206 help
207 If you configure the kernel to include many drivers built-in instead
208 as modules, the kernel executable may become too big, so that the
209 linker will not be able to resolve some long branches and fails to link
210 your vmlinux kernel. In that case enabling this option will help you
211 to overcome this limit by using the -mlong-calls compiler option.
212
213 Usually you want to say N here, unless you e.g. want to build
214 a kernel which includes all necessary drivers built-in and which can
215 be used for TFTP booting without the need to have an initrd ramdisk.

225 At the moment, only people willing to use more than 2GB of RAM,
226 or having a 64bit-only capable PA-RISC machine should say Y here.
227
228 Since there is no 64bit userland on PA-RISC, there is no point to
229 enable this option otherwise. The 64bit kernel is significantly bigger

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

368 This kernel feature is useful for number crunching applications
369 that may need to compute untrusted bytecode during their
370 execution. By using pipes or other transports made available to
371 the process as file descriptors supporting the read/write
372 syscalls, it's possible to isolate those applications in
373 their own address space using seccomp. Once seccomp is
374 enabled via prctl(PR_SET_SECCOMP), it cannot be disabled
375 and the task is only allowed to execute a few safe syscalls
376 defined by each seccomp mode.
377
