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

| config KEXEC |
| bool "Kexec system call (EXPERIMENTAL)" |
| depends on EXPERIMENTAL |
| help |
| kexec is a system call that implements the ability to shutdown your |
| current kernel, and to start another kernel. It is like a reboot |
| but it is independent of the system firmware. And like a reboot |
| you can start any kernel with it, not just Linux. |
| |
| The name comes from the similarity to the exec system call. |
| |
| It is an ongoing process to be certain the hardware in a machine |
| is properly shutdown, so do not be surprised if this code does not |
| initially work for you. It may help to enable device hotplugging |
| support. As of this writing the exact hardware interface is |

| help |
| This kernel feature is useful for number crunching applications |

| execution. By using pipes or other transports made available to |
| the process as file descriptors supporting the read/write |
| syscalls, it's possible to isolate those applications in |
| their own address space using seccomp. Once seccomp is |
| enabled via /proc/<pid>/seccomp, it cannot be disabled |
| and the task is only allowed to execute a few safe syscalls |
| defined by each seccomp mode. |
| |
| If unsure, say Y. Only embedded should say N here. |
