[PATCH] i386: Fix usage of -mtune when X86_GENERIC=y or CONFIG_MCORE2=y

Browse Source 
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
<http://lkml.org/lkml/2007/2/28/230>.
