1888 MIPS R10000 does support a 44 bit / 16TB address space as opposed to
1889 previous 64-bit processors which only supported 40 bit / 1TB. If you
1890 need processes of more than 1TB virtual address space, say Y here.
1891 This will result in additional memory usage, so it is not
1892 recommended for normal users.
1895 bool "Kexec system call (EXPERIMENTAL)"
1896 depends on EXPERIMENTAL
1898 kexec is a system call that implements the ability to shutdown your
1899 current kernel, and to start another kernel. It is like a reboot
1900 but it is indepedent of the system firmware. And like a reboot
1901 you can start any kernel with it, not just Linux.
1903 The name comes from the similiarity to the exec system call.
1905 It is an ongoing process to be certain the hardware in a machine
1906 is properly shutdown, so do not be surprised if this code does not
1907 initially work for you. It may help to enable device hotplugging
1908 support. As of this writing the exact hardware interface is
1909 strongly in flux, so no good recommendation can be made.
1912 bool "Enable seccomp to safely compute untrusted bytecode"
1913 depends on PROC_FS && BROKEN
1916 This kernel feature is useful for number crunching applications
1917 that may need to compute untrusted bytecode during their
1918 execution. By using pipes or other transports made available to
1919 the process as file descriptors supporting the read/write
1920 syscalls, it's possible to isolate those applications in
1921 their own address space using seccomp. Once seccomp is
1922 enabled via /proc/<pid>/seccomp, it cannot be disabled
1923 and the task is only allowed to execute a few safe syscalls
1924 defined by each seccomp mode.
1926 If unsure, say Y. Only embedded should say N here.

2036 A 64-bit kernel is usually built using the 64-bit ELF binary object
2037 format as it's one that allows arbitrary 64-bit constructs. For
2038 kernels that are loaded within the KSEG compatibility segments the
2039 32-bit ELF format can optionally be used resulting in a somewhat
2040 smaller binary, but this option is not explicitly supported by the
2041 toolchain and since binutils 2.14 it does not even work at all.
