Re: [RFC 0/3] Put vdso in ramfs-like filesystem (vdsofs)

The more I'm thinking about this, why don't we simply have these (the
various possible vdsos as well as vvar) as actual files in sysfs instead
of introducing a new filesystem? I don't believe sysfs actually has to
be mounted in order for sysfs files to have an inode.

It could also be in procfs, I guess, but sysfs probably makes more sense.

I'm thinking something like:

/sys/kernel/vdso/{i386,x86_64,x32,vvar}

Not only would this let the container people and so on do weird things
much easier, but it ought to eliminate a whole slew of special cases.
