146 under a hypervisor, potentially improving performance significantly
147 over full virtualization. However, when run without a hypervisor
148 the kernel is theoretically slower and slightly larger.

370 keep in mind that a kernel compiled for, e.g., 2 CPUs will boot but
371 only use 2 CPUs on a >2 CPU system. Setting this to a value larger
372 than 64 will cause the use of a CPU mask array, causing a small
