  SVN rev 180808 on 2008-07-25 17:46:01Z by jhb
  
  MFC: Add cpuset, an api for thread to cpu binding and cpu resource grouping
  and assignment.  This is mostly synched up with what is in HEAD with the
  following exceptions:
  - I didn't MFC any of the interrupt binding stuff as it requires other
    changes and I figured this change was large enough as it is.
  - The sched_affinity() implementation for ULE in HEAD depends on the newer
    CPU topology stuff as well as other changes in ULE.  Rather than
    backport all of that, I implemented sched_affinity() using the existing
    CPU topology and ULE code in 7.x.  Thus, any bugs in the ULE affinity
    stuff in 7 are purely my fault and not Jeff's.
  
  Note that, just as in HEAD, cpusets currently don't work on SCHED_4BSD (the
  syscalls will succeed, but they don't have any effect).
