191           If you configure the kernel to include many drivers built-in instead
192           as modules, the kernel executable may become too big, so that the
193           linker will not be able to resolve some long branches and fails to link
194           your vmlinux kernel. In that case enabling this option will help you
195           to overcome this limit by using the -mlong-calls compiler option.

197           Usually you want to say N here, unless you e.g. want to build

199           be used for TFTP booting without the need to have an initrd ramdisk.

343           the process as file descriptors supporting the read/write
344           syscalls, it's possible to isolate those applications in
345           their own address space using seccomp. Once seccomp is
346           enabled via prctl(PR_SET_SECCOMP), it cannot be disabled
347           and the task is only allowed to execute a few safe syscalls
348           defined by each seccomp mode.
