d001544ded [ALSA] dynamic minors (6/6): increase maximum number of sound cards
Modules: ALSA Core,Memalloc module,ALSA sequencer

With dynamic minor numbers, we can increase the number of sound cards.

This requires that the sequencer client numbers of some kernel drivers
are allocated dynamically, too.

f87135f56c [ALSA] dynamic minors (3/6): store device-specific object pointers dynamically
Instead of storing the pointers to the device-specific structures in an
array, put them into the struct snd_minor, and look them up dynamically.

This makes the device type modules independent of the minor number
encoding.

6983b7240c [ALSA] dynamic minors (2/6): simplify storage of snd_minor structures
Modules: ALSA Core

Store the snd_minor structure pointers in one array instead of using a
separate list for each card.  This simplifies the mapping from device
files to minor struct by removing the need to know about the encoding
of the card number in the minor number.

2af677fc88 [ALSA] dynamic minors (1/6): store device type in struct snd_minor
Instead of a comment string, store the device type in the snd_minor
structure.  This makes snd_minor more flexible, and has the nice side
effect that we don't need anymore to create a separate snd_minor
template for registering a device but can pass the file_operations
directly to snd_register_device().

a381a7a664 [ALSA] Decentralize PM control

Each driver is responsible to get callbacks from bus/driver now.

ecbcfe36fa [ALSA] Introduce snd_card_set_generic_dev()
ALSA Core
A new function snd_card_set_generic_dev() is introduced to add the
'generic device' support for devices without proper bus on sysfs.
It's a last resort, and should be removed in future when they have
a proper bus, instead.

543537bd92 [PATCH] create a kstrdup library function
This patch creates a new kstrdup library function and changes the "local"
implementations in several places to use this function.

Most of the changes come from the sound and net subsystems.  The sound part
had already been acknowledged by Takashi Iwai and the net part by David S.
Miller.

I left UML alone for now because I would need more time to read the code
carefully before making changes there.

1da177e4c3 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!
