Improve LogicalCpu{Id,Set}, make set atomic.
...
Technically there should be an atomic and nonatomic set type, but perf
should be the same, as the nonatomic one would only be used when setting
the sched_affinity.

Since clone is no longer exists as a syscall, it makes little sense to
manage vfork in the kernel. Implementing vfork in userspace would still
be possible.
