Hi Andrew,

Following a discussion with Linus, here is the implementation of the
kernel/Kconfig.instrumentation removal. The result of the discussion has been
to decide to move the architecture dependent instrumentation menu entries to
arch/Kconfig and enable/disable each option on a per architecture basis with a
Kconfig boolean. I moved the architecture independent instrumentation items to
init/Kconfig.

Mathieu

Puts the content of arch/Kconfig in the "General setup" menu.

I don't think it's a good idea to go back to making it per-architecture,
although that extensive "depends on <list-of-archiectures-here>" might
indicate that there certainly is room for cleanup there.

And I don't think it's wrong keeping it in kernel/Kconfig.xyz per se, I
just think it's wrong to (a) lump the code together when it really doesn't
necessarily need to and (b) show it to users as some kind of choice that
is tied together (whether it then has common code or not).

On the per-architecture side, I do think it would be better to *not* have
internal architecture knowledge in a generic file, and as such a line like

        depends on X86_32 || IA64 || PPC || S390 || SPARC64 || X86_64 || AVR32

really shouldn't exist in a file like kernel/Kconfig.instrumentation.

It would be much better to do

        depends on ARCH_SUPPORTS_KPROBES

in that generic file, and then architectures that do support it would just
have a

        bool ARCH_SUPPORTS_KPROBES
                default y

in *their* architecture files. That would seem to be much more logical,
and is readable both for arch maintainers *and* for people who have no
clue - and don't care - about which architecture is supposed to support
which interface...

Sam Ravnborg:

Stuff it into a new file: arch/Kconfig
We can then extend this file to include all the 'trailing'
Kconfig things that are anyway equal for all ARCHs.

But it should be kept clean - so if we introduce such a file
then we should use ARCH_HAS_whatever in the arch specific Kconfig
files to enable stuff that is not shared.

Ideally architecture should be a Kconfig option (it's not needed before 
config runs, unlike, say HOSTCC.)

That might take some major surgery, though.

I think that's what Sam was going to try to get to.
He said that we need all ARCHes to source "drivers/Kconfig",
so I did cris.  About 5 more ARCHes need conversions.

Changelog:

Actually, I know I gave this as the magic incantation, but now that I see
it, I realize that I should have told you to just use

        config ARCH_SUPPORTS_KPROBES
                def_bool y

instead, which is a bit denser.

We seem to use both kinds of syntax for these things, but this is really
what "def_bool" is there for...

Linus:

On the per-architecture side, I do think it would be better to *not* have
internal architecture knowledge in a generic file, and as such a line like

        depends on X86_32 || IA64 || PPC || S390 || SPARC64 || X86_64 || AVR32

really shouldn't exist in a file like kernel/Kconfig.instrumentation.

It would be much better to do

        depends on ARCH_SUPPORTS_KPROBES

in that generic file, and then architectures that do support it would just
have a

        bool ARCH_SUPPORTS_KPROBES
                default y

in *their* architecture files. That would seem to be much more logical,
and is readable both for arch maintainers *and* for people who have no
clue - and don't care - about which architecture is supposed to support
which interface...

Changelog:

Actually, I know I gave this as the magic incantation, but now that I see
it, I realize that I should have told you to just use

        config ARCH_SUPPORTS_KPROBES
                def_bool y

instead, which is a bit denser.

We seem to use both kinds of syntax for these things, but this is really
what "def_bool" is there for...

[-- Attachment #1: move-kconfig-instrumentation-to-arch.patch --]
[-- Type: text/plain, Size: 15958 bytes --]

Move the instrumentation Kconfig to

arch/Kconfig for architecture dependent options
  - oprofile
  - kprobes

and

init/Kconfig for architecture independent options
  - profiling
  - markers

Remove the "Instrumentation Support" menu. Everything moves to "General setup".
Delete the kernel/Kconfig.instrumentation file.

This one seems to be new, and I can't seem to find ltt/Kconfig
anywhere. Wouldn't it be better to move it to a separate patch?

Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca>:
Yes, it has nothing to do in this patch. I missed this one. This fix should be
folded with "Move Kconfig.instrumentation to arch/Kconfig and init/Kconfig".

Thanks!
