TOPDIR is obsolete, use srctree or objtree instead.
This patch set removes all the TOPDIR use in the whole
source tree and finally drops it in the top Makefile.
They're against the current linus-tree.
Note that Patch [8/8] should be applied _after_ all the
previous patches are applied.

Glad to see this being done - long overdue.
Most of your patches (if not all) replaces TOPDIR
with objtree but usage of objtree is only
correct when dealing with output files.
Note that objtree != srctree only for O=... builds.
And a few cases should be dealt with differently.
See individual comments.

Current directory when building is $(objtree) so here we should
just skip the use of TOPDIR like this:

This has never worked with O=.. builds.
The correct fix here is to use:
> + $(CC) -fno-pic $(HEAD_DEFINES) -Iinclude -Iinclude2 -c -o $@ $<
The -Iinclude2 is only for O=... builds so to keep current
behaviour removing $(TOPDIR)/ would do it.

This prerequisite listing looks just bogus and should be removed altogether.
We only need to list prerequisites explicit for generated files.

As in the mips case the right fix is to use:

In this way we pick up the includes also in the O=..
case.

In this file we can just drop use of $(TOPDIR) since this is our

I do not feel confident with these changes.
In some places I had expected to see srctree and not objtree.
I would like to see this tested before applying it.
Building a ppc toolchain now to test it...

It seems that building a ppc based um kernel is not supported
in mainline.
Kconfig.ppc is missing and when creating it um build fails
in sys-ppc/ due to user-offset.c is missing.
As most of your patch touches ppc specific code I suggest
to just replace TOPDIR with srctree all over (no semantic change)
and the the um people can figure out the ppc stuff when they get to it.

You're right. I use srctree instead. And tested with:
$ make O=../foobar/ ARCH=um linux
It works fine. Thanks for your points!

Shouldn't that use $(LINUXINCLUDE), or $(KBUILD_CPPFLAGS)?

FWIW $(TOPDIR) is already banished from the latest xfs build code:
http://oss.sgi.com/cgi-bin/cvsweb.cgi/xfs-linux/Makefile
and the patch is in -mm too via git:
http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.24-rc6/2.6.24-rc6-mm1/broken-out/git-xfs.patch

p.s. what is $(objtree) exactly? I don't see it mentioned in
Documentation/kbuild except as one line in an example... I thought
$(obj) and $(src) should be used outside of the core kbuild
infrastructure, and in this case wouldn't it be $(src) anyway?

You can do this simpler:
+EXTRA_CFLAGS += -I$(src) -I$(src)/linux-2.6 -funsigned-char
+
+XFS_LINUX := linux-2.6
+
+ifeq ($(CONFIG_XFS_DEBUG),y)
+ EXTRA_CFLAGS += -g
+endif
+
like this:
ccflags-y := -I$(src) -I$(src)/linux-2.6 -funsigned-char
ccflags-$(CONFIG_XFS_DEBUG) += -g
XFS_LINUX := linux-2.6

$(objtree) specify the build directory and is only rarely used.
Half of the current users are buggy and I should fix it one day.

This is wrong. s390 have a file named binfmt_elf32.c and with this
change it does no longer build.
If the output file does not exist then kbuild does not care about the
dependencies and will just build the target.
On the second invocation when the target exists then kbuild has
created a file named .<target>.cmd that list the dependencies
and this includes any included .c file.
So there is just no pint in defining this dependency explicit
in the MAkefile - kbuild will figure it out automatically.
The right fix is just to kill the explicit listed dependency.

It would be better to use $(LINUXINCLUDE) as we then pull in all config
symbols too and do not have to hardcode kbuild internal names (include2).
As for the use of KBUILD_CPPFLAGS at present the usage is not consistent
across the architectures. Why does arm for example say:
KBUILD_CPPFLAGS += -mbig-endian
This looks like a KBUILD_CFLAGS thing to me.
So we should preferably stick with LINUXINCLUDE for now.

If I understand you correctly, then the fix should be

This one is correct. I'll add it to git390.

Hi Wang.
You a heads up. I will most likely apply
the remaining of the patches tonight, except the UM stuff
which I hope Jeff to take and the final removal of TOPDIR
may wait a bit.
I want the s390, xfs and um changes to hit -mm at least
and we have several external modules that uses TOPDIR.
And some of these external modules I care about - not
all of them but some of them.

We had the TOPDIR replaced with $(srcdir) already, but this looks better.
Compiles OK for both EtraxFS and ARTPEC-3 cpus in our tree.

As in the mips case the right fix is to use:
> +CC = gcc-cris -mlinux -march=v32 -Iinclude -Iinclude2
In this way we pick up the includes also in the O=..
case.
PS. Mikael - should Jesper be mentioned in MAINTAINERS?

LDSCRIPT also needed fixing to get builds in a separate object directory
working again.

This needs to read:

(There is no difference between src and obj in normal cases but to be consistent
it shuld be like above).
