(In reply to ben from comment #28)
I think your patch is in the right direction, but I think the explicit memory
barriers are overkill in part. We likely need to use acq/rel semantics with
the atomics, and always do a load_acq() when checking cpu_done.
Something like using:
atomic_add_rel_int(&cpu_done, 1); (in both cases)
while (atomic_load_acq_int(&cpu_done) < mp_ncpus)
;
And maybe do the same for tb_ready.
