2013-06-28genirq: Fix can_request_irq() for IRQs without an actionBen Hutchings
Commit 02725e7471b8 ('genirq: Use irq_get/put functions'), inadvertently changed can_request_irq() to return 0 for IRQs that have no action. This causes pcibios_lookup_irq() to select only IRQs that already have an action with IRQF_SHARED set, or to fail if there are none. Change can_request_irq() to return 1 for IRQs that have no action (if the first two conditions are met).

2013-06-28Revert "drm: kms_helper: don't lose hotplug event"Dave Airlie
This reverts commit 160954b7bca43da7cd3cfbce310e6df919a8216e. This was rearming the workqueue with a 0 timeout, causing a WARN_ON, and possible loop. Daniel writes: "I've looked a bit into this and I think we need to have a separate work struct for recovering these lost hotplug events since the continuous self-rearming case is a real risk (e.g. if a connector flip-flops all the time). At least I don't see a sane way to block out re-arming with the current code in a simple way. So reverting the offender seems like the right thing and I'll go back to the drawing board for 3.12."

2013-06-28Merge tag 'omapdss-for-3.11-2' of git://gitorious.org/linux-omap-dss2/linux ↵Jean-Christophe PLAGNIOL-VILLARD
into fbdev/for-next OMAP display subsystem changes for 3.11 (part 2/2) This is the second part of OMAP DSS changes for 3.11. This part contains the new DSS device model support. The current OMAP panel drivers use a custom DSS bus, and there's a hard limit of one external display block per video pipeline. In the new DSS device model the devices/drivers are made according to the control bus of the display block, usually platform, i2c or spi. The display blocks can also be chained so that we can have separate drivers for setups with both external encoder and panel. To allow the current board files, which use the old style panels, to function, the old display drivers are left in their current state, and new ones are added to drivers/video/omap2/displays-new/. When the board files have been converted to use the new style panels, we can remove the old code. This is planned to happen in v3.12. Having to support two very different DSS device models makes the driver somewhat confusing in some parts, and prevents us from properly cleaning up some other parts. These cleanups will be done when the old code is removed. The new device model is designed with CDF (Common Display Framework) in mind. While CDF is still under work, the new DSS device model should be much more similar to CDF's model than the old device model, which should make the eventual conversion to CDF much easier.

into fbdev/for-next OMAP display subsystem changes for 3.11 (part 1/2) This is the first part of OMAP DSS changes for 3.11. This part contains fixes, cleanups and reorganizations that are not directly related to the new DSS device model that is added in part 2, although many of the reorganizations are made to make the part 2 possible. There should not be any functional changes visible to the user except the few bug fixes. The main new internal features: - Display (dis)connect support, which allows us to explicitly (dis)connect a whole display pipeline - Panel list, which allows us to operate without the specific DSS bus - Combine omap_dss_output to omap_dss_device, so that we have one generic "entity" for display pipeline blocks

2013-06-27bonding: when cloning a MAC use NET_ADDR_STOLENnikolay@redhat.com
A simple semantic change, when a slave's MAC is cloned by the bond master then set addr_assign_type to NET_ADDR_STOLEN instead of NET_ADDR_SET. Also use bond_set_dev_addr() in BOND_FOM_ACTIVE mode to change the bond's MAC address because the assign_type has to be set properly.

2013-06-27bonding: remove unnecessary dev_addr_from_first membernikolay@redhat.com
In struct bonding there's a member called dev_addr_from_first which is used to denote when the bond dev should clone the first slave's MAC address but since we have netdev's addr_assign_type variable that is not necessary. We clone the first slave's MAC each time we have a random MAC set to the bond device. This has the nice side-effect of also fixing an inconsistency - when the MAC address of the bond dev is set after its creation, but prior to having slaves, it's not kept and the first slave's MAC is cloned. The only way to keep the MAC was to create the bond device with the MAC address set (e.g. through ip link). In all cases if the bond device is left without any slaves - its MAC gets reset to a random one as before. Signed-off-by: Nikolay Aleksandrov <nikolay@redhat.com> Signed-off-by: David S.

2013-06-27bonding: remove unnecessary setup_by_slave membernikolay@redhat.com

2013-06-27netlink: fix splat in skb_clone with large messagesPablo Neira
Since (c05cdb1 netlink: allow large data transfers from user-space), netlink splats if it invokes skb_clone on large netlink skbs since: * skb_shared_info was not correctly initialized. * skb->destructor is not set in the cloned skb.

Moreover, handle the release of the large cloned skb head area in the destructor path. 2) not allowing large skbuffs in the netlink broadcast path. I cannot find any reasonable use of the large data transfer using netlink in that path, moreover this helps to skip extra skb_clone handling. I found two more netlink clients that are cloning the skbs, but they are not in the sendmsg path. Therefore, the sole client cloning that I found seems to be the fib frontend.

This patch allows to switch the netns when packet is encapsulated or decapsulated. In other word, the encapsulated packet is received in a netns, where the lookup is done to find the tunnel.
