Even though you think it is no problem, it becomes a problem when we want to give physical memory information via booting command line but atag because there is a restriction in number of characters in booting command line. I don't understand why larger bank size than the section size is problem. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
