Why not avoid poking around in dangerous device spaces. We don't have a bitmap to protect /dev/mem either. The problem is similar too, we have many devices with config space beyond the guaranteed bytes that do fatal things that are not driven directly by Linux - eg some bridges have acpi stuff overlapping there.
A non root user can only touch the safe bytes - 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/
