------------------------------------------------------
Subject: Add remove_memory() for ppc64
From: Badari Pulavarty <pbadari@xxxxxxxxxx>
Supply arch specific remove_memory() for PPC64. There is nothing ppc specific
code here and its exactly same as ia64 version. For now, lets keep it arch
specific - so each arch can add its own special things if needed.
