Kernel: Let's say that everything < 3GB is user virtual memory

Browse source 
Technically the bottom 2MB is still identity-mapped for the kernel and
not made available to userspace at all, but for simplicity's sake we
can just ignore that and make "address < 0xc0000000" the canonical
check for user/kernel.
