vdso and shared page patch

[Giuseppe Cocomazzi]

Hi,
I've written a huge patch which implements vdso support and shared page 
subsystem for freebsd. Unfortunately, I've been waiting for a review
for quite a long time and, after some positive responses, silence 
overcame, so the code became a bit old, also due to my difficulty in 
keeping the source up-to-date.
I understand that now it is very unlikely for the patch to be seriously 
considered, however I provide the links to the code and a little 
explanatory paper, in case someone is interested:

patch:  http://sbudella.altervista.org/stuff/shared_page_vdso.patch
paper: http://sbudella.altervista.org/stuff/shared_page_vdso.note
tgz: http://sbudella.altervista.org/stuff/shared_page_vdso.tgz

Feedback would be very appreciated.
Thanks for your attention,

Giuseppe Cocomazzi
