How does this compare to the implementations for other architectures?  
What are the points on which the VDSO interfaces vary between 
architectures?  It would seem desirable for the code to be factored so 
that the ARM code only contains the minimal set of things that are 
necessarily ARM-specific (for example, just declaring the ARM-specific 
choices before including architecture-independent files shared by all 
architectures that can get these functions from a VDSO).
