Subject: [PATCH 0/2] make kASLR vs hibernation boot-time selectable

Distros want to be able to offer CONFIG_RANDOMIZE_BASE as well as
CONFIG_HIBERNATION in a single kernel. 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).
