I will address the compat VDSO issue.

But the VVAR macro will be not a part of this patch set. If you depend
on this, feel free to create one. From my point of view this is not
feasible without a macro hacking, because the address accessing the vvar
area differs in kernel and VDSO user mode.

I also see no redundant mapping. There are two modes, one is the map of
the kernel area the other maps the VDSO into the user space area. This
is exactly the behaviour of the origin VDSO implementation.

Will do this.
