    Implement several enhancements to NUMA policies.
    
    Add a new "interleave" allocation policy which stripes pages across
    domains with a stride or width keeping contiguity within a multi-page
    region.
    
    Move the kernel to the dedicated numbered cpuset #2 making it possible
    to assign kernel threads and memory policy separately from user.  This
    also eliminates the need for the complicated interrupt binding code.
    
    Add a sysctl API for viewing and manipulating domainsets.  Refactor some
    of the cpuset_t manipulation code using the generic bitset type so that
    it can be used for both.  This probably belongs in a dedicated subr file.
    
    Attempt to improve the include situation.
