kernel: allow features to be used in common-config Signed-off-by: Austin Seipp <aseipp@pobox.com>

Unify the Linux kernel configurations Having N different copies of the NixOS kernel configuration is bad because these copies tend to diverge. For instance, our 3.10 config lacked some modules that were enabled in older configs, probably because the 3.10 config had been copied off an earlier version of some older kernel config. So now there is a single kernel config in common-config.nix. It has a few conditionals to deal with new/removed kernel options, but otherwise it's pretty straightforward. Also, a lot of cut&paste boilerplate between the kernel Nix expressions is gone (such as preConfigure).

nixos: make several kernel common-config options optional Realistically, common-config is useful, but there are a lot of things in there that are non-optionally specified that aren't always useful. For example, when deploying grsecurity, I don't want the bluetooth, wireless, or input joystick/extra filesystem stack (XFS, etc), nor the staging drivers tree. The problem is that if you specify this in your own kernel config in the grsecurity module, by saying 'BT n' to turn off bluetooth, common-config turns on 'BT_HCIUART_BCSP y', which then becomes unused and errors out. This is really just an arbitrary picking at the moment, but it should be OK. Signed-off-by: Austin Seipp <aseipp@pobox.com>

nixos: make several kernel common-config options optional Realistically, common-config is useful, but there are a lot of things in there that are non-optionally specified that aren't always useful. For example, when deploying grsecurity, I don't want the bluetooth, wireless, or input joystick/extra filesystem stack (XFS, etc), nor the staging drivers tree. The problem is that if you specify this in your own kernel config in the grsecurity module, by saying 'BT n' to turn off bluetooth, common-config turns on 'BT_HCIUART_BCSP y', which then becomes unused and errors out. This is really just an arbitrary picking at the moment, but it should be OK. Signed-off-by: Austin Seipp <aseipp@pobox.com>

Unify the Linux kernel configurations Having N different copies of the NixOS kernel configuration is bad because these copies tend to diverge. For instance, our 3.10 config lacked some modules that were enabled in older configs, probably because the 3.10 config had been copied off an earlier version of some older kernel config. So now there is a single kernel config in common-config.nix. It has a few conditionals to deal with new/removed kernel options, but otherwise it's pretty straightforward. Also, a lot of cut&paste boilerplate between the kernel Nix expressions is gone (such as preConfigure).
