Add kernels/linux-libre-x86_64
With this kernel, on machines with an x86_64 compatible CPU, you can run an i686 userspace with an x86_64 kernel. This for instance enables to use the same i686 rootfs on computers with 32bit and 64bit CPUs, while still being able to take advantage of a 64bit kernel on the machines that supports it. The users will then need to force i686 in pacman.conf like that: [options] Architecture = i686 They will also need to select the right kernel at boot.
