If you think anything was "fully driven via the .config alone" you seem to neither understand how it works without my patch nor how it works with my patch. What drives your build without my patch is _not_ the .config but your ARCH=i386. When understand this, you might start understanding why I bang my head against the wall each time a "make" fails on a 64bit .config when I try to reproduce some compile or section mismatch problem someone reported and kconfig automatically forces CONFIG_64BIT=n since I'm on a 32bit computer. Can we please get my patch into 2.6.24 so that we'll get _one_ architecture in kconfig and not the current mess with three different situations in kconfig based on the ARCH setting (and the 32/64bit of your userspace forcing a CONFIG_64BIT setting you have to override with ARCH= on the command line)? > Ingo cu Adrian BTW: The correct way to drive your randconfigs (that is not limited to to 32/64bit) is to use KCONFIG_ALLCONFIG. -- "Is there not promise of rain?"

If the unified x86 architecture should be presented as one architecture in kconfig that's expected - and it might even reduce the amount of 32bit compile errors that recently occured in the git-x86 tree... > Ingo cu Adrian -- "Is there not promise of rain?"
