This patch adds the necessary glue to provide time namespaces. Things are mainly copied from ARM64. __arch_get_timens_vdso_data() calculates timens vdso data position based on the vdso data position, knowing it is the next page in vvar. This avoids having to redo the mflr/bcl/mflr/mtlr dance to locate the page relative to running code position.
