193 | help | |
194 | If you configure the kernel to include many drivers built-in instead | |
195 | as modules, the kernel executable may become too big, so that the | |
196 | linker will not be able to resolve some long branches and fails to link | |
197 | your vmlinux kernel. In that case enabling this option will help you | |
198 | to overcome this limit by using the -mlong-calls compiler option. | |
199 | ||
200 | Usually you want to say N here, unless you e.g. want to build | |
201 | a kernel which includes all necessary drivers built-in and which can | |
202 | be used for TFTP booting without the need to have an initrd ramdisk. | |

214 | ||
215 | Since there is no 64bit userland on PA-RISC, there is no point to | |
216 | enable this option otherwise. The 64bit kernel is significantly bigger | |

226 | This lets you select the page size of the kernel. For best | |

253 | than one CPU, say Y. | |
254 | ||
255 | If you say N here, the kernel will run on uni- and multiprocessor | |
256 | machines, but will use only one CPU of a multiprocessor machine. If | |
257 | you say Y here, the kernel will run on many, but not all, | |
258 | uniprocessor machines. On a uniprocessor machine, the kernel | |
259 | will run faster if you say N here. | |

343 | This kernel feature is useful for number crunching applications | |
344 | that may need to compute untrusted bytecode during their | |
345 | execution. By using pipes or other transports made available to | |
346 | the process as file descriptors supporting the read/write | |
347 | syscalls, it's possible to isolate those applications in | |
348 | their own address space using seccomp. Once seccomp is | |
349 | enabled via prctl(PR_SET_SECCOMP), it cannot be disabled | |
350 | and the task is only allowed to execute a few safe syscalls | |
351 | defined by each seccomp mode. | |
