From b82fef82d56789439e6be638a87a1a5bba1e6e75 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Wed, 9 Feb 2011 08:24:34 +0000 Subject: x86: Partly unify asm-offsets_{32,64}.c Just consolidating the common parts. Full unification would seem straight forward, but it's not clear the necessary #ifdef-s would be acceptable.
