          Qemu is a software emulator which among other architectures also
          can simulate a MIPS32 4Kc system.  This patch adds support for the
          system architecture that currently is being simulated by Qemu.  It
          will eventually be removed again when Qemu has the capability to
          simulate actual MIPS hardware platforms.  More information on Qemu

          This allows you to specify the maximum number of CPUs which this
          kernel will support.  The maximum supported value is 32 for 32-bit
          kernel and 64 for 64-bit kernels; the minimum value which makes
          sense is 2.

          This is purely to save memory - each supported CPU adds
          approximately eight kilobytes to the kernel image.

          MIPS R10000 does support a 44 bit / 16TB address space as opposed to

config KEXEC

        help
          kexec is a system call that implements the ability to shutdown your
          current kernel, and to start another kernel.  It is like a reboot
          but it is indepedent of the system firmware.   And like a reboot
          you can start any kernel with it, not just Linux.

          The name comes from the similiarity to the exec system call.

          It is an ongoing process to be certain the hardware in a machine
          is properly shutdown, so do not be surprised if this code does not
          initially work for you.  It may help to enable device hotplugging
          support.  As of this writing the exact hardware interface is
          strongly in flux, so no good recommendation can be made.

          This kernel feature is useful for number crunching applications
          that may need to compute untrusted bytecode during their
          execution. 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 /proc/<pid>/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.

          The Extended Industry Standard Architecture (EISA) bus was
          developed as an open alternative to the IBM MicroChannel bus.

          The EISA bus provided some of the features of the IBM MicroChannel
          bus while maintaining backward compatibility with cards made for
          the older ISA bus.  The EISA bus saw limited use between 1988 and
          1995 when it was made obsolete by the PCI bus.

          Say Y here if you are building a kernel for an EISA-based machine.

          smaller binary, but this option is not explicitly supported by the
