|  | 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 | 
|  | strongly in flux, so no good recommendation can be made. |

|  | default y | 
|  | help | 
|  | This kernel feature is useful for number crunching applications | 
|  | that may need to compute untrusted bytecode during their | 
|  | 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. |
