linux-next: kbuild tree build failure

Hi Roman.

I thought a bit more about this.

We use Kconfig for a mixture of user editable values and fixed
configuration values.
And I agree that asking the user to input a 64 bit number is not usefull.

But keeping support for 64 bit values is what I would consider
expected functionality.
So removing support for 64 bit is not good IMO.

We use strtol() in a few places in symbol.c already where we do an
implicit conversion to int. Why did this not cause us problems before?

Is it because these code paths are only triggered when we deal with ranges?
If so we could 'fix' strdup_type() to not use strto{,u}l() so it
is 64 bit clean and we are back to old behaviour.
