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

198 At the moment, only people willing to use more than 2GB of RAM,
199 or having a 64bit-only capable PA-RISC machine should say Y here.
200
201 Since there is no 64bit userland on PA-RISC, there is no point to

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