FWIW, hpa has picked up the vmcoreinfo change and is going to try to
push it for 3.14.

[PATCH v2] x86, kaslr: randomize module base load address
https://lkml.org/lkml/2014/2/25/630
Although it only seems like it bumps up the minimum base address
for the modules virtual address region?
Right, this just "skips" a random chunk of memory at the start of the
module area. I don't expect this to break anything, though.
