Hi,
I know very well that memory on 32-bit Linux system is normally split
in following way

First 3GB = user space (High memory)
Last 1GB = kernel space (Low memory)

But I have some questions,

1. How is memory split up on 64-bit architecture
2. Can we override this 3:1 split ?
3. If yes, who can do that user or kernel?

Thanks,
Pritam Bankar
