Move the module_init/module_exit routines and the associated struct comedi_drive to the end of the source.

Pull networking tree from David Miller: 1) ptp_pch driver build broke during this merge window due to missing slab.h header, fix from Geery Uytterhoeven. 2) If ipset passes in a bogus hash table size we crash because the size is not validated properly. Compounding this, gcc-4.7 can miscompile ipset such that even when the user specifies legitimate parameters the tool passes in an out-of-range size to the kernel. Fix from Jozsef Kadlecsik. 3) Users have reported that the netdev watchdog can trigger with pch_gbe devices, and it turns out this is happening because of races in the TX path of the driver leading to the transmitter hanging. Fix from Eric Dumazet, reported and tested by Andy Cress. 4) Novatel USB551L devices match the generic class entries for the cdc ethernet USB driver, but they don't work because they have generic descriptors and thus need FLAG_WWAN to function properly. Add the necessary ID table entry to fix this, from Dan Williams. 5) A recursive locking fix in the USBNET driver added a new problem, in that packet list traversal is now racy and we can thus access unlinked SKBs and crash. Avoid this situation by adding some extra state tracking, from Ming Lei. 6) The rtlwifi conversion to asynchronous firmware loading is racy, fix by reordering the probe procedure. From Larry Finger. Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=43187 7) Fix regressions with bluetooth keyboards by notifying userland properly when the security level changes, from Gustavo Padovan. 8) Bluetooth needs to make sure device connected events are emitted before other kinds of events, otherwise userspace will think there is no baseband link yet and therefore abort the sockets associated with that connection. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: netfilter: ipset: fix hash size checking in kernel ptp_pch: Add missing #include <linux/slab.h> pch_gbe: fix transmit races cdc_ether: add Novatel USB551L device IDs for FLAG_WWAN usbnet: fix skb traversing races during unlink(v2) Bluetooth: mgmt: Fix device_connected sending order Bluetooth: notify userspace of security level change rtlwifi: fix for race condition when firmware is cached
2012-05-16arch/tile: apply commit 74fca9da0 to the compat signal handling as wellChris Metcalf
This passes siginfo and mcontext to tilegx32 signal handlers that don't have SA_SIGINFO set just as we have been doing for tilegx64. Cc: stable@vger.kernel.org Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
2012-05-16arch/tile: fix up some issues in calling do_work_pending()Chris Metcalf
First, we were at risk of handling thread-info flags, in particular do_signal(), when returning from kernel space. This could happen after a failed kernel_execve(), or when forking a kernel thread. The fix is to test in do_work_pending() for user_mode() and return immediately if so; we already had this test for one of the flags, so I just hoisted it to the top of the function. Second, if a ptraced process updated the callee-saved registers in the ptregs struct and then processed another thread-info flag, we would overwrite the modifications with the original callee-saved registers. To fix this, we add a register to note if we've already saved the registers once, and skip doing it on additional passes through the loop. To avoid a performance hit from the couple of extra instructions involved, I modified the GET_THREAD_INFO() macro to be guaranteed to be one instruction, then bundled it with adjacent instructions, yielding an overall net savings.

2012-05-16qeth: recognize vlan devices in layer3 modefrank.blaschka@de.ibm.com
The qeth layer3 driver is notified about IP address changes. Changes concerning qeth driven network interfaces have to be forwarded to the OSA-card. This includes IP addresses of VLAN interfaces with a qeth device as base device. Function qeth_l3_verify_vlan_dev() determines if the net_device of the IP event belongs to a vlan device belonging to a qeth device as real device. This function is broken starting with commit 7ff0bcf676f7ed224ce21b58c7858c8e527068b2 , which means IP addresses of VLAN devices are no longer set at the base qeth device.

2012-05-16fq_codel: should use qdisc backlog as thresholdEric Dumazet
codel_should_drop() logic allows a packet being not dropped if queue size is under max packet size. In fq_codel, we have two possible backlogs : The qdisc global one, and the flow local one. The meaningful one for codel_should_drop() should be the global backlog, not the per flow one, so that thin flows can have a non zero drop/mark probability.

The MAC layer provides access control to a shared channel and reliable data delivery. The main functions performed by the MAC sublayer are: association and disassociation, security control, optional star network topology functions, such as beacon generation and Guaranteed Time Slots (GTSs) management, generation of ACK frames (if used), and, finally, application support for the two possible network topologies described in the standard.

Since ramoops was converted to pstore, it has nothing to do with character devices nowadays. Instead, today it is just a RAM backend for pstore. The patch just moves things around. There are a few changes were needed because of the move: 1. Kconfig and Makefiles fixups, of course. 2. In pstore/ram.c we have to play a bit with MODULE_PARAM_PREFIX, this is needed to keep user experience the same as with ramoops driver (i.e. so that ramoops.foo kernel command line arguments would still work).

2012-05-16ramoops: use pstore interfaceKees Cook
Instead of using /dev/mem directly and forcing userspace to know (or extract) where the platform has defined persistent memory, how many slots it has, the sizes, etc, use the common pstore infrastructure to handle Oops gathering and extraction. This presents a much easier to use filesystem-based view to the memory region. This also means that any other tools that are written to understand pstore will automatically be able to process ramoops too.
