That's how I built the list. Most of the other examples you listed are obviously 64bit... there should be more occurances, but I guess they've (alpha, for instance) not updated their defconfig in a dogs age. Anyway, sorry I didn't notice ARM. I'll add it to the list on the next round. Regards, Kyle (but seriously, this should be select-ed, not just set in a defconfig somewhere...) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
