[RFC: 2.6 patch] let MAGIC_SYSRQ no longer depend on DEBUG_KERNEL

From: Adrian Bunk
Date: Tue Nov 22 2005 - 13:56:48 EST


I know several people using MAGIC_SYSRQ not for kernel debugging but for
trying to do a halfway normal shutdown in case of problems.

Since there's no technical reason why MAGIC_SYSRQ would have to depend
on DEBUG_KERNEL, I'm therefore suggesting to drop this dependency.
