I see the vdso bits in this series are specific to x86. Do other
architectures need something here?

I might be missing some context; I'm not sure whether that's not
necessary or just not implemented by this series, and so I'm not sure
whether arm64 folk and other need to go dig into this.


If you haven't done it yet, I would like to give a shot to implement the arm64 version of the vDSO.
