557 can simulate a MIPS32 4Kc system. This patch adds support for the

559 will eventually be removed again when Qemu has the capability to
560 simulate actual MIPS hardware platforms. More information on Qemu

1904 format as it's one that allows arbitrary 64-bit constructs. For
1905 kernels that are loaded within the KSEG compatibility segments the
1906 32-bit ELF format can optionally be used resulting in a somewhat
1907 smaller binary, but this option is not explicitly supported by the
1908 toolchain and since binutils 2.14 it does not even work at all.

1910 Say Y to use the 64-bit format or N to use the 32-bit one.

1961 This kernel feature is useful for number crunching applications
1962 that may need to compute untrusted bytecode during their
1963 execution. By using pipes or other transports made available to
1964 the process as file descriptors supporting the read/write
1965 syscalls, it's possible to isolate those applications in
1966 their own address space using seccomp. Once seccomp is
1967 enabled via /proc/<pid>/seccomp, it cannot be disabled
1968 and the task is only allowed to execute a few safe syscalls
1969 defined by each seccomp mode.

1980 ---help---
1981 APM is a BIOS specification for saving power using several different
1982 techniques. This is mostly useful for battery powered systems with
1983 APM compliant BIOSes. If you say Y here, the system time will be
1984 reset after a RESUME operation, the /proc/apm device will provide
1985 battery status information, and user-space programs will receive
1986 notification of APM "events" (e.g. battery status change).
1987
1988 In order to use APM, you will need supporting software. For location
1989 and more information, read <file:Documentation/pm.txt> and the
1990 Battery Powered Linux mini-HOWTO, available from
1991 <http://www.tldp.org/docs.html#howto>.
1992
1993 This driver does not spin down disk drives (see the hdparm(8)
1994 manpage ("man 8 hdparm") for that), and it doesn't turn off
1995 VESA-compliant "green" monitors.
1996
1997 Generally, if you don't have a battery in your machine, there isn't
1998 much point in using this driver and you should say N. If you get
1999 random kernel OOPSes or reboots that don't seem to be related to
2000 anything, try disabling/enabling this option (or disabling/enabling
2001 APM in your BIOS).
