But I have some questions,
1. How is memory split up on 64-bit architecture
in this URL: http://unix.stackexchange.com/questions/32244/user-kernel-split-in-64bit-lin...
it says user space get 128 TiB...the rest you can read there :)
2. Can we override this 3:1 split ?
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
3. If yes, who can do that user or kernel?
kernel..for sure..

Thanks Mulyadi. I gone through link but there is no explanation. What can be the logic behind kernel space of only 512 MB for 64-bit machines. We have 1GB kernel space in 32-bit architecture so 64-bit should ideally have much more than that. Thanks Pritam Bankar
