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 Please make sure to pick the right CPU type. Linux/MIPS is not
1128 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

1130 of the supported machines have an R4000 (or similar) CPU, R4x00
1131 might be a safe bet. If the resulting kernel does not work,

1954 help
1955 This kernel feature is useful for number crunching applications
1956 that may need to compute untrusted bytecode during their
1957 execution. By using pipes or other transports made available to
1958 the process as file descriptors supporting the read/write
1959 syscalls, it's possible to isolate those applications in
1960 their own address space using seccomp. Once seccomp is
1961 enabled via /proc/<pid>/seccomp, it cannot be disabled
1962 and the task is only allowed to execute a few safe syscalls
1963 defined by each seccomp mode.
1964
1965 If unsure, say Y. Only embedded should say N here.

1974 ---help---
1975 APM is a BIOS specification for saving power using several different
1976 techniques. This is mostly useful for battery powered systems with
1977 APM compliant BIOSes. If you say Y here, the system time will be
1978 reset after a RESUME operation, the /proc/apm device will provide
1979 battery status information, and user-space programs will receive
1980 notification of APM "events" (e.g. battery status change).
1981
1982 In order to use APM, you will need supporting software. For location
1983 and more information, read <file:Documentation/pm.txt> and the
1984 Battery Powered Linux mini-HOWTO, available from
1985 <http://www.tldp.org/docs.html#howto>.
1986
1987 This driver does not spin down disk drives (see the hdparm(8)
1988 manpage ("man 8 hdparm") for that), and it doesn't turn off
1989 VESA-compliant "green" monitors.
1990
1991 Generally, if you don't have a battery in your machine, there isn't
1992 much point in using this driver and you should say N. If you get
1993 random kernel OOPSes or reboots that don't seem to be related to
1994 anything, try disabling/enabling this option (or disabling/enabling
1995 APM in your BIOS).
