Hi Andi,

I tried playing with your vdso patch.  I'm curious 
what magic is needed to make an application link with
the vdso?  

You also mentioned that there are problems with newer
tool chains.  I think I'm seeing this problem when I
build on an FC6 system.  The ends up using
file offsets like 00100120 so it doesn't fit in a 
single page.  This seems to be sensitive to the 
VDSO_PRELINK address.  If I changes this address to
0xffffffffff800000 then the looks correct.
Is this change safe?  Is it enough to change the 
VDSO_PRELINK define or are there other values which 
need to be kept in sync?
