ipmi: change device node ordering to reflect probe order
upstream commit: abd24df828f1a72971db29d1b74fefae104ea9e2 In 2.6.14 a patch was merged which switching the order of the ipmi device naming from in-order-of-discovery over to reverse-order-of-discovery. So on systems with multiple BMC interfaces, the ipmi device names are being created in reverse order relative to how they are discovered on the system (e.g. on an IBM x3950 multinode server with N nodes, the device name for the BMC in the first node is /dev/ipmiN-1 and the device name for the BMC in the last node is /dev/ipmi0, etc.). The problem is caused by the list handling routines chosen in dmi_scan.c. Using list_add() causes the multiple ipmi devices to be added to the device list using a stack-paradigm and so the ipmi driver subsequently pulls them off during initialization in LIFO order. This patch changes the dmi_save_ipmi_device() list handling paradigm to a queue, thereby allowing the ipmi driver to build the ipmi device names in the order in which they are found on the system.
