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

1216 Please make sure to pick the right CPU type. Linux/MIPS is not
1217 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1218 *not* work on R4000 machines and vice versa. However, since most
1219 of the supported machines have an R4000 (or similar) CPU, R4x00
1220 might be a safe bet. If the resulting kernel does not work,
1221 try to recompile with R3000.

1841 This allows you to specify the maximum number of CPUs which this
1842 kernel will support. The maximum supported value is 32 for 32-bit
1843 kernel and 64 for 64-bit kernels; the minimum value which makes
1844 sense is 1 for Qemu (useful only for kernel debugging purposes)
1845 and 2 for all others.
1846
1847 This is purely to save memory - each supported CPU adds
1848 approximately eight kilobytes to the kernel image. For best
1849 performance should round up your number of processors to the next
1850 power of two.

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

1961 syscalls, it's possible to isolate those applications in
1962 their own address space using seccomp. Once seccomp is

1964 and the task is only allowed to execute a few safe syscalls
