Can anyone give pointers as to how memory management(detailed) is done in
linux on powerpc.

by pointers i meant any documentation of design as to how exactly the memory
management is done...
how does linux use hardware features provided by powerpc for protection
between tasks and kernel,etc...
sorry for not being more specific previously...

Sumedh.

It depends on what platform you want to look at, powerpc64, powerpc32 classic
and powerpc32 book E are very different, but you'll see that in the code.
arch/powerpc/mm/hash*
arch/powerpc/mm/pgtable*
arch/powerpc/mm/mem.c
arch/powerpc/mm/ppc_mmu_32.c
arch/powerpc/mm/slb*
arch/powerpc/mm/stab.c
arch/powerpc/mm/tlb*
include/asm-powerpc/mmu*
include/asm-powerpc/pgalloc*
include/asm-powerpc/pgtable*
That should cover all you need to know.
