  	help
  	  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.

  	  Since there is no 64bit userland on PA-RISC, there is no point to

  	  If you say N here, the kernel will run on uni- and multiprocessor

  	  machines, but will use only one CPU of a multiprocessor machine. If
  	  you say Y here, the kernel will run on many, but not all,

  	  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.
