Hi Masahiro,
what do you think about the series below, which moves the includes
of all the architecture independ Kconfig files to the top-level
Kconfig instead of duplicating the includes in all architectures?
Note that this only handles the low-hanging fruite, there are a lot
of other bits that should probably be cleaned up to be common,
but those will be not entirely trivial.
Changes since v1:
- add back a remove source statement from arch/arm/Kconfig
- various fixes from Randy
- various UML patches to be able to use the common Kconfig
This moves all the options under a proper menu.
Based on a patch from Randy Dunlap.

2.18.0
Almost all architectures include it. Add a ARCH_NO_PREEMPT symbol to
disable preempt support for alpha, hexagon, non-coldfire m68k and
user mode Linux.

We can handle all not architecture specific UM configuration directly in
the newly added arch/um/Kconfig. Do so by merging the Kconfig.common,
Kconfig.rest and Kconfig.um files into arch/um/Kconfig, and move the main
UML menu as well.

+ possible requests is provided.
+
+ This is the feature normally accomplished by pressing a key
+ while holding SysRq (Alt+PrintScreen).
+
+ On UML, this is accomplished by sending a "sysrq" command with

+ their own address space using seccomp. Once seccomp is
+ enabled via prctl(PR_SET_SECCOMP), it cannot be disabled
+ and the task is only allowed to execute a few safe syscalls
+ defined by each seccomp mode.

-config STATIC_LINK
- bool "Force a static link"

- help
- This option gives you the ability to force a static link of UML.
- Normally, UML is linked as a shared binary. This is inconvenient for
- use in a chroot jail. So, if you intend to run UML inside a chroot,
- you probably want to say Y here.
- Additionally, this option enables using higher memory spaces (up to

-config HOSTFS

- help
- While the User-Mode Linux port uses its own root file system for
- booting and normal file access, this module lets the UML user
- access files stored on the host. It does not require any
- network connection between the Host and UML. An example use of
- this might be:
-
- mount none /tmp/fromhost -t hostfs -o /tmp/umlshare
-
- where /tmp/fromhost is an empty directory inside UML and
- /tmp/umlshare is a directory on the host with files the UML user
- wishes to access.
-
- For more information, see
- <http://user-mode-linux.sourceforge.net/hostfs.html>.
-
- If you'd like to be able to work with files stored on the host,
- say Y or M here; otherwise say N.
-
-config MCONSOLE
- bool "Management console"
- depends on PROC_FS
- default y
- help
- The user mode linux management console is a low-level interface to
- the kernel, somewhat like the i386 SysRq interface. Since there is
- a full-blown operating system running under every user mode linux
- instance, there is much greater flexibility possible than with the
- SysRq mechanism.
-
- If you answer 'Y' to this option, to use this feature, you need the
- mconsole client (called uml_mconsole) which is present in CVS in
- 2.4.5-9um and later (path /tools/mconsole), and is also in the
- distribution RPM package in 2.4.6 and later.
-
- It is safe to say 'Y' here.
-
-config MAGIC_SYSRQ
- bool "Magic SysRq key"
- depends on MCONSOLE
- help
- If you say Y here, you will have some control over the system even
- if the system crashes for example during kernel debugging (e.g., you
- will be able to flush the buffer cache to disk, reboot the system
- immediately or dump some status information). A key for each of the
- possible requests is provided.
-
- This is the feature normally accomplished by pressing a key
- while holding SysRq (Alt+PrintScreen).
-
- On UML, this is accomplished by sending a "sysrq" command with
- mconsole, followed by the letter for the requested command.

- ---help---
- This kernel feature is useful for number crunching applications
- that may need to compute untrusted bytecode during their
- execution. By using pipes or other transports made available to
- the process as file descriptors supporting the read/write
- syscalls, it's possible to isolate those applications in
- their own address space using seccomp. Once seccomp is
- enabled via prctl(PR_SET_SECCOMP), it cannot be disabled
- and the task is only allowed to execute a few safe syscalls
- defined by each seccomp mode.
-
- If unsure, say Y.

2.18.0
Move the source of lib/Kconfig.debug and arch/$(ARCH)/Kconfig.debug to
the top-level Kconfig. For two architectures that means moving their
arch-specific symbols in that menu into a new arch Kconfig.debug file,
and for a few more creating a dummy file so that we can include it
unconditionally.
Also move the actual 'Kernel hacking' menu to lib/Kconfig.debug, where
it belongs.

Instead of duplicating the source statements in every architecture just
do it once in the toplevel Kconfig file.
Note that with this the inclusion of arch/$(SRCARCH/Kconfig moves out of
the top-level Kconfig into arch/Kconfig so that don't violate ordering
constraits while keeping a sensible menu structure.

Put everything in arch/Kconfig into a General options menu
so that they don't clutter up the main/major/primary list of

Merge arch/um/Kconfig.char and arch/um/Kconfig.net into a new
arch/um/drivers/Kconfig. This fits the way Kconfig files are placed
elsewhere in the kernel tree.

I noticed at least sh is broken
because "arch/sh/mm/Kconfig" is no longer included by anyone.
I am not doing further tests.
Please test *ALL* architectures.
If possible, matrix tests (arch, config-target), where
arch = arm, arm64, ...
config-target = allyesconfig, allnoconfig, alldefconfig, ...
Note:
scripts/diffconf is helpful.

Hi,
Thanks for noticing that.
I have tested all $ARCH (except um) with "allmodconfig" and so far, arch/sh/
is the only one that has a problem.

Well, there are 3 $ARCH-es that have an arch/$ARCH/mm/Kconfig file:
arm, sh, and unicore32.
We can either merge those into arch/$ARCH/Kconfig or we can source
arch/$ARCH/mm/Kconfig for all $ARCH (where most of these files will be
empty).
Christoph, thoughts/ideas?

The first option (merge into arch/$ARCH/Kconfig) is not a good option.
Some of these mm/Kconfig files are Large, so the second option is the only
one that makes sense to me.

All that *should* be needed is to add
source arch/sh/mm/Kconfig into arch/sh/Kconfig (as is done in arm and unicore32),
but that causes lots of .config diffs (as seen by scripts/diffconfig).
and I can't work on this any more tonight. :)

I'm a little busy right now, I'll got back to fix sh and retest in a few
days hopefully.

I'd say lets keep them for now, not good reason to change any of
this stuff.

For defconfig:
All $ARCH look equivalent except for microblaze and nios2.
For those, the config SWAP in init/Kconfig (line 221) comes before (and
hence takes precedence) over arch/$(SRCARCH)/Kconfig settings, which is
def_bool n for both microblaze and nios2.

Both of those are NOMMU architectures, so the default SWAP
decaration should do the right thing.
I wish the kconfig tools could warn about duplicate symbols, as they
are basically always bogus or at least very problematic.
I've update the kconfig-cleanup branch in git with the fixes, but
I didn't have time to do anything but a trivial x86 test yet.
