    Kernel: remove kexex/kdump
    
    - Rarely used and a bit difficult to setup
    - Console messages should help in most cases anyway.
    - Taking time to explain during a course
    
    Don't hesitate to revert if you don't agree

-    \item \code{kexec} system call: makes it possible to call a new
-      kernel, without rebooting and going through the BIOS / firmware.
-    \item Idea: after a kernel panic, make the kernel automatically
-      execute a new, clean kernel from a reserved location in RAM, to
-      perform post-mortem analysis of the memory of the crashed
-      kernel.
-    \item See \kerneldoc{kdump/kdump.txt} in the kernel
-      sources for details.
