1927 MIPS R10000 does support a 44 bit / 16TB address space as opposed to
1928 previous 64-bit processors which only supported 40 bit / 1TB. If you
1929 need processes of more than 1TB virtual address space, say Y here.

1931 recommended for normal users.
1934 bool "Kexec system call (EXPERIMENTAL)"
1935 depends on EXPERIMENTAL
1937 kexec is a system call that implements the ability to shutdown your
1938 current kernel, and to start another kernel. It is like a reboot
1939 but it is indepedent of the system firmware. And like a reboot
1940 you can start any kernel with it, not just Linux.
1942 The name comes from the similiarity to the exec system call.
1944 It is an ongoing process to be certain the hardware in a machine
1945 is properly shutdown, so do not be surprised if this code does not
1946 initially work for you. It may help to enable device hotplugging
1947 support. As of this writing the exact hardware interface is
1948 strongly in flux, so no good recommendation can be made.
1951 bool "Enable seccomp to safely compute untrusted bytecode"
1952 depends on PROC_FS && BROKEN
1955 This kernel feature is useful for number crunching applications
1956 that may need to compute untrusted bytecode during their
1957 execution. By using pipes or other transports made available to
1958 the process as file descriptors supporting the read/write
1959 syscalls, it's possible to isolate those applications in
1960 their own address space using seccomp. Once seccomp is
1961 enabled via /proc/<pid>/seccomp, it cannot be disabled
1962 and the task is only allowed to execute a few safe syscalls
1963 defined by each seccomp mode.
1965 If unsure, say Y. Only embedded should say N here.
