The practical question here is if we already have all of the 
relocation logic for the VDSO why do we need to add more?

The kernel doesn't normally ever relocate the vdso; [...]

that's what is the case right now, but much of the intention behind the 
vma based vDSO is to enable per-process randomized vdso locations, and 
various distributions do that. So the 'modern' vDSO concept is very much 
relocatable.
