Instead of duplicating the source statements in every architecture just
do it once in the toplevel Kconfig file.

Hi Christoph,

Looks good overall.  I'm still doing some testing on it.

I would prefer to have init/Kconfig before arch/$(SRCARCH)/Kconfig.
Is there a reason that you chose the ordering above?
Any known dependencies?

Thanks.

Ugh, that won't get this set correctly on x86_64:
CONFIG_PGTABLE_LEVELS=2

I don't think there are and I'll give it a spin.

The series needs a resend due to arm and user mode linux issues the
builtbot found anyway.

Did you try it?  As far as I can tell modern kconfig isn't really
order sensitive any more.

Yes, it was wrong. :(

Once the symbol has a default value, it won't be assigned a different
default value (at least that's how it looks; I haven't read the kconfig
source code).

The order does matter.

The 'default' properties are accumulated
as they appear.


If arch/Kconfig were parsed before arch/x86/Kconfig,
it would end up with this:



config PGTABLE_LEVELS
    int
    default 2                    <- from arch/Kconfig
    default 5 if X86_5LEVEL      <- from arch/x86/Kconfig
    default 4 if X86_64          <- from arch/x86/Kconfig
    default 3 if X86_PAE         <- from arch/x86/Kconfig
    default 2                    <- from arch/x86/Kconfig

So, PGTABLE_LEVELS would be always 2.
The last four lines are dead code.





The correct order is arch/x86/Kconfig, arch/Kconfig
then we can get this:

config PGTABLE_LEVELS
    int
    default 5 if X86_5LEVEL      <- from arch/x86/Kconfig
    default 4 if X86_64          <- from arch/x86/Kconfig
    default 3 if X86_PAE         <- from arch/x86/Kconfig
    default 2                    <- from arch/x86/Kconfig
    default 2                    <- from arch/Kconfig
