From b06babac45e1546dfb504f1f25eb0495632bfc41 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Tue, 26 Sep 2006 10:52:29 +0200 Subject: [PATCH] [PATCH] Add proper alignment to ENTRY Previously it didn't align. Use the same one as the C compiler in blended mode, which is good for K8 and Core2 and doesn't hurt on P4.
