912 This is useful for kernel debugging when your machine crashes very
913 early before the console code is initialized. For normal operation
914 it is not recommended because it looks on some machines ugly and

1215 Please make sure to pick the right CPU type. Linux/MIPS is not
1216 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1217 *not* work on R4000 machines and vice versa. However, since most
1218 of the supported machines have an R4000 (or similar) CPU, R4x00
1219 might be a safe bet. If the resulting kernel does not work,
1220 try to recompile with R3000.

1840 This allows you to specify the maximum number of CPUs which this
1841 kernel will support. The maximum supported value is 32 for 32-bit
1842 kernel and 64 for 64-bit kernels; the minimum value which makes
1843 sense is 1 for Qemu (useful only for kernel debugging purposes)
1844 and 2 for all others.
1845
1846 This is purely to save memory - each supported CPU adds
1847 approximately eight kilobytes to the kernel image. For best
1848 performance should round up your number of processors to the next
1849 power of two.

1938 kexec is a system call that implements the ability to shutdown your
1939 current kernel, and to start another kernel. It is like a reboot
1940 but it is indepedent of the system firmware. And like a reboot
1941 you can start any kernel with it, not just Linux.
1942
1943 The name comes from the similiarity to the exec system call.
1944
1945 It is an ongoing process to be certain the hardware in a machine
1946 is properly shutdown, so do not be surprised if this code does not
1947 initially work for you. It may help to enable device hotplugging
1948 support. As of this writing the exact hardware interface is
1949 strongly in flux, so no good recommendation can be made.

1956 This kernel feature is useful for number crunching applications

1959 the process as file descriptors supporting the read/write
1960 syscalls, it's possible to isolate those applications in
1961 their own address space using seccomp. Once seccomp is
1962 enabled via /proc/<pid>/seccomp, it cannot be disabled
1963 and the task is only allowed to execute a few safe syscalls
1964 defined by each seccomp mode.
