Log Message:
More ASLR: randomize the kernel main memory. VM_MIN_KERNEL_ADDRESS becomes
variable, and its location is chosen at boot time. There is room for
improvement, since for now we ask for an alignment of NBPD_L4.
This is enabled by default in GENERIC, but not in Xen. Tested extensively
on GENERIC and GENERIC_KASLR, XEN3_DOM0 still boots fine.
