Because the s390 version won't set up vdso if it is 0. It is safe to assume that if we are calling special_mapping_restore() then there is a vdso in the checkpoint image, and if that is the case then the checkpointed program was dynamically linked. Other architectures ignore uses_interp so this shouldn't matter to them. Signed-off-by: Serge E.
