41 | This defines the number of virtual interrupt numbers the kernel | |

43 | /proc/interrupts. If you configure your system to have too few, | |

917 | This option enables the kernel to be loaded at any page aligned | |
918 | physical address. The kernel creates a mapping from KERNELBASE to | |
919 | the address where the kernel is loaded. The page size here implies | |
