For 32 bit Linux, the virtual memory layout of a process:

Kernel Virtual Memory Address Range: 0xc0000000 - 0xffffffff

Process Virtual Memory Address Range: 0x00000000 - 0xbfffffff

	Process specific data structures (Different for each process)
	Physical memory (Identical for each process)
0xc0000000 ___	Kernel code and data (Identical for each process)
	User stack
	(Unmapped)
	Memory mapped region for shared libraries
brk ___	(Unmapped)
	Run-time heap (via malloc)
	Uninitalized data (.bss)
	Initialized data (.data)
0x08048000__	Program text (.text)
0x00000000___	(Unmapped)

How can multiple process ALL exist with their program text, stack, etc. at the same virtual addresses?
