Hook up the generic vDSO implementation to the x86 vDSO data page. Since
the existing vDSO infrastructure is heavily based on the timekeeping
functionality, which works over arrays of bases, a new macro is
introduced for vvars that are not arrays.

The vDSO function requires a ChaCha20 implementation that does not write
to the stack, yet can still do an entire ChaCha20 permutation, so
provide this using SSE2, since this is userland code that must work on
all x86-64 processors.

Way more consumable and looks about right.

Good.

Please take your time and
give others a chance to look at this lot before rushing out v11.

That's my plan indeed. Now that the patch is reviewable, I'll let it sit
for a while. In between v10 and v11, my scratch work will be in
<https://git.zx2c4.com/linux-rng/log/?h=vdso>, which is rebased often.

Thanks again for looking this over.

Jason
