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,

1218 Please make sure to pick the right CPU type. Linux/MIPS is not
1219 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1220 *not* work on R4000 machines and vice versa. However, since most
1221 of the supported machines have an R4000 (or similar) CPU, R4x00
1222 might be a safe bet. If the resulting kernel does not work,
1223 try to recompile with R3000.

1843 This allows you to specify the maximum number of CPUs which this
1844 kernel will support. The maximum supported value is 32 for 32-bit
1845 kernel and 64 for 64-bit kernels; the minimum value which makes
1846 sense is 1 for Qemu (useful only for kernel debugging purposes)
1847 and 2 for all others.
1848
1849 This is purely to save memory - each supported CPU adds
1850 approximately eight kilobytes to the kernel image. For best
1851 performance should round up your number of processors to the next
1852 power of two.

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

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.
