1842 This allows you to specify the maximum number of CPUs which this
1843 kernel will support. The maximum supported value is 32 for 32-bit
1844 kernel and 64 for 64-bit kernels; the minimum value which makes
1845 sense is 1 for Qemu (useful only for kernel debugging purposes)
1846 and 2 for all others.
1848 This is purely to save memory - each supported CPU adds
1849 approximately eight kilobytes to the kernel image. For best
1850 performance should round up your number of processors to the next

1930 MIPS R10000 does support a 44 bit / 16TB address space as opposed to
1931 previous 64-bit processors which only supported 40 bit / 1TB. If you
1932 need processes of more than 1TB virtual address space, say Y here.
1933 This will result in additional memory usage, so it is not

1937 bool "Kexec system call (EXPERIMENTAL)"
1938 depends on EXPERIMENTAL
1940 kexec is a system call that implements the ability to shutdown your
1941 current kernel, and to start another kernel. It is like a reboot
1942 but it is indepedent of the system firmware. And like a reboot
1943 you can start any kernel with it, not just Linux.
1945 The name comes from the similiarity to the exec system call.
1947 It is an ongoing process to be certain the hardware in a machine
1948 is properly shutdown, so do not be surprised if this code does not
1949 initially work for you. It may help to enable device hotplugging
1950 support. As of this writing the exact hardware interface is
1951 strongly in flux, so no good recommendation can be made.
1954 bool "Enable seccomp to safely compute untrusted bytecode"
1955 depends on PROC_FS && BROKEN
1958 This kernel feature is useful for number crunching applications
1959 that may need to compute untrusted bytecode during their
1960 execution. By using pipes or other transports made available to
1961 the process as file descriptors supporting the read/write
1962 syscalls, it's possible to isolate those applications in
1963 their own address space using seccomp. Once seccomp is
1964 enabled via /proc/<pid>/seccomp, it cannot be disabled
1965 and the task is only allowed to execute a few safe syscalls
1966 defined by each seccomp mode.
1968 If unsure, say Y. Only embedded should say N here.

2080 kernels that are loaded within the KSEG compatibility segments the
2081 32-bit ELF format can optionally be used resulting in a somewhat
2082 smaller binary, but this option is not explicitly supported by the
