88e24c3a4b sound: irq: Remove IRQF_DISABLED
Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
We run all interrupt handlers with interrupts disabled
and we even check and yell when an interrupt handler
returns with interrupts enabled (see commit [b738a50a:
genirq: Warn when handler enables interrupts]).

So now this flag is a NOOP and can be removed.

9004acc70e [ALSA] Remove sound/driver.h
This header file exists only for some hacks to adapt alsa-driver
tree.  It's useless for building in the kernel.  Let's move a few
lines in it to sound/core.h and remove it.
With this patch, sound/driver.h isn't removed but has just a single
compile warning to include it.  This should be really killed in
future.

e5723b41ab [ALSA] Remove sequencer instrument layer
Remove sequencer instrument layer from the tree.
This mechanism hasn't been used much with the actual devices.  The only
reasonable user was OPL3 loader, and now it was rewritten to use hwdep
instead.  So, let's remove the rest of rotten codes.

c2cbdbb158 [ALSA] fix bootup crash in snd_gus_interrupt()
when simulating a storm of fake GUS interrupts (without actually owning
this venerable piece of ISA hardware) the driver falls over (crashes) in
two ways:
1) spinlocks being initialized too late:
INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.

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!
