From 4ee189a9260849ebacbdd3caf1fd5eb077fcf6a9 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Wed, 11 Jan 2006 12:17:23 -0800 Subject: [PATCH] uml: fix missing KBUILD_BASENAME 2.6.15-mm1 caused kernel-offsets.c to stop compiling with a syntax error in a header. The problem was with KBUILD_BASENAME, which didn't get a definition with the by-hand compilation in the main UML Makefile. This was OK before since the expansion was syntactically the same as the KBUILD_BASENAME token. With -mm1, the expansion is now a quote-delimited string, so there needs to be a definition of it. Since kernel-offsets.c is basically the same as other arches' asm-offsets.c, and those seem to build OK, this patch turns kernel-offsets.c into asm-offsets.c. kernel-offsets.c is in arch/um/sys-$(SUBARCH), i.e. sys-i386 and sys-x86_64, while kbuild expects it to be in arch/um/kernel. kernel-offsets.c is moved to arch/um/include/sysdep-$(SUBARCH)/kernel-offsets.h, which is included by arch/um/kernel/asm-offsets.c. With that, include/asm-um/asm-offsets.h is generated automatically. kernel-offsets.h continues to exist because it needs to be accessible to userspace UML code, and include/asm-um isn't. So, a symlink is made from arch/um/include/kernel-offsets.h to include/asm-um/asm-offsets.h.
