Bruce Evans e7ba67f274 Removed all traces of `p_switchtime'. The relevant timestamp is per-cpu,
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.
