Checkpoint/Restore In Userspace (CRIU) needs to be able to unmap and remap the VDSO to successfully checkpoint and restore applications in the face of changing VDSO addresses due to Address Space Layout Randomization (ASLR, randmaps). Previously, this was implemented in architecture-specific code for PowerPC and x86. However, a generic version based on Laurent Dufour's PowerPC implementation is now available, so begin using it on ARM.
