But not just random garbage, all of the non-zero bytes in the page flags are in visible the ASCII character range. 0x6c = 'l' 0x4b = 'K' 0x6e = 'n' 0x4f = 'O' 0x56 = 'V' Anyways, just FYI... -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
