_cmdline).
