507 Qemu is a software emulator which among other architectures also
508 can simulate a MIPS32 4Kc system. This patch adds support for the
509 system architecture that currently is being simulated by Qemu. It
510 will eventually be removed again when Qemu has the capability to
511 simulate actual MIPS hardware platforms. More information on Qemu
512 can be found at http://www.linux-mips.org/wiki/Qemu.

1127 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

1130 might be a safe bet. If the resulting kernel does not work,

1953 help
1954 This kernel feature is useful for number crunching applications
1955 that may need to compute untrusted bytecode during their
1956 execution. By using pipes or other transports made available to
1957 the process as file descriptors supporting the read/write
1958 syscalls, it's possible to isolate those applications in
1959 their own address space using seccomp. Once seccomp is
1960 enabled via /proc/<pid>/seccomp, it cannot be disabled
1961 and the task is only allowed to execute a few safe syscalls
1962 defined by each seccomp mode.

1973 ---help---
1974 APM is a BIOS specification for saving power using several different
1975 techniques. This is mostly useful for battery powered systems with
1976 APM compliant BIOSes. If you say Y here, the system time will be
1977 reset after a RESUME operation, the /proc/apm device will provide
1978 battery status information, and user-space programs will receive
1979 notification of APM "events" (e.g. battery status change).
1980
1981 In order to use APM, you will need supporting software. For location
1982 and more information, read <file:Documentation/pm.txt> and the
1983 Battery Powered Linux mini-HOWTO, available from
1984 <http://www.tldp.org/docs.html#howto>.
1985
1986 This driver does not spin down disk drives (see the hdparm(8)
1987 manpage ("man 8 hdparm") for that), and it doesn't turn off
1988 VESA-compliant "green" monitors.
1989
1990 Generally, if you don't have a battery in your machine, there isn't
1991 much point in using this driver and you should say N. If you get
1992 random kernel OOPSes or reboots that don't seem to be related to
1993 anything, try disabling/enabling this option (or disabling/enabling
1994 APM in your BIOS).
