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

1132 Please make sure to pick the right CPU type. Linux/MIPS is not
1133 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1134 *not* work on R4000 machines and vice versa. However, since most
1135 of the supported machines have an R4000 (or similar) CPU, R4x00
1136 might be a safe bet. If the resulting kernel does not work,
1137 try to recompile with R3000.

1907 32-bit ELF format can optionally be used resulting in a somewhat
1908 smaller binary, but this option is not explicitly supported by the
1909 toolchain and since binutils 2.14 it does not even work at all.

1911 Say Y to use the 64-bit format or N to use the 32-bit one.

1962 This kernel feature is useful for number crunching applications
1963 that may need to compute untrusted bytecode during their
1964 execution. By using pipes or other transports made available to
1965 the process as file descriptors supporting the read/write
1966 syscalls, it's possible to isolate those applications in
1967 their own address space using seccomp. Once seccomp is
1968 enabled via /proc/<pid>/seccomp, it cannot be disabled
1969 and the task is only allowed to execute a few safe syscalls
1970 defined by each seccomp mode.

1981 ---help---
1982 APM is a BIOS specification for saving power using several different
1983 techniques. This is mostly useful for battery powered systems with
1984 APM compliant BIOSes. If you say Y here, the system time will be
1985 reset after a RESUME operation, the /proc/apm device will provide
1986 battery status information, and user-space programs will receive
1987 notification of APM "events" (e.g. battery status change).
1988
1989 In order to use APM, you will need supporting software. For location
1990 and more information, read <file:Documentation/pm.txt> and the
1991 Battery Powered Linux mini-HOWTO, available from
1992 <http://www.tldp.org/docs.html#howto>.
1993
1994 This driver does not spin down disk drives (see the hdparm(8)
1995 manpage ("man 8 hdparm") for that), and it doesn't turn off
1996 VESA-compliant "green" monitors.
1997
1998 Generally, if you don't have a battery in your machine, there isn't
1999 much point in using this driver and you should say N. If you get
2000 random kernel OOPSes or reboots that don't seem to be related to
2001 anything, try disabling/enabling this option (or disabling/enabling
2002 APM in your BIOS).
