in this URL:
http://unix.stackexchange.com/questions/32244/user-kernel-split-in-64bit-linux

it says user space get 128 TiB...the rest you can read  there :)

sure.... just change PAGE_OFFSET if I remember correctly...however,
the effects might be harmful, for example for certain virtualization
since they assume certain address for memory allocation

kernel..for sure..
