The Bovet and Cesati book has a whole chapter on Process Address Space. A 
process's address range is limited by the TASK_SIZE variable (0xC0000000 for 
x86). A nice description of how the address space is layed out along with a 
discussion of malloc's limitations can be found in the lkml archives for July:
