Can anyone summarize what all are being changed in the virtual address space of a 64-bit process. I know the virtual address space of 32-bit process is divided into 3G/1G.

   .  ------------------------. 0xFFFFFFFF 
      |                        | (4 GB) 
      |    Kernel addresses    | 
      |                        | 
      |                        | 
      .------------------------.CONFIG_PAGE_OFFSET 
      |                        |(x86: 0xC0000000, ARM: 0x80000000) 
      |                        | 
      |                        | 
      |  User space addresses  | 
      |                        | 
      |                        | 
      |                        | 
      |                        | 
      '------------------------' 00000000
