2013-06-03HID: wiimote: add Classic Controller extensionDavid Herrmann
Add a new extension module for the classic controller so we get hotplug support for this device. It is mostly the same as the old static classic controller parser. Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2013-06-03HID: wiimote: add Nunchuk supportDavid Herrmann
This moves the nunchuk parser over to an extension module. This allows to make use of hotplugged Nunchuks instead of the old static parser. Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2013-06-03HID: wiimote: add Balance Board supportDavid Herrmann
This adds Nintendo Wii Balance Board support to the new HOTPLUG capable wiimote core. It is mostly copied from the old extension. This also adds Balance Board device detection. Whenever we find a device that supports the balance-board extension, we assume that it is a real balance board and disable unsupported hardward like accelerometer, IR, rumble and more.

2013-06-03HID: wiimote: add extension hotplug supportDavid Herrmann
The Wii Remote has several extension ports. The first port (EXT) provides hotplug events whenever an extension is plugged. The second port (MP) does not provide hotplug events by default. Instead, we have to map MP into EXT to get events for it. This patch introduces hotplug support for extensions. It is fairly complicated to get this right because the Wii Remote sends a lot of noise-hotplug events while activating extension ports. We need to filter the events and only handle the events that are real hotplug events. Mapping MP into EXT is easy. But if we want both, MP _and_ EXT at the same time, we need to map MP into EXT and enable a passthrough-mode. This will then send real EXT events through the mapped MP interleaved with real MP events. But once MP is mapped, we no longer have access to the real EXT registers so we need to perform setup _before_ mapping MP. Furthermore, we no longer can read EXT IDs so we cannot verify if EXT is still the same extension that we expect it to be. We deal with this by unmapping MP whenever we got into a situation where EXT might have changed. We then re-read EXT and MP and remap everything. The real Wii Console takes a fairly easy approach: It simply reconnects to the device on hotplug events that it didn't expect. So if a program wants MP events, but MP is disconnected, it fails and reconnects so it can wait for MP hotplug events again. This simplifies hotplugging a lot because we just react on PLUG events and ignore UNPLUG events. The more sophisticated Wii applications avoid reconnection (well, they still reconnect during many weird events, but at least not during UNPLUG) but they start polling the device. This allows them to disable the device, poll for the extension ports to settle and then initialize them again. Unfortunately, this approach fails whenever an extension is replugged while it is initialized. We would loose UNPLUG events and polling the device later will give unreliable results because the extension port might be in some weird state, even though it's actually unplugged. Our approach is a real HOTPLUG approch. We keep track of the EXT and mapped MP hotplug events whenever they occur. We then re-evaluate the device state and initialize any possible new extension or deinitialize any gone extension. Only during initialization, we set an extension port ACTIVE. However, during an unplug event we mark them as INACTIVE. This guarantess that a fast UNPLUG -> PLUG event sequence doesn't keep them marked as PLUGGED+ACTIVE but only PLUGGED. To deal with annoying noise-hotplug events during extension mapping, we simply rescan the device before performing any mapping. This allows us to ignore all the noise events as long as the device is in the correct state. Long story short: EXT and MP registers are sparsely known and we need to jump through hoops to get reliable HOTPLUG working. But while Nintendo needs *FOUR* Bluetooth reconnections for the shortest imaginable boot->menu->game->menu->shutdown sequence, we now need *ZERO*. As always, 3rd party devices tend to break whenever we behave differently than the original Wii. So there are also devices which _expect_ a disconnect after UNPLUG. Obviously, these devices won't benefit from this patch. But all official devices were tested extensively and work great during any hotplug sequence. Yay!

2013-06-03HID: wiimote: convert IR to moduleDavid Herrmann
IR is the last piece that still is handled natively. This patch converts it into a sub-device module like all other sub-devices. It mainly moves code and doesn't change semantics. We also implicitly sync IR data on ir_to_input3 now so the explicit input_sync() calls are no longer needed.

2013-06-03HID: wiimote: convert ACCEL to moduleDavid Herrmann
Accelerometer data is very similar to KEYS handling. Therefore, convert all ACCEL related handling into a sub-device module similar to KEYS. This doesn't change any semantics but only moves code over to wiimote-modules. Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2013-06-03HID: wiimote: convert LEDS to modulesDavid Herrmann
Each of the 4 LEDs may be supported individually by devices. Therefore, we need one module for each device. To avoid code-duplication, we simply pass the LED ID as "arg" argument to the module loading code. This just moves the code over to wiimote-module. The semantics stay the same as before.

2013-06-03HID: wiimote: convert BATTERY to moduleDavid Herrmann

2013-06-03HID: wiimote: convert KEYS and RUMBLE to modulesDavid Herrmann
This introduces the first sub-device modules by converting the KEYS and RUMBLE sub-devices into wiimote modules. Both must be converted at once because they depend on the built-in shared input device. This mostly moves code from wiimote-core to wiimote-modules and doesn't change any semantics or ABI.

2013-06-03HID: wiimote: add sub-device module infrastructureDavid Herrmann
To avoid loading all sub-device drivers for every Wii Remote, even though the required hardware might not be available, we introduce a module layer. The module layer specifies which sub-devices are available on each device-type. After device detection, we only load the modules for the detected device. If module loading fails, we unload everything and mark the device as WIIMOTE_DEV_UNKNOWN. As long as a device is marked as "unknown", no sub-devices will be used and the device is considered unsupported. All the different sub-devices, including KEYS, RUMBLE, BATTERY, LEDS, ACCELEROMETER, IR and more will be ported in follow-up patches to the new module layer.

