  1559. MIPS R10000 does support a 44 bit / 16TB address space as opposed to
  1560. previous 64-bit processors which only supported 40 bit / 1TB. If you
  1561. need processes of more than 1TB virtual address space, say Y here.
  1562. This will result in additional memory usage, so it is not
  1563. recommended for normal users.

  1567. help
  1568. kexec is a system call that implements the ability to shutdown your
  1569. current kernel, and to start another kernel. It is like a reboot
  1570. but it is independent of the system firmware. And like a reboot
  1571. you can start any kernel with it, not just Linux.
  1572. The name comes from the similarity to the exec system call.
  1573. It is an ongoing process to be certain the hardware in a machine
  1574. is properly shutdown, so do not be surprised if this code does not
  1575. initially work for you. It may help to enable device hotplugging
  1576. support. As of this writing the exact hardware interface is
  1577. strongly in flux, so no good recommendation can be made.

  1582. help
  1583. This kernel feature is useful for number crunching applications
  1584. that may need to compute untrusted bytecode during their
  1585. execution. By using pipes or other transports made available to
  1586. the process as file descriptors supporting the read/write
  1587. syscalls, it's possible to isolate those applications in
  1588. their own address space using seccomp. Once seccomp is
  1589. enabled via /proc/<pid>/seccomp, it cannot be disabled
  1590. and the task is only allowed to execute a few safe syscalls
  1591. defined by each seccomp mode.

  1643. The Extended Industry Standard Architecture (EISA) bus was
