In 2.4.x kernels MAX_ORDER is 10 and PAGE_SIZE is 4096 on x86 so this limit should be 4MB. MAX_ORDER can be set higher by certain configuration changes, via CONFIG_FORCE_MAX_ZONEORDER. Perhaps it is set to 14 for the kernel you are using. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
