not per-process. Keep it in `switchtime' consistently. It is now clear that the timestamp is always valid in fork_trampoline() except when the child is running on a previously idle cpu, which can only happen if there are multiple cpus, so don't check or set the timestamp in fork_trampoline except in the (i386) SMP case. Just remove the alpha code for setting it unconditionally, since there is no SMP case for alpha and the code had rotted. Parts reviewed by: dfr, phk
