We could also put the uname info (modulo nodename) into the vDSO.

Or even better: real topology information.

AND rather than OR would be even better.  So glibc could find kernel

Wouldn't it make more sense for this to be in ELF tags, rather than the vdso? Another alternative, I guess, would be to put a pointer in the ELF tags, which may point into the vdso.
