182 help
183 If you configure the kernel to include many drivers built-in instead
184 as modules, the kernel executable may become too big, so that the
185 linker will not be able to resolve some long branches and fails to link
186 your vmlinux kernel. In that case enabling this option will help you
187 to overcome this limit by using the -mlong-calls compiler option.
188
189 Usually you want to say N here, unless you e.g. want to build
190 a kernel which includes all necessary drivers built-in and which can
191 be used for TFTP booting without the need to have an initrd ramdisk.

201 At the moment, only people willing to use more than 2GB of RAM,
202 or having a 64bit-only capable PA-RISC machine should say Y here.
203
204 Since there is no 64bit userland on PA-RISC, there is no point to
205 enable this option otherwise. The 64bit kernel is significantly bigger

332 This kernel feature is useful for number crunching applications
333 that may need to compute untrusted bytecode during their
334 execution. By using pipes or other transports made available to
335 the process as file descriptors supporting the read/write
336 syscalls, it's possible to isolate those applications in
337 their own address space using seccomp. Once seccomp is
338 enabled via prctl(PR_SET_SECCOMP), it cannot be disabled
339 and the task is only allowed to execute a few safe syscalls
340 defined by each seccomp mode.
341
342 If unsure, say Y. Only embedded should say N here.
