I'm opposed to this based on the principle that the kernel should NOT
be a dumping ground for random code that user-space can and should
implement for itself.  As long as the vdso is correctly formatted ELF,
then parsing it is easy, and the kernel should not care at all if or
how user-space accesses it.

The fact that golang got it wrong is not an argument for moving this
functionality into the kernel.
