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

1130 Please make sure to pick the right CPU type. Linux/MIPS is not
1131 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1132 *not* work on R4000 machines and vice versa. However, since most
1133 of the supported machines have an R4000 (or similar) CPU, R4x00
1134 might be a safe bet. If the resulting kernel does not work,
1135 try to recompile with R3000.

1960 This kernel feature is useful for number crunching applications
1961 that may need to compute untrusted bytecode during their
1962 execution. By using pipes or other transports made available to
1963 the process as file descriptors supporting the read/write
1964 syscalls, it's possible to isolate those applications in
1965 their own address space using seccomp. Once seccomp is
1966 enabled via /proc/<pid>/seccomp, it cannot be disabled
1967 and the task is only allowed to execute a few safe syscalls
1968 defined by each seccomp mode.

1979 ---help---
1980 APM is a BIOS specification for saving power using several different
1981 techniques. This is mostly useful for battery powered systems with
1982 APM compliant BIOSes. If you say Y here, the system time will be
1983 reset after a RESUME operation, the /proc/apm device will provide
1984 battery status information, and user-space programs will receive
1985 notification of APM "events" (e.g. battery status change).
1986
1987 In order to use APM, you will need supporting software. For location
1988 and more information, read <file:Documentation/pm.txt> and the
1989 Battery Powered Linux mini-HOWTO, available from
1990 <http://www.tldp.org/docs.html#howto>.
1991
1992 This driver does not spin down disk drives (see the hdparm(8)
1993 manpage ("man 8 hdparm") for that), and it doesn't turn off
1994 VESA-compliant "green" monitors.
1995
1996 Generally, if you don't have a battery in your machine, there isn't
1997 much point in using this driver and you should say N. If you get
1998 random kernel OOPSes or reboots that don't seem to be related to
1999 anything, try disabling/enabling this option (or disabling/enabling
2000 APM in your BIOS).
