From: Paolo 'Blaisorblade' Giarrusso <[EMAIL PROTECTED]>
This config option was lost during the creation of lib/Kconfig.debug, due to a
bad expressed dependency; I also moved the option back to its original place
for UML (it is near CONFIG_MCONSOLE since it depends on that).

+ ---help---
+ If you say Y here, you will have some control over the system even
+ if the system crashes for example during kernel debugging (e.g., you
+ will be able to flush the buffer cache to disk, reboot the system
+ immediately or dump some status information). A key for each of the
+ possible requests is provided.
+
+ This is the feature normally accomplished by pressing a key
+ while holding SysRq (Alt+PrintScreen).
+
+ On UML, this is accomplished by sending a "sysrq" command with
+ mconsole, followed by the letter for the requested command.
+
+ The keys are documented in <file:Documentation/sysrq.txt>. Don't say Y
+ unless you really know what this hack does.
