Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

ALSA: seq: Rewrite sequencer device binding with standard bus We've used the old house-made code for binding the sequencer device and driver. This can be far better implemented with the standard bus nowadays. This patch refactors the whole sequencer binding code with the bus /sys/bus/snd_seq. The devices appear as id-card-device on this bus and are bound with the drivers corresponding to the given id like the former implementation. The module autoload is also kept like before. There is no change in API functions by this patch, and almost all transitions are kept inside seq_device.c. The proc file output will change slightly but kept compatible as much as possible. Further integration works will follow in later patches. Signed-off-by: Takashi Iwai <tiwai@suse.de>

ALSA: seq: Use flexible array for device arguments snd_seq_device_new() allocates struct snd_seq_device together with a caller-specific argument area. SNDRV_SEQ_DEVICE_ARGPTR() reaches that area by adding sizeof(struct snd_seq_device) to the object pointer. Make the trailing storage explicit with a flexible array and allocate it with kzalloc_flex(). This makes the object layout self-describing and avoids open-coded size arithmetic in the allocation and accessor. Reject negative argsize values before calculating the allocation size. Current in-tree callers pass either zero or sizeof() values, but the function takes an int size argument and should not let a negative value flow into unsigned allocation arithmetic.

ALSA: seq: Use bus specific probe and remove Introduce a bus specific probe and remove function. For now this only allows to get rid of a cast of the generic device to an snd_seq device in the drivers and changes the remove prototype to return void---a non-zero return value is ignored anyhow. The objective is to get rid of users of struct device callbacks .probe(), .remove() and .shutdown() to eventually remove these. Until all snd_seq drivers are converted this results in a runtime warning about the drivers needing an update because there is a bus probe function and a driver probe function.

ALSA: seq: Bind UMP device This patch introduces a new ALSA sequencer client for the kernel UMP object, snd-seq-ump-client. It's a UMP version of snd-seq-midi driver, while this driver creates a sequencer client per UMP endpoint which contains (fixed) 16 ports. The UMP rawmidi device is opened in APPEND mode for output, so that multiple sequencer clients can share the same UMP endpoint, as well as the legacy UMP rawmidi devices that are opened in APPEND mode, too. For input, on the other hand, the incoming data is processed on the fly in the dedicated hook, hence it doesn't open a rawmidi device. The UMP packet group is updated upon delivery depending on the target sequencer port (which corresponds to the actual UMP group). Each sequencer port sets a new port type bit, SNDRV_SEQ_PORT_TYPE_MIDI_UMP, in addition to the other standard types for MIDI.
