From b48ee7135230ac43b6820d59a784ac0bd51ae552 Mon Sep 17 00:00:00 2001 From: Glauber Costa Date: Tue, 25 Mar 2008 18:36:35 -0300 Subject: [PATCH] x86: align to clflush size Do it instead of using the conservative approach we're currently doing. This is the way x86_64 does, and this patch makes this piece of code the same between them, ready to be integrated.
