With the current implementation, __cvdso_getrandom_data() calls memset(), which is unexpected in the VDSO. Rewrite opaque data initialisation to avoid memset().
I think of the various ways I've seen of fixing this -- e.g. adding a
memset() arch-by-arch -- this is the cleanest and simplest. I'll add
this as a fix to random.git now.
