[NEW-PATCH] exec: allow > 2GB executables to run on 64-bit systems

[Andi Kleen <andi@firstfloor.org>]

Since Dave didn't post an updated patch. This is how I think what
the patch should be. I also changed sys_uselib just to be complete.

----


Always use O_LARGEFILE for opening executables

This allows to use executables >2GB.

Based on a patch by Dave Anderson
