[PATCH 0/3] Get defconfig to work with ARCH=um

[Ramkumar Ramachandra]

Hi,

  $ ARCH=um make defconfig
  $ ARCH=um make

does not work on 64-bit hosts, because the build-infrastructure is
hard-wired to pick a 32-bit defconfig when ARCH=um.  This series fixes
the problem.

[1/3] is somewhat unrelated to the series, and I happened to notice it
while reading.  12783aa07 (um: Switch to large mcmodel on x86_64,
2012-01-24) indicates that I did something stupid, but I don't know
what.

Thanks.

[PATCH 1/3] arch/um/Makefile: remove dead code

[Ramkumar Ramachandra]

arch/um/Makefile is included in the toplevel Makefile:495.  Well before
that, it unconditionally sets $SUBARCH (in Makefile:168) as follows:

  SUBARCH := $(shell uname -m | sed -e s/i.86/x86/ -e s/x86_64/x86/ \
				    -e s/sun4u/sparc64/ \
				    -e s/arm.*/arm/ -e s/sa110/arm/ \
				    -e s/s390x/s390/ -e s/parisc64/parisc/ \
				    -e s/ppc.*/powerpc/ -e s/mips.*/mips/ \
				    -e s/sh[234].*/sh/ -e s/aarch64.*/arm64/ )

It is clearly impossible for $SUBARCH to be set as i386 or x86_64.
Therefore, any code that checks $SUBARCH against these values is dead
code.

[PATCH 2/3] arch/um/configs: add defconfig for i386, x86_64

[Ramkumar Ramachandra]

arch/um/defconfig only lists one default configuration, and that applies
only to 32-bit architectures.  To prepare the build infrastructure to
teach ARCH=um about 64-bit host architectures, generate two fresh
defconfig files:

  i386_defconfig and x86_64_defconfig

Subsequent commits will remove the old arch/um/defconfig, and point
build scripts to these new files.

[PATCH 3/3] arch/um: migrate to using defconfig in configs/

[Ramkumar Ramachandra]

Remove arch/um/defconfig.  This requires two updates to build scripts:

1. um's Kconfig (arch/x86/um/Kconfig) should specify an ARCH_DEFCONFIG
   section explicitly pointing to these scripts if the required
   variables are set.  Take care to remove the DEFCONFIG_LIST section
   defined in the included file arch/um/Kconfig.common.

2. um's Makefile (arch/um/Makefile) should set KBUILD_DEFCONFIG properly
   for the top-level Makefile to pick up.  Copy the logic in
   arch/x86/Makefile to properly pick the defconfig file depending on
   the actual architecture; except we're working with $SUBARCH here,
   instead of $ARCH.

Now, you can do:

  $ ARCH=um make defconfig
  $ ARCH=um make

from the toplevel directory and successfully build User-Mode Linux.

No.
If you build UML for x86_64 you override SUBARCH.
i.e. make linux ARCH=um SUBARCH=x86_64

Yes, you broke kernel modules on um/x84_64.
Can you please merge 2/3 and 3/3?
Make sure that a series is always bisect-able.

Ah, thanks.  Kindly drop [1/3].

> Can you please merge 2/3 and 3/3?
> Make sure that a series is always bisect-able.

Oh, but it is bisect'able: [2/3] adds two unused files to configs:
i386_defconfig and x86_64_defconfig.  [3/3] removes the original
defconfig and teaches scripts to use the files added in [2/3].  I
split it for readable diffs, but I'll squash them if you prefer that.

RTFM(make); section 9.5 in GNU make info, or the following from POSIX:

[quote]

Macro definitions shall be taken from the following sources, in the following
logical order, before the makefile(s) are read.

   1.  Macros specified on the make utility command line, in the order
specified on the command line. It is unspecified whether the internal macros
defined in Internal Macros are accepted from this source.
   2.  Macros defined by the MAKEFLAGS environment variable, in the order
specified in the environment variable. It is unspecified whether the internal
macros defined in Internal Macros are accepted from this source.
   3.  The contents of the environment, excluding the MAKEFLAGS and SHELL
variables and including the variables with null values.
   4.  Macros defined in the inference rules built into make.

Macro definitions from these sources shall not override macro definitions from
a lower-numbered source. Macro definitions from a single source (for example,
the make utility command line, the MAKEFLAGS environment variable, or the
other environment variables) shall override previous macro definitions from
the same source.

Macros defined in the makefile(s) shall override macro definitions that occur
before them in the makefile(s) and macro definitions from source 4. If the -e
option is not specified, macros defined in the makefile(s) shall override
macro definitions from source 3. Macros defined in the makefile(s) shall not
override macro definitions from source 1 or source 2.

[end quote]

IOW, any make variable (== macro in POSIX quote above) can be explicitly
set in make(1) command line in form name=value and in that case nothing in
makefile(s) can change its value.  It's true for GNU make, it's true for
BSD make and it's been true for historical Unix make since its introduction
in v7.

Thanks Al, the education is much appreciated.  I always thought =
would override it, and ?= was for default value.

?= is a different story - it refuses to override _any_ earlier declarations,
including ones in makefile itself.  GNU make has added it fairly late, BTW -
in 3.77 (1998); BSD make has grown it at some point during the rewrite
Adam de Boor had been doing in late 80s.  NFI whether he'd invented it or
picked it elsewhere - there had been a lot of cross-pollination between the
variants of make(1) all along...
