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

911 This option enables special console drivers which allow the kernel
912 to print messages very early in the bootup process.
913
914 This is useful for kernel debugging when your machine crashes very
915 early before the console code is initialized. For normal operation
916 it is not recommended because it looks on some machines ugly and
917 oesn't cooperate with an X server. You should normally N here,
918 unless you want to debug such a crash.

1940 help
1941 kexec is a system call that implements the ability to shutdown your
1942 current kernel, and to start another kernel. It is like a reboot
1943 but it is indepedent of the system firmware. And like a reboot
1944 you can start any kernel with it, not just Linux.
1945
1946 The name comes from the similiarity to the exec system call.
1947
1948 It is an ongoing process to be certain the hardware in a machine
1949 is properly shutdown, so do not be surprised if this code does not
1950 initially work for you. It may help to enable device hotplugging
1951 support. As of this writing the exact hardware interface is
1952 strongly in flux, so no good recommendation can be made.

1959 This kernel feature is useful for number crunching applications
1960 that may need to compute untrusted bytecode during their

1962 the process as file descriptors supporting the read/write
1963 syscalls, it's possible to isolate those applications in
1964 their own address space using seccomp. Once seccomp is
1965 enabled via /proc/<pid>/seccomp, it cannot be disabled
1966 and the task is only allowed to execute a few safe syscalls
1967 defined by each seccomp mode.
