This patch splits the file arch/x86/vdso-pie.c into machine-dependent and machine-independent parts by moving the routines vdso_fill_symtable(), vdso_proxify(), and vdso_remap() to the file pie/vdso.c. The ARM version of the routines is moved to the source pie/vdso-stub.c to provide the vDSO proxy stub implementation for architectures that don't provide the vDSO.
