146 This changes the kernel so it can modify itself when it is run
147 under a hypervisor, potentially improving performance significantly
148 over full virtualization. However, when run without a hypervisor
149 the kernel is theoretically slower and slightly larger.

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