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."

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

2013-06-27netlink: 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. This was spotted by trinity: [ 894.990671] BUG: unable to handle kernel paging request at ffffc9000047b001 [ 894.991034] IP: [<ffffffff81a212c4>] skb_clone+0x24/0xc0 [...] [ 894.991034] Call Trace: [ 894.991034] [<ffffffff81ad299a>] nl_fib_input+0x6a/0x240 [ 894.991034] [<ffffffff81c3b7e6>] ? _raw_read_unlock+0x26/0x40 [ 894.991034] [<ffffffff81a5f189>] netlink_unicast+0x169/0x1e0 [ 894.991034] [<ffffffff81a601e1>] netlink_sendmsg+0x251/0x3d0 Fix it by: 1) introducing a new netlink_skb_clone function that is used in nl_fib_input, that sets our special skb->destructor 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.

2013-06-27sit: add support of x-netnsNicolas Dichtel
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. Once the tunnel is found, the packet is decapsulated and injecting into the corresponding interface which stands to another netns. When one of the two netns is removed, the tunnel is destroyed.

2013-06-27cgroup: CGRP_ROOT_SUBSYS_BOUND should be ignored when comparing mount optionsTejun Heo
1672d04070 ("cgroup: fix cgroupfs_root early destruction path") introduced CGRP_ROOT_SUBSYS_BOUND which is used to mark completion of subsys binding on a new root; however, this broke remounts. cgroup_remount() doesn't allow changing root options via remount and CGRP_ROOT_SUBSYS_BOUND, which is set on all fully initialized roots, makes the function reject all remounts. Fix it by putting the options part in the lower 16 bits of root->flags and masking the comparions. While at it, make cgroup_remount() emit an error message explaining why it's rejecting a remount request, so that it's less of a mystery. Signed-off-by: Tejun Heo <tj@kernel.org>

2013-06-28drm/ttm: convert to the reservation apiMaarten Lankhorst
Now that the code is compatible in semantics, flip the switch. Use ww_mutex instead of the homegrown implementation. ww_mutex uses -EDEADLK to signal that the caller has to back off, and -EALREADY to indicate this buffer is already held by the caller. ttm used -EAGAIN and -EDEADLK for those, respectively. So some changes were needed to handle this correctly.

2013-06-28reservation: cross-device reservation support, v4Maarten Lankhorst
This adds support for a generic reservations framework that can be hooked up to ttm and dma-buf and allows easy sharing of reservations across devices. The idea is that a dma-buf and ttm object both will get a pointer to a struct reservation_object, which has to be reserved before anything is done with the contents of the dma-buf. Changes since v1: - Fix locking issue in ticket_reserve, which could cause mutex_unlock to be called too many times. Changes since v2: - All fence related calls and members have been taken out for now, what's left is the bare minimum to be useful for ttm locking conversion. Changes since v3: - Removed helper functions too. The documentation has an example implementation for locking. With the move to ww_mutex there is no need to have much logic any more.

2013-06-28drm: add hotspot support for cursors.Dave Airlie
So it looks like for virtual hw cursors on QXL we need to inform the "hw" device what the cursor hotspot parameters are. This makes sense if you think the host has to draw the cursor and interpret clicks from it. However the current modesetting interface doesn't support passing the hotspot information from userspace. This implements a new cursor ioctl, that takes the hotspot info as well, userspace can try calling the new interface and if it gets -ENOSYS it means its on an older kernel and can just fallback.

Whenever we are changing frequency of a cpu, we are calling PRECHANGE and POSTCHANGE notifiers. They must be serialized. i.e. PRECHANGE or POSTCHANGE shouldn't be called twice contiguously.

MMC_CAP2_POWEROFF_NOTIFY is replaced by MMC_CAP2_FULL_PWR_CYCLE, since it makes sense to use a wider scope for it.

Considering shutdown of the card, the responsibility to initate this sequence shall be driven from the mmc_bus. This patch enables the mmc_bus to handle this sequence properly.

2013-06-27drm: kms_helper: don't lose hotplug eventDaniel Vetter
There's a race window (small for hpd, 10s large for polled outputs) where userspace could sneak in with an unrelated connnector probe ioctl call and eat the hotplug event (since neither the hpd nor the poll code see a state change). To avoid this, check whether the connector state changes in all other ->detect calls (in the current helper code that's only probe_single) and if that's the case, fire off a hotplug event. Note that we can't directly call the hotplug event handler, since that expects that no locks are held (due to reentrancy with the fb code to update the kms console). Also, this requires that drivers using the probe_single helper function set up the poll work. All current drivers do that already, and with the reworked hpd handling there'll be no downside to unconditionally setting up the poll work any more.

2013-06-27input: document gamepad API and add extra keycodesDavid Herrmann
Until today all gamepad input drivers report their data differently. It is nearly impossible to write applications for more than one device in a generic way. Therefore, this patch introduces a uniform gamepad API which will be used for all new drivers. Instead of mapping buttons by their labels, we now map them by position. This allows applications to work with any gamepad regardless of the labels on the buttons. Furthermore, we standardize the ABS_* codes for analog triggers and sticks. For D-Pads the long overdue BTN_DPAD_* codes are introduced. They should be fairly obvious how to use. To avoid confusion, the action buttons now have BTN_EAST/SOUTH/WEST/NORTH aliases.
