546 can simulate a MIPS32 4Kc system. This patch adds support for the
547 system architecture that currently is being simulated by Qemu. It
548 will eventually be removed again when Qemu has the capability to
549 simulate actual MIPS hardware platforms. More information on Qemu

907 This option enables special console drivers which allow the kernel
908 to print messages very early in the bootup process.
909
910 This is useful for kernel debugging when your machine crashes very
911 early before the console code is initialized. For normal operation
912 it is not recommended because it looks on some machines ugly and
913 oesn't cooperate with an X server. You should normally N here,

1966 their own address space using seccomp. Once seccomp is
