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: increase the maximum number of queues Queues are used both for scheduling playback events and for assigning timestamps to recorded events, so it is easy to need quite a lot of them, especially on a multi-user system. Additionally, the actual queue objects are allocated dynamically, so it does not really make sense to have a low limit. Increase it to something still sane.

ALSA: seq: Avoid invalid lockdep class warning The recent fix for adding rwsem nesting annotation was using the given "hop" argument as the lock subclass key. Although the idea itself works, it may trigger a kernel warning like: BUG: looking up invalid subclass: 8 .... since the lockdep has a smaller number of subclasses (8) than we currently allow for the hops there (10). The current definition is merely a sanity check for avoiding the too deep delivery paths, and the 8 hops are already enough. So, as a quick fix, just follow the max hops as same as the max lockdep subclasses.

ALSA: seq: bind seq driver automatically Currently the sequencer module binding is performed independently from the card module itself. The reason behind it is to keep the sequencer stuff optional and allow the system running without it (e.g. for using PCM or rawmidi only). This works in most cases, but a remaining problem is that the binding isn't done automatically when a new driver module is probed. Typically this becomes visible when a hotplug driver like usb audio is used. This patch tries to address this and other potential issues. First, the seq-binder (seq_device.c) tries to load a missing driver module at creating a new device object. This is done asynchronously in a workq for avoiding the deadlock (modprobe call in module init path). This action, however, should be enabled only when the sequencer stuff was already initialized, i.e. snd-seq module was already loaded. For that, a new function, snd_seq_autoload_init() is introduced here; this clears the blocking of autoloading, and also tries to load all pending driver modules.
