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

1843 kernel will support. The maximum supported value is 32 for 32-bit
1844 kernel and 64 for 64-bit kernels; the minimum value which makes

1939 help
1940 kexec is a system call that implements the ability to shutdown your
1941 current kernel, and to start another kernel. It is like a reboot
1942 but it is indepedent of the system firmware. And like a reboot
1943 you can start any kernel with it, not just Linux.
1944
1945 The name comes from the similiarity to the exec system call.
1946
1947 It is an ongoing process to be certain the hardware in a machine
1948 is properly shutdown, so do not be surprised if this code does not
1949 initially work for you. It may help to enable device hotplugging
1950 support. As of this writing the exact hardware interface is
1951 strongly in flux, so no good recommendation can be made.

1958 This kernel feature is useful for number crunching applications
1959 that may need to compute untrusted bytecode during their

1961 the process as file descriptors supporting the read/write
1962 syscalls, it's possible to isolate those applications in
1963 their own address space using seccomp. Once seccomp is
1964 enabled via /proc/<pid>/seccomp, it cannot be disabled
1965 and the task is only allowed to execute a few safe syscalls
1966 defined by each seccomp mode.
