From b0b1ff653a0ce88dc9d5cec4e67c9c2be0ba03ef Mon Sep 17 00:00:00 2001 From: Lasse Collin Date: Wed, 2 May 2007 19:27:06 +0200 Subject: [PATCH] [PATCH] i386: Fix usage of -mtune when X86_GENERIC=y or CONFIG_MCORE2=y Hi! I sent this simple patch to lkml about two weeks ago and also cc'ed to Linus, but seems that the patch got ignored. I decided to write to you, because you have modified the relevant file most recently. Below is a copy of the mail that is also available at .
