Memory Addressing(Understanding the Linux Kernel)

Linux prefers paging to segmentation for the following reasons:
Memory management is simpler when all processes use the same
segment register values that is, when they share the same set of linear
addresses.
One of the design objectives of Linux is portability to a wide
range of architectures; RISC architectures in particular have limited support
for segmentation.
The 2.6 version of Linux uses segmentation only when required
by the 80 x 86 architecture.
