Yep. The mem= option can exclude stuff. Alternatively you can patch arch/i386/kernel/mm/init.c:mem_init() to skip that page. - 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/
