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.
