[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.
