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. config 64BIT bool "64-bit kernel" depends on PA8X00 help Enable this if you want to support 64bit kernel on PA-RISC platform. At the moment, only people willing to use more than 2GB of RAM, or having a 64bit-only capable PA-RISC machine should say Y here. Since there is no 64bit userland on PA-RISC, there is no point to enable this option otherwise.

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, uniprocessor machines. On a uniprocessor machine, the kernel will run faster if you say N here. See also and the SMP-HOWTO available at .

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.
