2078 | This allows you to specify the maximum number of CPUs which this | |
2079 | kernel will support. The maximum supported value is 32 for 32-bit | |
2080 | kernel and 64 for 64-bit kernels; the minimum value which makes | |

2081 | sense is 1 for Qemu (useful only for kernel debugging purposes) |
2082 | and 2 for all others. | |
