Alexander, there is aspect I don't understand (you might be explaining
me but I start to doubt again). Here is what we have on x86-64

 - once proceess starts up the kernel provides vDSO area for it
 - if such vdso area intersects with image addresses we
  - remap runtime vdso to a new free address with MAP_FIXED
  - map old vDSO from image to original address then proxify it if needed

how it's different from ARM64?
