Instead of making kASLR depend on !HIBERNATION at compile time, allow kaslr to be selectable at boot time (via "kaslr" kernel command line), which will disable hibernation in the kernel. In this way the end user can choose which feature they want more with hibernation continuing to stay enabled by default (no surprises). -Kees
