From db569afa4e69ceaf89b3723a8f9cd2846ed09c76 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Wed, 30 Jan 2008 13:32:30 +0100 Subject: [PATCH] x86: unify arch/x86/boot/compressed/Makefile(s) Trivial unification of the two Makefiles. Tested doing a defconfig build for both 32 and 64 bit and no build changes occured. Signed-off-by: Sam Ravnborg Cc: "H.
