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

	  Usually you want to say N here, unless you e.g. want to build
	  a kernel which includes all necessary drivers built-in and which can
	  be used for TFTP booting without the need to have an initrd ramdisk.

	  Enabling this option will probably slow down your kernel.

	  At the moment, only people willing to use more than 2GB of RAM,

	  Since there is no 64bit userland on PA-RISC, there is no point to
	  enable this option otherwise. The 64bit kernel is significantly bigger
	  and slower than the 32bit one.

	  This kernel feature is useful for number crunching applications

	  execution. By using pipes or other transports made available to
	  the process as file descriptors supporting the read/write
	  syscalls, it's possible to isolate those applications in
	  their own address space using seccomp. Once seccomp is
	  enabled via prctl(PR_SET_SECCOMP), it cannot be disabled
	  and the task is only allowed to execute a few safe syscalls
	  defined by each seccomp mode.

	  If unsure, say Y. Only embedded should say N here.
