The patch titled
     Add remove_memory() for ppc64
has been removed from the -mm tree.  Its filename was
     add-remove_memory-for-ppc64.patch

This patch was dropped because an updated version will be merged

------------------------------------------------------
Subject: Add remove_memory() for ppc64
From: Badari Pulavarty <pbadari@us.ibm.com>

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.
