* HID: wiimote: Add extension initializersDavid Herrmann2011-11-221-2/+79
| | | | | | | | | The wiimote extension registers are not fully understood, so we always disable all extensions on extension-port events. Then we reinitialize and reidentify them and activate all requested extensions. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

* HID: wiimote: Add extension support stubDavid Herrmann2011-11-225-4/+178
| | | | | | | | | | | | | | | | | | | | | The wiimote supports several extensions. This adds a separate source file which handles all extensions and can be disabled at compile-time. The driver reacts on "plug"-events on the extension port and starts a worker which initializes or deinitializes the extensions. Currently, the initialization logic is not fully understood and we can only detect and enable all extensions when all extensions are deactivated. Therefore, we need to disable all extensions, then detect and activate them again to react on "plug"-events. However, deactivating extensions will generate a new "plug"-event and we will never leave that loop. Hence, we only support extensions if they are plugged before the wiimote is connected (or before the ext-input device is opened). In the future we may support full extension hotplug support, but reverse-engineering this may take a while.

| | | | | | | | | Extension and sound support for the wiimote are quite complex and will be implemented in separate source files. Hence rename the current driver to "-core" suffix so multiple files can be linked into this module.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 0db3bfc72adf0c (""HID: multitouch: decide if hid-multitouch needs to handle mt devices"). The generic detection of hid-mt devices has two major flaws, and was merged prematurely. Firstly, the hid-multitouch gets loaded even when the device is handled by a special device. Secondly, the patch only partially duplicates the device whitelist already present in hid-core, effectively rendering a number of devices non-functional.

The mutex_lock is thus moved after the NULL test. New error handling labels are added at the end to differentiate between the cases where different sets of locks should be unlocks, and between whether or not reader should be freed (only on error).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When devices in a RAID array are not in-sync, they are supposed to be reported as such in the status output as an 'a' character, which means "alive, but not in-sync". But when the entire array is rebuilt 'A' is being used, which is incorrect. This patch corrects this to 'a'.

| * | dm log userspace: add log device dependencyJonathan E Brassow2011-10-311-3/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow userspace dm log implementations to register their log device so it is no longer missing from the list of device dependencies. When device mapper targets use a device they normally call dm_get_device which includes it in the device list returned to userspace applications such as LVM through the DM_TABLE_DEPS ioctl. Userspace log devices don't use dm_get_device as userspace opens them so they are missing from the list of dependencies. This patch extends the DM_ULOG_CTR operation to allow userspace to respond with the name of the log device (if appropriate) to be registered via 'dm_get_device'. DM_ULOG_REQUEST_VERSION is incremented. This is backwards compatible. If the kernel and userspace log server have both been updated, the new information will be passed down to the kernel and the device will be registered. If the kernel is new, but the log server is old, the log server will not pass down any device information and the kernel will simply bypass the device registration as before. If the kernel is old but the log server is new, the log server will see the old version number and not pass the device info.

| * | dm: add thin provisioning targetJoe Thornber2011-10-315-0/+4006
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initial EXPERIMENTAL implementation of device-mapper thin provisioning with snapshot support. The 'thin' target is used to create instances of the virtual devices that are hosted in the 'thin-pool' target. The thin-pool target provides data sharing among devices. This sharing is made possible using the persistent-data library in the previous patch. The main highlight of this implementation, compared to the previous implementation of snapshots, is that it allows many virtual devices to be stored on the same data volume, simplifying administration and allowing sharing of data between volumes (thus reducing disk usage). Another big feature is support for arbitrary depth of recursive snapshots (snapshots of snapshots of snapshots ...). The previous implementation of snapshots did this by chaining together lookup tables, and so performance was O(depth). This new implementation uses a single data structure so we don't get this degradation with depth.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dm-bufio interface allows you to do cached I/O on devices, holding recently-read blocks in memory and performing delayed writes. We don't use buffer cache or page cache already present in the kernel, because: * we need to handle block sizes larger than a page * we can't allocate memory to perform reads or we'd have deadlocks Currently, when a cache is required, we limit its size to a fraction of available memory. Usage can be viewed and changed in /sys/module/dm_bufio/parameters/ . The first user is thin provisioning, but more dm users are planned.

| * | | edac: Move edac main structs to include/linux/edac.hMauro Carvalho Chehab2011-10-311-349/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As we'll need to use those structs for trace functions, they should be on a more public place. So, move struct mem_ctl_info & friends to edac.h. No functional changes on this patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Error injection needs the pci device 0:0. So, we need to revert this changeset: 79daef2099a02fed35747c23bad22f30441133ea. Tests need to be made to be sure that refcount won't be wrong as noticed before.
