The patch allows one to configure NR_CPUS >8 (16 by default, same as the
native) for x86_64 xenlinux. I tested 16-way xenolinux (using changeset

as I did sanity tests like kernel build (make -j64).

          This allows you to specify the maximum number of CPUs which this
          kernel will support.  The maximum supported value is 32 and the
