Checkpoint/Restore In Userspace (CRIU) must be able to remap and unmap the
Virtual Dynamic Shared Object (VDSO) to be able to handle the changing
addresses that result from address space layout randomization. Now that the
support for this originally written for PowerPC has been moved to a generic
location and arm64 has adopted unsigned long for the type of mm->context.vdso,
simply opt-in to VDSO unmap and remap support.