2013-06-03HID: wiimote: wake up if output queue failedDavid Herrmann
Our output queue is asynchronous but synchronous reports may wait for a response to their request. Therefore, wake them up unconditionally if an output report couldn't be sent. But keep the report ID intact so we don't incorrectly assume our request succeeded. Note that the underlying connection is required to be reliable and does retransmission itself. So it is safe to assume that if the transmission fails, the device is in inconsistent state. Hence, we abort every request if any output report fails. No need to verify which report failed.

2013-06-03HID: wiimote: use cached battery values on I/O failureDavid Herrmann
Battery reports are sent along every status report of the Wii Remote. So chances are pretty high that we have an up-to-date battery cache at any time. Therefore, initialize the battery-cache to 100% and then return battery values from the cache if the query fails. This works around a power_supply limitation in that it requires us to be able to query the device during power_supply registration and removal. Otherwise, "add" or "remove" udev events are not sent. If we answer these requests from our cache instead, we avoid dropping these events and no longer cause warnings printed.

2013-06-03HID: wiimote: add device detectionDavid Herrmann
Nintendo produced many different devices that are internally based on the Wii Remote protocol but provide different peripherals. To support these devices, we need to schedule a device detection during initialization. Device detection includes requesting a status report, reading extension information and then evaluating which device we may be dealing with. We currently detect gen1 and gen2 Wii Remote devices. All other devices are marked as generic devices. More detections will be added later. In followup patches we will be using these device IDs to control which peripherals to initialize. For instance if a device is known to have no IR camera, there is no need to provide the IR input device nor trying to access IR registers. In fact, there are 3rd party devices that break if we try things like this (hurray!). The init_worker will be scheduled whenever we get hotplug events. This isn't implemented, yet and will be added later. However, we need to make sure that this worker can be called multiple times.

2013-06-03HID: wiimote: keep HID device openDavid Herrmann
We need constant I/O to keep the state up-to-date and not miss any packets. Hence, call hid_hw_open() during setup and hid_hw_close() during destruction. These are no-ops for Bluetooth HIDP, but lets be safe. Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2013-06-03HID: wiimote: move queue handling into separate structDavid Herrmann
The output queue is independent of the other wiimote modules and can run on its own. Therefore, move its members into a separate struct so we don't run into name collisions with other modules. This is only a syntactic change that renames all queue members to queue.*. Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2013-06-03HID: wiimote: extend driver descriptionDavid Herrmann
The hid-wiimote driver supports more than the Wii Remote. Nintendo produced many devices based on the Wii Remote, which have extension devices built-in. It is not clear to many users, that these devices have anything in common with the Wii Remote, so fix the driver description. This also updates the copyright information for the coming hotplugging rework. Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

Pull MIPS updates from Ralf Baechle: - More work on DT support for various platforms - Various fixes that were to late to make it straight into 3.9 - Improved platform support, in particular the Netlogic XLR and BCM63xx, and the SEAD3 and Malta eval boards. - Support for several Ralink SOC families. - Complete support for the microMIPS ASE which basically reencodes the existing MIPS32/MIPS64 ISA to use non-constant size instructions. - Some fallout from LTO work which remove old cruft and will generally make the MIPS kernel easier to maintain and resistant to compiler optimization, even in absence of LTO. - KVM support. While MIPS has announced hardware virtualization extensions this KVM extension uses trap and emulate mode for virtualization of MIPS32. More KVM work to add support for VZ hardware virtualizaiton extensions and MIPS64 will probably already be merged for 3.11. Most of this has been sitting in -next for a long time.

2013-05-09ipc,sem: fix semctl(..., GETNCNT)Rik van Riel
The semctl GETNCNT returns the number of semops waiting for the specified semaphore to become nonzero. After commit 9f1bc2c9022c ("ipc,sem: have only one list in struct sem_queue"), the semops waiting on just one semaphore are waiting on that semaphore's list. In order to return the correct count, we have to walk that list too, in addition to the sem_array's list for complex operations.

The kernel crashes while resuming from AFTR idle mode. It happens because L2 cache was not going into retention state.

The biggest exceptions are Josef's skinny extents and Jan Schmidt's code to rebuild our quota indexes if they get out of sync (or you enable quotas on an existing filesystem). The skinny extents are off by default because they are a new variation on the extent allocation tree format. btrfstune -x enables them, and the new format makes the extent allocation tree about 30% smaller. I rebased this a few days ago to rework Dave Sterba's crc checks on the super block, but almost all of these go back to rc6, since I though 3.9 was due any minute. The biggest missing fix is the tracepoint bug that was hit late in 3.9. I ran into problems with that in overnight testing and I'm still tracking it down. I'll definitely have that fixed for rc2." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: (101 commits) Btrfs: allow superblock mismatch from older mkfs btrfs: enhance superblock checks btrfs: fix misleading variable name for flags btrfs: use unsigned long type for extent state bits Btrfs: improve the loop of scrub_stripe btrfs: read entire device info under lock btrfs: remove unused gfp mask parameter from release_extent_buffer callchain btrfs: handle errors returned from get_tree_block_key btrfs: make static code static & remove dead code Btrfs: deal with errors in write_dev_supers Btrfs: remove almost all of the BUG()'s from tree-log.c Btrfs: deal with free space cache errors while replaying log Btrfs: automatic rescan after "quota enable" command Btrfs: rescan for qgroups Btrfs: split btrfs_qgroup_account_ref into four functions Btrfs: allocate new chunks if the space is not enough for global rsv Btrfs: separate sequence numbers for delayed ref tracking and tree mod log btrfs: move leak debug code to functions Btrfs: return free space in cow error path Btrfs: set UUID in root_item for created trees ...
