From daa93fab824f2b8c35bd11670c7fab2f32b2de5f Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Mon, 12 Nov 2007 20:54:30 +0100 Subject: [PATCH] x86: enable "make ARCH=x86" After unification of the Kconfig files and introducing K64BIT support in kconfig it required only trivial changes to enable "make ARCH=x86". With this patch you can build for x86_64 in several ways: 1) make ARCH=x86_64 2) make ARCH=x86 K64BIT=y 3) make ARCH=x86 menuconfig => select 64-bit Likewise for i386 with the addition that i386 is default is you say ARCH=x86.
