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).
